thx MonkeyDriveExpress, guess mine was 'linkified BY a lazified'
here is what somebody else said about them:
"51.75 are very much Alpha Drivers, not everything works as it should.
Dualview doesn't work properly, it wants to reboot continually and still no TV-out. Also noted that after about 1hrs use the Desktop Icons revert back to default. (thx Almighty1)
People with problem Dell US UXGA screens only get 640x480 and 1600x1200 no other resolutions. (at least 1600x1200 works now)
Others have noted big drops in 3Dmark 2k1, and nearly all have noted lower quality in games.
These drivers are only here for you to have a look at the new layout and have a play with the new features. Don't rely on these for everyday use !!"
