Hello, I am having problems with a Sony Laptop PCG-GRT715M and a Philips cBright XG2 LC 4441, I am having problems with being able to get the display on both monitors. The laptop has a NVIDIA Geforce Go5600 graphics card and have already updated the drivers to the latest version. I am able to get the desktop onto the projector but the laptop is blank, or the desktop is on the laptop but only the mouse appears on a blank wallpaper on the projector and there is no mouse on the laptop, so it is either one or the other! Also when the desktop is viewed on the projector and I open a presentation it only appears on the laptop! I have been playing around with the display settings such as setting the primary monitor and the resolution. I have also been pressing the Function key and F7 but this doesn't do anything! The main reason for having it on both screens is that it is mainly used for presentation use at work. I have ran out of ideas so I hope someone elses knows! Thank You For Your Help.
