When I select in the Display settings "Use limited color range (16-235)" the OSD/user interface remains at the same brightness. Why is this? I seem to recall this setting used to make also the interface darker/lighter. Now video content is correct but the interface remains too dark. Intel Haswell GPU.

 Cannot reproduce, gets brighter / darker for me   

I removed my advancedsettings.xml file and now it works. I'll check what setting in there causes this.
