ATI Radeon Mobility 9700 @ 1440x900 | why not available?

hello world.

I own a Asus A6V laptop, that won't offer the 1440x900 resolution, which I would need for a 19" widescreen TFT, I consider to buy. It won't work with the original nor with the Radeon Omega Drivers 2.6.87 (Catalyst 5.12) driver, which I just tried out.

But there are a lot of 17" laptops that come with a ATI Radeon Mobility 9700, that support 1440x900 since it's the display's native resolution.

So is there any chance to get 1440x900 running?

Would be very very grateful for a solution or any hints!

regards,

Is that resolution higher htan your native screen's resolution? Most only offer the main screen's native resolution as the highest possible. Also...sometimes you can't even go that high on a 2nd display(although I think most recent laptops/GPU's allow this).

My native screen has 1280x800 pixels. Anyway I want the 1440x900 resolution for the secondary display (external VGA connector).

I can go much higher (up to 2048x1536 for each of the two displays), but there is no widescreen resolution after 1280x800.

I am convinced this is a driver issue only!

If OEM-tag-checking at the beginning of the installation was cracked, I could try the Mobility 9700-driver of some 17" laptop, that comes with 1440x900 as native resolution.

the resolutions simply need to be added for that card in the driver its pretty easy to do. there is a thread about how to do it somewhere i forget

I'm still not convinced it's necessarily gonna work. You can always try the links on this site to get you the ATI Mobility Catalyst drivers. Those aren't OEM specific(except for that check if you go through ATI's site...using the links elsewhere here gets you around that...the driver itself does NOT check). However, I think it checks your laptop screen and usually doesn't give you a higher resolution than what it can handle, even for an external display.

Someone correct me if I'm wrong...I've just never seen that option on other laptops.

Hi,

I'm spamming this post pretty much in all the threads where people are having issues dirving external widescreens from their Mobility Radeon card. Sorry if this is against the rules; there are so many threads to sort through for a person who searches, I figure I should put MY answer in as many of the places (and they're all appropriate) as I can.

I was having the same issue with my Mobility Radeon 7500 and Widescreen. I got it to work (with quite a bit of effort), and just wrote up a webpage summary and posted it to my personal website.

I hope it's OK to link; best to get the information (and pictures) off there. All the real credit goes to those who wrote ModTool.

I am running in to the same problem, and that link seems to be busted. Any help?

Thanks!
