Hi

I have a hp 6730b laptop running  ubuntu 9.04 and have an external monitor
hp LE2201w 22"

I am suppose to get a max of 2560 x 1600 resolution according to the spec.

I am getting only  1280 x 1024

# sudo lspci -v for the display and vga shows this

Anyone can suggest a fix / workaround ?

Thanks
