LG 43UD79 Information?

Acer ET430k has HDR?

No, it does not.
It most certainly DOES. I have a GTX1080TI connected to it and just entered the menu and it indicates "HDR" mode under picture. When you disable HDR it is nowhere near as vibrant.

christal, do you own the Acer ET430k like I do?

If so, what video card are you using, as only the most modern ones support this mode.

Perhaps this link explains it:

There are 2 versions of this display. The old one without HDR and the most recent one with fake HDR "Acer HDR Ready" (350 nits lol). So i guess you have the newer model.
 
"The old one without HDR and the most recent one with fake HDR "Acer HDR Ready" (350 nits lol). So i guess you have the newer model."

HDR10 specs require multi zone dimming, the display has to achieve at least 1000nits of brightness, and for true HDR has to feature at least HDMI 2.0a. I know that "HDR for PC" is nowhere near this, but you must have at least 500-600 nits for the whites and deep blacks around 0.05 nits, because it`s all about high contrast. Еven if there is such a feature in the menu, doesn`t mean you are going to get it. I guess presently there are simple software manipulations of the color curves without actual hardware capability.

Skline00, don`t get offended, I am sorry. The Acer is probably not a bad display, I think the panel is made by TP Vision (part of Philips) and is notorious for strong image retention... at least the previous revisions. I was put off by this and went with the LG, which has PWM dimming :)

"christal glad to hear it's good for you. I have a problem with my panasonic 4k TV (eye strain and headaches) and thinking about this monitor too and was afraid of this flickerliing a lof of guys say... I have couple of questions to you:

1. do you have a console too? I wonder how ps4 will look like on this screen in FHD resolution or even older games like MGS1 from PS3 which has a lower res. maybe you have console and could you check it?
2. I also wonder when connecting PC I would use 4k at desktop for sure but for games I would run mostly FHD because machine to play 4k is too much of an upgrade for me. How PC games look like on this monitor in FHD res?
3. What are default settings for brightness for those game modes/normal/fps1 etc?
4. I sit around 1,8-2m from my big screen does desktop of this monitor look good in scaling 200 or 300% and can be readable from that distance? (on my TV it is but would like to be sure)"

1. No, I don`t have a console and cant give you competent answer.

2. The games scale properly on this display, also in lower resolutions. There is a very nice feature 1:1 pixel mapping, which should be used in this case. I didn`t have enough time to play with the display, probably in a few days.

3. I use Custom mode, in which all settings are available for fine tuning, I also made custom ICC profile with the calibration device for D65, color temperature 6500K, gamma 2.2, brightness around 60 nits, and settings for the color channels R= 51, G=33, B=6.

4. I am myopic (nearsighted), so I cant sit too far from the screen (around 40-50 centimeters), now using scaling at 100% and feels perfect.

I have never had a problem with any displays. I have used TVs and monitors in the past from various manufactures. But now with my Panasonic 4k I have headache and eye strain (I have posted this in other thread) and I don't know is it PWM dimming, reflections from that screen (its glossy) or phosphor led used or something else...

I guess I will not know if I won't try the LG/other panel. I think I will have to buy/check new panel if it will be no good return it. With monitors I have never had problems and find them always easier for the eyes.

I never use monitors on default brightness I always change it, here at work at my HP 24 I use 40% brightness/100 and can sit at it all day.... But it varies because 40-50% brightness on my home EIZO FS2434 is very bright and too much for me.

Do you use this LG lower then 50% value of brightness? Acording to that movie on you tube with flicker in slow motion when you decrease brightness it will flicker more badly. Also can you check what are values for eg. FPS1 mode?
Also have you spent couple hours at it without eye problems or you didn't had enought time yet ?

Yes, I use it at 20% brightness in the evening, cannot notice any flickering. But this is very individual. In FPS1 you cant change response time or black stabilizer, you have to be in Custom (Game). For two days I spent more than 20 hours with the display and don`t have eye problems.
 
christal: no offense taken. Just wanted to point out that my Acer ET430k has the HDR feature. Hope you are enjoying the LG panel.
 
I have my 43UD79-B since a few days. All in all I am very satisfied. But I have a strange issue.

In very rare cases I can observe some horizontal pixel errors. Have a look at the following photo:

I figured out that these errors have something to do with the overdrive (response time) setting. I can observe those errors for fast, normal and slow setting. If I chose the off setting, such errors does not appear.

If I look at the screenshot (in Screenshot.zip) in full-screen the error is present. Have any owner the same issues or is my display faulty?

Thanks for the tip on the overdrive!

I have seen this exact thing happen on my 43UD79. It has always been so brief that I have not been able to capture a pic of it. It always seems to happen with a large black or dark area with a sharp transition into a bright area, such as having hardforum open next to white background window. Since turning off the overdrive I have not seen it happen again...

I'm not sure if I ever posted my calibration settings but they are similar. White balance is mode2, custom, R=51, G=31, B=13 which gives me 6550K but is better throughout the brightness range than having B=7 which is a perfect 6500K only at 40% brightness

PWM? Look at my previous posts and thoughts about pulse width modulation.... well, I cant say it is present... no perceptible flickering at all.
Very nice homogenity and VERY low IPS glow when viewed in a dark room wih black background. The backlight bleed is almost non-existent too. I was worried about the strange color tint on a white background some people talked about, but couldn`t see such thing.

You tell there's no PWM because you don't feel eyes tired or have you done some tests with those lines etc. ?
 
Hey Everyone,

I am seriously considering purchasing this monitor due to the versatility of it. I have a couple of questions as a monitor novice who's been running a 1920 x 1200 Benq display for the last four years. Now that I have a beast of a gaming rig with a 1080 Lightning Z and a 7700K, I feel like it's time for an upgrade!

1st: How does the KVM switch handle a MacBook Pro plugged in via USB C? I really like the idea of using the KVM to switch between my Windows Gaming Rig and my MacBook Pro, but running a USB 3.0 cable to the MacBook is less then ideal.

2nd: Does anyone have any experience they'd like to share using this to play a game like Overwatch? I don't see any reason why playing non FPS games will be an issue with a monitor this size, but I'm a little bit worried about playing Overwatch with a screen almost twice the size of my current screen on an average sized desk.

3rd: I really really really like the notion of this four screen split running. Is it possible to have two screens running off of one computer, and two off the other? That would be awesome!

4th: I've tried my best to discern some of this terminology that all of you are using with things like PWM, and I haven't the slightest idea what much of it means. If I am accustomed to a 60 hz older Benq display, will the issues with this display be noticeable to my eyes? I mean I still have to deal with CRT monitors at my job lol, so I think my eyes are probably up to the task. I feel like this monitor would be a huge upgrade, but I've never dropped this kind of money on a monitor before.

Thank you in advance for help with this. Glad I finally discovered the hardforum! The information here has been amazing.

The monitor uses PWM, unless they solved the problem with later firmware, but I seriously doubt it... Moving vertical lines at Ufotest site are not clear and single, but multiple - which is a clear indication of PWM.

I am not saying there is no PWM dimmning, just that I am not sensitive to it and that I cannot notice any flickering.

I hope I clarified this :)

I have this monitor. I haven't figured out the USB-C KVM thing. I'm just using a separate keyboard/mouse for the mac and PC on my desk. Not very ideal.

Ah ok. Have you done ufo test? It it at least smooth? And can you tell if it's worse when 50% or lower brightness?

My EIZO fs2434 doesn't use PWM at all even at very low brightness there's still one line and all is smooth. That PWM in this LG is the only thing holding me back from order it.
 
I wonder what frequency PWM uses 43ud79 can anyone check it? I have checked that problemaatic panasonic tv for me uses 250hz but I have a monitor at work HP with 430hz and it doesn't bother me at all...
 
Hi All:

i just ordered the LG 43UD79-B monitor so i don't have it yet, but i've been reading that it is ESSENTIAL to buy an appropriate DisplayPort cable for this monitor to function properly. i don't quite understand this as DisplayPort cables are supposed to be all the same from the older to the most current, yet, this Monoprice DisplayPort cable that i am currently using (NOT for the LG 43UD79-B, as i just ordered it, and don't have the LG yet) specifically says that it only goes up to 8.64Gbps data rate.

wouldn't that be insufficient for 4K and also, it specifically says that it does NOT support audio?!
https://www.monoprice.com/product?c_id=102&cp_id=10246&cs_id=1024606&p_id=6009&seq=1&format=2

Quoted directly from Monoprice's product listing page:

"...This cable supports the DisplayPort version 1.1, which does not support audio and has a maximum data transmission rate of 8.64 Gbps..."

I also have available already an HDMI cable but that one also appears to be insufficient:

"the specs on Monoprice for that cable we have is: "...4K resolution at 24Hz..."


That is also INSUFFICIENT for this LG monitor's needs, right?

https://www.monoprice.com/product?c_id=102&cp_id=10240&cs_id=1024004&p_id=4036&seq=1&format=2

does that mean I'll definitely need to order one new cable for the LG 43"?


this is confusing as the DisplayPort folks kept writing that all DisplayPort cables are the same, but they cannot be because Monoprice explicitly states that my current Monoprice DisplayPort cable does NOT go beyond the 8.64Gbps nor does it include audio, whereas the current DisplayPort 1.2a and later all support 21.5Gbps, etc.

Look forward to your reply(ies) and thank you all in advance!



 
You just never know with cables.

With HDMI, I've had cables that claim to be up to spec not work with 4K. And I've had really old cables that were included with monitors from the 1440p era work just fine. /shrug
 
Use the Displayport cable that comes with the LG 43UD79-B and you'll have no problems as long as your graphics card supports Displayport 1.2
 
You can try a 15 Ft DP cable that supports the 1.2 protocol, obviously the one you have if it's 1.1 won't support 4K and audio...I did read somewhere that the monitor will work best with the supplied cables so maybe there is something to that or just marketing...you won't know until you try and can you report your findings here either way for others that need the additional length .
 
15 feet is too long for DP connection, this in not LAN cable and quality of signal is strongly dependent on cable lenght. It`s very possible that the monitor will lose signal or blink ocassionally, etc. Nevertheless, you can buy quality certified cable of this lenght, which won`t be cheap, but that`s your best option if you cannot move the monitor closer. The Displayport cable that comes with the LG 43UD79-B is very good.

i'm not certain that this is true at all. there are many options for DisplayPort cables even longer than 15 feet.

if one were to get a DisplayPort cable that is DP1.2 or DP1.2a, or DP1.3, or even DP1.4, yet, use it with this particular LG43UD79-B, then only a portion of the available bandwidth of the cable would be used, i.e. not the full capable bandwidth of the cable. if this is indeed the scenario, then i would surmise that moderately greater than 10 feet, say around 15 feet, ought to be ok.

may i ask if you or any others have thoughts about this please? thank you in advance.

Yes, it looks like this theoretically. But in practice this particular model has its own mind, and you can read about intermittent blinking, blackouts, signal loss - all because of improper cable connection, using various cables.
LG advise to use ONLY the cables that came with the monitor. Of course, they are not the only ones that work. But you have to read the specs carefully and buy only quality certified cables, which are able to carry 4K signal @ 60Hz.
But even then there is no guarantee that the monitor will not lose connection and blink from time to time (with the 15 feet cable), you just never know.

As shown in my video, you may indeed have multiple connections from the same PC, get sent to the 43UD79-B over multiple cables, and then match them up into one mega image. Though slightly odd behavior pops up, as seen at 2:06 in my video, since the monitor thinks it's multiple computers sending the image. For gaming or video production work that wouldn't be ideal, but for general use and certain other tasks it's a valid option.


The 43UD79-B doesn't cause any strain to my eyes. But then our eyes are all different. YMMV. In any event, this is now my main monitor at home, and I plan to keep it until 120hz, G-SYNC, and HDR become available in the future at this size and resolution.

Also, I've now posted several videos concerning this monitor. And many other questions may be answered by watching. Enjoy!

Re: 10 feet to 15 feet DisplayPort cables --

May I ask if anyone else has experience with this and which cable(s) offer the best experience please?

Thanks.

I think I need at least around 12 feet to 14 feet, as my current (DisplayPort 1.1 specification, vintage 2012 cables - that's pre-DisplayPort 1.2 and later specs) DisplayPort 1.1 cables are 15 feet and i have a tiny bit of extra length that i may not need, so i'm guessing around 12 to 14 feet would be ok.

Hope some others with experience with 10 to 15 feet DisplayPort 1.2 or 1.2a and later specs might chime in with their experience.

Thx!

You didn't wanted to get SONY X900E? It is 120hz and has quite good HDR.
 
You didn't wanted to get SONY X900E? It is 120hz and has quite good HDR.

Aren't there numerous downsides to using a TV as a monitor? i. e. Non tilting stand, doesn't turn off after no signal is detected (pc turned off for the day), etc.
 
You didn't wanted to get SONY X900E? It is 120hz and has quite good HDR.
TV's tend to have horrible input lag. Also, their ports being HDMI (and other TV standards) only input 4K up to 60fps thus rendering their 120hz refresh rate a pointless feature for computer use. Now 120hz TV's can usually create extra frames to simulate 120fps (Sony brands that as Motionflow), but that takes tens of ms to compute each new frame, which adds absurd amounts of input lag, making it only a useful feature for things like movies and TV shows.

Looking at the full specifications of the Sony X900, it does indeed only input 4K video at 24hz (movies) or 60hz (everything else). Also, the LG 43UD79-B has a DisplayPort and USB-C port, in addition to four HDMI ports. Making it very useful for connecting all three of my consoles, and my primary PC and Mac. All at the same time. No swapping cables needed. Finally, my pair of GeForce GTX 1080 Ti don't output HDR using the format TV's use. The HDR standards are still a mess, to put it mildly.

You are right with this 120HZ for 4k but I saw info you can make a customized resolution for FHD with 120HZ and it works for games althrought I would need to read more about it. On DP you can make it to 4k/60hz only too so no difference between HDMI 2.2 do I really need DP? Sony has 4xHDMIs so not too bad too. As for the input lag I saw earlier a movie on you tube where some japanese guy tested 43ud79 and input lag was quite large as for monitor - average around 25-27ms. This Sony TV has 33ms which is very good because it includes HDR 4k signal and there were updates for HDR from nvidia. It's fine on LG and SONY for single player gaming like I do. If you want a competetive gaming you can't go with this LG or SONY because then you would go with smaller monitor with much lower input lag.

Im just considering this SONY mostly because:
- is it trully flicker free (only uses PWM below 8/50 backlight above is totally free - info from rtings.com test) I think this is very important even if someone is not affected by it with eyestrains/headache it doesn't mean our eyes don't feel the invisible flickering. And for me it's strange that LG removed the flicker free from their website but it's there at some shops and we all know now 43ud79 uses PWM.
- for me no optical port in monitor is a minus because I like you have consoles too and like the ability to hear pass-throught sound from soundbar connected to TV from all devices. Having a monitor I would need to swap cables from audio and but not all consoles have optical port btw.
- if you have consoles you miss a lot without HDR

Those are just thought's it's not im buying it yet just considering. If that LG would be truly flicker free and had lower input lag I would go with it 100% I think. And panel no tilting/don't turn off with PC it's a features I don't care at all.

I have an XBR49X900E, it's fantastic. Yes, it can do 120hz @ 1080p, native, no interpolation. You just create the custom resolution and switch to it, works perfectly. The image quality isn't the best at 1080p of course but in games like BF1 where you can set a resolution scale in game it helps a lot. I see RTings re-tested input lag at 1080p 120hz and show it as 16.9ms. That feels very much in line with my feeling when enabling it, cuts it in half over 60hz mode. With the TV being full array the HDR performance is also very good.

Of course this is subjective but the sheer size of it could be a concern. I have the TV as far back as I can push it on a corner desk so it's fairly far away from where I sit. I previously had a XBR43X800D in the same place and I feel it was pretty much the perfect size. If they had a 43" with the same performance as the 49" version it would be a no-brainer. Just keep in mind a 49" display is pretty huge, need to plan accordingly.

I agree on size - I currently have a Samsung 49" and feel that 43" is just about the perfect size.

So the 800E is significantly worse than the 900E? (Otherwise I'm guessing you would have gone that route)

I had the 800D (VA Panel). It's very good, no PWM at any backlight level. Input lag is about the same as well. The primary driver towards the 900E for me was the 120hz support. I love being able to play FPS on the big screen when I get the itch :) The better HDR performance was what tipped it over the top.

Yes that's a big plus for the LG but the others like this monitor flicker etc is a huge minus :)

Huh, I was under the impression that a lot of the Sony sets did 120hz. I remember first reading about it on the XBR43X830C, so just assumed that it carried over to the 800D (VA), 800E (IPS), etc. as well.
 
Today arrived mine LG 43UD79-B, actually I picked it up from the dealers myself.

VERY NICE DISPLAY overall. LG probably decided to make good all-round display and have succeded in doing so. That said, the monitor definitely needs calibration. The so-called "factory calibration" is outright horrible.... VERY cool color tempetature, probably over 13000K and offset in the gamma curve.
Once I calibrated the display using X-Rite i1 Display Pro, then... then the AH-IPS screen showed some really strong performance. Everything in terms of gradations and overtones is at the same time rich and subtle.

PWM? Look at my previous posts and thoughts about pulse width modulation.... well, I cant say it is present... no perceptible flickering at all.
Very nice homogenity and VERY low IPS glow when viewed in a dark room wih black background. The backlight bleed is almost non-existent too. I was worried about the strange color tint on a white background some people talked about, but couldn`t see such thing.

Tested the performance in some games - GTAV, Battlefield1, MAFIA III, Dirt 4.... the default response time setting in Game Mode is FAST and has unpleasant overshooting, so it must be turned off or set on NORMAL. I haven`t tested the other settings. The monitor feels fast and responsive during gaming ang is HUUUUGE which helps to get that immersive feeling.

The display scaling must be done by the GPU, which is always the better way, if you expect the monitor to do this and turn the display off and then back on, you will see that your windows have changed their places.

Another important thing - CLEARTYPE must be activated in Windows and it takes some fiddling to get it right. It must be done carefully, and it must be done SEVERAL TIMES, because Windows presumes the display as being RGB and does not apply correctly the changes initially. The screen is actually BGR and if you don`t do this part, you will see color fringe or blur in the fine fonts, but if you complete the steps, the fonts will be very sharp.

That`s everyrthing for now, I`ve tested only the Display port connection so far. Well the monitor IS INCREDIBLE, even though is not made for strictly professional use.

Calibration is absolutely necessary.



I know u can run 2 inputs on top of each other. Can we play games in 3840x1080p on this ultra wide 21:9 aspect ratio to get the ultrawide monitor affect?

Thanks.
 
Tilt: i'd like this LG 43" to come as low as possible, while still allowing access (of course) to the joystick button thingie.

The reason is that I use a movable standing desk contraption and it has the monitor a few inches higher than the desk. This additional height is NOT desirable for the LG 43", as it renders the top portion of the LG monitor to be too high for comfortable ergonomic use, since one's head would need to tilt backwards and look up substantially in order to see/read the top portions of the LG monitor.

This led me to look closely at how close the bottom of the bottom bezel of the monitor is to the desk surface, and the answer is ~2.8".

This means that while one cannot lower the LG monitor by the full 2.8" (since that would not allow easily using the joystick button), one may move the LG monitor down, with a monitor stand (non LG), by roughly 2.5" and still allow one's finger to access and use the joystick button.

2.5" doesn't sound like much but that would translate to the top portion of the LG to be lower by that much, which would mean the top portion would be more usable and comfortable to use and read at the top portion.

The issue is finding a simple MONITOR STAND that would allow vertical adjustment, and a little tilt, but not much else as I would not need any other type of pivot or swivel for this large monitor.

I did find this particular Ergotron Neo-Flex Widescreen Lift Stand 33-329-085:

Please navigate to the Downloads tab of the above link and see the top top bullet items with dimension illustrations (pdf) and Product Specification Sheet.

May I ask if anyone here have experience with which monitor stand might be able to have such significant weight capacity, offer the proper height adjustments, and be suitable for use with this LG 43" monitor please?

FYI: this is the standing desk i'm talking about:

Yep. It's a little tricky. But check out my link below for details!


Great. Thanks for the great video. Very helpful as this monitor isn't available to checkout in person in most stores.
I am debating getting this vs Acer XR382CQK. This is $300 cheaper than the Acer which is 38" Ultrawide 75Hz. That $300 can go towards a nice graphic card as well. I am not a hardcore gamer.
 
For those in the last couple pages talking about Sony for the 1080/120hz, do your research. Quite a few of the Sony models artifact at 1080p/120hz.

It is noticeable at first but goes away while gaming but I still do not like it.
 
For the flickering onthis monitor can you guys confirm it is possible to setup 100% brightness on LG to make it flicker free and then adjust brightness in nvidia control panel to comfort value?


Anyone read this test?

It's hard to understand this but it looks like it's 120hzflickering on this LG which seams quite low. Anyone updated firmware on theirs 43ud79 ?

On LG site I see only drivers for W10, anyone has tried it in Windows 7?
