Incorrect external display resolution

[Misha Shnurapet]

I have a Sony BRAVIA 32" TV that I connect to my Dell mini laptop via a VGA cable. The TV picture has to be 1280x768 px (and it was in Fedora 13 and 14, though the monitor settings applet used to call it a 72" display it worked well).

Now on F15 the TV is detected as "Unknown" and the system gives me a 1024x768 px only as the maximum option.

How do I correct this?
