My G450 does the same (sync problem/noisy picture) on an LCD. mga-1.4.9 does it too, so I'd suspect a change in xorg-server. Resolutions other than 1024x768 come up as 1024x768 anyway. That could be the monitor trying to be smart. Sample log and xorg.conf at: http://www.wonkity.com/~wblock/mga -Warren Block * Rapid City, South Dakota USA
