Hey folks
I've got a weird problem here similar to what I'm seeing in a lot of discussion boards with no definitive fixes.
I have a ProStar (essentially a Clevo) P150HM laptop with ATI Radeon 6990M. On the website for the 6990M, it's specs clearly list that it supports 2560x1600 (though with a footnote indicating "Some custom resolutions require user configuration.") So I figured it would be a great idea to buy a Dell U3011 to do some photoshop work, maybe run some games though at that resolution though it's tough to say if the 6990M would keep up. Anyway, I receive the monitor a couple days ago and hook it up using the dual link DVI cable that came with the monitor...max resolution available is 1920x1080. WTF?
Other important info:
1) Driver for the 6990M is up to date. When I roll the driver back to the one included by ProStar, all of a sudden I can get resolution up to 1920x1200. Weird.
2) I've run this laptop on a 1920x1200 Asus monitor via single link DVI before no problems.
3) Called Dell and they had no clue how to fix this.
4) Emailed AMD and the guy said he's never heard of a laptop going over 1080p. So he is useless.
5) Called ProStar and he had no clue either.
6) Lot of discussion out there about tweaking either the vbios to lift some bullshit limitation put on the card, or tweaking .inf files associated with the monitor to force a resolution. Any ideas?
Personally I feel like it's the graphics card or laptop manufacturer that needs a new driver or bios to fix this. What do you guys think? What do you think the footnote from the ATI site means (http://www.amd.com/us/products/notebook/graphics/amd-radeon-6000m/amd-radeon-6990m/pages/amd-radeon-6990m.aspx#2)? Thanks for the help, I really appreciate it.
Cheers
Matt
