LMCE can not do dual screens. In order for you to get the TV to have the LMCE screen, you need to have the laptop bootup, to LMCE either PXE or DISK, and then press and hold the "Shift" key. This will launch the AV Setup Wizard, and then you can select VGA (press "1" on your laptop keybaord") , and use its output instead of the DVI that it is set to use on the laptop screen.
That should fix you right up. For a better reference, check here http://wiki.linuxmce.com/index.php/AVWizard_Step_by_Step
Best of Luck.
Thanks for the reply.
By holding down the shift key it allows me to switch from the laptop screen to the tv or both.
So yes you can dual screens at the same time .
Again thanks for your help ,I'm well pleased its working now
