This is all through HDMI. I cannot go above 1024x768 or I get a black screen / no signal. This means anywhere between 1152x864 and 1920x1080 (which is what I had been set at before the issue). 1024x768 isn't exactly pretty to look at - lines and graphical glitches all over the place. 800x600 and 720x576 work as well, again with the same graphical errors.

I suppose a good start is xrandr at 1920x1080:

xrandr

xrandr sees it, the screen display sees it - hell, if I open up a workspace I can see the windows being opened there (I have to move them back to my laptop display). No clue what the issue could be. Maybe xorg.conf? It's blank at the moment - might I have to add something in?

As for my card - intel 4000 and nvida 630m.
