Hisense 55H8C - HDR looks terrible?
I just got a 55H8C. It looks great when YouTube plays 4K. However, the only way I can get the display to say "4K HDR" is to change the "HDMI Function - Format" setting to "Enhanced". And when I do that, the picture looks very bad. It's dark with muted colors. Again, when I make the HDMI Function Format to Standard, the picture looks great, but the YouTube display doesn't say "HDR" - it only says "4K". Can someone explain this?
