Hi everyone!

I have problem with direct playback of 2160p content via DLNA server (tried Serviio and Plex) on my 4K TV LG 55UF772V. Everytime I try to playback any file (for example Elysium 4k trailer) i get error that file was not recognized. Playback from USB drive works fine, and even 2160p 10bit color coded videos are played perfectly. Anyone else encountered this problem? I presumed it is software problem, so I have updated TV to latest webos version but problem still persists.
