Solve : Problems with projector?

1.	Solve : Problems with projector?
Answer» Hi I am having a lot of problems with my Acer ASPIRE 5552 laptop and a Dell projector. I set the RESOLUTION to 1280x768 as advised and used the windows logo key + P to SELECT Duplicate ( I have also tried Extend and Projector only) I get the presentation to display on the screen but randomly and quite often the display is switched back to Computer only, losing any display on the screen. Previously I have used this laptop and the Dell monitor without any problems The only difference is a change in venue with the projector now being ceiling mounted, though other TRAINERS have not experienced any problems . Would appreciate any help. Regards Dave
