I am hacking around with an old (CRT) VGA monitor.
What I want is to make the monitor display a blank white screen at all time, when the power is connected of course. I do not care if I cannot use my monitor for its normal job anymore.
Is it possible to short some pins of the VGA connector to mimic a blank white screen?
Or should I go to http://electronics.stackexchange.com?
Some old VGA monitors displayed white if nothing was connected. – LawrenceC – 2014-11-14T22:46:06.923
Out of curiosity - why? (I personally have no idea how to do this short of leaving a computer connected SHOWING a solid white screen all the time, so I'll decline answering.) – Shinrai – 2012-03-26T15:46:31.473
1You can make an oscilloscope from an old crt, but mine shows a message and automatically shuts of :( and I don't want to keep a computer connected. But I am not familiar with the VGA connector protocol. – Qurben – 2012-03-26T15:51:48.923
Ooooh, that sounds like fun. Good luck with that. – Shinrai – 2012-03-26T15:53:53.333
Shorting some pins on the VGA connector won't do what you want. The VGA interface includes timing signals, e.g. horizontal & vertical sync pulses. Nothing will be displayed until the monitor can recognize frequency of the pulses. BTW a white screen will cause the monitor to draw maximum electrical power from the AC line. – sawdust – 2012-03-26T19:25:50.107
Sounds like a fun project for a Raspberry Pi and a HDMI to to VGA adapter... – pelms – 2012-03-30T19:33:18.573
