@RustyCrab @zero ips LCD panels are not that good for competitive type gaming. Amazing color and viewing angles, and usually better contrast too in my experience. Just bad latency. You notice it less if it is high refresh rate. TN is superior latency, VA is a good mix of both. IPS panels are about to get a lot better because of Nvidia's upcoming Pulsar tech.
OLED is superior in pretty much every way to all of these except for the VRR flickering. Burn in is a non issue now really.
You've probably done this already but make sure your monitor is set to use full dynamic range (0-255) instead of limited (16-235). Might help with your black levels there. Also, disable hdr in games because there is a pretty high likelihood your monitor doesn't have great hdr support and it'll just leave the image looking super washed out.
@zero @RustyCrab I guess if people are making shitty oled screens but like, a YouTuber did a test where he left breath of the wild on a switch oled and it took thousands of hours before it became an issue: https://youtu.be/Po8jAQjvd88
If you use some sort of screen saver, hide your taskbar (or even use a transparent one with an animated wallpaper or something), you'll probably be fine for a while. Burn in WILL happen but like, not in a very meaningful way and not awfully quickly. I don't think it is necessarily something you need to worry too much about.
