Subject: VESA, EDID & flat panels
Date: Tue, 04 Oct 2005 08:53:33 +1000 [thread overview]
Message-ID: <1128380013.8267.125.camel@gaston> (raw)
Hi !
Somebody around here has access to the VESA specs ? I'm trying to figure
out if the EDID block, at least on recent flat panels, tells us wether
the panel digital input is 6:6:6 or 8:8:8 ... If it's 6:6:6, we should
enable dithering in drivers like radeon and "nv", while if 8:8:8, we
should not. If not enabling it on a 6 bits panel, we end up with crappy
looking gradients, if enabling it on a 8 bits panel, we basically end up
sending a 6 bits signal to a 8 bits panel, thus reducing the quality.
Ben.
