In the game, the video screen off in the distance is animated just like TV "snow" in our world. I ran this screencap through Photoshop to brighten it up so you could see the video screen's location.
As to where this is specifically, Raz has just started up the vine-tower in his mental world. I turned him around for the heck of it. You can see the video screen until you reach the first curve in the vine. I tried seeing if I could still see it when I passed the sleeping meat but kept falling off at that point so I wasn't successful.
When I attempt to Levitate to the area where the video screen is I lose sight of the screen and just can't seem to find it again, which makes me think this might be a crack in the textures.
