Cable Matters 2-Pack 8K HDMI Keystone Jack with 8K 60Hz and 4K 120Hz (HDMI Coupler Keystone)

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.

Reliable HDMI coupler. Snapped securely into the wall plate. I mated my cable with it no problem. Wrapped the interior side around with some electrical tape just for extra security. Looks nice.

These keystone are great. They don't fit the inserts I bought very well, but I think that's because the inserts are a lesser brand. These hold the cable ends tightly and I've not had any other problems from them.

My company had to run some HDMI cables for one of my customers. I purchased these to pop into faceplates for a clean look. The problem I ran into was that the HDMI port on the backside faces the back wall. Once I plugged the HDMI cable into it the whole assembly was too deep to fit inside the wall. The cable was pressing too hard on the backside wall and would mess up this keystone jack. I purchased some 90° couplers, but then there was too much signal loss. I ended up purchasing another keystone coupler that was a pigtail design. I recommend going the pigtail route.
