I am running a multi-channel system, and the monitors are going to be placed side by side. I want the channels to be synchronized, and I have a plan, but I need to know how to reset the vertical retrace on each card. Does anybody know of any commands that allow the vertical retrace to be reset? I can make a call to change the display settings, but it takes about half a second and it is not very predictable. Any suggestions will be greatly appreciated.
