Update making colors appear too red, too rich

Everything I click on to watch you can’t see clearly it’s really red I can see an outline of stuff but can not see what I am watching… very frustrating

    Just got Roku 12.0 and based on a quick test our long national nightmare may be over.  H265 issues appear to be fixed!

    I’m having the same issue across several apps on my TCL Roku Tv. Whenever I click on a video or show the picture quality is really dark with a lot of red over people’s faces. This is an issue that just started happening today and I can’t seem to find a cause for it or how to even fix it

      I have had this same issues for the past couple of years and finally found the problem / solution, that has worked for me. After months of searching around i found out that Non-4K Roku's cannot read H.265 or X265 MKV files correctly. So if you are playing a H.265 or x265 MKV file on a Roku that is not 4K you will get the red issue. Non-4K units will only read h264 or x264 MKV correctly. Once I changed the files that were too red from x265 to x264 it worked perfectly.

        Hello casinoslotguy ,

        Actually, I don't believe that is quite right, although you are correct in saying that switching to H.264 will fix the problem.  It isn't correct, however, that the problem doesn't exist on 4K-capable Rokus.  it does.

        The problem appears to be a flat-out bug in Roku's playback of BT.709 colorspace video in MKV containers encoded with the  X.265 (HEVC) codec.  It affects all models that include the video upscaler feature. This means essentially all newer model Rokus, 4K or not.

        It can be worked around by deleting the color info in the header of the MKV file, as described elsewhere in this thread, but in order for the workaround to be effective the file must be direct streamed.  Guaranteeing that isn't easy, as also described elsewhere in this thread.

    Is it also very bright and contrasty? If so, this might be the Roku HEVC bug. Go to your television's menu and select Video Signal. Make sure HDR is set to Off and set color space to bt709. That should be the workaround until Roku fixes it, if ever. But put those back to Auto if you watch a 4K HDR program.
