Stop material for tiling on imported fbx?

ive created a media texture for the tv fbx Ive imported. When i put a texture onto the screen it comes up as a bunch of small tiled videos. When I add a texcoord to the texture sample in its blue print it doesnt change the amount of tiles on the screen, it just shows a smaller portion of the video on all of the tiles. Is there any way of getting it to just be one big video across all these tiles?

Can you show how to look UV0 of your TV mesh?

How have you laid out the uv unwrap of the screen part?
