Yes the TV will handle 4K, I have changed the display input setting inside the v6 box which from 1080p and 2160p to just 2160p which seems to have resolved the problem for now.
In addition, there also seems to be a problem with the normal non-4K channels where the image is breaking up where the image is distorted and random colours are showing, the problem primarily seems to happen on HD channels, so if you have any information on this please advise.
thank you.
