machine type: ThinkPad T420S GPU SandyBridge: HD3000 (intel core i5-2025M ) Operating System: Fedora 15 DeskTop Manager: Gnome 3
Problem: The only resolution mode that's available is 1600x900 with 16:9 aspect, which is the full screen. This is the native panel mode: highest resolution possible for panel. Other 16:9 aspect modes are not available.
In order to verify all possible modes with 16:9 aspect, i installed windows 7 with its video driver. As a result, all the other 16:9 modes were available and none of them blurry. The quality was very good. These are the 16:9 modes below that showed up in windows but not in Fedora 15/Linux. The panel supports all these modes below. But in Fedora 15 using the intel sandybride driver that's built in to Fedora, these mode are not available.
