HDR stuck
« on: January 05, 2018, 09:13:06 pm »
Found time to play with ripped HDR movies.

TV is LG E6 ... using RO ... MadVR set on HDR pass through

Under devices -> display modes ... restore original mode ... when media player leaves fullscreen

When playing HDR content ... tv goes to HDR mode (small HDR logo appears on TV) ... However, when stop playing movie ... and JRiver returns to Standard or Theatre View ... TV is still stuck in HDR ... everything looks over saturated ... have to exit jriver for HDR on TV to stop

What setting should I set so that when HDR movies stop ... TV returns to normal SDR

done some digging ... seems NVIDIA driver fault

rolling back my NVIDIA drivers to 385.69 as suggested in above forum
