The verdict
A simple way to add ambient lighting to a TV without wiring an HDMI box, and the camera approach works with any source. Pick the size that matches your screen. Camera-based syncing can be affected by room light and glare, so a Hue-style HDMI box is more exact for gaming.
The Govee TV Backlight 3 is a light strip with a dual-camera system that watches the screen and matches the glow behind it. Govee lists a 4MP lens, 60 RGBWIC LEDs per meter, AI color mapping, black-bar elimination and Matter support. It comes as H2A40 for 55 to 65 inch TVs and H2A41 for 75 to 85 inch TVs, and it needs no HDMI connection because it reads the picture with its camera.
