I'm having a lot of trouble configuring my new M9201 connected to my LG B8 OLED. HDR/DV is not engaging and video in general has gamma issues with heavily crushed blacks. Also, I'm not getting any audio, regardless of which setting I use. I'm just trying to do audio output via HDMI to my TV speakers. I tested my Shield via the M9201's HDMI-in port and it's exhibiting the same gamma issues and overscanning as well, cutting off the edges of the picture, even set to passthrough.
I'm just trying to play files from HDD connected via USB to start before getting into streaming over SMB from server. The files I'm testing with are DV profile 7 remuxes in MP4 container with AC3 5.1 audio, which all play just fine with my TV's native media player.
Can anyone suggest the proper settings to use with my TV?
