Hi, could anyone point me to a cheap way to switch quickly between my xbox and Mac using the same screen. In my local shop it's 60+. I'm thinking there must be somewhere cheaper. Here's a diagram to illustrate better what I need...

Cheap switchers invariably degrade the signal. I'd suggest investigating whether it's possible to plug both into the screen using one of the alternative inputs. If you're trying to plug in both I'm presuming it's a TV with a VGA-in option. Could you for example use Component on the 360 -> TV connection?
If you'll be using a Pro, you've got no issues - you can plug the Pro into the DVI port and the 360 into the VGA port, and use the monitor input switching.
hey dudes I have the same problem..I have a vga flat screen monitor with only one port which I am using for my pc.I want t buy a mac mini but I don't wanna throw away my pc.I want to use both with the same screen mouse keyboard and speakers.PLZ tell me how can i do this.![]()
