I'd like to know if there is a way (a software, a keyboard combination, etc...) to switch between DVI and VGA screen on the same monitor. I've two PCs connected to the same monitor, far away (80cm) from me. To push the monitor button is not so easy and comfortable as could seems, moreover if you have to do it almost 20 times a day. I've tried to check on search engine/Samsung (SyncMaster SA450) site for a solution but with no success. Any suggestion? Thank you all in advance, gb
