Media wall with lighting synced to the screen

The toughest part of this setup is not the woodwork, it is the picture quality. popson4 hooked a Hue Sync Box into the living room entertainment system, and right away HDR became the weak point: the box does not handle Dolby Vision or HDR10+, and with HDR10 content the TV fails to read the HDR signal, leaving films looking pale and off-color. The maker is still hoping for a fix, and meanwhile has been open that a plain backlight without the box is already very good on its own.



The rest of the room is a tidy piece of work. The screen sits in a media wall with a long electric fireplace below it, recessed alcoves with accent lighting, and ceiling downlights. A cove built from a 2x4 frame and 5/8 inch MDF carries a Hue Strip, with RGB GU10 lamps above the shelves and BR30 bulbs in standard potlight housings under the cove. Behind the screen, a Hue Strip runs around all four sides, chosen over light bars because that spreads light more evenly. The wall glow fades in a gradient with no harsh hotspots, and lights outside the entertainment area stay fixed in color so nothing pulls the eye away.



What stands out to me is the discipline in the choices. popson4 tested adding the cove strip to the sync area, decided it was too distracting, and left only the TV backlight in the sync group. Intensity stays at moderate or high around 40 percent brightness for viewing, with everything maxed for showing off the effect. The box reportedly took ten minutes to set up with no trouble, and the maker admits it has a definite cool factor, even while doubting it is worth 230 USD for most people.

Limiting the sync group to just the TV backlight seems like the smartest call here. Full-room sync demos often turn into flashing noise, and keeping the cove and alcoves static while the strip behind the screen reacts gives the effect without the circus. It trades some drama for watchability, and in a living room that seems like the right trade.

The 5/8 inch MDF on a 2x4 frame sounds like it produces a nice deep cove for the strip to sit in. How is the strip fixed along the cove, and how far from the panels does it sit? I am wondering what spacing gives that smooth fade with no visible hotspots around the whole ceiling.

Since HDR10 content through the box washes out, a splitter or downscaler that sends full 4K HDR straight to the TV while feeding the sync box a downscaled SDR copy could sidestep the whole recognition problem. It would add a device to the chain, but the lighting reaction would stay intact and the picture would keep its HDR punch.
