Cable Matters 2-Pack 8K HDMI Keystone Jack, HDMI Coupler Keystone | 8K@60Hz / 4K@120Hz, Female-to-Female Coupler, HDMI 2.1, Wall Plate Compatible, Low-Profile Design

I recently incorporated the HDMI Keystone Jack with 8K 60Hz capabilities into my home entertainment setup. While there are several positive aspects to this product, there's also a noteworthy caveat regarding its size. Firstly, the plug mechanism of this jack is impressive in terms of durability. It feels strong and well-built, suggesting that it can withstand regular use without issues. This robustness is crucial for any component that's frequently connected and disconnected, as it ensures longevity and reliability. The picture quality remains uncompromised with this jack. (Not sure about of 8K at 60Hz, but there's no noticeable decrease in quality at 4k 120 hz). The visuals are as sharp and clear as they are when directly connected, which is a testament to the jack's capability to transmit high-resolution signals effectively. Additionally, the keystone clip mechanism is equally durable. It securely locks into place, providing a stable and reliable connection. This sturdiness is essential for maintaining a consistent and interruption-free viewing experience. However, the size of the jack poses a challenge. It's somewhat larger than expected, which made it difficult to fit two of these jacks side by side in a Leviton 6 port keystone plate. This could be a concern for those with limited space or who require multiple jacks in close proximity. In summary, the HDMI Keystone Jack with 8K 60Hz offers strong and durable mechanisms, ensuring both longevity and sustained picture quality. However, potential buyers should be aware of its larger size, particularly if planning to install multiple jacks in a confined space

I've been using a number of these for months. I've seen no issues with 4k HDR at 60hz. I have these setup with one behind the TV and an HDMI cable in the wall that connects to another one of these below the TV. The HDMI then goes into my AVR. Using all HDMI 2.1 Certified CL3 rated HDMI cables from infinite cables for the connections. Each HDMI chain length totals to 12'. I wanted to address a few negatives I saw in other reviews that I don't think are the fault of these keystone jacks. 1. One reviewer suggested these only work when the front is the output. This has not been my experience. Each instance where I use these there are two involved and on one the front is the input while the other the front is the output. No problems here. 2. One reviewer suggested they don't work with CEC. That has not been my experience. I use CEC with these and I've seen no problem with CEC working. 3. One reviewer suggested they don't work with ARC. Again, I've seen no issue there. I use ARC without any problems. 4. One reviewer suggested they are too big to allow for a good fit in a standard wall size. I have 2/4 walls and while these are pretty large connectors I didn't have any trouble getting them to fit with the HDMI cable inside the wall. Yes there is some strain on the cable as it does touch the back wall but it is not what I would consider significant. In one location I even have these in a gang box which reduces the space at the back just a bit more and it's still what I would consider acceptable strain/bend on the HDMI cable. Your mileage may vary depending on the HDMI cable used. I have no complaints. If I notice any issues I'll be sure to update this review.

They work great and snug in fitting into the jack

I bought the Cable Matters 2-pack 8K HDMI keystone jacks for a cleaner HDMI setup, and they work like they are supposed to. The installation was straightforward, and the fit was good for a keystone-style wall plate setup. Once installed, it gives the area a much cleaner look compared to having loose HDMI cables hanging around. The performance has been good for my use. I have not had any connection issues, and the signal works like expected. I like that they support newer HDMI specs like 8K 60Hz and 4K 120Hz, so they feel more future-proof than using older basic HDMI inserts. The build quality feels solid enough, and getting two in the pack is a good value if you are wiring more than one location or want a spare. It is not an exciting product, but it does exactly what it is supposed to do. Would I buy it again? Yes. It works, looks clean, and does the job.

I used these while running HDMI through a wall plate for a TV setup, and they worked exactly the way I hoped. They snap right into a standard keystone wall plate and basically turn the wall into a clean HDMI pass-through. Instead of a cable hanging out of the drywall like some home theater crime scene, you get a nice finished connection. I tested it with a 4K setup and didn’t notice any signal issues. These are rated to support high bandwidth HDMI like 8K60 or 4K120, which is nice if you’re running newer gear. The build quality feels solid and the connections hold tight. Once installed, it just works and looks professional. Overall this is a small part that makes a big difference. If you’re doing any kind of in-wall HDMI run, this is a simple way to make the install look clean instead of “I promise it’s temporary.”
