I got a Dell XPS L501X with a mini display port to VGA connector for my External Screen. On Displays it shows me: Acer Technologies 24" (which is the monitor) but only lets me up to 1024x768 resolution (The native resolution of this monitor is 1920x1200).
I tried adding a new mode with xrandr, but when I applied it, it reverted back to 1024x768. As far as I know, the display port is controlled by the Intel card, right?
Any ideas or suggestions would be appreciated. Thanks
