Air Play Alternative for PC

Hello there,

I have been looking for an Air Play kind of thing to use with my Windows laptop. Unfortunately my Laptop has the 1st gen Core i7 CPU and therefore doesn't have support for Intel Wireless display. I have searched quite a bit and can't find anything that is actually any good while being practical for use with a laptop.

my laptop specs:

Windows 7

Core i7 (first gen, 1.7ghz - 2.8ghz)

8GB DDR3 RAM

ATi HD4500 series 512 MB VRAM

256GB SSD

=======================================================================

UPDATE:

Sorry for not explaining the main functionality i want out of it... basically i want it to mirror my laptop (sound + Picture)

there are tons of hdmi dongles out there but they all have bad reviews and have issues here and there. so i need to know if anyone has experiance with one of them that actually works and works well.

thanks
