HDMI 2.1 Sync Box Kit 2, Includes AI Sync Box, Light Bars, and Monitor Backlight, Supports 8K@60Hz, 4K@144Hz, VRR and ALLM, Works with Matter and Alexa, RGBIC Light Strip for 27-34 inch Monitor

I can confidently say this is one of the best purchases I’ve ever made for my gaming and work setup. Right out of the box, these RGB light bars were incredibly easy to assemble. No tools, no complicated instructions — just plug them in, place them behind or beside your monitor using the included stands or adhesive, and you’re ready to go. The setup took me less than 10 minutes, and the result was instantly impressive. What really blew me away is how much of a difference these lights made in the overall vibe and feel of my space. The vibrant, customizable lighting completely transformed my desk into a futuristic, immersive zone. Whether I’m gaming, working late at night, or just relaxing with music, the ambient lighting adds a sense of depth and energy that makes everything more enjoyable. Plus, the colors are rich, smooth, and easy on the eyes — no harsh glare, which helps reduce eye strain during longer sessions. One of the best features is the ability to control everything with a smartphone app. You can easily switch between preset scenes, adjust brightness, change colors, or even sync the lights with music or gameplay for dynamic, real-time effects. It makes the whole experience feel interactive and highly personalized. The lights fit perfectly with the rest of my setup — the purple tones match my mechanical keyboard, mouse pad, and background lighting to create a cohesive, stylish aesthetic. This product doesn’t just look great — it also offers practical benefits. It enhances visibility, reduces strain from bright screens in dark rooms, and adds a clean, professional look that would impress any visitor, viewer, or client. Whether you’re a casual gamer, hardcore streamer, or remote worker looking to improve your space, these lights are a total game-changer. Bottom line: they’re affordable, easy to install, stunning to look at, and packed with features. If you’re thinking about upgrading your setup, don’t hesitate — these RGB lights are 100% worth it. Everyone should have a pair. Room is coming together

The box works great and is easy to set up. Only dropping a star because it requires external HDMI output to get the video feed so would not work with a smart TV.

Incredible value for the money! My husband was so surprised. They’re easy to assemble with tons of options for light settings. They make the room so fun.

They work great!

Looks really well and easy to install. But 2 or 3 times a week the device gets "stuck", the image in my monitor is visible but the lights dont turn on at all. Turning the device off and on doesn't help, I have to unplug all hdmi cables and the power, wait for a few seconds and then plug back in, only that fixes it

Previously I had the camera dreamview GS1 and the sync box is so much better in every single way. The colors are more accurate compared and whenever there’s a black screen the lights actually dim down unlike the camera dreamview gs1 where it would still display a color which kinda takes away from the immersion. Also the fact that you don’t need to have a camera mounted on the top of your monitor makes your setup look clean and tidy. 100% recommend

The kit itself works great and the lighting effects are impressive, but it’s only compatible with computer monitors. I called customer support to ask if there was an extension or adapter for an actual TV, and they said there isn’t — and that was the end of the conversation. Very disappointing since using it with my TV was the sole reason I bought it. Now I’m stuck with an expensive setup that I can’t use.

It’s a great product, has a few issues, not having many ai lights setting but more are being added, somewhat easy to install, make sure to look if there is a update available if so you can’t use it till it’s updated. Good colors and good response times.

Best ever Govee light because it might be a little bit pricey but you won’t regret it everything is great the ease of installation, color option , functionality ,value for money but there is a small problem and it is that it doesn’t have ANY good scenes it just has 20 and the scenes are really bad also the brightness is great.

One of the best accessories you can add to your gaming space, Color lighting and saturation are easily customizable through either graphics driver control panels or the Govee App with Smartphones

Great product, Some limitations, and a little pricey. This is no doubt a cool product that works well outside of 4K on high refresh rates, and VRR. It is also limited with the HDMI when running a multiple monitor setup. For your average gamer with 1 Monitor, and you can afford this and game at 1440 or 1080...Buy It! It enhances the experience so much. Where the limitations come into play. At 4K it advertises that it can handle a higher refresh rate (VRR and 144Hz) I find anything over 120Hz my monitor will not accept that refresh rate. Also, I tried adding this to my TV 55", it does not have the ability to power a longer LED light strip. The side lighting post work with the TV. My 5080 graphics card only has 2 HDMI ports, and my prior 4080 only had 1 HDMI port. The limitation this has is multi monitor set-up. My HDMI port is used for a sensor panel. So I did DP to HDMI cable into the Govee box... The lighting works fine doing this. However the output to the Monitor is only 60Hz and will not support VRR. It needs to be only HDMI all the way through. Adapters kill the refresh rate. However the lighting still works.
