Agreed - get an Ultra HDMI Certified cable that‘s rated for 48Gbps, 4K @ 120hz. I picked this one up off of Amazon for ~$12 and it is working great.
This is very very likely the cable, try a different one. 4k120/10bit/Gsync needs power and quality on the cable.

I got the 10 feet blue one today. When I play overwatch in windowed full screen or full screen with Gsync the screen flickers to a gray/pixelated image for a second before returning to normal. Happened multiple times. I turned gsync off and it didn't happen once.

With the other cable it used to sometimes freak out at just a normal desktop (no hdr) at 120hz, this cable solved that issue at least.

Other thing I noticed about this screen is that the color shift is pretty big. Even if you're looking at it directly from the middle, you can still see it. Most noticable with gray / white colors (pretty noticable here).

edit: I've got an MSI Ventus GeForce RTX 3080 10GB framerates seemed to be locked to 118 w/ windowed fullscreen and 130 fullscreen (not sure why that happens, i set it in-game to Match Display)

Looks like you still got a faulty cable, try another one (seriously).

My brother for example needed five attempts to get finally one that worked flawlessly.

Long HDMI cables can be notoriously difficult to get working right. I also had to go through about 5 for 8-10 m cables and this was just for 4K 60 Hz many years back.

I have this Zeskit Maya 8K 48Gbps Certified Ultra High Speed HDMI Cable 6.5ft, 4K120 8K60 144Hz $12.99 cable on 3 of my oled and I have RUIPRO 8K Fiber Optic HDMI Cable 10 Feet 48Gbps 8K60Hz 4K120Hz Dynamic HDR eARC HDCP2.2/2.3 on my main oled that's costed $94.99. Works exactly the same , go for the quality 12.99 cable if you can.

You must present evidence they perform as suggested.
I can connect almost any HDMI cable to my satellite box and watch TV. It doesnt mean the cable can do the speed its rated for.
Say what you tested and found to work.

there only 2 things I must do in life. be born and die the rest is choice. both cables do the speed they're rated for as I only game 120hz on my 3080ti's and been gaming with these cables for over a year. i have 3 LG 65 CX and the C2 , so believe me if you wanna trust anyone about cables it be me , since have alot of setups all using the cables and just not one setup.

I didnt doubt you could back up your claim but sometimes people are here to push a product.
Its useful when your experience is expressed fully and calling it out helps deter those who ruin threads for their own gain.

I get you, you are right on that. The Zeskit Maya 8K 48Gbps has been getting many reviews for a long long time now, but being curious i wanted to try RUIPRO 8K Fiber Optic HDMI Cable which also works great but i think is more of a design you used if you wanted to go further than 6ft of copper when hdmi could lose signal integrity. but there are alot of bogus cables ou there you are right Nenu and some people claim they work, and it could be luck also. But i got some serious ocd lol and would recommend these two cable I use. Have a great one

Nope. OLEDs aren't designed to display static images at high brightness. That's a fact, and the worst-case use scenario for OLED panels. https://www.zdnet.com/article/lg-switches-airport-oled-to-lcd-amid-burn-in-row/

Sure, use it as you see fit. But abuse it at your own peril. These are probably not the best choice for someone who is going to have static window positions all day, every day. Simple as that. I'm not sure why my post offended you. I never called anyone stupid, I just said don't use them in a stupid manner that exploits the one thing they aren't designed for.
It did not offend me, I actually enjoyed it. I thank you for rising to the bait and being a classy human.
You at least have a sense of humor; I would call it an ignorant manner or using it inefficiently, and if I keep doing it then by all means stupidity reigns, or insanity, either way maybe a Darwin award deservedly so. I always find it is a quick way to admire and respect another human, sometimes it might bite but always worth it one way or another.
All my best to you and yours.

PS. we can always say I was trying to protect your future political aspirations. By beeing more sensitive, LOL
You enjoy life and its pleasures.

Since the C2 is a "smart TV", it appears that someone has also figured out a way to power an LG OLED TV on or off (so long as it is connected to a network) via the PC.
Nice option if you don't want to have to always resort to using the remote:

https://github.com/JPersson77/LGTVCompanion

"reponse to to the PC shutting down, rebooting, entering low power modes as well as and when user is afk (idle)."

Awesome find thanks

Fucking finally
42c2.png

The white uniformity is actually very good compared to the old C7. Haven't experienced the full 4k 120hz yet, it turns out my HDMI Audioquest Forest cable from 2013 supports only 4K 10bit 60hz gsync max, but I played some Battlefield at 1080p 120hz with Gsync never the less and i can say that the monitor is quite responsive, not as addictively blistering fast responsive as the Predator X38 but is responsive enough to not suck in FPS gaming or feel as if it's a job. With Predator, owning people was plein easy, with 42C2, you might have to try a little bit harder. Maybe the native 4k 120hz will be more responsive, though even as it is now in 1080p 120hz it is quick enough, hands down.
Most importantly and what had bothered me the most was the problem with the white uniformity, and it turns out it was greatly exaggerated. It is present, but it could be much worse, given how the LG C7 looks.
Yeah, and 42" display is still huge for a desktop monitor. At the same time, compared to the 55" it is a definite upgrade in terms of comfort.

With the higher ppi does the C2 42 have better IQ for games than larger LG Oleds? My new C2 42 is amazing looking in pc games and I'm thinking about buying a C2 55 or any LG Oled that's 55" or larger so I can try to answer that question for myself. But if anyone else can venture a reply to it in the meantime. And sorry if the question has been gone over a lot already.

I don't think it matters to movies because I believe the consensus is few people can tell much of any difference in regards to the question as applied to movies/videos. So the question is still just for games.

The answer is "it depends".
On how close you are sitting to the screen.
On how sensitive you are to pixel size.
On how often you are using the monitor outside of gaming.

42" 4K is great because it has a somewhat standard pixel pitch for a desktop monitor.
48" is kinda okay too as it's the same as 32" 2560x1440 for example.
Anything larger though will result in pixels being rather visible in a typical desktop monitor setup distance.

I've been keeping tabs on this thread as I may eventually get a 42" OLED. I did pick up a Samsung QN90B 43" to use with my AMD 6900XT. This cable from Amazon is the only one over 25ft that I was able to get working: AAXY 8K 40' HDMI

Verified that it will do 4K @ 120/144Hz 10bit 4:4:4.

I bought this at the end of December as I was having issues with the previous cable just doing 4K @ 60Hz, but unfortunately it is showing as unavailable currently.

Larger size doesnt matter if you can place the display further away.
Longer focal distance is a great way to relax the eyes too.

Thanks. 8k may be a solution for boosting ppi on a 65"-75" screen meaning a single 4090 video card may be able to handle it ok. I may be veering off the subject though.

At which point there is no benefit to buying a larger size, yeah.
There very much is but you chose to disregard it.

Depends on what is your typical sitting distance to start with.
It only depends where you can place the display and what is comfortable.

Hope you didn’t drop a ton of cash on that audioquest cable. Don’t they make like $10,000 cables?
HDMI Audioquest Forest cables cost around $100, depending on length - these are entry level cables. Unless you want a 5m cable, which may cost $300.
Also, it seems like the old Forest cable does support 4k 120hz, I just didn't know I had to scroll down the resolution list in the nvidia control panel to select the 120hz option. Well, too late because I already bought a new 3m Forest 48g HDMI cable 😁 I run my DAC off the TV's optical out, so it's important to me to have a high quality HDMI cable 🙂 It wouldn't matter that much if it was only for video.

I think that the IQ is undoubtfully better. Sharper, clearer.

so many of you using this monitor hides your windows task bar? And if you don't hide it, do you have any burn-in so far?

I don't hide the task bar, I just checked there is no burn-in after several days of use.
Note, that temporary burn in appears fast on this display, several minutes is enough for the image to burn-in in form of dark clouding on the display, then it disappears after the monitor is turned off, or the image is no longer displayed. If it stays for too long and doesn't go away by itself, Pixel Cleaner is the solution. But as I said, the taskbar hasn't burnt in, and I never disable it.

I'm about to pull the trigger on a 42" C2 after swearing never to buy another OLED (I ruined my first). I'll be consulting this thread often to make sure I don't ruin this one.

It is a preventive measure as an added precaution so please stop being obtuse. Do you wear a seatbelt when you drive?
So he's being obtuse my asking for feedback on those that don't hide the Taskbar? OK. Sounds like a legitimate question to me.

I often see people conflating image retention and burn in when they really have nothing to do with each other. Even Vincent Teoh (HDTVTest) is guilty of this, and he should know better.

Image retention is caused by charge build up in the cells. LCD, OLED, and plasma displays are all susceptible to this. It's not permanent, and typically goes away after a short time once the image changes. Image retention is not in any way an indicator of a panel's propensity to burn in.

Burn in, as it applies to OLED, is caused by gradual dimming of the individual OLED emitters with use. Think of it like a light bulb that slowly dims over its life time. If some pixels are run consistently brighter over prolonged periods (e.g. when there's a logo always on the screen) those pixels dim sooner than the surrounding pixels, resulting in what we call burn in. It is an irreversible physical process. However, LG OLED TVs use a method that masks burn in by monitoring the usage of each individual emitter and periodically adjusts the voltage levels to match the brightness of the most worn out emitters. So instead of seeing burn in (which is differential dimming), the entire panel gets dimmer than it otherwise would over time. This process keeps the panel looking uniform for much longer, but if some emitters continue to be run harder (by always displaying the same logos) burn in will eventually still become visible. This should take many thousands of hours of static logos, however, and taking a few precautions will significantly prolong the lifetime.

The bottom line is that burn in is a process that will only become apparent after years, not days or weeks. Some people may never see burn in at all if they rarely have static logos/content displayed, as the life of the emitters may outlast the panel's other electronics or its useful lifespan.

OK, maybe not so much obtuse, more the chicken little "sky is falling" gas lighting vibe then. Go back through the entire thread and read all of his posts. Just sort of fed up with folks that don't own OLED panels parroting/trolling the same overblown FUD.

I've owned an LG OLED panel which I game on regularly for over 3 years now. Zero burn in - and many games have HUDs and fixed elements that are up for several hours at a time. If you use the new C2 as a monitor, there are simply not going to be any burn in issues using it as long as you don't go doing something really stupid with it - like leave it on 24/7 with a static image set to max brightness for a few months. Own a car? Well, it is NOT a good idea to go driving it at redline for several hours a day. Could you? Sure! Consequences? Very likely.

It's perfectly ok to take some precautions to limit said risks, some do, some don't, but yapping about it continually as if it there was some sort of real, systemic problem here concerning burn in really is getting old. There's a ton of tech built into these panels to prevent/minimize possible burn in, and normal use simply isn't going to have it manifest. Still worried? Still have doubts? Then simply DO NOT BUY ONE. I'll keep enjoying mine. Best damn monitor I have ever owned.

No idea what JScreen Fix is. Pixel Cleaner though:
pixel cleaner .png

I run it once to clear the dark clouding caused by the desktop icons that were burnt in in such form. Or image retained or whatever... So, having icons on your desktop is outta question with the 42c2. For me at least.
The clouding would probably dissolve by itself, since the task bar was never hid and it shows no sign of burn-in, but I guess I didn't want to wait. After the procedure - the screen became white as an A4 sheet of paper.

This option age all pixels to the level of the "oldest" present. Thus you're basically dimming the whole panel to the level of the dimmest (burned out) pixel. Not a very good solution IMO.

I haven't noticed any dimming. The screen is bright as fuck. It got to be much less bright if it matched the dark spots.

Another voice from the choir heard from. I am amused, Lat used an incorrect word, I would prefer ignorantly instead of stupidly, because I think when someone pays for something It is theirs to do as they wish. No way do I have the right to tell them how and when to use something. If they ask I can offer advice, If I pay for it unless its' a gift, by all means I decide.
It seems like Bidet, some folks must do as they are told by those little voices in their head and decide what others are worth. I disagreed with Lat's choice of words when offering his decent advice. If he does not complain why do others, but that is todays humanity.
Regardless he has way more class than some of the so called humans in this place. I figured he would not mind someone busting his chops, apparently others do.
I have no idea what you were taught but when I went around calling folks stupid or telling them they were acting stupidly more than likely it would lead to a nasty conversation or fight. But then again the US has become a nation of putties.
On the net it's amazing how many folks butt in when they are not the topic of conversation.

You don't. It is done automatically after x hours of cumulative use on the LG OLEDs when the display is turned OFF as long as it's connected to power. It is invisible to the user. While you can run it manually, I haven't done so during the two years owning the LG CX 48" and using it as a desktop display for work and personal use. No burn in.

There is no point running it manually basically. If you notice an uniformity issue that you are certain wasn't there before, then you can try to force it, and it may help. But most people shouldn't worry about it.

Saying you are dimming the panel every time it runs is not wrong but those panels leave factory with ample brightness headroom. Which means that, instead of dimming the whole panel, they can keep pumping more voltage into the dimmer pixels for a long time - and thus you don't see any dimming (until you do, of course but talking years of heavy use here). There is ample evidence of this with tests such as the ones done by Rtings.
