I have just got a new Sony TV and when set to 2160p only (1080p is OK) I get a thin white line down the right hand side of the screen.
This does not happen for other devices attached to the TV such as Xbox or Netflix/Youtube using the Smart TV functions.
Any know issues?
I have to change the screen in the V^ box to 1080p for it to go away.
Have you tried any other connected 2160p devices to see if the issue is still there?
It sound like the tv overscan setting is not set up correctly.
There is a white line or flickering line on the top or right and left edges of the TV screen.
Solved - I changed the background from grey to black for the display bars in the V6 settings.
