Windows 8 - After Standby monitor displays "Imput signal out of range"

Currently I have a dual monitor computer as my primary here at work. the main monitor is a 21" widescreen ViewSonic and the secondary screen is a 19" HP Compaq monitor. When booting up the computer or during use the two monitors work fine. However is the computer goes to Sleep or standby mode, the second monitor (HP monitor) gives an error message "Input single out of range". If I adjust the monitor resolution the screen returns to normal (even when the settings are returned to their original setting prior to the issue).

 

This issue only seems to occur on the current operating system (Windows 8 Enterprise). On several flavor of Windows 7 this issue never occurred. The only thing unusual installed on the machine is Start8. But the issue occurred prior to installing Start8.

 

Anyone experiencing anything similar?
