Thank you for the info. However if there is a fault with the projector or cabling, why do other laptops work on this projector? I have tried this laptop on another board & I could get the display up, so I think there is something wrong with the graphics on the laptop.

Towards the end of last week the display on a teachers IWB stopped. I have checked all cables. Check 'clone' on display settings. Used Funtion F3 several times. I have connected her laptop to a different IWB where a display shows using her laptop. I have connected a different laptop to her IWB which also works. I have run out of ideas. Any answers please?
