hdmi

I set up a new system with

i5 3570k
gigabyte z77 d3h
using integrated graphics (HD4000)

and I've installed the 64bit Desktop version of 12.04. Connected to my Acer Screen via HDMI, the colors are horribly distorted. I think the biggest issue is that black appears as greenish. Over VGA everything is fine.

Interestingly, I once observed that connecting both, the VGA and the HDMI cable at the same time, solved the issue. Ubuntu thought 2 screens were connected, I mirrored the image, and over HDMI the colors looked fine. However, after a reboot I am now unable to reproduce this behavior.

I read frequently, that Intel hardware should be supported out of the box by Ubuntu but it doesn't seem to be the case here. Should I upgrade my Kernel? If so, which version would you recommend?

Thank you for your answers!

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
