Code:

video=1024x768@60

Of course you can also set the native resolution instead of 1024x768 (which is a setting that virtually any display/monitor can handle).
After you have changed that file run the

Code:

sudo update-grub

command and restart the machine to look if that worked.

This doesn't help
thanks anyway
maybe i'll have to wait for future kernel update?

Instead of waiting I would go ahead and report your problem to the Intel developers. They need to know about a problem to be able to fix it.
