Buying a new computer – PAY ATTENTION TO THE VIDEO

I am starting to see new computers with no VGA video output, just DVI. Some people don’t want to purchase a new monitor with their computer due to financial or other reasons.

The problem is that there are a number of DVI connectors. It isn’t as simple as just connecting DVI to VGA. The five basic connectors are

  • DVI-I Single Link
  • DVI-I Dual Link
  • DVI-D Single Link
  • DVI-D Dual Link
  • DVI-A

The problem is further compounded by the fact that computer manufacturers don’t seem to be too quick to include a DVI to VGA adapter. Add to that the fact that the adapters are almost impossible to find in local stores as of March 2012. I suspect that you will begin to see the adapters in stock at some point but right now, mail order is your best bet.

There is also the option of a DVI to HDMI connector. I am using a 27 inch Television as my main monitor. I connected that from the DVI-D Dual Link to HDMI with a conversion cable. The picture is great.

So, if you are a consultant, you will probably need to stock at least one each of the adapters. I had two DVI-A’s so I purchased 2 each of the other varieties. That amounted to $80.
You can see a good description of the DVI connectors at
Also, if you are purchasing a DVI cable (because you need one that is longer than the included cable or no cable was included) be aware that you will need to get the correct DVI version
