I just started looking into these for my professor I do research with. We have two computers and a dual monitor display between them. Ideally it'd be nice to just switch from one to the other while only using those two monitors and a single mouse and keyboard. So I started looking at KVM switches and got kind of confused about "max resolution" and if I really need DVI or VGA. The two monitors are Dell E190s (http://www.dell.com/ed/business/p/dell-e190s/pd), both of which are 1280x1024 in landscape setup.
Right now there is a DMS-59 on an older computer that is currently split into two DVI cables going to either monitor. On the other computer, there is only a single DVI and single VGA output on the card (which I believe is a GT 610). Would I need to change this out for something that can properly split a DVI signal (like the DMS-59) or can I buy a single DVI to 2xDVI splitter? I ask this because on several sites I keep reading that you can and cannot do that if you want an extended desktop display.
Granted I get the above figured out, would something like this be what I need?
