I had been using the govee line for several years and it worked ok, the issue was the camera placement and speed of which the lights would sync with the screen. I wanted a box that did not need a camera. I read about fancy leds and they seemed like the premier go to choice. I stumbled across a few reddit posts of people discussing the pros and cons of various options. Someone mentioned the Linkind ET8 HDMI 2.1 Sync Box and how happy they were with it. I did some digging around and came across a few older videos of the previous version ET6 and had great results. Long story short I ordered the ET8 and hooked my xbox into it and absolutely love this setup. The ET8 is my go to choice for all led backlighting needs from here forward. Bravo to a great product with a reasonable price. Thank you!

good performance

I've tried several TV light strips before, but this one is by far the best. Zero latency, corner-to-corner coverage, highly recommend. I use it for both gaming and streaming, and it never disappoints!!!!

Setup is a little difficult

Very good product, but it took me a little longer than expected to get the HDMI sync box setup correctly. Once it was working, the colors were amazing, but setup instructions could be clearer.

Works ok for movies, app is slow, had to restart it a few times.

Makes gaming way cooler

I bought this mainly for gaming and honestly it's awesome. When explosions or bright scenes happen, the lights react super fast and the whole wall lights up. Hard to explain, but it makes the screen feel bigger somehow. My friends noticed immediately and we spent a night just trying all the game modes. Totally worth it.

Movie nights feel different

Installed behind my 75 inch TV and the effect is amazing. Watching movies in a dark room feels so immersive. The color sync actually works really well with dark and bright scenes, and the music mode is surprisingly fun too.

Easy setup

Took me maybe 20 minutes to install. The strip bends around the corners pretty easily. Camera-free design is nice. Haven't tried Alexa yet, but the AiDot app seems fine.

Kinda surprised me

I thought this would be gimmicky, but after a few days of using it, I really like it. It changes the vibe of the room, and the corner-to-corner coverage is legit. Sometimes setup was tricky, but once it's done, it's smooth.

Sync works mostly good but sometimes colors slightly off. Still happy.

App problem

Colors match the screen fast, no lag. My only complaint is app interface is a bit clunky. Otherwise love it.

Big TV looks amazing

Using it on 85 inch TV and coverage is perfect. The wall glow looks really nice and smooth. Makes the whole setup look premium without spending thousands.

Almost perfect

Colors great, reacts fast. Only reason 4 stars is that HDMI plug is short, had to rearrange setup.

Great for parties

We hooked this up for a small party, music mode is sick. Lights flash to beats, everyone asked where I got it.

Really cool

First I was skeptical but seeing it live is wow. The HDI sync actually works well with every HDMI device I tried.

FAQs

How does the Linkind ET8 Smart TV Backlight match on-screen colors?

+

Its HDMI 2.1 sync box reads video from a connected HDMI device, while LumiSync matches the backlight to on-screen colors. No camera is needed, making it ideal for movies and gaming without a camera mounted on your TV.

Does it sync with Netflix or other built-in smart TV apps?

+

No. TV apps running directly on your television cannot provide video to the sync box. To sync streaming content, use an external HDMI streaming device, such as a Fire TV Stick, connected through the box.

Does the Linkind ET8 support 4K gaming with PS5 or Xbox?

+

Yes. ET8 supports up to 4K at 144Hz or 8K at 60Hz, plus VRR and ALLM. Your available resolution and refresh rate depend on your console or PC, TV, and HDMI connections.

How many HDMI devices can I connect directly?

+

The sync box has one HDMI input and one HDMI output. Connect your console or streaming device to HDMI IN, then connect HDMI OUT to your TV. To use another source directly, switch the device connected to HDMI IN.

What TV sizes does it fit, and can I trim the strip?

+

The 20-foot strip fits TVs up to 90 inches; 100-inch TVs are outside its stated fit range. Use the included mounting brackets and trim excess strip only at the designated gold contact lines, following the manual.

What should I check if the lights don’t match the screen?

+

Select TV Sync Mode and check that your video source passes through the sync box. In the AiDot app, open Light Positioning and verify the strip length, installation direction, and corner positions.
