A:Answer If your computer does NOT support Miracast, you won't be able to transmit to your TV. I also had to purchase the 'Actiontec ScreenBeam USB Transmitter 2' for it to work. Literally took minutes to connect. Best Buy does NOT carry this product. I got an open box one from Amazon for $19.99 & works flawlessly. If you haven't purchased your receiver yet, Best Buy does sell a receiver/transmitter set, which is quite pricey.
