I guess that I'm wondering why a file developed in 2001 by ATI...would be in demand on any system.
Monitors generally don't require drivers, video functions do. It's your ATI video drivers that determine monitor support.
I'm curious as to the site which asserted that this file is the cure for anything...since it's an ATI driver file, it should be included in any set of drivers for ATI video chips/cards which might require it.
You might try just uninstalling your current video drivers...and then reinstalling the current ones or updated versions.
