If you're looking to split a VGA signal so that two *identical* monitors display the same thing, this might be for you. However, don't expect it to work well with two different monitors. Don't expect it to extend your desktop either. To do this you need to go beyond that single VGA connector on your motherboard and add a graphics card to your PC (if you can). One more thing: when connecting two monitors, the video may not start. at boot (the VGA driver cannot determine which monitor to sync with). In this case, try booting with the monitor turned off. Turn it back on when the download is complete.
