Bug Description
I'm running Ubuntu 13.04 on a Dell XPS 14 with integrated Intel HD 4000. The problem is that the coloring si really bad (in gradients, for example, bands of colors can be distinguished). It's like the color depth is not really 24bit.
This issue is known, and Intel never fixed it in Windows drivers (https:/
I searched and the problem is probably due to HDMI different color range (16-235); when it's "scaled" in laptop's display standard "0-255" some colors are lost.
I experienced the same issue in Ubuntu 13.10.
The package version is 2:2.21.
