Hehe, that's what I meant. Typo. Any luck with the 800x480 with any of the cards? Geforce 440 MX doesn't work?

I have used the Xenarc website 800*480 timings with 61Hz rather than 60Hz and this recognised as 852*480 (not completely sure what difference this makes). My circles do look round and the quality is better than 640*480 or 800*600.

you can get 800x4880 using Geforce 4 MX, just do custome resolution.

Have you tryed Powerstrip???
It can make all custoum resolutions possible.
I didnt try it on a Via though, but I think that it would work.

i just installed my screen and carpc yesterday (xenarc + epia10000) and was worried about this resolution issue, but it looks amazingly good at 800x600 I think ill just leave it at that.

Wow ! 10:61 Ratio

Just to make sure I got everything straight up to here
(Since I'm about to order my 7" screen too).

If I have a MII-10000 I WON'T be able to reach 800x480 with the
onboard video (S3) Controller, nor will any utility such as Powerstrip
help me.
The only option(s) with the onboard VGA is: 640x480, 800x600.

With some 3rd part PCI (such as GF440MX etc.) It's possible to reach
those resolution with custom display timings, either through NVIEW / Powerstrip.

As a side note/question...: I wonder if the free Linux driver could be "presuaded" to skip the first (600-480) scanlines, so that is would output only the remaining 480 lines and thus "simulate" a 800x480 mode...

Yes, you can get the graphics card to do that easily. That isn't the problem, the problem ist that the Lilliput screen will report it is getting a diferent resolution and won't look all that great.

Its a pity Lilliput doesn't step up and its engineers suggest powerstrip timings, rates and porch settings that give optimal results. Has anyone asked though, I wonder?

I either get 640*480 (display looks bad) or 852*480 (display looks much better) coming up on the OSD. I have using the timing values given on the Xenarc website and have tried tweaking the values in all sorts of ways, but still get only either 640*480 or 852*480 on the OSD.

Given that the card is outputing 800 pixel horizontal lines, does it matter that the screen thinks they are 852 pixel lines and samples them, persumably at 800 points, to form the pixel values it needs for its native resolution? Am I chasing something that doesn't matter in trying to get the display to realise it is being fed the correct 800*480 signal? Does the display just sample the analog signals at the points it needs to line up with its 800 native pixels? However, this wouldn't explain why the monitor looks so bad when it misdetects the 800*480 signal as 640*480. Sorry if this is a dumb question.

Exactly.
