Having owned the CX and a good 38" IPS, I see a lot of idiotic fan boyism on this forum. Yes the CX is great for a lot of things but for comfort working and viewing angles the IPS is still king. And no the move it further back comment is equally idiotic because you have to constantly finess scaling options and even at 4" feet distance, it requires too much vertical neck movement to use the whole screen.
A curved 40-42" OLED will be perfect though since the size and viewing angle issues will be largely mitigated. Curved TVs make no sense but curved monitors make total sense.Peace out.
I picked up a CX 55 today and set it up for PC use.
To those who have an OLED for PC monitor...what kind of settings are using to minimize the potential for any kind of burn in? I had a Samsung LED before this so never did anything besides make the screen go off after 15 minutes, so input is welcome on how to make the most of this thing.
Just don't unplug it from the wall socket and you will never have any permanent burn-in. Use it like a normal monitor how you like it and don't bother with burn-in. Even if you see the burn-in it will disappear. Just learn not to pay attention.I picked up a CX 55 today and set it up for PC use.

Use it in a dark room with lowest OLED light that is comfortable to you (talking SDR here, HDR is more complicated and I'm frankly not bothering with it too much, I'll wait for better software and hardware support). Note that you need to give your eyes a bit of time to adjust before assessing whether brightness is high enough or not.
Optional: dark mode when possible within the apps, auto hide taskbar, black desktop background with no icons, black screensaver.
I set my background to a 10 minute slideshow to change background images. Does that sound fine?
As long as there are enough images in the rotation, I would think so. Remember the moving wallpapers that Vista had? OLEDs would be a great use case for those. Personally I just use a black wallpaper because where I don't run browsers etc. full screen, it looks great since anything outside of my active window is pitch black (not glowy black like it is with LCDs).
I really think it's overblown though; I daily'd my B7 as a monitor for years and never developed any burn-in. I think the biggest thing is keeping your OLED light as low as is comfortable and varying the content from time to time.

Right now I have 4 photos on a 10 minute rotation. and I minimized task bar, removed all desktop icons, and running dark mode.
It's fine, it'll still wear down the panel a bit, but evenly so it's not an issue. The burn-in that bothers people is just 'uneven' aging, i.e. when one small of the screen gets abused way more than the rest. OLED components have a limited life, so if you have for example a bright static logo in one part of the screen for a really long time it will become harder and harder for the TV to compensate the uneven wear of the panel. It's a slow process with recent OLED TVs.
Oh and the part about never unplugging the TV is true. When you turn it off with the remote it will occasionally do stuff in the background to combat burn-in.
RTINGS has done a long term burn in test with multiple OLEDs displaying different content. The gist of it is that OLED burn in is cumulative and will occur after thousands of hours of displaying the same content has been racked up. So even without much precautions taken, it would take quite a while for you to get any burn in. If you are varying content consistently then the amount of cumulative hours it would take for you to get burn in will be so long that you probably will have bought another display by then. My oldest OLED is 4 years old (2016 B6) and to this day still has no signs of any burn in.
I will say the one thing I can see is, I have the taskbar minimized and I can still see the very TOP line of the "search bar" at the bottom of my screen. Is that going to be a problem?
Yes, after a very long time it can be (a very long time). There is a program that's been mentioned in this thread that can hide that last bit. I don't recall the name offhand.I will say the one thing I can see is, I have the taskbar minimized and I can still see the very TOP line of the "search bar" at the bottom of my screen.

What floor stand are you using? And can you show a picture of your setup if you don't mind?Yup that is why I bought a floor stand for the LG 48CX instead of trying to fit it on a desk (wall mount is cool too, but I don't own this current apartment). Sure it's possible to make it work on some desks but from pictures and videos I've seen, a lot of people clearly do not have the right desk for that. There is a gap now between my desk and the TV but who cares? Heck, it's probably beneficial cooling wise during the heatwave we're having here lol

^ Really, the best thing for OLED longevity is don't even turn it on. Why risk it? Mine's staying in the box.

OLED is really not that fragile. You just need to keep it connected to the power socket and that's all. For all the years I never hid the taskbar or desktop icons, never run any type of screensavers of any sort, left it on for 10+ hours... and never run into permanent burn in. The burn in you get from windows or icons goes away as soon as you turn it off with the remote and let the display conduct its pixel refresh routine or watch some youtube videos for 5-10 minutes in full screen. Just use it as a normal PC monitor and forget about burn-in. And don't cut the power to the display.
So what is current status on raised black levels when using Windows 10 HDR + VRR (Gsync)? SDR with Gsync seems perfect.
Windows 10 HDR with Gsync off also causes raised blacks just by itself but HDR + Gsync is significantly worse. I cannot notice any difference between SDR with or without Gsync enabled in black levels.Ah so SDR with VRR looks perfect? Thanks for backing me up on this because someone on AVSForums was making claims that VRR also effects SDR black levels. I tested VRR with SDR and everything looks perfectly fine. I actually haven't really tested HDR with VRR so maybe that's where it happens.
Windows 10 HDR with Gsync off also causes raised blacks just by itself but HDR + Gsync is significantly worse. I cannot notice any difference between SDR with or without Gsync enabled in black levels.
I've noticed that the black sidebar in LG's menu remains perfectly black in Game HDR mode, so the raised blacks is definitely an issue with just Windows and/or nVidia. I wish I had an AMD GPU to help narrow the issue down between nVidia's drivers, Gsync/VRR vs FreeSync, LG firmware, or Windows 10.
Currently using a CX 55, but I am using a floor stand as well.

I am using this floor stand and I really like it. I did have to lower it more, though. There are 4 screws and 6 holes to secure the height. I am only using 2 of the lowest screws. But other than that, it is great.What floor stand are you using? And can you show a picture of your setup if you don't mind?
Hey, I wanted you to know, I posted over on AVSForum a solution to raised blacks with HDR. I could correct it by either setting the Black Level to Low or keeping Black Level at Auto but lowering the brightness to 46 (VRR On).I see. I've been using my CX at 4k 120Hz 420 so I cannot even enable HDR due to bandwidth restrictions until I get an HDMI 2.1 GPU. At 4k120Hz SDR + Gsync there has been zero raised black levels. I wouldn't be surprised if HDR was the cause.

I'm certainly no expert either and I don't know which solution is preferable: changing black level or just lowering the brightness. I haven't noticed any image problems in my commonly used apps/games by using Black Level Low in HDR mode, although it does negatively impact image in SDR mode.I'm not an expert on how HDR signals are encoded at the RGB level...but setting the black level to low when it shouldn't be would prevent raised blacks....by raising everything even more. If you send a limited range RGB signal to a TV, it's going to send 16-16-16 as black, and your TV with the black level set to low will consider 0-0-0 as black and display the signal as grey.
Thanks, I appreciate your input. It's difficult to read through the AVS Forum thread, especially since there isn't a search option for the massive thread. My main goal was to get rid of the washed out black background I use on Windows 10 when HDR +/- VRR is enabled. I think just lowering the Brightness as was suggested over there is best option. It was suggested lowering to 49 by multiple people, but I had to lower it down to 46 to completely get rid of the washed out appearance. Using Black Level Low accomplished the same effect but has a much more deleterious effect in SDR mode than in HDR mode.From what I read over at avsforum, the raised blacks when VRR is active are because the near-black fix is being bypassed. Near blacks had been flashing on C9's so LG released a firmware for dithering them but apparently it resulted in some lost detail in so LG changed the near-black fix to flattening of blacks. Again, from what I read, the near black fix is bypassed when VRR is active. That means the grey-blacks would be around high contrasted edges in near blacks. If it's localized like that then adjusting the whole screen darker really isn't a valid "fix" since it would darken the rest of the screen too. I mean, it might be a choice between two evils ~pick your poison if that were the case but I wouldn't call it a real fix. Assuming all of that is true, what was posted on avs forum and what Vincent at HDTVtest has said in reviews .. LG could still address it in a future firmware fix potentially.
If I go this route, I would have two monitors with the taskbar, icons etc. on the 2nd monitor and keep the TV free from fixed position stuff or long term items. Wall mount too which would free up the desk and also make it more clean looking as well.Getting mine wall mounted next week. Biggest complaint about it on my desktop is there's really no way to route cords around it from keyboard etc. But I removed all icons, taskbar hidden, slideshow desktop background change every 10 min. It's a dream.
