Yes I have a windows laptop.

Thanks but looked up VNC stuff and that seems I can just control a raspberry pi from my laptop?

What I want to do is use the pi to wireless display what I am seeing on my laptop screen onto my tv screen, and even better if i can set it up in a dual screen interface.

Will a raspberry pi work to stream my desktop from a laptop onto my tv screen - basically like a wireless hdmi cable?

I want to hopefully use the pi to help me wirelessly use my tv as a screen or second screen for my laptop - like an alternative to WiDi.

Can this be done?

Thanks
