I saw a short youtube video talking about this monitor recently. It's up for preorder on Adorama for $700, which would be significantly cheaper than other 40"+ 4K monitors. Someone on OC.net said this was the same panel that was in the Crossover 430, but I don't know if that's true.

Has anyone heard anything about this monitor? Possible release dates? There's no good reccommendation in the ~40" monitor space with the pixel response being so bad on the 40 inch Phillips monitors and the numerous issues with the Dell 43" monitor and the discontinuation of the Sony X830C and Samsung 6300/6290 models.

I've been using an LG 43UF7600 for just shy of 2 years. It's not perfect, but in that time, the only other 40-43" I've known of, that I think I might've enjoyed more, was a 43" Crossover of some sort. I tried a Samsung, but MVA panels don't do it for me for text work.

If this new one is IPS, has a good anti-glare coating, has the same or better input lag, and does a more monitor like(as opposed to HDTV like) job with EDID and power saving, then I'll be first in line.

On some sites this one is described as 8-bit per channel monitor (16.7 million colors). If that`s the case... too bad.

Otherwise it is a UHD AH-IPS panel by LG with a matte coating, HDMI 2.0, DP 1.2, USB3.0 and USB-C.

This uses the same 43" panel as the Phillips BDM4350UW, the Dell p4317q, various korean brands etc.

It's a BGR panel and it appears to suffer from quite severe image retention.. Or perhaps LG has solved this? Who knows..

No, this is not the same panel used in Dell 43" and Philips BDM4350UC. Should not have image retention. But there is very little information at this point.

"Someone on OC.net said this was the same panel that was in the Crossover 430, but I don't know if that's true."

There are not many panels like this, so more than likely it`s true and in theory should be better than Crossover and with not that many dead pixels :) But there are other factors like backlight, signal processing, input lag, etc. I guess it will be more "game-oriented" at 60 Hz though and not very suitable for color critical work.

One more thing: the IPS glow on a 43 inch display will be very apparent and ugly.

I'm actually the person who replied to the thread on OC.net, I stumbled upon this forum whilst on my search looking for more information on this monitor, I doubt there would be much back-light issues with the new LG 43" monitor since it is using the same AH-IPS panel as my Crossover and there is virtually no bleed from the panel, maybe even an updated panel from LG themselves. However mine being a A- second grade panel, dead pixels were one of the issues I faced. There were slight ghosting on text when scrolling but other than that every thing was perfect.

Well, this sounds great, Hecadoth. I guess it`s a RGB, not BGR dot array.

So, is it a 10-bit or a 8-bit panel? Do you have any information about this?

Although I am not sure if you can get advantage from a 10-bit panel, if you don`t use nVidia Quadro or AMD FirePro video card.

I'm guessing it's a 10-bit panel since the AH-IPS panel they used for their televisions were the same, but then again it's just speculation not much information on the specs for now, what I can tell however comparing my crossover to the previous wasabi mango, there was a drastic change in the accuracy of colors, it could be due to be color calibration since the Wasabi Mango monitor wasn't calibrated only the crossover so I'm expecting good things coming out from the newest LG 43" panel! :)

Only time will tell. AH-IPS should have 100% sRGB coverage which is perfectly fine for color work. But it is a delicate and subjective matter, so no one can tell in advance.
Turns out Photoshop is using OpenGL buffers for the 10-bit functionality, so if you insist on having 10-bit per channel, you must have NV Quadro or AMD FirePro with display port output.

43UD79 will be available from the beginning of May, by the way.

Thanks for the info, I guess I'll have to wait to see the reviews and whether it has a good coverage of the Adobe RGB gamut.

Would go ahead and pull the trigger on this , but both sites listing it for preorder (Adorama and BH ) have TV/Monitor's this size as unreturnable if opened. Will have to wait for Amazon , as I won't be able to put up with any dead pixels and would swap until I got one without any.

I just bought a 50" 6300 series Samsung 4K TV 2 days ago for $449. Wonder if I should return it for this. I just visited this forum to read the guide on setting up a Samsung TV as a monitor and I see this gem.

And since I primarily use AMD video cards, I would utilize the FreeSync. Hmm.

I returned a 43" 7500 series Samsung recently because even with the curved screen the edges were color shifted due to the angle I viewed it at and the VA screen. Otherwise it was great, but the color shifting on the 3-4 inches on each side was too unpleasant. This being an IPS panel won't have the same issue.

This panel is only 60HZ though so I think Freesync won't matter unless you're gaming at 4K with high settings and can't maintain constant 60 FPS.

Actually Nvidia drivers (and in fact DX going back to ver 9 or 10) can render and output 10 bit color. In the Nvidia driver it's an output option most don't touch because they don't have 10 bit monitors. I do have one and it works well. HDR is also getting rapidly adopted and supported by DP 1.3+ So you are likely to see a large increase in 10 bit and HDR capable monitors going forward. TV/blu ray content as well as games will happily take advantage of the colorspace and contrast enhancement

Definitely need a review to see if these ones beat the philips, there's also another contender from viewsonic at 43"

This one is the best, on par with Wasabi Mango UHD430, Philips panel has image retention and is clearly lower quality. There is no clear statement as to the color depth yet, so according to more experienced people in the industry this is a 8-bit panel using frame rate control (dithering) - actually not the same as Wasabi Mango, which is marketed as 10-bit panel.

I saw a listing for a LG 43UD79T at Amazon recently. It looks to be the same panel as this monitor with a different stand design. Not sure if there are any other differences. Hopefully someone gets a review out of this panel and the new 43" Viewsonic soon.

Really looking forward to these display both the viewsonic and lg at 43" would really make a great monitor/pc experience on par with my current dell up3216q, but with a larger size, it really is a cool setup, I tried the Phillips 40 inch model and it was good except it had motion artifacts , that why I returned to dell flawless monitor, but I really miss the inmersion of a larger display, share any news on them please

LG now lists it on their US site.
Amazon now has both the 43UD79T (with a review) and 43UD79-B listed. I guess the T model is already shipping. It shows the B model ships in 1-3 weeks.
B&H says it expects to ship at the end of May.

A lot of press releases mentioned this having Freesync. LGs official page makes no mention of it so I'm guessing no Freesync after all.

Bummer because I would have bought one if it had it.

The advertised Freesync range was something like 54-59 Hz so I'm not sure it would even be useful.

Oh well, it's not like Nvidia supports the VESA standard of Adaptive-Sync anyway. Really annoying.

I read the USA LG page and there's a question there and it says in the answer that it supports FreeSync over Displayport. Also, the Amazon products linked above describe the T model as the Korean version. I am really getting excited about this monitor because I was about to pull the trigger on a couple Sony TVs soon, but this monitor would be a much cheaper option.

Fingers crossed on my part...

Rtings just reviewed two of the newest 2017 LG TV models which unfortunately use RGBW panels so they are not really good for PC use, but smokes, look at the input lag numbers. ~11ms, those are the absolute record numbers out of all 4k TVs ever made.

Bodes well for this monitor though, as we can probably expect similar numbers, perhaps even a bit lower.

I am using one now. The 43inch monitor is massive on my desk. I feel that it is too big for my usage. I wish they make it 40 inch instead of 43 inch. Moreover, it can save my neck if the panel can lower to the position so that it is just 1-2cm from the table. Otherwise, I am quite happy about it.

Hi,
Are you experiencing any 'image retention', 'ghosting', or 'backlight bleed' issues with your monitor? How about (any noticeable) 'input lag'?

I'm also curious if the audio selection can be 'fixed' to a specific HDMI / DP input? My Philips BDM4065UC monitor is very frustrating in that the Audio input switches every time the PIP is engaged or a new input is selected - there is no way to just 'lock' it to a specific input...

Thanks, -JT

Sorry. I just don't know how to evaluate the monitor in detail. For me, the image quality is just like the 27 Dell monitor's next to it.

It is sad that the 40+ inch monitor market is such a low priority to professional reviewers (and monitor manufacturers), because 40-45 inches is the most interesting size for 4K. I think when I say that in this thread, I'm preaching to the choir ;)

I am very interested in this LG monitor, but my last two 4K displays failed to meet expectations and I'm hesitant to do that a third time. My 2014 Samsung U28D590D taught me I can't tolerate input lag that most people can't even perceive. The 2015 Samsung 4K TV only reinforced that, as its lag in 4:4:4 mode feels twice as bad.
