i have detected a small latency and occasional trouble with sdi feed sometimes unlocked which means picture sits on screen in 2 parts with bar in middle, turning off and on fixes this, but to date it is my favorite monitor , i have the battery back for vlock more for the feel , the added weight is good for my steadicam,i love it and have become very comfortable with the menu functions, as per usual have 100 settings and use 6 but it is very cool for steadicam , reverse scan , level, luts, sharp , bright, good mounting points,i have a second one i use on location with a bolt sender, the joy of a steadicam op these days where video senders work and bright monitors are in color not green.
