VGA Computer Monitor Tester

By on September 22, 2009

If you do not want to use your computer as a way to test the Monitor, you can always get a VGA computer monitor tester to do the job. I bought this tester many years ago and it was good as it could support many resolutions. It could run with an ac adapter or even powered by a 9 volt battery. The price is affordable and if you wish to know more about this tester please click on the photo:

    Hi Jamal,

    You can read or you can't read? I suppose that you can't read it due to very dim. In that case it could be a bad backlight.

    Such a battery has made up of carbon zinc, chloride zinc and other, so that the battery has used for long life, you can also provide more about the 9 volt battery.

    Sir, Jestine
    In pakistan, Inflation is hiking fastly. therefore, i and others mostly do use TV monitor conversion device like DANY, Gadmei D-500 and 188A type models in order to test LCD and CRT Monitor displays by RF to VGA Convertors.
    Its also tip for Low invested repairman personnel.

    thanks you
    Amir mukhtar
