Govee HDMI 2 1 Sync Box 2 AI Sync Box with TV Backlight Supports 8K 60Hz 4K 144Hz

I don't know why people mess around with the camera based TV backlight systems, when an HDMI pass-through system like this works SO much better. It's plug and play easy to install, works perfectly with no calibration needed, and it hides out of sight instead of adding an ugly obstruction top dead center of your screen. The backlights themselves are pretty good - although if you have an 85" TV this *barely* covers, you will have dark spots in the corners where the lights don't quite reach. They stick well though, I haven't had any problems with the lights falling off the TV at all. The main attraction though is the AI Sync Box, and the Govee phone app to control it. You can connect up to TEN other Govee lights to it, and map them to zones on the TV with the app so they are all controlled by the AI Sync Box when your TV is on - and now your *entire room* changes color with your TV! I have no interest in going to the theater anymore, my own living room looks more amazing now with all these lights. When adding other lights to your setup, just make sure the Govee product is "Movie Watching Dream View" compatible - some of their products only work with the "Scenic" or "Music" Dream View modes, and won't work with this product. I've found that most of their products are Movie Watching Dream View compatible though - even many of the outdoor lights! The regular Govee light bulbs work great with this. Another cool feature if you are a gamer, the "AI Identification" option in the mobile app can be enabled to add special lighting effects for specific games - make the lights go crazy when you get a pentakill in League of Legends, or make the lights flash colors when you get hit by an item in Mario Kart for example. This only supports a preset list of ~50 games right now, but it has many of the most popular titles in there, and they seem to be expanding support for new games. The HDMI pass-through, the high quality mobile app, and the easy integration with other Govee products makes this the obvious best choice for upgrading your home theater. Govee support is also fantastic, and the mobile app has a built-in social platform which at first I found annoying but has actually been a great source for tips and advice on Govee products from other users.

This sync box works extremely well and adds a noticeable level of immersion without sacrificing video quality. Setup was straightforward, and it passed through 4K at high refresh rates with no issues. The backlight response is fast, accurate, and noticeably better than camera-based solutions since it pulls color data directly from the HDMI signal. It works great for gaming, movies, and general TV use, and the lighting effects feel smooth rather than distracting. The Govee app is easy to use and offers plenty of customization options to fine-tune brightness, color accuracy, and effects. If you want dynamic backlighting and still need full HDMI 2.1 features, this is a solid upgrade and absolutely worth it. Read more

The media could not be loaded. This is a huge upgrade over the T2 camera model I used before. The lights are so much brighter, and of course, the 'no camera' feature means no more fighting reflections and always needing to calibrate it. Installation was simple. I ended up using some other edge clamps because the included ones just didn't work and kept falling off. The lights are super sticky. I even removed them from my one TV and installed them on a newer TV a week after installation. It all looks pretty cool and makes such a big difference. I paired them with my bar lights and floor lamp using Dreamview to add some extra flair. The combination makes the room quite bright, so I don't even need to use a lamp. The box itself is great too. All formats work as I hoped. Even PC gaming manages 120Hz 4K with 12-bit colour depth. No flashing or loss in quality. The light strip on the box is also a nice addition. If I have to complain about one thing, I wish there was a simple IR remote to switch HDMI formats. Having to open the app, wait for it to load, then wait for it to connect to the unit, then tap on HDMI formats to switch to a different source is a real pain. Takes way too long. Especially if you have an Apple TV/MediaBox connected to the unit with a game console and PC and you're forever swapping around between them. Read more
