Not given Funtionalität on any computer

I have 3 PC '+ 1 notebook (which are all connected via a network which is connected to the router to the Internet, and the other network is a gigabyte network and has no access to the public grid) of which two equipped with more modern graphics cards with the ports VGA and DVI connector. and that work very well with this Adapter Converter. The image quality is OK.
My notebook I have also with the resolution setting 1024x768 pixel setting (higher setting is not possible) and also works.

After I have studied this VGA to HDMI converter adapter converter through its paces, I imagine that:

It consists of older PC with an older graphics card, whose resolution is the cause.
As I now see it, my computer has the problem with the older graphics card. I think I discovered the source of error. I'll keep this article. Following conclusion is to say that a newer ATI Radeon (9200 9250, etc.) graphics card has DVI connector with VGA ago. Then that resolution is resolved.

Soon I write an extensive customer and product review with all purchased at your article, I have compiled my conditioning and work tadelos, except for this above Kompatiblitätsproblem with the older graphics card.
