hi. I try not to use the panels to light up the TV or the screen. I use a group of multicolored light bulbs so that they cover the area of the screen, but slightly smaller than the screen. The illumination from such a curtain of balls goes to the sides, but it even better simulates the reflected light from the screen in the room. And there are no sharp stripes like the panels.
sphere lights can be of different sizes (I set 3-8% power). They can be white or of very different colors, then the imitation of reflected light from the screen will be more interesting, colored in different classrooms, as in a real cinema.
