I have LG 4K TV 43UF680T running WebOS 2.0 and it can't play 4K movies from my external HDD. It reads my HDD drives + contents and I can play other movies/videos without problem, even some of it are 4K videos like demos etc. But recently I downloaded a 4K movie in mkv format (HEVC/x265), copy it to my ext HDD and my LG TV read it as an UHD (I can see it on the thumbnail) video but when I play it it's stuttering, mirrored and have a horizontal pink line below the screen. I don't know what the problem is, but I have other x265 movies as well but they're all playing well although non of them are UHD movies just 1080p Bluray rip movies. So I guess the problem is not from the HEVC/x265 compability.
If anybody here can help me it will be much appreciated. Thanks in advance.
