I do the same, set it in windows to turn the display off after 3 minutes of activity.@Darren1967 Honestly I'd just set windows to turn of display after like 1-2min, also I wouldn't worry about leaving something on screen for couple minutes, I mean on my CX I played WoW everyday on it for months doing M+, so for most part everyday for couple hours or so it'd have mostly static UI on screen and never had a issue
