Completely changed gaming for me
The lights were easy to set up and they look absolutely beautiful. Lots of light customization options with their app so I could tweak levels just to my liking. I can’t play video games anymore without these lights, they truly enhance the experience. Movies and shows pop as well. Definitely worth the purchase.

Absolutely loving this!
What sets this apart is that it uses the feed directly from the receiver—no bulky camera stuck to the top of the TV like other brands. Setup was super easy, and my whole family is obsessed with how much bigger and more immersive it makes the TV feel. I previously had a similar model from another company, and it was just okay. This one, though, looks fantastic—clean, bright, and way more accurate with the colors. The clip I shared is from one of the best scenes in Game of Thrones (Battle of the Blackwater), and this was filmed at 2 PM with the lights on. It looks even brighter and more incredible in a dark room. If you're on the fence, this is the one to get.

Not for more than 78 inch TV
NOT FOR ANY TV LARGER THAN 78 INCHES BEWARE. My install followed FancyLeds instruction to the letter and was short way more than the reported size of the TV size supported. Contacted customer service and their response is that I mount it closer to the center of the rear of the TV even though i was already three inches from the edge.

10/10 product
Easy set up, connection was tricky I would suggest being near your router when you go to set it up with Wi-Fi, works quickly and syncs perfectly. Really makes movie nights so much more fun and exciting!

Seamless light flow
These are perfection. Easy set up and the lights flow effortlessly with the tv with out any cameras. The only con would be I wish the standard was 3 HDMI.

Works amazing but you need a work around to get PC to display in full hdr w/ rgb
Why did you pick this product vs others?: Works great with streaming boxes but takes some work to get it to display your PC with dolby vision and 120hz etc. Now it works perfectly. I had to buy some extra items. I wanted to run my PC at 120hz from my RTX 4070 TI super. 1. Get a hdmi headless card Fueran 1080p@120hz 2. Daoistek splitter 1 in 2 out 4k@120hz 3. Export the EDID from your existing monitor and save it to the HDMI headless adapter 4. plug output 1 from the splitter to the syncbox or hdmi switcher and the hdmi headless card to output 2 Tried all tyoes of combo to get it to work correctly and this is the only reliable way for me. I now have Dolby vision, HDR, rgb, 10 bit full color. I use a hdmi switcher cause I want the lights to work with my media player, PS5 and PC. Now I just use the switcher and the signal gets sent to fancyled to display.

Creates an immersive experience
Love it! Adds such an emmersive experience to my tv viewing! I've used others that rely on a camera to mimic the colors, but there was always a delay and if my cats bumped the camera then it threw everything off. Not an issue with this thing, it relies on the video signal from the hdmi so no camera is needed. It was plug and play and honestly exceeded my expectations! This will not disappoint!
