Asus P4SDR-VM have the same VGA as your matsonic; so try that link enter P4SDR-VM in the first line of search box (located on the left side towards the top of the page) and click search. It will then ask you for selection of OS; select you OS, and click on search again. From resulting page download the vga drivers. I am hoping they will work for you as well. Goodluck Just for reference Asus's Specs are here.
