Well I haven't noticed any but then again I haven't really been looking.

Non-square pixels? The hardware uses ITU-R 656 compatible more and that standard only specifies 720x576 PAL and 720x480 NTSC modes. Square pixel modes aren't endorsed by the standard. That is according to some doc I found on the web. And trying to support those modes would require fiddling with the video timing and you'd end up doing pretty much the same stuff as with matroxfb/fbset. Not to mention how much complexity it would add to the driver. -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
