Bests & Worsts Reviews from Amazon

I didn't realize their are three types of DVI connectors: DVI-I, DVI-D and DVI-A. This adapter fits DVI-I ports, which transfer both a digital and an analog signal. I happen to have a docking port with DVI-D, which is digital only, and can not therefore transfer an analog signal. The adapter won't even fit the DVI-D port. And just fo interests, DVI-A is an analog only DVI port - in essence a VGA transfer with a DVI connector - you don't see to many of these. So, don't make the same mistake I did. Be sure to check that your docking port or video card has a DVI-I connector before buying this adapter. It will have 4 pin holes around a long slender horizontal pin hole at one end of the port. Check Wikipedia for more info on these ports.
