Regarding your issue with color shifts, is this evident only when starting Windows or when resuming from hibernate? Since your ASRock board has both HDMI and DVI, have you tried using a DVI to HDMI converter and run that instead? It might be that Windows is not playing well with HDMI.
Is it possible to hide all the OSD overlays and text? I'm very curious about this (especially during initial power on and when switching inputs).
And finally, is the capacitive option worth the extra $100?
