Bias lighting and synced backlights are one of the easiest upgrades you can make to a TV setup — they raise perceived contrast, reduce eye strain, and add an immersive pop to movies and games without a lot of fuss.
Govee and Nanoleaf dominate the category, and they take two different approaches: camera-based kits that read the screen and match colors, and HDMI-capture solutions that pull the signal directly for faster, tighter sync.
For most people, a Govee HDMI sync kit or an addressable Govee strip sized for 55–65-inch TVs gives the fastest, lowest-friction install. If you want deep customization and the option to build a full lighting ecosystem, Nanoleaf’s 4D camera and lightstrip kits are an excellent choice.
Camera vs. HDMI sync backlights — which is better?
The short answer is to use HDMI capture for accuracy and low latency; use camera sync for simplicity and flexibility.
Camera sync kits mount a tiny camera near the TV (usually on the top bezel). The camera samples the display and tells the strip what colors to show. That makes installation easy — you don’t have to route video through a box — and it works across multiple inputs. Camera-based options are especially handy if you have a simple streaming stick or if your TV inputs are awkward to access. Expect a small processing delay and broadly representative colors rather than pixel-perfect accuracy.
HDMI-capture solutions (sometimes called sync boxes) sit between your source and the TV or tie into the TV’s HDMI ARC/eARC chain. Because they read the actual signal, they tend to be more accurate and faster, important for gaming or action movies where lighting should match explosions and fast cuts. The tradeoff: a capture box adds complexity (it must support all your inputs and HDR formats) and sometimes costs more. Many reviewers say HDMI capture produces the most satisfying effect for movies and fast-action games.
Best pick for easy setup (camera-free)
If you just want a fast install that “looks good and works,” Govee’s TV Backlight kits (for example, the TV Backlight 3 Lite and related kits) are a top choice. Govee ships camera and HDMI options, generous LED density, and simple app controls — plus affordable price points for 55–65-inch kits. For a straightforward bias lighting upgrade that both improves contrast and brings reactive colors to shows, a Govee strip with HDMI sync is hard to beat.
Why this works for you: you avoid complex HDMI routing, get a tidy install with adhesive strips, and still get good color matching when the kit uses HDMI sync. If you want to keep costs down and still appeal to holiday shoppers, the Govee HDMI kits are particularly saleable on affiliate pages. Check out Govee TV backlight kits on Amazon.
Best premium immersive option (camera + advanced effects)
If you treat lighting as part of the ecosystem — multiroom scenes, gradient strips, and creative control — Nanoleaf’s 4D Screen Mirror kits are worth a look. Nanoleaf’s approach pairs a camera with an addressable gradient strip and integrates deeply with Nanoleaf’s app and other panels. Reviews praise the immersive feel and easy setup, and Wired called Nanoleaf’s 4D kit “easy to install” with very compelling results for movie nights. Nanoleaf tends to cost more, but it delivers polish and ecosystem features that many buyers will happily pay for.
Why this works for you: Nanoleaf gives you an upgrade path — add panels, sync other lights, and use more advanced scenes — which is great for higher-AOV affiliate content (people who spend more per purchase). Shop Nanoleaf 4D kits.”
Installation & placement tips for even color
You can screw this up and still have it look better than stock TV speakers, but do these things right and the effect goes from “neat” to “wow.”
- Measure before you buy. For a 55–65-inch TV, buy a strip sized for that range. If you trim lightstrips, trim only at the indicated cut points.
- Clean the mounting surface. Wipe the TV back with isopropyl alcohol or a mild cleaner; adhesive works best on dust-free plastic or metal.
- Use the included HDMI extender or sync box if recommended. Some sticks perform poorly inside cabinets; an extender helps camera kits see the screen, and HDMI boxes keep signals clean.
- Position the camera carefully. If you use a camera kit, center it on the top bezel and keep it stable — wobble equals jittery lighting.
- Avoid direct reflections. Mount strips so the light washes the wall behind the TV rather than shining into the room; that improves perceived contrast.
- Calibrate brightness. Make the backlight bright enough to influence perceived contrast, but dim enough that it doesn’t cause glare. Bias lighting is meant to be subtle — not a disco.

Troubleshooting common sync problems
- Colors lag or “float.” For camera-based kits, try reducing camera smoothing in the app or moving the camera for a clearer view. For HDMI solutions, check that the sync box supports your HDR format (Dolby Vision and HDR10+ sometimes need firmware updates).
- Strips flash or lose color. Re-seat the power connector, check your Wi-Fi (many kits are Wi-Fi controlled), and confirm the app firmware is current.
- Input switching breaks sync. For HDMI capture, map inputs correctly in the sync box and enable passthrough on your TV if required. Some users prefer a dedicated HDMI switch for many consoles.
Frequently asked questions (FAQs) — Latency, HDMI passthrough, and ambient light impact
Will backlights add input lag for gaming? No — the lights themselves don’t affect your TV’s video processing. However, camera-based processing can introduce a visible delay in the lighting response. If you want zero compromise for competitive gaming, use HDMI capture with minimal processing.
Do backlights interfere with HDR or color accuracy? They shouldn’t. Bias lighting improves perceived contrast without changing the TV’s internal processing. Make sure the strip doesn’t reflect into the screen, and avoid using overly warm/cool presets if you want true color fidelity.
Will ambient room light negate benefits? No — bias lighting helps most in dim rooms, but even in lit rooms, it can reduce eye strain and make colors feel richer. For real contrast improvement, keep the lights behind the TV and moderate room lighting.
