RDP Screen Blank because of dual-monitor setups

Postby guest » Tue Nov 27, 2012 6:30 pm

Problem: You've RDP'd into a computer, e.g., in your office, from a remote computer, e.g., home, and when you return to the office, the office computer's display is asleep and you can't wake it up. You notice the computer is still on, but movng the mouse, using the keyboard, fiddling with the monitor power switch, etc., will not wake up the display.

Cause: Apparently a bug in Windows 7 with RDP. Appears related to dual-monitor setups.

Workaround: In the "Power Options" control panel, set "Turn off the display" to "Never". Because this change could result in image burn on your monitor, as well as create a security vulnerability, make sure you also set the "Screen Saver" in the "Personalize" control panel to 15 minutes and check the "On resume, display logon screen" box.
