Unfortunately, we found the video output is quite unstable, i.e. there
is something like an interference wave running down the picture, every
display line seems to jiggle left and right by about 2-3 pixels. Another
nc4200 shows the same pattern, so it's probably a software problem. Both
machines are running Gentoo Linux with X.org 18.104.22.168. We haven't tried
either under Windows yet as it would mean a complete reinstallation. Any
experiences with this misbehavior? Maybe something to do with the two
different rendering pipes in the gfx adaptor? I never quite got what
they are meant for anyway, Pipe A seems to be unused here and the CRT
uses the same one as the internal display.
Re: Blurry video on a HP nc4200
could be caused by the conversion of digital-analog(ouput on
laptop)-digital(projector). This image shifting is common with lcd displays
with analog inputs. Its quite possible that the same symptom is applicable
to an lcd projector.
