LG 43UD79 Information?

At 4k resolution does this do 60Hz or 30Hz? I saw a comment on another site this LG only does 30Hz when in single display of 4k
 
I have seen a couple of YT reviews of this monitor. It doesnt have HDR though correct?
 
I just got the LG 43UD79 and for those who have it, do you notice any tints / hues on one side of the monitor or the other when looking on a pure white screen? (i.e google homepage)
It seems the left half of my monitor has a light pinkish tint while the right has a light greenish tint. I'm not sure if I should return it or not....
 
I got the LG 43UD79-B a few months ago. Its a great monitor! I just posted a rather lengthy video on YouTube about it, which includes monitor unboxing and setup, gaming benchmarks with a GeForce GTX 1080 Ti, monitor feature guide focusing on multiple devices on-screen at once, and final thoughts. A massive fifty minutes worth!

Notes:
1. A Playstation 4 Pro will output 4K to this monitor, and looks great doing so. But there is a trick to make that work, as your only choices to start with are 720p and 1080p (4K will be greyed out). See the other LG 43UD79-B video on my channel for a short how-to guide.

2. Not all USB-C cables are created equal. Some only work at USB 2 speeds, and will NOT drive this monitor. The "charge cable" that comes with new MacBooks and MacBook Pros is one such example of a USB-C cable that won't put an image on this screen. So make sure it is a USB-C cable fast enough for 4K at 60hz before you buy it if you choose the USB-C hookup in back of the monitor.

3. Though the monitor is advertised in some places as able to charge devices over USB-C, I could only get it charging my 2016 MacBook Pro 13" at 7W. Not enough for almost all devices. Especially a proper notebook. I verified all of my USB-C cables could charge my 2016 MacBook Pro 13" at 60W when connected between the notebook itself and its own AC adapter. So, unless I'm missing something, don't count on this monitor to charge your devices.

4. My apologies for using a GoPro, complete with its distorted settings. It's the least lame option of what I could get running at the time.

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:
photo.jpg


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?

Hello to all
For those who are interesting there is now the first extending review for this monitor in the esteem website prad.de
http://www.prad.de/new/monitore/test/2017/test-lg-43ud79-b.html#Einleitung

Their final verdict is very positive. It is very rare for prad to give 5 stars and a very good mark. It seems that this monitor delivers only a good result (which still is meaning that it is a very good monitor) but takes the fifth stars because of the very good relation between quality and price.

In brief: the positive
Very good viewing angle and a quality IPS panel despite its low price
Very good homogeneity if we consider the magnitude of the panel
Decent result after calibration
Good build quality

There is not something unacceptable in this monitor, according to the test, even if the calibrating contrast is only 782:1.
There is a mention that it uses, as we already now PWM (but it seems it is not annoying at the calibrating settings with a frequency of 119 hz.) Please owners of this monitor confirm if you feel/or not any inconvenience for daily office work- especially in word environment.


This is the calibrating settings from the pdf file

The target

White Point (CCT) 6494 Kelvin
White Point XYZ (normalized) 94.99 100.00 108.66
DeltaE to D50/ D65 19.37/ 0.17
Assumed Target Whitepoint (2) 6500 Kelvin
DeltaE to Assumed Target Whitepoint 0.08
Brightness 140.78 cd/m²
Black Point 0.18 cd/m²
Contrast (x:1) 782:1
Gradation (Average) 2.18

And the results:

Brightness 54
Contrast 70
RGB 50 34 9
Gradation Modus2


There is also two less detailed test in http://www.pcgameshardware.de/Monitor-Display-Hardware-154105/Tests/LG-43UD79-B-1234286/
and another one in http://www.chip.de/test/LG-43UD79-B_120376114.html

I am not a native German reader, so i suppose, especially as it regards the prad review, that we can have a more accurate picture from a german speaking member of the forum.


I hope I've been helpful.
 
Can i split the screen with two sources one running at 4k ( my PC) and one bluray player at 1080P ? side by side split.. thanks

You can have your PC running at 1080p and your blurry player running at 1080p, in side-by-side mode.

If you really want your PC showing you a full 4K, you could leave it taking up the whole screen at 4K, then have your blurry player at 1080p using picture-in-picture mode.

See my "Epic Review" at 34:47 to see me messing around with different options as such.

thanks a lot one last question .. is the VX4380-4K viewsonic better than this lg ?
 
"There is a mention that it uses, as we already now PWM (but it seems it is not annoying at the calibrating settings with a frequency of 119 hz."

If the monitor is flickering at 119 Hz, it will be VERY ANNOYING, believe me. Especially after prolonged use. Do you think the reviewers have spent more than few hours in front of the monitor, so as to take their word as gospel?

Hi Christal: Thank you for this observation. This is the reason why I ask the owners of this monitor to verify if they facing any eye-strain/headaches or other pwm implementation related problems with their units. I understand that this kind of problems are not affected all users in the same way. However, as I am use to “flicker free” or allegedly flicker free monitors (my current is a benq BL3200pt), my work requires 8-12 hours per day in front of a computer monitor for reading or writing word documents, and I have sensitive eyes, I am asking for this clarification.

And another one, I hope not off topic, question.
In the absence of more thorough reviews of LG 43UD79, is it possible to determine from what brightness settings flickering is appear? I wander if flickering is not present from 100% brightness then couldn't be possible for software like iris (https://iristech.co/brightness/) which reduces the emitted light without changing the frequency of the backlight, to be useful for this particular monitor?

Thanks again for any answer.
 
Your monitor is not "allegedly" flicker free, BenQ make some of the best backlights in the industry in this respect.
On the other hand, in the backlight dimming of the LG 43UD79, they implement the so-called "black frame insertion", which leads to obvious flicker in the ENTIRE brightness range... This is probably a cheap way to comply with power consumption guidelines...
A big "no-no" for your line of work.

I will post this again:

VX4380-4K
The VX4380-4K has a response time of 12ms according to their own website. While I haven't used that monitor at all, that would be horrible for gaming if that stat is accurate. Would probably create a good bit of ghosting.
http://www.viewsonic.com/us/vx4380-4k.html

The LG 43UD79-B claims to have a response time of 5ms. The best an IPS monitor can have. That's over twice as good as the Viewsonic monitor when it comes to reducing ghosting in fast moving scenes. And from my experience gaming on this LG monitor, that seems accurate.
http://www.lg.com/us/monitors/lg-43UD79-B-4k-uhd-led-monitor

Still, if you're looking for the ultimate gaming monitor, for hardcore twitch action first person shooters, anything with a response time over 1ms, or a refresh rate under 120hz is out of the running. That being said, such monitors use TN screens which look horrible when it comes to colors. IPS screens like the two I mention above, are superior for everything except gaming. Still, if you're a really hardcore gamer, consider this TN display below. Complete with a low 1080p resolution so your GPU can push out four times more frames-per-second while gaming than it could for a 4K monitor:

While it's true most "reviewers" only toy with a product for a couple hours (while reading a press release almost verbatim) before shipping it back, this is actually my main desktop monitor now. I use it for my Mac, Windows gaming rig, and consoles. As a geek I've used it quite heavily these past couple months, and have had no eye strain as long as I keep the brightness low at night, and half-bright by day. Seriously, most eye issues seem to be a result of almost everybody I meet cranking their brightness up to 100, all day, every day. Drives me nuts! Seriously, I'm an IT guy, so I see a LOT of monitors at work, and the first thing I do is turn down the user's brightness level by at least 50 points before I do anything else. My eyes, why must my users burn them?!?

Anyways, that being said, I do get migraines using ancient LCD monitors with fluorescent backlighting, at any brightness level. Nobody else I know does, but they usually hurt my brain within minutes. Meanwhile, I've never had problems with an LED backlit screen, such as this one. While some people are sensitive to many of them. Our eyes seem to be tuned differently, so all I can say is this monitor isn't causing me health issues at this time. YMMV.

The problem is that whenever a company mentions response time. They are lying.

12ms could just be exactly what the panel manufacturer says it is and Viewsonic doesn't care to change it, yet overdrive may exist that does bring it much lower.

Example, those 1440p 165hz IPS gaming monitors say 4ms, but the panel they use from the AUO factory says 12-14ms on specification (Cant remember which). Which is reduced later with overdrive. TN monitors usually write 1ms on the box, except there is not a single monitor on planet Earth that can hit 1ms g2g average, nor even 2ms. 240hz TN monitors average 2.5-3.5ms for instance.

TLDR: Response time quotes are bullcrap.

That`s good to know, thanks for sharing your experience. I wonder why you don`t have issues with the flickering at half brightness. I use monitors for photo editing at around 60 nits, which corresponds to ~ 15-20% brightness on the 43UD79.

I fear that the flickering will be very pronounced at this level...
 
I have been reading this topic for a while, and eventually decided to buy the 43UD79 for home usage as the price is now 570 Euro's over here. After a few days of using the monitor i can share a few things from my personal experience.
At work i'm using 2x Dell 2715H 2560x1440 monitors and at home i had been using an Acer 26" screen running at 1920x1200 for 10 years. So, the LG is quite big when setup at the desk. I'm running the brightness at 40% and must say the image quality is very good.
As mentioned before by others, at the sides, there is a small dark shadow but it does not bother me. I was most worried about the flickering caused by the PWM everyone is talking about. I did not notice any flickering at all and find it hard to believe the PWM is running at 120hz. I'm no expert but can only imagine the frequency is much higher like 1200hz or something... For now, i'm very satisfied with this monitor.
 
I have had this monitor for a few days now. I'm coming from a Dell 34" U3415W, which has two upstream ports. This allowed me to easily connect a keyboard and mouse to the monitor, and have the keyboard and mouse automatically work my pc/mac when I switched display inputs.

Unfortunately this monitor has 2 Downstream ports and only one Upstream port (USB-C).

What would be the most efficient way for me use my keyboard and mouse plugged into the display without having to switch the upstream USB cable between devices?

Is there a trick to enable 4k @ 60hz over HDMI 2.0 on this monitor?

When I use my HDMI 2.0 cable to connect to my PC, it defaults to 30hz with no option to switch to 60hz.

If I change the 'picture adjust' setting in the display menu for 'HDMI ULTRA HD DEEP COLOR = ON' 60hz will display in the display adapter settings. But then the display looks like crap.

Am I missing something here?
 
HDMI 2.0 and DP 1.2 both support 4K@60 Hz. Do you use the cable that came with the monitor? Check in the manual in case you missed something.

It's not a cable issue (I'm using brand new HDMI 2.0 cables that I purchased). 60hz works fine. It's just weird that I have to enable "ULTRA HD DEEP COLOR" for both my pc and my mac to switch to 60hz. I'm curious if anyone else has seen this.

Another thing i'm curious about - has anyone tested a mac using the USB C cable to drive the display? I would like to know if that will work w/ 60hz....

On a Mac the USB-C will drive the display at 60Hz, but it will not charge the Mac.

P.S. From another forum regarding the YCbcr 4:2:0 configuration in 10 bit mode:

"RGB or YCbCr 4:4:4 is basically the same thing. Just make sure it's not Studio/ Limited YCbCr.

YCbCr 4:2:2 subsamples colors a bit so theoretically there's a decrease in color quality but it would be pretty difficult to notice the degradation.

YCbCr 4:2:0 is the format movies are encoded into (bluray, dvd etc) - if you play such content visually you shouldn't notice any difference. However, in games, in Windows, you would definitely notice the loss of color information especially at texts (it would screw up a bit antialiasing of various fonts, colored texts on colored backgrounds ex blue text on red background would be screwed up)"

This guy did a similar to trick to what I posted to get his PS4 Pro to display correctly on the LG. I had the same experience w/ the PS4 Pro, and my mac.

They both work fine, it was just tricky to set up.

 
I have read posts about PWM flicker but does this monitor actually bother anybody eyes?

I have an issue with panasonic 4k TV (headaches and eye strain) and searching for a panel for me...
 
So, do you guys reccomend this for FPS TPS, casual gaming? or should i wait for the PHILIPS 436M6VBPAB ?

A big YES, I've had the 43UD79-B for just over a month and can't complain about anything, I do 3D w/ Maya, editing w/ Premiere and it's an incredible monitor! The vanishing of ethan carter in 4K is amazing...that being said the lack of HDR maybe a deal killer for some so if that is the case the PHILIPS 436M6VBPAB maybe the answer but rest assured that it will come at a premium in the pricetag as well, I've even heard that people are getting the LG over more expensive monitors that just don't deliver like this baby does!
 
How does the acer et430k compare to this?

Also, how are the speakers? Can they replace a $20 set of computer speakers?
 
silverwolf0, I own the Acer ET430k and am very happy to have a 4k monitor that is so big. However, it does not have all of the features this LG does. It does, however, have HDR and that makes a big difference for me.
 
The speakers on the 43UD79-B are very good and IMO much better than a cheap set of computer speakers....as for the Acer ET430k after looking at the info available I see no mention of it having HDR and it seems to suffer from image retention as well, the LG is not much more $$, skline00 can you confirm the HDR? That would makes it the only 43" w/ HDR currently?
 
Does HDR make a different in bluray movies? Where can I see the difference between HDR and non HDR? Even on youtube videos it's visible?
 
After researching for weeks, just ordered LG 43UD79-B. Thanks for all the contributions and information everyone :)
 
So is the older bdm4350uc using a different panel that's not LG made? And the 43ud79, et430k, and vx4380 all use the same LG panel? Which one is better ?
 
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.

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)
