Using a laptop on an external monitor question

[bork]

I want to use my laptop on my Bravia.  I bought the necessary cables and hooked it up, and got exactly what I wanted the first time, which is the same display on both the laptop and the TV at the same time.  However when I went to change the resolution, something happened and now I cannot display on both simultaneously.  I can either do one or the other, and or dual monitor.  How can I fix this?

you might have a special hot key on your keyboard that will cycle through the different display configurations. Most arent available from the display settings in windows as its more of a hardware thing. That is unless your laptop has a good graphics card built into it. Then it might be a special thing in the driver settings or something. But look for a computer/tv screen type button its on most laptops i've fucked around with and use the hotkey to activate it and see what happens.

Sorry cant be much more help
