highgfx does not work an the a500 with the indivision....
Sure it does. I've used it on my 2000, which is basically the same thing. Suppose I could try it on my 500, as well. Your monitor may not be able to sync to the particular refresh rate it uses, or you may need to do the firmware update.
If you post more specifics, e.g., what exactly happens when you try to use it, you might get a more useful answer.
