[Openchrome-users] 720x576Noscale does not work

[Robin Gilks]

> Hello,
>
> On my VIA SP8000 I cannot get 720x576Noscale to work @ 24-bit color.
> The result is a warped or wrapped picture.
> It works fine at 16-bit color. Plain 720x576 does work @ 24-bit color.
> Why Oh Why? I did check several sites but could not find the cure.
