Quest for 800x480

**ptk** · 09-29-2004, 04:58 AM

after searching through the whole forum and having a go myself,
finally gave up and concede to the fact that onboard video JUST can't do 800X480

finally resorted to using a PCI video card, which, is HARD to come by. PCI express may be, PCI is hard to find (just like usb gameport. "Game port? who uses game port nowadays)

i was lucky to have a PCI extension board lying around. but you first have to change the heatsink on the board to something shorter.

the card i managed to find is Inno3d's MX440 based. the driver allows you to define custom output resolution.

now in the process of installing. will post when i manage to get it to work

Keep us updated, as I am thinking of doing the same thing...

by the way
i sent an email to VIA to suggest more flexible resolution in the future.

Good luck! I can't get 800x480 to work on my ATi 9600. Even with the utilitiy to change the refresh rate my Xenarc won't display it correctly.

ive got onboard Geforce 4 MX and ive got it runing at 848 x 480, works fine.

dude
read the subject line. i am trying to get 800x480.
why? you might ask?

coz it's the native resolution.

i can get 848x480 on the onboard video too, so can just about everyone else.

I'm trying to get 800x480 working using a PCI Radeon 9200 card and the 7" Lilliput.

I'm using a flexible PCI-riser (I had to extend the flex-cables) and cut a small part off the gfx board using a dremel (I actually cut off a piece of the VGA connector)to get it to fit inside my custom 1-din enclosure. I also had to cut of off about one centimeter of the stock Epia TC boards heatsink.

I have not yet managed to get the exact timings for the horizontal-pane (800 pixels) so the image still lookes a little "jaggy". But the vertical is ok.

800x480x70Hz or 800x480x75Hz seems to get me the best picture on my Lilliput using the Radeion, since 60Hz looks like crap.

Some pictures:

The "low-profile" heatsink

The extended riser:

EBFoxbat, antimatter

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.
