To identify your graphics card driver
If you find that you do need to update your driver, visit http://www.autodesk.com/autocad-graphicscard to look for a certified driver for your graphics card. If you do not find one, visit the graphics card manufacturer's website.
Note: If the graphics card manufacturer does not have an updated driver, check the system manufacturer's website. Companies like IBM, Hewlett Packard, and Dell often supply their own system drivers.
