It won't make a difference anyway. Monitor driver just doesn't matter. If you really want, reinstall it as a "standard monitor." But that's not really going to improve anything.
Recently added an ATI all in wonder 9200 video card and a 1905FP Dell monitor to my Dell computer but the monitor is not recognized by my computer. when I go to device manager the only monitor that appears is my old one ( a dell trinitron 17")
