Thought I'd share a quick setup video (for games/sims) for my recent addition of a Samsung 8500 series 4K UHD TV/Monitor. I was somewhat surprised the Samsung didn't configure itself for the best possible mode for PC operation by default (out of the box) and buried away the most critical settings in their menu system. I know many are having issues with 'lag' at 30Hz refresh, but after using my Sony XBR 4K, LG 4K, and now this Samsung 4K (all at varying price ranges), they all were able to operate at 30Hz or 60Hz without any 'visual' issues and with excellent image quality. I also cover some of the Samsung HDMI "Black" options that can make a significant difference, especially for night flying.
Due to how the Samsung onscreen settings work, I had to record some of this video externally with my 4K camera (at night so color is not representative of actual image) as the OSD settings wouldn't capture to my Magewell video capture card since those overlays are generated by the TV/Monitor itself.
Cheers, Rob.
