Subject: RE: [Intel-gfx] RGB Problem with Intel i915 driver, i3 2010T, RGB
color output over HDMI
Date: Tue, 24 Jan 2012 15:24:04 +0000
Hello all,
This e-mail is a continuation of my previews one regarding HDMI modeline output
problems. So far with the help of Rodrigo Vivi i have manage to output the
1920x1080p@60hz mode over HDMI to my AV receiver. (To fix my previews problem i
inserted the EDID frame directly inside drm_edid.c file. So i dont read EDID
from the AV i2c bus anymore. So the mode is always set correctly.)
The issue now is that the AV reports that the signal is not in RGB mode and the
image shows some strange colors, specially on the white color (showing like
greens).
Does any one has any idea if this is a problem on the EDID or inside drm/i915?
All comments and help are very appreciated.-- Paulo Louro
