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!
Step 1: Computer Video Output.
Step 2: Adapter Cables and Adapters.
Note: The Comodore 1701 and related monitors supported the chroma and luma inputs. No connection to Cyber Technology.
Step 3: Make Your Own Adapter.
Note: Have not tried this myself yet.
Step 4: Technology Can Surprise You.
Step 5: The Computer.
Note: You do not need that many cables. We were just testing quite a lot of things to see what worked.
Step 6: Graphics.
Step 7: B&W Tv.
Step 8: Test Hack.
Note: Have a "CGA" card somewhere but did not take the time to look for it.
Step 9: The TV the Media Said Was Worthless.
Step 10: Advanced.
To access the linux boxes and raspberry pi, you will need to install a vnc server or use xrdp:
$ sudo apt-get install xrdp.
Note the gui does not need to be running on the raspberry pi. Better if it is not.
Step 11: Arduino
Even the Arduino can be hooked to a composite monitor with siftware that supports the TV.out libary/
Step 12: Keychain Monitor.

Step 13: Regular Lcds.
Miniature lcs have their place too especially for reporting.
Step 14: Text Only Terminals Can Be Good Too.
Text terminals have their uses too, especially with embedded systems, networking equipment, and for debugging servers.
Step 15: Trs-80 B&w Monitor Hack.
Try this at your own risk.
Almost had forgotten about this At one time I had a Commodore computer or two and needed another monitor, but did not want to spend several hundred dollars for another monitor. This was probably one of my first hardware hacks. The Trs-80 model one monitor was basically a composite monitor but required a +5 v dc line.
Model 1 video connector
The TRS-80 Model 1 monitor was actually a black and white RCA television set with most of the guts taken out. Because the chassis was connected to the power mains, Radio Shack added an optical isolator to help prevent shocks. The output of the TRS-80 was 5 volts to power the optoisolator, and a standard 2 volt composite video signal. If you want to have a bigger monitor, you can wire up a DIN connector with pins 4 and 5 and connect that to the video input of your TV (or VCR or whatever).
