You need to turn the function on in your TV. Using your magic remote, go to Settings > Network > then select Miracast™ / Intel's WiDi, > toggle the feature on so your TV can begin searching nearby compatible devices. There is a Re-Search button on there that you can click in the event your TV is unable to find a compatible device.^IFV
The wifi direct, widi/miracast are all greyed out in my tv. I am able to connect to both wifi and wired connections but these functions are still disabled. How do I enable them on my tv?
