Dolby Vision Appearing Green

[Nishanth Noble]

Hi!

I am having an LG UH850V TV that supports HDR 10 and Dolby Vision. However, while playing Dolby Vision movies, the screen appears green but the audio is clear.

How do I fix this.

WebOS has issues playing Dolby Vision files encoded in MKV container.  It can play DV files encoded in MP4 container without any issues.

Actually this is happening to me as well.

@Nishanth Noble 

It is possible that one of the "expert mode settings" is not correct for some media types being decoded. I did see mention of a bug in some sort of "lookup table" for this stuff, in another forum. Try temporarily turning off the "dynamic tone-mapping" in settings -> Picture -> Picture Mode Settings. Then see if the affected test videos are improved or not.

If no difference, try testing with other modes off or on as needed, BUT- DO REMEMBER your initial settings, so you can get it back to your normal settings for regular TV viewing. Take a photo of your settings on your phone or camera before starting changing anything.

Another thing you could look for is "Enhanced Format". Some Sony and other TV's have these below, so if you can find your settings for these, use the SECOND option, NOT the first one, for Dolby Vision to work properly.
• Enhanced format = 4K@120Hz 4:4:4 HDR10
• Enhanced format (Dolby Vision) = 4K@60Hz 4:4:4 HDR Dolby Vision

NOTE: if you DO find that (e.g. dynamic tone-mapping) is the culprit, then report it to your country LG Support site, as this forum is ONLY a peer-to-peer enthusiasts forum, and is NOT OWNED OR RUN BY LG. If users do that, then there is more chance of a fix from LG.

I do not have problems with Dolby Vision on Netflix. I did not test mkv video. I have UH8507 and the latest firmware.
