Did a git pull this morning. Tried different setups to get a picture using
RandR, no luck.
I used the modes line with NoRandR and that works. I also tried it earlier with
a virtual line. The effect is the same. I get picture at 1920x1080, but the
image seems slightly too big for the tv. The left, right and bottom edges fall
off screen.
I did notice however that if I connect an 15" (1024x768) lcd to the DVI
interface, the picture is cloned to the tv in RandR mode. But whatever I try
with xrandr, I can't get the right resolution on the tv. If I disconnect the
15" and use xrandr again, the picture on the tv goes black.
So it seems there's some load detection problem on the HDMI connector.
What can I test to sort this out?
