Appreciate the detailed insights.
I was about to ask about your viewing distance, field of view and visual acuity.
Are you using 4K resolution at 100% or Scaling Windows to 150%?
Any additional computing / user experience/ productivity thoughts?
I am considering getting a 4K TV for Productivity - 40 to 50 to 55" - not sure of OLED, but hopefully IPS maybe VA with Croma 4:4:4 at 60Hz atleast.
4K @ 125% at 4.5 feet from screen. Wall mount is best for PC usage as I am able to tilt it downwards for better viewing angle towards the top which is the farthest from eyes. If your space allows it may be better to align your eye to 70% of the height of the monitor. This will allow a more comfortable viewing experience. In my setup my eyes are at 50% of the height and looking at top of the screen continuously is difficult
