I've been using an OLED monitor for 2656 hours, and I'm not scared of burn-in: Here's why

Burn is only inevitable with current technology. Next gen panels that use phosphorescent dyes, TANDEM design, possibly 3D printed will have much lower energy use, much longer lifetime dyes, and should be a massive improvement. I'm in no hurry and am looking at 2027 for next gen 5Kx2K 40" monitors. For now IPS black or mini-led is a much, much safer bet and still has excellent black levels, high enough refresh rates for 4K gaming, and will last a decade or more.
 
I have a LG 65C9 tv with over 4000 hours and no burn in, I also have a 39GS9 monitor that just passed a 1000 hours but I just switched back to using my tv as a monitor and don't want to do back.
