I have an excellent computer monitor that has a degauss function, so I'd like to use that to play my TATE shmups (and all the rest of my console games).
So, I was wondering if there was a device to allow console hook-up to my computer monitor, or if you have something else similar to it... And where I could get one.
EDIT:
Also... I absolutely do not want to buy any extra system-specific cables to play my games on my monitor. I use the red, white, yellow cables to hook all of my consoles up to the TV (even NES, SNES etc.), and would like to use those same cords to hook them up to my computer monitor (if such a device exists.....

Thanks for any/all help.
