Hey guys just flashed latest vix image on mutant hd 51, I have resolution on box set to 2160p on sd channels I get a black line down right hand side of screen sometimes both left and right on some channels. Hd channels are fine. This does go away if I select 1080p. Is this just the way it is or can I fix this. I tried setting screen up in user settings on box but it doesn't need adjusting.
