Artifacts, weird colors and generally horrible picture when playing 4K material on samsung 2017

I have trouble streaming 4K material using Plex on my MU7005 (MU8000 in the US). Do I need to do anything with the profile or is this a general problem with these TVs?

Mediainfo (MKV container):

Dear Lord. If we give you Lady Gaga and Nicki Minaj, would you consider sending us back Dimebag Darrell?

    what's your setup and connectivity between TV and media server?

    I've seen this on some recent releases.

    Crazy fast overpowered pc and gig LAN. The problem is either in the files or the TVs / Apps filesupport, not the setup. Some files work, some dont. Its hit or miss really.

    You are right! Thank you so much! Everything with AC3 seems to play fine (Direct Plays), anything else(?) gets Direct streamed and with a horrible, artifact filled image.

    Thank you so much for figuring this out for me!

    Hi, I am having the same problem as RockStar. @DanJD can you check the link for your post is the right one? It's going to TRUEHD Passthrough issue, not how to get Plex to stop transcoding.

    Sorry for the basic question, but should I be looking for entries like the following to see if transcoding is taking place?

    [Transcoder] Video (decision) options
    INFO - [ui-safari-tizen] hasMDE: 1
    INFO - [ui-safari-tizen] directPlay: 0
    INFO - [ui-safari-tizen] directStream: 1

    This plays fine:

    Codec: H264 - MPEG-4 AVC (part 10) (avc1)
    Resolution: 3840x1602
    Display Resolution: 3840x1600
    Frame rate: 23.976216
    Decoded format: Planar 4:2:0 YUV
    Audio: TrueHD 3F2M2R/LFE 48000 Hz bits per sample 32

    This is terrible:

    Codec: MPEG-H Part2/HEVS (H.265)
    Resolution: 3840x1632
    Display resolution: 3840x1606
    Frame rate: 23.976216
    Decoded format: Planar 4:2:0 YUV 10-bit LE
    Audio: DTS Audio 3F2R/LFE 48000 Hz 1536 kb/s

    Many thanks
