zapatista is exactly right. I have a 55" Samsung monitor (
http://www.samsung.com/hk_en/consume...ype=prd_detail). I sit about 30"-36" away, which approximates a 80 degree FOV as shown in the following formula:
HOW TO DETERMINE THE CORRECT DISTANCE FROM WHICH TO VIEW THE SCREEN IN ORDER TO SEE A 1:1 REAL-WORLD IMAGE SCALE.
view dist. = (scrn width/2) / TAN(FOV/2)
Example:
Screen width = 50" (the measured
horizontal display size)
FOV = 80 deg.
view dist. = (50"/2) / TAN(80/2)
view dist. = 25 / TAN(40)
view dist. = 25 / 0.839
view dist. = 29.8"
At this setting objects are their real-life sizes, there is never a need to zoom in or out. Its certainly easier to spot enemy a/c, and there is never a need for icons etc. Its very immersive.
