Maybe some of you know the answer to this and can direct me.
For two monitors off of a video card with dual ports, a single mouse works on either monitor--this is basic.
I am preparing to increase to three and probably four monitors and want to know if there is software that allows a single mouse to operate across all the monitors.
I believe there are two approaches to the three or four monitor setup. One, install a second video card, with standard dual output ports, and voilà,you have a single desktop on all four monitors. At least I think you do.
Two, use two desktop or desktop/laptop combination. What happens if you run two desktops simultaneously? A search I just did revealed "synergy", an open source solution to one mouse (and keyboard) for multiple monitors and computers. Are there any other solutions to this problem? What do you use if you have such a setup? Are there any watchouts? Do the operating systems have to be the same on each computer? Do the monitors have to be identical or can they vary in both size and resolution setting?
( I have Windows XP with 3072Mb RAM and reasonable hard drive size. Processor is older, specifically a Athlon 64 2.20 Ghz.)
Thanks for any replies.
