Latest HDMI 2.1 Interface: Govee AI Sync Box 2 adopts the latest HDMI 2.1 interface for data transmission, enabling screen and lighting synchronization, and supporting resolutions of up to 8K at 60Hz and 4K at 144Hz. Note: Automatic signal switching is not supported when multiple devices are connected.
Unique CogniGlow Technology: Govee Sync Box uses AI to automatically recognize images and text, determining trigger conditions to match specific lighting effects. HDMI 2.1 Sync Box supports VRR and ALLM, reducing screen tearing and latency, providing a seamless experience.
RGBWIC Four-Color Mixing: An RGBWIC LED light strip ensures purer white light and accurate color blending for vibrant effects, making it better suited for game visuals.
High-Density Light Strip: With 75 LEDs/m and a brightness of 450 lumens/m, the high-density light strip cooperates with our Sync Box to provide a brighter and more comfortable experience.
Matter Support: Seamlessly integrates with multiple smart ecosystems, supporting convenient voice control.(Only lighting-related functions are supported).
DreamView: Synchronize colors across multiple Govee lights to create an immersive gaming environment. Equally supports Dolby vision and Doldy atmos.
A special note for using HDR, HDR10+, and Dolby Vision: Due to the functional characteristics, when you turn on HDR, HDR1O+, or Dolby Vision, the saturation of the light’s color might decrease, which is normal. You can also adjust the saturation in the app to achieve a satisfying lighting effect.

Worth it
Really good and easy to setup.It can also sync with other govee bulbs and lamps which creates even better results.But it feels like it cannot create few colors like Brown or grey.

Next-Level Immersive Lighting Experience!
This Govee Sync Box 2 completely transforms my TV setup. The colors are vivid, responsive, and perfectly match the on-screen action — it makes movies and gaming so much more immersive. Setup was fast and simple, and the app gives tons of customization options.HDMI 2.1 support works flawlessly with my 4K/120Hz setup, and there’s zero lag. The AI sync feature is surprisingly accurate too. Overall, it’s a premium upgrade that delivers on performance and visual impact — absolutely worth it!

Amazing Product But Not Perfect
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.

If you’re looking for mood lighting for your TV this is the gold standard
It is amazing how this box looks and it’s lights look around the TV it’s very much understated but does make a huge impact when you’re watching television having the different color lights that match what’s going on with the TV. It was super instantly easy to install, it functions very very well and is easy to control. We had no issues with any of the lights falling off as the adhesive attached to the back of the LEDs works well. Love this unit way more than a camera unit.

The review I wish I saw—and why this deserves 5 stars (even if it’s not perfect)
A lot of what I see other people saying is slightly misleading. I see a mix of:•AAAA AMAZING PERFECT!!•extremely underwhelming.•Good but… *proceeds to list fatal flaws*Here’s my honest two cents. What it does well, what it doesn’t, and why I’m never owning a TV without one again. Let’s get into it.Immersion: This thing is insane. If you’ve never experienced anything like it before, prepare to be hooked. It adds a whole new layer to the experience—it’s not just watching anymore, it’s experiencing. Explosions light up the room, emotional scenes set the mood, and suddenly your TV feels alive. It’s hard to find words for how much it changes your enjoyment of what you’re watching. ColorsResponse and HDR: The responsiveness is great, no noticeable lag. (It supports 4K at 144Hz, and if you need 8K for your TV… well, you’re probably crazy, but it does handle it at 60Hz.) I’ve seen camera-based systems, and honestly, they don’t even come close in speed. Not at all. HDR has been great for me too, though it really just depends on your TV. If you’re seeing complaints about that, I wouldn’t let that be the reason why you wouldn’t buy. The backlight is very accurate to what’s happening on the edges of the screen. Sure, if you’re the type to sit and stare at the lights instead of the show for five minutes, waiting for an “AHA!” moment to catch something slightly off, you might be able to find something. But in my experience, it’s spot on… I haven’t seen anything like blacks showing as green or other weird issues.HDMI switching: Soo easy. You just press a button on the sync-box and it switches instantly to the other inputs. No need to shuffle HDMI cords around, and you can have 4 different devices plugged into the ports. (Only uses one HDMI cord going to your TV, so you can have more devices that aren’t associated with the sync-box)What needs work?-The app interface needs some adjustments to make it more user friendly. Some of the customizations I would argue make the product worth using aren’t enabled by default. It’s not that big of a deal but having to dig around the app is not ideal, just to make it work correctly. I’ve already had two firmware updates so it seems like they are working on it actively.-Compatibility with streaming devices can be a bit quirky, it doesn’t turn off by default, even with the right settings (I use a Roku). But let me stress: this is not a big deal. I almost didn’t buy it because of one review mentioning this, and honestly, I’m glad I didn’t listen. There’s literally a button on the device to turn it off. Literally. That said, I don’t even recommend getting up to press it—this thing is fully Alexa-compatible. In fact, I’d say Alexa is almost necessary for the full experience. You can turn it on and off, adjust the brightness, and skip using the app altogether (after you set it up). It really ties everything together.What needs “work”? (my tips)-ITS TOO HARSH, EW. Adjust your settings! Make it less bright, tone down saturation, fine tune the colors with the provided adjustments, change the relative brightness, turn on or off the sound effects, change the softness of the sound effects, adjust the distance of the TV from the wall, change the- (do you get my point? it’s really adjustable lol)-It doesn’t work with my TV! Unfortunately this guy does not work with a smart TV, it needs some sort of HDMI input to intercept. Even though the camera systems aren’t as accurate if you aren’t willing to use some sort of other device like a roku or streaming box, you’ll have to use one of those. Or another TV.-I don’t even have a flat wall behind my TV this won’t work… This guy is BRIGHT, see my picture and videos, I did a color and video test to demonstrate it. You don’t NEED a flat wall behind it, but I’m sure it helps enhance the viewing experience even more.All in all, this product impressed me. The immersion it creates is insane, but honestly? What sets this apart from others is the price. It’s unbeatable. The hue system is so much more expensive, govee is on to something with this lineup. Sure, you can always find small things wrong with a product and I’m not claiming it’s perfect, nothing good ever is. But don’t let others sway you away from choosing this, it’s not a “compromise” even though it’s cheaper than similar systems.

Really nice sync box, without any delay!I had some trouble at the beginning with the leds flickering badly. I’ve found out that if you increase the brightness > 75%, they work a LOT better. Like 15% or less brightness will flicker like crazy. Also turn on black bar elimination.For me, the CEC works well. I don’t however use the input switching since all my HDMIs goes trough my AV receiver, then the receiver to the sync box.

Absolutely fantastic product, if you’re a gamer, this is a Must have! Purely amazing! I was a doubter at first but this Sync Box just rocks! I don’t need to reprogram or code anything, it just does what it needs to do, Sync lights to my Monitor, LED light strips is too big for a Gaming PC setup tho, better for 34″ monitors, not so much for 27″ screens, bending light strip required if you have a 27″ setup

Works good pretty decent only down side dosent work with the high end Roku box but other than that it’s decent. Really good for gaming

Works really well! Was debating on getting the other Govee lights that have the camera but wasn’t super keen on having that on the top of the TV – the other option was the Philips one but the price was too out of my budget. If you’re in between those I would recommend these – cheaper option and works really well!! Have to use it through HDMI. We watch everything through our PS5 system so we’ve had no issues – everything syncs well while gaming and watching shows/movies. We also purchased the govee lamp and it syncs perfectly with it as well!

It’s great device except for the part that’s most important switching inputs.If you have more than one input and you aren’t using a receiver to depend on signal well good luck making it recognize the device.this has also made me have to unplug my tv it almost bricks the tv sometimes cause tv defaults to it as input but won’t show anything on screen.soft bricks my TV G4 OLED, you heard that right it bugs out so hard it makes the tv freeze on black screen and only way to fix the tv is to unplug it! Not the govee sync box, not turning off the tv, no you need to hard reset the tv, that’s how garbage and tedious this device is.
