My lcd telly has stopped recognising my laptop. I've tried switching off laptop screen by pressing Function+F11.

Any idea's.

(Daughters laptop works ok)

Lead? screen settings? video card settings?

think the leads ok, (daughter laptop works ok on tv), my display setting is position 1, "plug and play monitor."

Try looking in the display properties, in mine there is a method that allows you to force a missing display connection (it's in the "set up multiple display section)

Fn + F11? Try this for a second display?

Depends on your OS but the first thing I do when I have a problem is restore the computer back to a time when it was OK. Works best for me if you do it by pressing F5 during boot up.

Try reinstalling the graphics drivers - it worked for me on a laptop today!

Otherwise give us some more info to work with - OS & graphics card make and model would be good!

thanks chaps will try that and post more info when at home.:)
