I noticed that as of march 13th there is a new 43" VA monitor in town that's going for €699 in Europe.
Product page: https://iiyama.com/gl_en/products/g-master-g4380uhsu-b1/
Amazon.de (German): https://www.amazon.de/exec/obidos/ASIN/B09QGXV18B/db0001-21

This is interesting because the FV43U is a flawed monitor that goes for almost €1000.

I haven't been able to find any reviews of the Iiyama.
TFTCentral, PCMonitors.info, RTINGS, not even on Prad.de (Germany).

I'm not sure if it's even coming to the US, because I can't find it on Amazon.com but it's obviously still early days. Do Iiyama ever even sell to the US market? If not, this forum might be the wrong place to ask, but if I'm here as an EU citizen I'm probably not the only one. Have any of you got your hands on this monitor yet? I wonder if it uses the same panel as the FV43U.

I'm tempted to buy and try. I can't though because my car is out of commission for the moment. I'd be screwed in case I needed to return it.
I've used IIyama's contact form to ask the following three questions:
  • Does it have a BGR subpixel layout?
  • Did you do anything to prevent the VA brightness flickering problem with variable refresh rates? If so, what exactly?
  • What panel part is used?
  • Bonus question: Why go the extra mile to list all of the pointless extra specifications but leave out the important ones?
No response thus far but it's only been 2 days. I'll post it when/if I get it. I'll probably get a response and it'll probably be a useless one.
(Sorry I'm tired of how manufacturers treat us as like we're all braindead.)

If you find a review or have any more info, please post it here.

Alll these 43" VA monitors have some type of short comming. Some more than others. Just going by the specs on this iiyama monitor, it's HDR 400. Which is trash. That alone makes it inferior to the FV43U in terms of HDR. Who knows what other short commings it has. I will wager it's DCI/P3 RGB color space is no where close to 97% (FV43U). In short it's that price for a good reason; Like you I would like to see some detailed reviews on it. It's an attractive price but don't expect it to be better than the FV43U.

Yup. Neither have proper local dimming though so neither are good HDR. For that you'd need miniled/microled/oled anyway. Just having 1000 nits doesn't do much good without at least a couple thousand local dimming zones. The FV43U has 8 of them. So for €300 less I think a case can be made for the Iiyama if willing to accept that HDR monitors are still a pipe dream.

I'm as excited as anybody to find out how the Dell Alienware QD-OLED 34" ultrawide that's presumably coming by the end of the year will perform in terms of not burning in, as its HDR will be much better obviously but 43" is a much better size. It's kind of a choice of do I want HDR or do I want 43". In my view, just 1000 nits on its own with no proper dimming does very little to change that.

don't expect it to be better than the FV43U
I don't, necessarily. It doesn't have to be. It's 300 cheaper. All it has to be is as bad, or only slightly worse, with decent response times without noticeable overshoot. I'm hoping it might have an RGB subpixel layout for once, in which case I'd prefer it over the FV43U just based on that alone. More important to me than better but still bad HDR. Wishful thinking maybe.

Edit: the specs say HDR400 and 550 nits, so I guess it couldn't quite reach HDR600 spec and they had to call it HDR400.

Pales to insignificance compared to all the other 43" monitors and their trouble with pixel row interference. I'd put money on this thing having the same problem. I am completely shunning the 43" monitor class until this is confirmed to have been solved.

Does it have a BGR subpixel layout?
I have been keeping an eye on this monitor for a while now. I emailed Iiyama about this and they told me it has RGB subpixel. I specifically asked if it was RGB or BGR and they said RGB, so hopefully that information is correct.

I'm tempted to buy and try. I can't though because my car is out of commission for the moment. I'd be screwed in case I needed to return it.
The G4380UHSU-B1 is currently available on eBay here in the UK, so should be quite easy to return if needed as you can always ask eBay to arrange a pickup.

No response thus far but it's only been 2 days.
You should get a response with 2 days, at least i did, so if not try sending another message but perhaps leave out the "bonus" question as they may not appreciate the sarcasm. Would be good to see them confirm this is indeed RGB.

it's HDR 400. Which is trash. That alone makes it inferior to the FV43U in terms of HDR
HDR on monitors is a complete gimmick and meaningless. They simply don't have enough dimming zones, if any, to produce proper HDR. So unless you are looking at an OLED or microled, just ignore the HDR rating of monitors. It's purely a sales tactic. So the fact that this has HDR 400 vs HDR 1000 doesn't bother me at all, as both will produce subpar HDR.

I'm as excited as anybody to find out how the Dell Alienware QD-OLED 34" ultrawide
Yes, i'm sure it will be great. But you're also looking at twice the price.

43" monitors and their trouble with pixel row interference
Could you please explain what you mean by this?


Overall the G4380UHSU-B1 looks like a very decent monitor for the price. Large size and high refresh. Prices will obviously be going up in the coming months due to inflation, so i'm seriously considering getting this monitor. Just need to get a few more answers out of Iiyama first.

Thanks for your helpful contributions. It's well past midnight here so I may have more to say later, but for now I just want to quickly point out the "bonus question" wasn't actually worded like that at all, in reality it wasn't even presented as a "bonus question" to begin with. I couldn't remember the wording I used and didn't get a copy of the web form in my email inbox. I couldn't find the right words - sometimes my english, my 2nd language kinda eludes me - and needed to get the writing of the original post over with. It was more like these are important specs you guys are leaving out, that people in the know care about and you probably won't sell many units to them this way.

Thanks again. I'ma look over this thread properly again tomorrow.

Also differs from the others in not being quantum dot and HdR 400 instead of HDR 1000 which indicates no dimming features. Lower quoted contrast as well. Probably a fair price drop for those specs.

It's an issue on current 43" monitor panels where dark pixels will darken the pixel directly below it, similarly a bright pixel with brighten the pixel below. It happens panel-wide but is worse at the top and nearly non-existent at the bottom. I documented it extensively in the FV43U thread and I bought something else to replace it because it got in the way of my work.

It was also a "can't unsee" problem in certain games to be fair. At the time I was blown away by how it hadn't been noticed yet but it IS hard to explain and prove to those who don't fully understand what it is.

Are you sure this wasn't an issue with your specific panel? Strange that it would affect just the 43inch size...

And thus the cycle of people who can and can't see the problem starts again. ;)

I'd put money on it being on every single sample of every monitor model it has been found on.

There is some more info on the technical specs here: G4380UHSU-B1 Tech Specs

A YouTube video on the monitor here is in French, though auto translate subtitles are of some use.
No reply from Iiyama, but looking more closely at the that french video you linked, I see a ton of red ghosting/smearing at 4:51 next to the shadow on the wall left of the purple portal, and next to the portal itself. Pause the video with spacebar when you see the portal and you'll see it. I also see it on tree trunks when the camera moves quickly. Would that be the monitor itself causing it, or the camera used to record the video? It only shows up for fast moving darker transitions, so I think it's the monitor itself. At 4:53 again red ghosting next to shadow on the wall you jump over at the bottom of the screen. It can be seen in other spots too from 4:48 onward (the in-game footage).

Hence I am not inclined to believe it solves my biggest worry regarding the FV43U: the ghosting.

The Iiyama's got HDMI 2.0, not 2.1, which apparently means no 120Hz on PS5/Xbox at 4k, for those who care. 120Hz at 1080p.
The FV43U doesn't have the bandwidth either without DSC to be fair and requires chroma subsampling for 120Hz 4k on console PS5.

Send Iiyama another email.

As for the ghosting/smearing, I think that's just from recording the monitor with a camera. If you turn on subtitles he even says there is no ghosting. As does the product page. I'm sure there will be some degree of ghosting being a VA panel, but nowhere as bad as what it looks like in the video.

If they can't reply the first time they won't get my business. It's that simple. If I have a problem with the unit they might not reply either. I know you want me to ask again because you want to confirm information but you know just as well as I do that it would not be information we can fully trust anyway. As it won't be the product designers/engineers replying, it'd be some clueless girl working a sales support desk job doing guesswork. Probably remotely, from India. She'll ask a coworker the questions, copy the answers and they'll have a 50% chance of being correct. Flip a coin.

If you turn on subtitles he even says there is no ghosting.
He's just reading off the spec sheet when he says that. "We also have the 4 milliseconds which allow no ghosting." It's a large VA, so it's not going to be 4ms in reality and in reality it will ghost. If he actually tested or paid attention to it he wouldn't just be regurgitating what the manufacturer claims. Still not convinced it's the camera recording because I've seen other recordings of monitors that don't show these red trails. And it's only happening for dark transitions. If we're going to dismiss it we'd need a way to explain why a camera does that only for dark transitions instead of the entire scene, it doesn't make any sense. I've also seen an FV43U user show this same red ghosting on video to ask other owners on Reddit if it's normal because that's what he was seeing IRL. He ended up returning the monitor. I can't definitively say it's not the camera, nor that it is, it would certainly be an odd ghosting effect that I wouldn't expect from a monitor, but I won't rule it out without a better review.

Edit: Here's an example of pixel response sluggishness on VA showing up red: https://www.reddit.com/r/ultrawidem...is_typical_for_ghosting_or_black_smear_on_va/
Quoting what he wrote: "edge of rock against sky smears/breaks up red when camera pans left."
So clearly red is what he's seeing IRL. And that's exactly what we see in his recording:

Note the red outlines. Make those 5-10x worse and you've got what's in the worst moments in the french video of the Iiyama...

Here's another example. Look at the fence, it turns more red as the camera moves.
There is also a red outline next to the wooden electricity pole behind the fence if you look closely just before the view hides it back behind the metal/concrete pole that's in front of the fence.

My preliminary conclusion is that the IIyama ghosts so badly that you assumed it had to be a camera-recording-a-screen issue.

Well to say for sure will need to wait for reviews. But i've had a VA monitor for years, using one now, and have never seen ghosting anything like that before.

Might be different on a bigger sized monitor, though the Iiyama has much better specs than my current panel.

Got a great deal on an FV43U at €699 and picked one up. Here's a pic. It's blurred because I panned my phone to keep the tree in front of the lens, while moving the mouse to move the tree across the monitor. See red outline right of tree trunk:
IMG_20220416_125632_cr.jpg

I see it IRL too, it's what these big VA panels do. No amount of overdrive seems to be able to get rid of this red/magenta ghosting.
It does not occur on everything, mostly tree trunks, wooden barrels... It's not overshoot because disabling OD doesn't remove it.

There is black smear as well on my FV43U, where that's most apparent is on foliage/shrubs.
Not too distracting unless I increase the sharpness in the OSD which effectively creates more, seperate, thin strands of foliage against whatever the background is.

I see what you mean. How much of an issue is this in actual usage though? Is this something you only notice if you are really looking for it?

Bearing in mind the limitations of the technology, i guess a larger screen makes such flaws more obvious. But if i recall correctly from the Hardware Unboxed review, the FV43U uses BGR subpixel and they didn't seem that impressed with it overall. I wonder how the Iiyama would compare?

The alternative is IPS, but then you have issue with IPS glow and poor contrast. And i don't think IPS panels come in this size?

Of course OLED is best, but expensive and has burn in risk.

Aside from the ghosting/smearing you described, how are you finding using such a large monitor? Have you got used to it yet? How far are you sitting away from it?

As you just got the monitor and are within the return period, have you considered getting the Iiyama monitor and doing a direct comparision between the two? Then just send back the monitor you don't like.

It's not an issue in actual usage. You don't notice when you're actually focused on playing the game. If the player has decided that any ghosting is going to annoy them, then they can probably find some to be annoyed about. The bit of ghosting is worth having and ignoring in exchange for the contrast ratio of VA vs IPS. I say this as a former PG279Q IPS user with a background in highly competitive Unreal Tournament, when CRTs that didn't ghost at all were the norm. So if the motion is good enough for me, it should be good enough for almost anyone. As long as you're using the correct OD setting for the Hz you're running at, even the red ghosting is reasonably controlled enough to not be a distraction.
I expected general motion unsharpness to be a bigger issue, with this panel compared to the IPS panels I've used. Thus far I can't say that that's the case. All sample & hold panels have motion blur because of how the eyes work, so what you do is refocus after you whip your in-game view around, just like you do when you turn your head IRL. There is something to be said for a fast response panel, but there's definitely more to be said for a huge, higher contrast panel while paying half the price of a 38" UW IPS monitor that's literally half the size (only the bottom or top half). I don't think I'll be going back to anything smaller, not to IPS either.

Bearing in mind the limitations of the technology, i guess a larger screen makes such flaws more obvious. But if i recall correctly from the Hardware Unboxed review, the FV43U uses BGR subpixel and they didn't seem that impressed with it overall.
They make the same mistake I used to make: focus too much on speed at the expense of all else. Size and resolution matter more than anything else. It depends though.. if you're into esports and only care about winning or losing then there are better options, if you're half way through your life and it's time to chill with max immersion in single player games, no regrets. After tweaking ClearType, BGR isn't really an issue anymore, only noticeably degrading text in applications that ignore ClearType settings. Which in theory includes games, but I have yet to have an issue in a game. (Disclaimer: I have only had the monitor for a few days.) Text on the Aorus could definitely be better but that's not all due to BGR alone. The QN90A 50" is said to have better text and that's BGR too, so there are obviously other factors involved in that. Even on the FV43U, if you're going to use 125% scaling because you're gonna sit 3.5 ft away, then text is great regardless. I'm currently sitting close enough that I'm using 100% scaling. At 100% text isn't as clear as on my 27" 1440p IPS monitor. I'm going to experiment with a custom scaling setting at 113% to see how that goes. At 125% I lose too much 4K desktop real estate. I expect some things to look blurred at 113% so it appears that the best options are to either wall mount the 43" to get more viewing distance and use 125% scaling in the OS or scale only the text size in the applications themselves individually so you don't scale any of the UIs and save some of that 4K screen real estate.

2160p for the desktop is definitely the way to go, even if your GPU can't run most games at 4K. If you need more fps you just configure a custom, lower resolution, whichever you would also have used if you'd bought a monitor specifically for that game+GPU combo. Display it 1:1 without scaling and you're good to go. You don't lose anything compared to having a smaller monitor, the result is the same, just with black bars instead of the bezels being right at the edge of the image - which to me doesn't matter in the slightest. I can run most of my games at 4K but even when you can't, you still get that 2160p for the desktop which is excellent compared to a 1440p panel, ultrawide or otherwise.

I wonder how the Iiyama would compare?
Unfavorably, most likely. It's more of a low budget option is the feeling I get from the specs and what Iiyama have been doing lately.

The alternative is IPS, but then you have issue with IPS glow and poor contrast. And i don't think IPS panels come in this size?
Text is excellent on my PG279Q but I can't stand IPS anymore. I got tired of the glow and not being able to see where I was going in dark games. Prominence is a hidden gem that starts you out on a space vessel running on backup power. Until you start the power generator to turn the main interior lights on, many scenes are just washed out grey rectangles on an IPS panel. That's not to say VA panels solve that problem completely. They're noticeably better at it but the contrast is still limited, both are LCD technology so they are more alike than they are different.

Of course OLED is best, but expensive and has burn in risk.
Burn-in means I won't even attempt to use one as a monitor, but there are several other reasons too. OLEDs aren't suitable for (PC) gaming because of VRR brightness flicker. They do not have the variable gamma curve that would be required to prevent that, and even LG admitted to that by publicly announcing that they will not be able to solve this issue. OLEDs also use PWM to control the brightness, so they aren't "flicker free". They probably aren't the kind of display you want to use all day for the OS, your spreadsheets and webbrowser. It should be mentioned that PWM can have an advantage in motion blur reduction, but if the Hz of the PWM flicker is mismatched to the refresh rate, it can result in double images in motion. What sucks it hat you don't get control over it with TVs, for instance a QN90A (which has PWM, the fact it's a VA is irrelevant here) will flicker at 960Hz outside of game mode, at 960Hz inside game mode with VRR, at 120Hz in game mode without VRR, and again at 120Hz if you use the Dynamic, Standard, Natural or Filmmaker picture modes, or if you enabled Picture Clarity settings. OLEDs also don't get bright enough for highlights to be very impactful. Some players prefer LCD over OLED because the high brightness is useful in more scenarios which includes brighter room environments where OLED can feel subdued. Most games try to stay away from extremely dark scenes. OLEDs have ABL, automatic brightness limiters, which get annoying when using the OS to read documents. OLEDs use twice as much power as LCDs at the same brightness. And they can have terrible stutter with low fps content because of the near instant pixel response, as each image is on screen for longer that way instead of smearing them together. Nobody likes to talk about any of these things. The flaws of VA and IPS are mentioned all the time, while those of OLEDs are typically not mentioned or thought about. It's a cultural problem. If it's new tech you have to have it now. What, you aint got one yet? Got money problems you hobo?

As one unfortunate buyer wrote somewhere on the internet, and I quote: "Don’t buy OLED, it is amazing at first but the burn in is the biggest kick in the ass. My less than 3 year old LG has OLED burn in and I don’t do long time channel watching with logos. I’ll never buy OLED again."

And another, about LCD brightness having that punch that OLED lacks:
"C9 owner here, purchased the QN90A today. Blown away by the quality of this screen. As expected, quite poor blacks and contrast, lack of shadow detail. Most titles I play stay away from extremely dark scenes. The C9 remains my go-to for movies with the family and specific games that I'd want to play at night, but I can see the QN90A being useful in more scenarios, at least for me."

Aside from the ghosting/smearing you described, how are you finding using such a large monitor? Have you got used to it yet? How far are you sitting away from it?
I haven't VESA mounted it yet so my eyes are only about 2.5 ft away right now, slightly too close but in terms of width for immersion I wouldn't mind having that same FOV to the sides as I have now, so I could even use a 48" or 50". I would be OK with this same, relatively acute angle to the sides that I have right now for immersion's sake in games (sitting relatively close to a large panel), but in the OS it's a bit too close because the FV43U has really bad viewing angles, washed out look to everything on the sides / corners so it's pushing me back further than where I want to be for the limited physical width that it's got. In-game you can sit closer than you'd think because you're not going to notice. I would say 3 to 3.5 ft would be ideal. A 43" isn't as big as I had made it in my mind. I'm actually on the fence about trying a QN90A 50" to see how it compares. A slightly wider, less tall aspect would be better, but 21:9 isn't tall enough for me even at 49" so the "one size up" available is 16:9 at 48"/50". I wouldn't go larger than 50" though unless you're sitting on a couch.

As you just got the monitor and are within the return period, have you considered getting the Iiyama monitor and doing a direct comparision between the two? Then just send back the monitor you don't like.
I have considered it, yeah. The FV43U has superior specs and there are in depth reviews of it so I know what OD mode to use at what Hz and other useful bits of information. I got the FV43U for €699. So at that point the topic of this thead: ..."significantly undercuts price of FV43U" was no longer true for me. I got the Aorus at a very similar price to the Iiyama which by contrast has no in depth reviews so I wouldn't know what to expect and it'd most likely result in having to return a very large object, which comes at a cost (doesn't qualify as a regular size package) and is a hassle. There's room for improvement over the FV43U but I didn't want a low budget version of that so I went with my gut. Iiyama could've replied to my message and told us for what reasons they decided they needed to add another 43" VA option to the market and why theirs is better, except they didn't so I am just going to assume that it's got all the same flaws, plus a few of their own due to budget cuts. It doesn't feel right to take advantage of return periods to do tests knowing beforehand that I'm going to return one, because the retailer ends up having to eat the cost of having to sell a monitor at reduced price because the box has been opened.

I see what you mean. How much of an issue is this in actual usage though? Is this something you only notice if you are really looking for it?
It's annoying.... can't unsee it in every game I try. If both the Iiyama (as I noticed in that french review youtube video) and the FV43U do this, then all 43" BGR VA's likely do it. And by "it" I mean dark smearing that becomes red / magenta. I'ts like the red subpixels are slower than the green and blue ones or something.

There is not a single refresh rate or overdrive setting that can get it under control. The only thing that seems to help is reducing red saturation a lot. It does have a LOT of red saturation to begin with, but it still requires dialing down more than what would give you a natural looking image. To stop the red ghosting you have to almost make it black & white or only green/blue/yellow. At 85Hz it's better controlled than at higher refresh rates (still not great) because due to the lack of variable overdrive the overdrive is stronger at lower refresh rates, and at 60Hz there is way too much overshoot. So that makes the FV43U an 85Hz monitor despite that the spec sheet says 144Hz. If that's true for the Aorus it'll be true for the Iiyama as well. However, the 34" Iiyama VA does to better than its 34" VA competition in terms of response times so perhaps that could be true for the 43" Iiyama as well compared to the 43" competition. Can't say until a proper review shows up.

The weird thing is dark shadows in plants, grass, trees etc dark smear slightly without ever turning red. The red trailing shows up when dark tones in motion close to browns or greys (probably midtones in general) need to become brown or grey / midtone.

Reddit post from another VA user:

Asus TUF vg24v 144hz red trails​

I just bought a monitor of the specs above. It works great except that for certain games, e.g. sea of thieves and Minecraft, after a short time there is dark slightly red trails that follow every dark object. I’m not sure if the monitor is defective or if my rig is just struggling

Speaking from first hand experience with VA panels, no it is not inherent to VA. Only some VA panels do this. And it's really, really bad on my FV43U. :cry:

Edit:
That Amazon review is great so I'll put it here:
1651414785918.png



The Polish review doesn't teach us much new information. They did measure 'entire system inputlag' and said it's nothing out of the ordinary but did not measure at different refresh rates nor mention at which refresh rate they did measure. You'd have to assume 144Hz.

Conclusion of Polish review, Google translated to English:
The VA matrix used here deserves praise in terms of image quality - color reproduction, gamut coverage, very high contrast or maximum brightness exceeding 600 nits. It is true that HDR is still not at the level to which we are used to TV sets, but it is quite decent. The panel is also quite fast, especially when we play with the afterburner or, alternatively, with the strobe backlight mode (although this, for our taste, involves too many compromises). Still, you have to remember that this is VA, so smudging is noticeable with highly contrasting objects. The properly working FreeSync / G-Sync and relatively low input lag are also a plus. The disadvantages include the average speakers (this is the standard), castration against ProLite models with PiP and PbP options or adaptive synchronization only in the range of 48-120 Hz. At the end of the day, the iiyama G-Master G4380UHSU-B1 Red Eagle is a truly competent monitor for players, so if someone dreams of "something bigger" for a desk or a display for playing in the living room, but does not have a rubber budget, this equipment can really turn out to be real good choice.

The panel is also quite fast, especially when we play with the afterburner
Kinda funny. Overdrive got translated as afterburner.

The properly working FreeSync / G-Sync and relatively low input lag are also a plus.
I'd take that with a pinch of salt as most reviews, both user- and professional ones, almost always fail to report that a panel has VRR flicker while nearly if not all VA panels on the planet have VRR flicker. So does my FV43U, which is supposed to not have any also according to Hardforum's thread dedicated to that model. Too many people don't know what they are doing when it comes to g-sync, frankly. Turn it on and assume it works. I wish it were that simple. With g-sync actually functioning you also need to throw some intentionally challenging scenes at it to ensure that you weren't just lucky in whatever game was used in the review. Scenes with brightness changes. Candle light, highlighting bright UI elements, flickering lamps to see if the panel amplifies it a lot (like every VA I've seen), etc. My FV43U doesn't like candle light and also flickers when you highlight a white UI element by moving the mouse over it even if it's just the size of the tip of your pinkie. Mostly the right half to third of the panel then flickers, not too bad though compared to a G7 let's say and on the left side it is very subtle. It was still enough for me to switch to v-sync instead of g-sync. If the Iiyama has the same panel with a different strength of backlight maybe you should expect a similar result.

The red ghosting visible during gameplay in the french video review linked to by July2002 for me already put the nail in the Iiyama's coffin.

Oh I hadn't noticed he wrote in the comments: " I think it comes from the camera which films in 60 fps a screen going from 144 fps. " He's unsure and I don't believe his assumption because to accept it, someone would have to explain to me how a frame rate difference could cause a change in COLOUR. That does not make sense. A video may cause seeing multiple frames at once or appear stuttery but it's not going to colour red only edges and only those that are in motion.
When I make a video of my monitor with the same video-fps and Hz combo nothing turns red, until the image on the monitor moves to MAKE IT have red edges because my FV43U has red ghosting.

Edit: I just looked at his ingame footage again and trust me the FV43U I've now used for a while does the exact same thing. I recognize it instantly. His video recording just makes it look worse because it's showing you multiple frames at once. He wasn't paying attention.

quick post, that might interest the others waiting for a real review of the G4380UHSU

after seeing the amazon customer review saying:
And the PSU buzzes. I can hear the monitor buzzing above any fan noise coming from my desktop PC - it's that bad.
i thought i reach out to iiyama support on what they say about this. i also asked them like 2 months ago about whether the display is actually RGB subpixel layout, which they said IT IS.
their response on the potential PSU buzzing issue:
Dear Customer,
Thank you for your email.
A buzzing power supply is not normal, so far, we have not received any complaints about this.
whether the support is telling the truth, i can't say of course, but i bet lots here would still be interested to know the response from iiyama to that.

I wouldn't have thought the loud psu buzzing is normal. Did you link them to the customer review on Amazon?

I also asked about the RGB layout. And they told me it is RGB.

For the money, I think this is the best you're going to get for a screen this size and high refresh. Not perfect, but good enough.

New Customer Review - https://www.ldlc.com/en/product/PB00480939.html

This is the model I've been waiting for years to replace my current 43" Philips 60Hz. On paper this iiyama ticks all the right boxes, VA, 144Hz, Freesync Premium, 4K, all at a great price.

My configuration is Ryzen 9 3900x, RX6700XT, 32GB DDR3600Mhz. The screen is connected to DisplayPort and the display is in 10bits RGB444 full range from the first boot.

By default, the screen has overdrive disabled and is adjustable to 5 levels. Playing without overdrive is not recommended because of the visible ghosting. It is also not possible to play with the overdrive set to 5 because of the overshoot (reverse ghosting). With the overdrive set to 1, the image is clear. Overshoot will depend a lot on the game and the type of scene (contrast, lighting, colours). On most CSGO maps, I can set the overdrive to 4 without seeing the overshoot, which gives very sharp images of movements. Elden Ring is a very overshoot prone game and I find that the optimal setting is 2 or 3. Whatever the game, the sharpness is very satisfactory thanks to a well graduated and very effective overdrive.

To sum up:

+ VA panel with a nice contrast ratio
+ 4K up to 144Hz max
+ very good input lag
+ very good fluidity felt
+ homogeneous image without light leakage
+ sharp image
+ good overdrive
+ Freesync Premium (LFC functional)
+ efficient matte panel
+ good value for money (the cheapest in its class)

- remote control not easy to use
- overshoot present on some game scenes despite overdrive

+- HDR ok without being exceptional
+- neutral colours that need careful adjustment for more vibrancy

A screen that I would recommend to any enthusiast gamer who plays in 4K.

just wanted to say, that i wrote a nice long response to you, that included the original email from me and the answer from iiyama to give you the clearest picture on what they said through full contrast basically, but for whatever reason it still doesn't show here.
maybe it was auto flagged, because it contained 3 links, or maybe it got censored away for some reason.
either way i tried and i guess hardforum sucks :/

Could have been a technical issue.

But what was the general summary of what you were trying to post?

Someone has this monitor?
Can you tell me if it is possible to take off this piece of plastic (watch the pic).
Thanks.
