Video Switcher 2 monitor sharing

[TantrumusMaximus]

I have a Sony CPD-G520 21" CRT which is a great monitor but recently purchased a 2405FPW from Dell... while I love this monitor it just does NOT cut it for FPS games when I play Multiplayer. I recently found I played much better and got many more frags when using the CRT. So with that in mind...

Is there anything out there that I can connect both monitors 2 and share the one video card connection? I'm not talking KVM but just a video switcher.
