In some cases the video card name may not be retrieved correctly or appear similair to "%iHSWGT15D%". We have found this is usually the result of an out of date video card driver. Check the manufactures website for the most recent version of the driver.
Using the default Micorosft supplied driver can also lead to an incorrect video card name, and will severely lower the test score for the video card. Again downloading the most recent driver available should fix this problem.
