Does the ATI Radeon 9100 IGP support TFT widescreen (1680 x 1050)?

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View

I have an ASUS P4R800-V Deluxe motherboard with integrated ATI Radeon
9100 IGP graphics.

I have just purchased a 22" Cibox C2202 widescreen monitor, and I am
using Windows XP Professional SP2.

I have updated the driver to version

I cannot see any resolution setting for 1680 x 1050 when I look in the
"List All Modes..." box on the "Adapter" tab in the Advanced Display

Can you please tell me if the ATI Radeon 9100 IGP support a widescreen
TFT with 1680 x 1050 resolution, and if so, what I need to do to be
able to see that mode listed?

Many thanks,

That video card certain has enough memory to support 1680x1050.  My
undeerstanding of how cards and monitors interact to get the list of
available resolutions is a bit shakey, but here goes:

There is apparently a standard for embedding that information into the
monitor, and an interface video cards can use to query that info.
Apparently, some monitors don't bother with that, and possibly some
cards don't ask.

I'm not sure if the operating system can thwart that exchange, but it
definitely seeks to help.  You can install monitor "drivers" that
include the list of available resolutions.  I don't see one available
for your monitor, or even a listing for that monitor on the
manufacturer's site.

There are third party applications, Powerstrip for instance, that helps
you force the monitor into specific modes.  Powerstrip also permits you
to create a driver for your monitor from known specifications.

A simple test to make sure that your card and monitor can produce the
resolution you desire is to boot with a linux live cd.  It's screen
settings are generally more flexible and you should be able to
specifically select that output.

Good luck.

Thanks very much for the quick response, Grinder. Although your
suggestions didn't directly solve my problem, they did give me the
confidence to keep looking before buying a new graphics card!

The solution that worked for me was to install an ATI "Omega
Driver" (not supplied by ATI) from here:

After that, the resolution I wanted was available and works perfectly!

Hope this is useful to someone else one day when Googling for answers!
