Dvd player as a computer monitor? You remember that we used a composite monitor back in the Mythtv instructables. (https://www.instructables.com/id/Setting-up-a-computer-based-DVR-with-Mythtv-for-l/). Here we are going to do a variation on that but use a dvd player as the monitor. Though I meant this to be for text based server and computers Certain low gui desktops could work also.
Most but not all computer servers are going to the command line I.e no graphics. Even as I understand it, MSWindows 8 server is going to the command line. Never hurts to have a back up monitor for an emergency, for portability, or if you just want to go retro.

Note: Tried two old portable B&W tv's and it did not work.
Update: Using the dvd player as a monitor for Raspbmc!
