The QueBec II does not detect a VGA signal. What is wrong?

In order to work, the QueBec II needs to detect a signal on the horizontal sync pin. The easiest way to make sure this is happening is to connect your source directly to your display which you then turn on to see if you get a picture.

If you have a long cable between your PC and the QueBec II, the voltage may drop below the level detectable by the QueBec II. Try to move the QueBec II closer to your PC and see if this solves your problem. The QueBec II does not interfere with EDID communication.
