Okie, here's my situation (and for others who use the same hardware setup)

I am using a VIA EPIA TC-10000. It has onboard video which is base on S3 chipset. It outputs standard resolutions, ie 640x480, 800x600, 1024x768 ect.....
note that these are 4:3 aspect ratio (ie horizontal:vertical)

if you are using this board on standard VGA display, all's danty and fine.

However, for those of us using 7inch touchscreen panel from Xenac/Gain/Lilliput, it spells trouble. If u have notice, those panels are wide format, and to make it worse, it's not the more common 16:9 format which some of u assumed it to be (848x480 = 16:9). It turns out that the panel has native resolution of 800X480 (5:3).

And this is not support by the onboard video.

Some might ask why not just leave it at 848x480? it's not that far apart? it's 16:9 compare to 15:9. the fact is, it does matter. Circles ain't circles, and text don't look right (coz it's not dot for dot).

The direct alternative is to use 1280x768 (5:3). In this case, the aspect ratio issue is resolved, BUT not the text. U can barely make out your text.

Hence the quest.

ps. if you think aspect ratio for PC monitors are confusing, wait till you work with video ON PC.
