There is such a device
located here http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=589859&Sku=D700-2208%20P&CatId=202
it is called a KVM Switch
There are few monitors on the market that have dual inputs. That is a switch that one can switch from one computer to another by hooking two different computers up to one monitor.
My friend is looking for one. The only ones that I have found are Sony and they are rather expensive (he needs a 21? since he has two monitors and one is worn out and they are both 21?). I know that Samsung seem to have a 19? monitor with such feature, but that would be too small.
What I wonder is if there is some kind of adapter or Y-connector that may have the switch so he can buy a monitor that doesn?t have the switch. If the connector/adapter would have it, he could go with that?
Any suggestions are welcome.
Thanks in advance.
