whenever I try to play an UHD MKV HEVC file with 10 Bit colors on my non HDR Samsung TV HU8590, the picture is way too dark (latest Infuse version). The same movie encoded with AVC 1080p 8 Bit color space works fine.
Is this a problem of my TV or do I need to set something else?
ATV 4k settings: 4k SDR, auto frame rate on, YCbCr
TV makers make no sense. Why would you disable High color, deep color or UHD color support by default for a 4K TV ? For example, Sony enables it by default on the side (secondary) inputs, but disables it on the inputs at the back, which also support ARC (so where your receiver/amplifier is supposed to go).
