Nanoleaf 4D Screen Mirror Kit: Measure Before You Buy

2023 · From the Tech with Asher channel · Watch below or read on

I had been lighting the back of my desk setup with a plain LED bar, so Nanoleaf's 4D kit caught my eye immediately: a small camera watches your screen and maps matching colors onto a light strip behind the TV, so the picture appears to spill onto the wall. I tested it on both a computer screen and my TV. The effect is real. So is the fine print.

What comes in the box

• The camera, with a cover for its lens and a mount that sits on top of the TV, angled downward at the screen
• The light strip itself, 17 feet of it
• Four corner braces, so the strip turns the TV's corners in a smooth curve instead of a hard crease
• A control station with three buttons for scenes, music rhythm modes, and power, plus USB-C, USB-A, and power ports
• Adhesive strips for mounting everything, and setup codes for iOS and Android

The two warnings before you peel anything

First: the strip is one-time use. Once you cut and stick it, that is its shape forever, so plan before you peel. Second: the box says it supports TVs up to 85 inches, but the strip measures 17 feet. On my 55 inch TV I finished the full perimeter with only about a foot to spare. I have real doubts that 17 feet wraps a true 85 inch set. Take five minutes with a tape measure around the back of your TV before ordering, not after.

How it performs

Setup is mostly patience: route the strip, seat the corners, mount the camera, calibrate it to the screen. With simple content, two or three bold colors, the mirroring is convincing and genuinely immersive; a purple and blue scene painted the wall exactly right, and watching a robotic arm demo, the yellows tracked the motion beautifully. With busy scenes the mapping sometimes drifts: I watched purple land on top and green in the middle while a red that should have been at the bottom never appeared, even after calibrating the camera across the full screen. The 2D, 3D, and 4D modes change how aggressively the effect wraps, and cycling them is part of the fun.

The honest verdict

Nanoleaf sent me this kit to review, and my honest take is this: for movie nights, it delivers a real theater-glow upgrade, and even on a computer screen it looks great, though you will waste a lot of strip on something that small (a smaller desk kit would be a smart product, Nanoleaf). Buy it knowing three things: measure your TV first, commit before you stick, and expect the colors to be impressive most of the time rather than perfect all of the time.
