For the 7600GS, this is the Gigabyte web page.
http://www.gigabyte.com.tw/Products/...ProductID=2334
Gigabyte has a link at the bottom of the page, listing resolutions. Page 2
has the resolution you are looking for.
http://www.gigabyte.com.tw/FileList/...dard_modes.pdf
*******
This is the page for PV-T44A-WANG, the 6200a. There isn't really any
reassurances of what modes are supported here.
http://www.xfxforce.com/web/product/...rationId=79772
If I look at the release notes of the latest Nvidia driver release -
http://us.download.nvidia.com/Window...ease_Notes.pdf
On page 50 is a list of cards and their combined resolution options. The
top of page 54 lists this:
1440 x 900 32 60 70 72 75 85 100 120 140 144 150 170 200
That is 1440x900 in 32 bit color, at refresh rates from 60 to 200. Now,
we know that this is an analog specification (because the digital wouldn't
support refresh that high), so that specification is what the VGA
connector is capable of. The digital DVI specification should not support
quite as high a refresh rate.
So I cannot say I have 100% assurance that both analog and digital support
that resolution on the 6200A, because the release notes document doesn't
present the resolution information as nicely as the Gigabyte document
does. It probably does, but I cannot guarantee it.
