I have a problem with connection my display (Philips 226E9) via HDMI port. There is no difference whether I try to connect my display as a single screen or as a secondary. I have already test it on another computer with same cable and it works fine. When this screen connected as a secondary xrandr command shows only screen which is connected via VGA:
xrandr: Failed to get size of gamma for output default
