Welcome to Windrivers Decrypted...talk about ressurecting old threads, but the explanation is

Answer: Click on the Vrefresh=150 Explanation: The video adapter’s refresh rate defines the number of times that the screen must be rewritten per second. The higher the resolution, the larger the number of dots that have to be written in every refresh cycle. Video adapters and monitors have a default refresh rate of 60 Hz. This is the setting guaranteed to work on most modern video adapters and monitors, even with the standard video adapter driver installed. Not all video adapters and monitors support a refresh rate of above 80 Hz. When the refresh rate is not supported, the monitor goes blank or the image becomes distorted

In other words, the vRefresh listed in the example question is wrong. Setting a refresh rate of 150 is beyond the abilities of most office monitors.
