Hi guys I just received my UHD400 yesterday (live in Brisbane Australia and it arrived in 4 working days) . Everything seems to be working fine with as far as I can tell it but I've now noticed that on darker backgrounds,I can see some sort of faint lines slowly running down the screen. Really not sure what to make of it right now. It's not enough to annoy me as I can only see it when I focus on it but it has to be on a darker image to be able to notice it at all. Any ideas what this is?

Also just tried to enable freesync but it's showing up as not supported in radeon settings. Using displayport connection and an R9 Fury so it should work. I have enabled it in the monitors OSD but still nothing. Has anyone else experienced this?

Take a pic of the faint lines. I'm not sure what's going on there. How long have you had the screen, how long has it been running?
As for Freesync, I'm running an older card, 7970. I'm not sure but my AMD settings says it's not supported either. I'll be looking to get a 1080 when they are available locally, so it won't matter anyway.

How do games look on this 4k screen at 1080p resolution? No different than a 1080p screen at the increased size? Better? Worse?

I don't notice any lag whatsoever. My history of monitors has been 60Hz models, Dell 2407WFP, a few viewsonic TN panels, so maybe I'm not the best judge of it.

re: scaling to lower resolutions, it's just like zooming in on the same scene. I have scaled down to 1440p, and 1080p in Fallout 4. No difference in quality that I can see. I scaled down to make the game smoother until I can get a 1080. At 4K, my 7970HD Radeon can only give me 30FPS according the fraps. As for Star Wars Battlefront, I get a surprising 33FPS at 4K. It dips down in heavy battles though. I scaled down to 1440p and it's playable.

My friend got the Dell 3415 about a month ago. He loves it. I was on the fence: thought ultrawide would be better than a larger 16x9 monitor. Let me tell you, I'm glad I went for this 40". I don't know how I made due without it! I had three Dell 2407's in Eyefinity, and I don't miss it.
I kept one Dell, using it in portrait mode as a side monitor.

I filmed a 4K Youtube video at different resulotions to see if there were any artifacts. I went down to 720p and it was great, just a little more fuzzy. I used an older camera, so it's only 1080p, but I'll post it online so you can have a look.

I concur with LanPirate1, this monitor upscales quite nicely. Games will look a bit blurrier if you're upscaling 1080p to 2160p but it's still completely viable on this screen. I played through a good chunk of Uncharted 4 (at 1080p) on this screen after hooking my Playstation 4 up to one of the HDMI ports. Here's a quick screenshot of that game running on here:

An update to my previous post regarding the lines. I'm definitely no expert when it comes to monitors so I'm just guessing but I think it may have been an issue relating to pwm or something. I tried turning up the brightness and they have all but disappeared now. Freesync still a no go though but to be honest it wasn't really a selling point for me anyway. I just find it odd is all. I have Acer XG270HU that runs with freesync so I know it isn't an issue with my GPU. All in all though,this monitor is probably one of the best additions to my setup I could've bought Anyone that is on the fence about buying this display,just do it,you'll be pretty happy with it I'm sure. I paid for the perfect pixel option and they delivered on that,not a dead/stuck pixel in sight. Bought mine from accessories_whole.

Regarding input lag,I'm coming from using a 144hz 1440p TN panel and I haven't had much trouble at all adjusting to gaming on this thing. I'm sure there is a difference but to me personally it isn't enough to be noticeable.

Hey guys I am really interested in the Wasabi Mango UHD400, but I just ran across the Wasabi Mango Zen U400 on ebay , I was wondering if anyone has any opinions on this one vs the UHD400, I have not seen any reviews out there. I think the downfall is that there is no Display port, but as a bonus this claims to have 4x HDMI 2, same 4:4:4, and 10bit Samsung panel. Or at the MFG site. I think the price between the two at the moment is $550 vs $400, which defiantly puts this bad boy in a jumping in range. I would like the 4x Picture in Picture, but I can live without it or the DP for the savings.

There's not much info on this UHD400 floating around the internets, but I hadn't found anything really bad about it, so I took the plunge. It showed up on my doorstep insanely quick, which was awesome. Unfortunately, that's the only thing awesome about it. After hooking it up via display port using the included cable, I was immediately disappointed. Input lag was VERY noticeable on the desktop. Reminded me of my first 24" 1080p MVA panel (circa UT3 release era) and how appalled I was at the input lag. Back then I read numerous posts about how there wasn't much if any input lag, only to feel lied to within minutes of setting it up. I was worried the same thing was going to happen with this display, and sure enough, it did. If anything, this is worse. My last display was a Monoprice 27" 1440p IPS display, the first they ever sold, and I'm at the point now where the difference in input lag between that and the 120hz TN panel I had next to it was unnoticeable without consciously trying to tell a difference. I fired up Overwatch on this thing and within 2 minutes I closed the game out because the input lag was so bad it felt unplayable.

I did notice that under "MISC Menu" under the settings, there's a sub menu called "PC Menu" that is grayed out for me. What is under that and why can't I access it? If there's any hope for this display, I'm guessing it's hiding under there. Just out of the box the display looks pretty damn good IMO, but no level of image quality can make up for input lag. As I type this, watching the letters appear on the screen feels "laggy" compared to even using my laptop. There's no way this is remotely normal. Am I missing something?

Thank you, this is exactly what I wanted to know.

Strange, I haven't seen any other complaints about lag on this monitor. Have you tried a different DP cable? I'm using a 15' cable from Amazon instead of the included cable. Have you verified that you're running at 60Hz instead of 30?

Edit: I double checked and PC Menu is also greyed out on mine...but no issues with lag on mine.

PC menu is greyed out on mine too. What does your summary on the main input show for display size, input and HZ? I can't believe you are looking at 60hz here, no way. as I type this at 50-60 words/minute, I can't see any lag at all. Just finished playing UT3 for 20 minutes, smooth as responsive as any monitor I've ever had. Either you have a defective unit, or you are looking at 30Hz.

I've not experienced input lag anywhere near as bad as what you mention above. I have noticed some slight ghosting when dragging light text around a black background on the desktop or something, but my ability to play games, including Overwatch, has been unaffected. If there is any input lag, it's unnoticeable.

No, I have not tried another DP cable, because I have never had a use for one and therefore do not own any besides the one that came with this display. I'm only on DP because my prehistoric graphics cards do not support HDMI 2.0.

Yes, I have verfied t hat I am running 60hz. 4k 60hz 10 bit 4:4:4 according to my Nvidia drivers.

How "prehistoric" is your card? It may just be that your card can't push 3840x2160 without serious dips if framerate. 4k is about 2.7x the pixels of a 1440p monitor. I'm running with a 970 and can still see serious dips in fps on some games.

Or are you playing at a lower resolution?

If you open notepad and you are typing away and seeing lag in the words as you type, something is wrong with your setup that no one else has seen in this unit. I went deeper in the menu and saw a setting called "response time". I just turned it on, it was off previously. On the desktop it's made no changes I can see. I'll try some more games and let you know.

They're 2012 prehistoric, as indicated by the "GTX 660 SLI" listed in my signature. You're correct that they cannot push 4k without serious dips in framerate, but even with the graphics detailed to nil and frame rate locked at 60 fps, the input lag is still crystal clear. Regardless, it's very appearant on the desktop, and if a GTX 660 can't run Windows at 4k, then I give up at computing. Also, 4k is 2.25x the pixels of 1440p per my application of 6th grade algebra, but thanks for the attempt.

I tried "game" picture mode and setting "response time" to "on" in deperate hope and neither made a difference that I can tell.

To the people that claim they can't feel any input lag, especially the guy claiming he can't notice much a difference coming from a 144hz TN panel, are you guys running HDMI 2.0 or DP?

This causes me a lot of concern, I already almost pulled the trigger and bought one, but I'm going to have to wait until we get a definitive answer on the input lag.

No difference turning response time on or off when playing Modern Warfare. Somehow fraps reported 91FPS in the Bog map.. And it really felt like 91 fps!
I could not use the included DP cable, as my 7970 has mini dp out. I tried the hdmi cable, but suffered through 30Hz for all of 15 minutes before running to the store to get a mini dp to dp male-male cable. I got a really short one, as I heard longer dp cables can mess with stuff. I think mine is like 30 inches.

You're correct. I was trying to do quick math in my head. Really no reason to be snarky to people trying to help you.

I've tried both a 2.0 HDMI cable and a DP cable. No difference to me on perceived framerate. The only difference I noticed is that the Nvidia control panel would only list 8-bit for color depth on HDMI, while 10-bit was able to be selected with the DP cable.

I've also used both the DisplayPort and HDMI 2.0 inputs (as well as the HDMI 1.4 input for my PS4) on this display and have experienced no issues with input lag. My previous monitor was an Achieva Shimian 1440p IPS panel. Input lag basically "feels" the same between this display and the Shimian.

I haven't noticed any terrible input lag in my few days of using it. Just finished up playing a bit of dead island definitve edition and it was running great for me. I've played a lot of rocket league on it as well since I got it and I don't notice anything like what CaptainClueless describes. Only issue I have now is the fact that even with freesync turned on in the monitor OSD it still says it isn't supported in radeon settings. Might try a different DP cable I've got and see if that changes anything.

The Shimian has no scaler and less than 1 frame of input lag... so yeah. Something is clearly wrong with that unit or the cards.
Been looking in to the WM stuff for a while also. While input lag isn't perfect, it's nothing hugely bad compared to many TVs... never heard of anything this bad.

They're pretty much my last ditch option (probably the larger of the 40" screens) if no manufacturer will get off their ass and make a freesync 40" + 4k screen that can do 10 bit, without a fucking TP Vision POS panel that has ghosting.. seriously Dell/Phillips.. wtf.

That or OLED but Dell looks to be vapourware, probably same old burn in issues in long term testing. Either that or if they're using W-OLED with colour filters, bet they're having yield issues on the colour filters at sizes below 65" where Samsung currently offers it...

That's why we are seeing burn in on new S7s already.. they can't shrink the tech enough to use W-OLED at such densities. Still RGB sub pixel OLED panels on all the phones. At this point I will never have an OLED phone until they fix this. The burn in is terrible and I see it every day on my current burner phone. Frankly shocking to see something on the market like that. IPS or nothing.

Been running an S7 Edge since day of release with fairly heavy usage, had a S2, S3, S4 in the past... literally never seen burn in. I hear about it all the time though. Must be crazy lucky, I don't know.

So for everyone last night that told me surely my display must be defective because I feel input lag... here's the truth:

IMG_0469.JPG


Left: Monoprice 27" 1440p IPS panel
Right: Wasucki Mango UHD400

Now granted this isn't the most scientific test in the universe, but still. I'm sure having to scale 1440p isn't helping the Little Mango That Couldn't, but it certainly didn't feel worse after cloning displays and having to scale than it did before. Photo was shot with a 1/4000 shutter speed. I took about two dozen photos, and the Mango lagged 15-35ms behind in all of them. I tried turning the "color bypass" and "picture bypass" settings "on" and it made zero difference. Tried changing picture mode from "standard" to "game" with the same result. Prior to performing this test, I flashed the latest firmware "Real4K0405VS", which made zero perceivable difference to my eye. Still can't access the "PC mode" menu on the OSD either...

Out of curiosity, I unhooked the Mango and plugged in my beloved old Plannar 3D vision display. It's a 23" 1080p 120hz TN panel. Running the same tests with the Planar @ 60hz, and scaling up 1080p for the Monoprice, they were dead nuts even in the half dozen or so photos I shot. I was quite surprised, I would have expected the IPS panel would have had at least a bit of lag in comparison...

So, unless someone can show me otherwise, I think it's safe to say this thing has some major lag...

First off, thank you for taking the time to post your results. 34ms does seem high for a panel which seems to be marketed more as a monitor than a television. As a TV, 34ms would definitely be middle of the road (at least compared to other models tested on rtings.

That being said, you've shown us one data point. I'm sure we'd all like to see more tests from other people to make sure it just isn't indicative of your panel. We have numerous people stating that they don't discern the lag. Two people (including myself) can't tell the difference between this panel and our older Shimian panels w/o scalar board. At this point if seems like you'd be better served returning your unit.

Good of you to test, but again, based on the number of people who are saying there's zero lag on their monitors (and 35 ms is certainly perceptible -- about 3 frames at 60 FPS if I remember right) I suspect one of several things is wrong here. Could be your cards -- most people are running these off 900 series cards, it may be something about the 600 series, some interface bug. May also be the cable you're using. Might be an issue with your specific unit. There are just too many potential points where things could go wrong here, and too many people speaking out counter to your experience to say "the monitor is laggy" in general terms.

Were I you, I'd try a different displayport cable, and if that doesn't work, return it.

Well, could someone who claims no lag test it against some other monitor, with the same timer test as CaptainClueless did?

I've been wondering the card thing myself. Doesn't seem very likely, but I've seen weirder things happen... I'll be picking up a 1080 once they're readily available anywhere and I'll retest then, along with another DP cable. But considering the amount of times I've seen people claim they feel "zero lag" on an LCD that has very measurable and noticeable lag in the past, I'm not going to hold my breath.

Sorry, my older digital slr is not too good. Anyway, am I looking at 16ms or 33ms here?

I've been wondering the card thing myself. Doesn't seem very likely, but I've seen weirder things happen... I'll be picking up a 1080 once they're readily available anywhere and I'll retest then, along with another DP cable. But considering the amount of times I've seen people claim they feel "zero lag" on an LCD that has very measurable and noticeable lag in the past, I'm not going to hold my breath.
Ran the same test and measured 17ms of input lag compared to my Achieva Shimian. It's not lag free, but it's not as bad as you seem to be experiencing. To my eye it's practically unnoticeable.

Thank you both! I caught 17ms or so in a handful of my photos. Seemed odd there was an inconsistency like that, but that's probably because it's not exactly the worlds most accurate test method. Or maybe there truly is something defective with my display causing that and exacerbating how laggy it feels. Is your Achieva Shimian a multi-input 27" 1440p IPS? If I recall correctly they had a decent big of lag over the single input 27" displays like my Monoprice, so seeing a 1 frame difference while I saw 2 sounds reasonable.

I suppose I'm one of the few overly sensitive folks out there to input lag... Even moving from a CRT to a TN panel display was a nightmare for me that took quite some time to adapt to.

It's the single input Achieva Shimian (only DVI-D).

Best I could manage. I don't have anything other than an iPhone 6 to take a picture with. Mango on the left, dvi input only Shimian on the right.

I played around with my Mango a bit more yesterday, and I'm happy to say I no long want to throw it in the dumpster. What I did might sound even more ridiculous than my original claims of this display being unusable for gaming, but so be it. I can still tell there's some input lag if I consciously look for it, but otherwise all is well in Wasabi paradise now. All I need now is some GPU power and I'll be 4k gaming happily ever after.

I was starting to wonder if my poor little GTX660 was actually incapable of truly driving Windows @ 4k 60hz. Out of curiosity, I set my resolution to 1080p to see what happened, and to my surprise, everything felt ok. I fired up Overwatch to confirm, and sure enough it felt normal. While running outlandish possible explanations for this through my head, I realized that 4k was four times the pixels, but my mouse DPI was unchanged. Never having been able to discern a difference between DPI settings in the past, I was doubtful, but gave it a shot since I was running out of possibilities. After the round ended I maxed my mouse (Corsair M60) DPI out at 5700, set my resolution back to 4k, lowered my in-game sensitivity to compensate, and hit play. Bam. That did the trick. For the first time in Mango history, I was playing Overwatch at 4k resolution and not wanting to throw my mouse through the screen while calling it a laggy POS. Everything feels markedly better on the desktop too. The cursor no longer feels like a boat anchor I'm throwing around.
