I just updated my 5800 series Radeon, and now my display won't go past 1152 x 864. I know my laptop can go to 1440x900. What's going on?

Sounds like the update hasn't installed correctly.

You might want to uninstall the drivers in Uninstall a Program and graphics adapter in Device Manager, and then reboot and reinstall the updated drivers.
