This process will work on both Windows and Mac PCs and should allow for seamless streaming once the two devices are connected. Navigate to the video that you want to play and double click it, it will begin playing on the TV, and you’ll be able to use the VLC controls on your device to control the video. Now click on Media in the top menu and select Open File from the dropdown. When it works, your TV will pop up in the list, select it, and VLC will begin casting to your TV. VLC might take a few minutes to pick up your TV but if it’s struggling, try disconnecting and reconnecting the device and the TV from the Wifi.
Then select Renderer from the dropdown menu you’ll see that it will automatically scan for devices. First, start up your VLC player and click on Playback in the top menu.
