Reposting my answer from a similar thread. TLDR: I took the plunge on OLED TV in 2021 as a primary monitor and it’s been incredible

I’ve been using an LG C1 48" OLED TV as my sole monitor for my full-time job, my photography, and gaming since the start of 2021. I think it’s at around 3000 4500 hours of screen time. It averages over 10 hours of on time per weekday

It typically stays around 40 brightness because that’s all I need, being fairly close to my face the size. All of the burn-in protection features are on (auto dimming , burn-in protection, pixel rotation) but I have Windows set to never sleep for work reasons.

Burn in has not been a thing. Sometimes, I leave it on with a spreadsheet open or a photo being edited overnight because I’m dumb. High brightness and high contrast areas might leave a spot visible in certain greys but by then, the TV will ask me to “refresh pixels” and it’ll be gone when I next turn the TV on. The task bar has not burned in.

Experience for work, reading, dev: 8/10

Pros: screen real estate. One 48" monitor is roughly four 1080p 22" monitors tiled.The ergonomics are great. Text readability is very good especially in dark mode.

cons: sharing my full screen is annoying to others because it’s so big. Video camera has to be placed a bit higher than ideal so I’m at a slightly too high angle for video conferences.

This is categorically a better working monitor than my previous cheap dual 4k setup but text sharpness is not as good as a high end LCD with retina-like density because 1) the density and 2) the subpixel configuration on OLED is not as good for text rendering. This has never been an issue for my working life.

Experience with photo and video editing: 10/10

Outside of dedicated professional monitors which are extremely expensive, there is no better option for color reproduction and contrast. From what I’ve seen in the consumer sector, maybe Apple monitors are at this level but the price is 4 or 5x.

Gaming: 10/10

2160p120hz HDR with 3ms lag, perfect contrast and extremely good color reproduction.

FPSs feel really good. Anything dark/horror pops A lot of real estate for RTSs Maybe flight sim would have benefited from dusk monitor setup?

I’ve never had anything but a good gaming experience. I did have a 144hz monitor before and going to 120 IS marginally noticable for me but I don’t think it’s detrimental at the level I play (suck)

Reviewers had mentioned that it’s good for consoles too though I never bothered

Movies and TV: 10/10 4K HDR is better than theaters’ picture quality in a dark room. Everything I’ve thrown on it has been great.

Final notes/recommendations This is my third LG OLED and I’ve seen the picture quality dramatically increase over the years. Burn-in used to be a real issue and grays were trashed on my first OLED after about 1000 hours.

Unfortunately, I have to turn the TV on from the remote every time. It does automatically turn off from no signal after the computers screen sleep timer, which is a good feature. There are open source programs which get around this.

This TV has never been connected to the Internet… I’ve learned my lesson with previous LG TVs. They spy, they get ads, they have horrendous privacy policies, and they have updates which kill performance or features… Just don’t. Get a streaming box.

You need space for it, width and depth wise. The price is high (around 1k USD on sale) but not compared with gaming monitors and especially compared with 2 gaming monitors.

Pixel rotation is noticeable when the entire screen shifts over a pixel two. It also will mess with you if you have reference pixels at the edge of the screen. This can be turned off.

Burn in protection is also noticable on mostly static images. I wiggle my window if it gets in my way. This can also be turned off.

This may be controversial, and may also be totally wrong (I’m no display expert), but I have a 55” Hisense U8K QLED and am still legitimately shocked at how black the blacks are. I can’t even tell if the screen is on or off if it’s just showing my black background. No light bleed or blooming, and inky rich blacks with incredibly smooth gradients. This screen convinced me that I’ll never need to shell out for an OLED.

Edit: in case you’re curious, I use it as the third screen in my PC setup, running at 144hz. It’s also my first experience with high refresh rates, and it has been a joy. Oh and the nits on this thing are something else. Ever been blinded by a sunrise in 4K HDR? It’s awesome.

Lg oled. Looks amazing. Will never go back to normal lcd. BUT some games will result in but in. Eg vampire survivors has left a perm red affected burn-in from its health bar placement in the middle of the screen. So be wary.

I have a Mini-LED HDR monitor (Acer XV275K P3) and it looks great. It gets super bright with black blacks. I didn’t want to risk burn-in, it covers the full 1000 nits that most HDR content expects, and it was only $550 which was quite a steal. There’s occasionally a little blooming in dark scenes in movies, but in games it never gets that dark and there’s mostly very bright things instead.

I have HDR working on Plasma 6 with an AMD gpu on NixOS, although recently Gamescope/Steam has been a bit bugged. MPV still plays movies perfectly though. I even set up inverse tone mapping so SDR videos get converted into HDR, which looks a bit better than normal SDR imo.

I have an Alienware AW3423DWF since about a year now with about 4000 hours on it. Very happy with it, won’t be going back to anything else until another technology with per-pixel lighting comes along. I also have a Dell with VA panel as second monitor and it looks like 90s technology compared to the OLED panel.

The only bad thing I can say about the monitor or OLED in general is that the dimming is fairly aggressive, i.e. on bright scenes you will not even get close to the advertised brightness. Makes the OLED monitors pretty much unusable in HDR for desktop usage. Mostly unnoticable in gaming and movies.

There also is some text fuzzing with high contrast text, not distracting for me but might be for others.

but how is the current compatability with Linux these days?

No issues here on Linux. With Plasma 6 you can even do HDR properly. Many games work with the latest Proton-TKG on Wayland and the HDR layer, some still need gamescope to properly work. mpv does movies/shows in HDR with the HDR layer, no issues.
