Just to let you know I tried the Push2TV on my new computer with a new 23" HDTV as a second monitor and it was a disaster.
The first thing you do is a bunch of updates. WiDi as well as Push2TV need updated. Sounds simple right? Just wait. The computer with Windows 8.1 kept saying there were compatibility issues. I spent hours on tech support with Netgear and could never keep a connection. At one point they told me steps to take to reset the adapter and changed the language!
After hours of frustration and red eyes I took the Push2TV back to Best Buy and bought an adapter to connect directly. You can get adapters for about any situation it seems. Hope this helps you avoid some unnecessary frustration. They are great at the Best Buy store about helping you out.
