When running in a Cloned desktop setup I see tearing on the secondary monitor.
This is under both Vista and Windows 7 with Desktop composition enabled.
Chipset : Mobile Intel® GM45 Express chipset with integrated Mobile Intel® GMA 4500MHD
Driver : 220.127.116.111
Two monitors, the Primary being the LCD Laptop display (1024x768), and the second being a 1024x768 LCD display driven via VGA. Both displays are running the same resolution, frame rate and bit depth.
I can understand that if I had two separate graphics card I may get tearing, but running off a single graphics chip I would have thought there would be a way to get the two outputs to be synced. Is there any APIs which might help, I've tried looking in the Graphics control panel but with no luck.
