I've just connected my p4 to my LG 43UD79-B monitor
It has 4 hdmi: 2 are 30hz (1 & 2) and 2 are 60hz (3 & 4).
As I just intended to use it in 30hz mode I plugged it into hdmi 2.
The problem is that I have about a 1" black border going all around the screen. Which I don't get on my windows pcs or my other linux pc.
I've tried changing the all the monitor settings and tried all 4 ports and 4 different cables (inc the official cable).
I can get 60hz when I edit the config.txt file, but I still get this 1" boarder.
anyone got any ideas?
the pi is up to date. It was running the 64bit kernel, but I swapped back to the 32bit one to see if that changed anything. It didn't.
