LCD: Can I Attach My Monitor To More Than One?

You can try attaching your monitor to more than one computer using a KVM switch. But, a word of warning, KVM switches can weaken the video signal and cause monitors to ghost or pixilate. If you do use a KVM switch, try to use the shortest available cable between each of your computers and the KVM switch and between the KVM switch and the monitor.

You might purchase a KVM switch at electronic retail shop.
