Ripped from the item description:
The microprocessor-controlled, multi-frequency operation of the monitors allows you to change, replace, or upgrade your system unit or use increasingly sophisticated applications, without replacing the monitor. All standard VGA, SVGA, and XGA applications will run without modification, saving additional expense both in program alterations and in retraining of staff.
You've got to be kidding me. Adjustable refresh rate is a key feature nowadays? I can't remember the last monitor that didn't run all VGA, SVGA, and XGA applications without modification. 🙂
