Ubuntu 12.04
GeForce GT 640 with 4 video outputs: 1xVGA, 2xDVI, 1xHDMI
Have 3 connected LCDs: 2 identical - via DVIs, and one different - via 1xVGA.
Video drivers: 304.116
In KDE settings all refresh rates are set to the same 60Hz (But monitors' OSD report more precise values 59.xxx)
Tearing happens on both DVI-connected LCD's and does not happen on VGA-connected one.
I also confirm this.
