Have you checked the troubleshooting options on https://wiki.archlinux.org/index.php/Intel_graphics. I also recall an intel issue with recent kernels, but can't put my hand on a link. The problems experienced with some are listed in the wiki.
There are *some* issues with intel gpu's and recent kernels. I can't use multiple monitors in most of the cases as the i915 module misinterpret possible resolutions, for example.

I'm stuck on aur/linux-lts49 on my Zotac CI547 in the meanwhile as everything works there. But better than nothing - or 1024x768 ;)
Thanks guys. The wiki doesn't list my exact issue, so I'll try booting into linux-lts when I get home and see if that helps. Cheers, Bennett
