Title:
External monitor scaling problem
Status in Linux:
New
Status in linux package in Ubuntu:
Won't Fix
Bug description:
Binary package hint: grub2
I have a Dell XPS studio 16 that has an attached an external monitor.
In /etc/default/grub I have: GRUB_GFXMODE=1920x1080-24
This seems to work fine on the laptop monitor. However, on the
external monitor the picture is not scaled correctly. The picture is
underscanned.The effect is the same as if I leave the underscan option
in ATI Catalyst Control Center at its default value. By setting the
underscan to 0% in the Catalyst Control Center the problem is resolved
in xorg. But unfortunately the startup splash screen is not scaled
correctly and there is a black frame around the splash screen.
Using Ubuntu 10.10 64-bit with the fglrx driver.

What you expected to happen: That the picture on the external monitor
cover the entire screen.
What happened instead: The picture is covered by a black frame, similar to
the underscan effect in the ATI Catalyst Control Center.
