On Dell Latitude E5540, when plugin VGA cable to a VideoProjector, the compute's screen blink and display the message : "DisplayPort Topology Notification".
The screen is never displayed to the VideoProjector. Bios and Graphic frivers are up to date
What happen ? How can I get rid of this ?
I'd appreciate an answer on this as well. I"ve gotten this with the presidents administrative support personnel and it happened about 50 times today...
Screen blinks and cancels out things she's working on or at the very least disrupts her work.
