Dual input monitors – can you use VGA and DVI ports at the same time?

Hi all,

We’re getting a PS3 here at work for testing and I want to know if I can plug it (via a hdmi -> dvi cable) to my monitor at the same time as my good old (vga) computer and switch between the two?

Sounds unlikely, but if there’s any solution that doesn’t involve me unplugging and plugging things back in again it would be nice.

Thanks!
