DVI was originally designed to be the end all, be all of Video analog and digital switching. It can (depending on capabilities of the source, display and cable) support VGA (RGB/HV) analog video as well as Digital TMDS Single link or Dual link signals.
DVI-I supports both the analog and digital signals. The Digital signals supported can be single or dual link. You cannot tell by looking at the connector of the device whether or not it supports analog video or single or dual link. Why? Many connectors on devices have all of the necessary pins, but they are unconnected inside the device. You should check the devices specifications to see what types of DVI signals are supported.
DVI-A supports simply the analog VGA compatible signal exclusively. DVI to VGA connections are always actually DVI-A.
DVI-D supports only the digital signals. DVI-D can be single or dual link.
mini DVI Switcher FAQ:
Nobody usually needs a DVI-I connection. Only one format (digital or analog) can be active at one time.
Most DVI Switchers are DVI-D. For DVI-A (VGA) switching, use a DVI to VGA adapter or cable and then just use a VGA switcher - save money!
Consider before buying if you need other signals to be switched as well. Also consider if you may need DVI dual link in your future. Monitors over 22" are now often capable of dual DVI links. HDTV's on the other hand are almost exclusively Single link.

Simply connect your DVI display to the Switcher's display output. Then, using the four high quality DVI cables that come with the 4x1 HDTV Switcher, plug each one into the four DVI source devices, then connect them to the Switcher's inputs. Once the source devices and the display are powered on and connected, you simply switch between source devices using the RMT-4IR remote control or your own universal remote.
