[Openchrome-users] TV-out grayscale and cropped on sp13000/openchrome/720x576Noscale

[Simon Kagstrom]

Hello!

(Resending because of improper mailing list subscription.)


I have some problems getting tv-out to work well with my Via
sp13000. I use a s-video connection to my TV (which is a 5-year old
fairly good widescreen TV).

My problem is that the 720x576Noscale mode gives a slightly cropped
image, only something like 700x520 pixels actually fit on the screen
(most is shown with the TV in 4x3 mode). Also, the image is often
gray-scale, although this can be fixed by switching back and forth
between 720x576Noscale and other modes.

The other modes (720x576 etc) are, as expected, blurry, but at least
always works color-wise. They sometimes appear to be too small
though. Although hard to judge from, it seems that the best picture I
get is with the Via logo when the computer boots.

I've tried both the latest svn-openchrome (without libXvMc, which I
haven't been able to compile yet) and the stock Debian/Testing X.org
6.9 driver and it looks the same with both options.


It seems like some other people have similar problems with fitting the
output on a widescreen TV:

Could this be a widescreen TV issue?
