Hi EEVers
I made a screen from an old labtop LCD and the MT6820-D monitor driver, and it works like it should when run over VGA.
I then tried hooking it up to my main computer through a passive HDMI to VGA converter, and this makes the screen turn on for 1sec with the desktop showing, then goes black, and shows "no signal" for a couple of seconds, then just loops like this.
The converter works without problems with a normal VGA compatible screen.
So the home made screen works, and the converter works, but they don't work together :/
Any thoughts? Could the passive converter trip the monitor driver chip in some way?
