Once you know how many drivers there are using the <a href='CountGfxDrivers().htm'>CountGfxDrivers()</a>, you can iterate through them with <a href='GfxDriverName$.htm'>GfxDriverName$</a> and display them for the user to choose from. Once the user has chosen (or you decide), you can set the graphics driver with this command.<br>
