I am shopping locally here for a good KVM switch. For now, I am not
even sure what type should I get. What are advantages to have DVI

KVM is about $20, where is DVI is $100. If money is no object, DVI KVM
is better than VGA? Thanks for all info you can share.
I run and work on many different makes and models of PC-compatible
computers. VGA and PS/2 are the lowest-common-denominator interfaces --
especially for servers, retail point of sale, and business desktops.
So, I have an 8-port KVM with VGA and PS/2 connectors, and a monitor,
keyboard, and mouse to match. I use various PS/2-to-USB, DVI-I-to-VGA,
DisplayPort-to-VGA, etc., adapters at the computer end of the KVM
cables. I don't use USB or microphones through the KVM. I use a
passive line-level mixer for speakers.
Determining compatibility before making a purchase is tough. Hardware
tends to be identified by product manufacturer name and model number,
while software (device drivers) tends to be identified by chip
manufacturer name and part number. After searching and reading whatever
you can, you will need to buy a KVM, plug it in, and find out for
yourself. Make sure you buy the KVM through a vendor that will allow
you to use it for a week or two, and return it if you don't like it. I
went through several KVM's before finding one (IOGEAR GCS78) that worked
reliably with Windows and Linux, and put the hotkeys where they didn't
interfere with other applications (notably games).
