Displays in terminal server turns black if left idle for long

Problem:  Displays of an application gets black if it was left unattended for few hours. 

Analysis: Mouse hovering could some times get the display back. Or moving to another display would solve the issue.
  •  Initially I thought it to be a graphic driver issue, updated the driver software, Still the problem persisted. Then disabled hard ware acceleration but the problem was still present. 
  • Then I thought it may be some performance issue in the terminal server. But the problem was repeatable even if a single client was opened also.
  •  Guessed that the issue might be with bitmaps caching of remote desktop protocol (RDP). Hence, disabled the "Persistent bitmap caching" for the terminal server client and it worked.
 Solution: Disabling the "Persistent bitmap caching" for the remote clients
