Bought a tv way out of my price range cause..yolo? anyway its an OLED 55c6p to test it out i have some 4k mkv files. Hooking the usb directly to the tv the files worked.. hooking it through my bluray player which is hdmi'd to the tv gave an error for invalid resolution. That method (hdd to bluray to tv) works fine with files from the 720-1080mkv files Thoughts?
