What size screen do you use
At what distance will you be placing your monitor? If you have a small desk and want to place your monitor an arm’s length away, 24 – 27" might be just fine. Large desk with the monitor a couple feet back — 32 – 36" may be more appropriate.
Ultimately, you want to be able to comfortably see the screen with minimal eye movement. Very large screens seem immersive at first, but if you’re having to do a lot of eye and head movement to see everything from one edge to the other then you’re going to get fatigued a lot faster.
