I recently purchased this HDMI cable, and I am extremely impressed with its performance! The build quality is top-notch, with durable connectors and a flexible yet sturdy design. I used it to connect my TV to a gaming console, and the picture quality is crystal clear with zero issues.The cable delivers excellent 4K video and high-quality sound, with no noticeable signal loss or flickering. It also supports HDR, which has really enhanced my viewing experience. Setup was a breeze — just plug it in and go!What I really appreciate is how affordable it is compared to other cables on the market. The performance far exceeds my expectations, especially at this price point. If you’re looking for a reliable, high-performance HDMI cable, this one is a great choice!Highly recommend!

This is the 4th 10m active optical HDMI cable I've been through trying to get my RTX 4000 series GPU to play ball with my LG C9.The other 3 cables I've tried included top brands such as Cable Matters and Blustream but they all suffered from what I assume are signal drops or handshake issues when using 4K 120Hz HDR and G-SYNC (the C9 is G-SYNC compatible). The TV frequently would go black for several seconds (regardless of using desktop, in-game or when streaming video), repeatedly triggering the 'instant game response' message. Frustrating to say the least!I was beginning to lose hope as I wasn't 100% sure if it was the TV, HDMI cable or GPU causing the issue, but I was fairly confident it was the cable given that moving the PC closer to the TV and using a shorter cable worked just fine.I know 10m is a lot, but active/optical cables are designed specifically for transmitting up to 48 Gbps over longer distances, and running 4k 120Hz 10 bit colour depth (the C9 panel doesn't support 12 bit) uses bandwidth of around 40 Gbps...well below the 'certified' 48Gbps these cables can supposedly handle.This cable from RUIPRO actually works! After 3 days of use it's not dropped once and is rock solid at 4K 120Hz G-SYNC HDR 4:4:4 10 bit depth.It's also very well constructed...thick enough to provide good protection and very flexible making routing the cable through trunking a breeze.I can see why this cable gets a lot of mentions on AV enthusiast forums. It's expensive...but it's the only cable I've tried that actually does what I need, so great job RUIPRO!If this cable goes the way of the others I've tried after a while, I'll come back and update this review.

Just in case it helps anyone—it works. 4:4:4 / 4K / 120hz / 10bit all work concurrently now on a 9070 xt.Only negative is my tv sometimes loses signal when switching out of hdr or changing refresh rate which requires me to turn my other monitor off and on again. This happens only when all of the standards mentioned above are enabled so it’s either the cable at its limit or a driver issue. Not the biggest deal but I’ll mention it.*edit - black screen was due to VRR. Seems there is an issue with its implementation on Windows; there’s a ‘fix’ that lessened its impact but turning VRR on and off again also works. Not related to cable at all, seemingly.
