I had to revert back to the previous version because the newly released NViDIa Control Panel (bundled with the drivers) is missing "Change signal or HD format" under the "Video & television" tab.
It is essential to me to be able to switch to 1080p from 1080i.
On 1080i setting (the only available when setting multiple displays) my HDMI output "shakes" really bad.
I always thought that the new version (of anything) should be an improvement over the previous version... WTF?
I guess I should not be surprised, look at the SH series...
