I'm currently using a Q80R (firmware 1374) for PC gaming and I am noticing terrible inverse ghosting (panel overshoot) when in PC Mode. The color degradation is so bad that in some scenes the TV is unusable because it creates purple/green ghost artifacts whenever there is motion.
It is most noticeable in HDR mode. I have tried all different color modes:
YCbCr: 4:4:4 8-bit, 4:2:2 (8,10,12 bit) and 4:2:0 (8,10,12) bit and the issue persists.
When the TV is in regular movie mode, the issue is not present, which leads me to believe that the panel overdrive setting is too aggressive.
Previous firmware updates have claimed to addressing ghosting issues, but nothing seems to have changed on my panel.
Any help would be appreciated. Thanks!
