Dear all,
I currently have 2 Philips touch screen displays (1920x1080) connected to a NVIDIA NVS 310 graphics card installed on a Windows 7 (32 bit).
When I extend the desktop (Win 7 properties) to these monitors, the touch screen inputs working correctly (i.e when I touch the middle screen the touch is there, left is left etc. etc).
If I use NVIDIA mosaic mode and connect the screens into a unique display, the touch screens do not work as expected. Since Windows sees the computer as one widescreen mosaic (3840 x 1080) but for the touch the resolution is only 1920 X 1080, as if the 3840 x 1080 screen has been compressed into a single display of 1920 x 1080. So when I touch the left screen on its left edge it will detect it there, if I touch the right screen on its right edge it will detect it there. But if I drag my finger from one extreme to the other, the pointer has a twice speed that of the finger, and when I’m in the middle of a monitor I’m in the middle of the mosaic. In the follow link you can see a video with the problem:
