"Somebody" elected the LogMeIn.com (free version) Option Blank Screen but "nobody" will admit it; "nobody" was connected when I tried to unravel this; I could not use the attached monitor with LogMeIn because it informed me it was blanked by another user. RealVNC connected but just showed me the blank monitor. I could use RDP and interact that way.
After trying all kinds of ways to recover use of the screen, I uninstalled LogMeIn.com.. which requires a restart to complete (if you want to reinstall it). After restart the Blank Screen continues (to my surprise), RealVNC still shows blank screen but now Remote Desktop cannot connect. The server responds to Ping, it's running the software I expect and showing the data drives I need.
HELP.... what can I do to regain use of the monitor?? It didn't even show the POST during the restart. I've got a tech request to LogMeIn but that can take 48 hours -- if they even have a solution!
