Nope. I'm using an OLED TV as a monitor on my main PC, and it kicks the pants off any monitor I've ever used before, including the 2021 MBP monitor I'm typing this on right now.
LG C1. I have to turn it off and on with a remote, take the usual OLED precautions, and tolerate its "smart" nonsense, but the color is gorgeous and the contrast is magical.
I boot into Windows for gaming and when I launch a full screen game an "AutoHDR" badge pops up and the brightness limit is lifted. A similar thing happens when I launch a streaming app in the TV. I don't consume content through Linux because as far as I can tell linux doesn't support HDR yet.
Speaking of booting into Windows, I finally figured out how to make it painless: use a separate hard drive, not a separate partition. I wish I could go back in time 20 years and tell myself that. The number of hours I wasted debugging poorly written installers, bootloaders, and updaters exceeds the cost of hard drives by a factor too terrifying to calculate. Ah well. Now I know.
Any worries of “burn in”? I read the risk of using one as a monitor is that with a computer there is often static images like your task bar. Those can burn into the screen permanently where as if it is just tv the image often changes. Shows like news often have a bar at the bottom and was warned those too can cause burn in. Curious what your experience has been? Thanks
Yes, OLED care is a concern, and I take the usual precautions: no fixed menubars, no tiling WM, rotating desktop wallpapers, and reduced brightness (which isn't a compromise -- anything above 80% makes light-mode content uncomfortable, and auto HDR raises the limit for actual HDR content).
Even if I were not taking these steps and generally abusing the monitor, I wouldn't expect to see burn-in yet, so I can't really speak to how the situation will develop.
