Hello, first of all: I'm using a Radeon 7750 in combination with a monitor via display port and a tv via the HDMI port. Most of the time I do not want a picture on the tv, only when wathcing videos, so I use xrandr scripts to switch that display on and off. And here comes my problem:
With the arrival of linux 3.13 to the [core]-repo of arch linux I switched from catalyst to the open source drivers, as they finally provide a sufficient performance. My only problem now is that the colorspace is compressed for gray values below 16 (that means every shade of gray having values of 0 to 16 look just black). That's only the case for my HDMI-output connected to my TV, which worked without problems with the catalyst drivers. Also, only the dark grays are compressed, the near-white grays show up correct. My Xorg.0.log shows that the TV on HDMI-0 supports the RGB 4:4:4 encoding (just like the monitor does): http://pastebin.com/PF6sjzu1 I found a xrandr-command "--set "Broadcast RGB" "Full"", which can be used with chips from Intel. Is there something similar for the open source ati drivers?
