I am currently running 2 LG 1080 LG HD TV's (42" and 47")as dual monitors for my old Dell desktop.

Finally decided to take the plunge and try to build a new desktop which I plan to use strictly for my Photoshop illustration and BIAB/RB music production.
I'll use the old Dell for online and all other stuff.

Is there a simple way to switch the dual TV monitors between the 2 computers?
I see there are various KVM switch boxes but can't seem to determine by their descriptions if they will do what I want.
Some are over $100 and don't want to spend that if it's not going to work.

Any computer geek/gurus out there who have done this and what is the least expensive way outside of plugging and unplugging the DVI/VGA/HDMI connections?

Thanks for any help.
