VGA Signal Generator Monitor Testing Tool

Easily test your VGA monitor(s) with this handy tool.
To test a monitor, you must disconnect the connection cable to your monitor from the device it is connected to
and plug it into the VGA test generator. The generator is equipped with 15 different settings, which can be selected with the push button.
The various settings can be seen on the underside of the circuit board, the choice of which can be seen on the display on the front.
The settings include black/white grid display, full red, blue and green image, color separation, etc.

The monitor tester is also a very handy tool to quickly test large batches of screens without connecting them to a computer.
The monitor tester works on a 9V battery and is therefore also easy to carry (9V battery not included).
