I just checked with the leo bodnar and changing device type to game doesnt do anything. Pc mode is 36ms when uhd is off, when you turn it on it goes up to 44ms, so turning on 4:4:4 raises the lag in pc mode. Again use dvi/pc as device type for lowest lag and 4:4:4. I also tried all of the hdmi inputs, all turned back the exact same numbers. As for the 1209 update, I still dont feel the chroma test brown fox looks that great, compared to pc mode for 4:4:4. Text is readable but not great on that test, some letters like N's got better but others got a little worse. Still hoping Samsung updates game mode to have 4:4:4 and the input lag doesnt increase by doing it. I also checked and pc games are passing 4:4:4, I can clearly see this in pc mode with certain colors like blue and red, red being the most apparent.
