Hi.. i would like your help on an issue i have with a new LG 4K monitor that i just bought... i connected Alpha R2 through HDMI 2.0 and recognized resolution just fine at 3840x2160@60hz but all of a sudden and randomly some blue square artifacts appear on screen horizontally... (picture attached)... i already updated all the drivers and windows updates without any luck.. Also the Alpha runs just fine in another monitor in 1080p.... any help please??
