I am currently running Windows 7 Professional 64 bit service pack 1. I am also using an ATI Radeon HD 5570 card. I have currently have 2 Samsung monitors hooked up and I just recently received a 46" LCD and mounted it in my office. I do not have the ability to run cables and want to extend my desktop to the mounted TV. Not knowing how to perform this task wirelessly, I went to my local HHGregg and the salesman suggested I purchase a ROKU 2 XS.
Will I be able to extend my desktop and use the TV as a 3rd monitor? I will have to transfer everything over a private network wirelessly. If I can do this, how do I set it up?
