Cable Matters[Ultra High Speed HDMI Certified] 2-Pack 48Gbps 8K HDMI Cable 6.6 ft / 2m with 8K@60Hz, 4K@240Hz and HDR Support for PS5, Xbox Series X/S, RTX3080/3090, RX 6800/6900, Apple TV, and More

Used to run from an 8k switcher for AppleTV, and some video game systems to a 4k 120hz tv. All functions work out of the box, including sound and power control, full speed full res. Apparently the 8k setup is required for 4k@120 which is what I needed and the 4k cables only support 60hz. Picture quality is excellent.Cable is a bit thick and stiff which was a major plus as I lost hold of the pull string and could actually push the cable through the tube! Solid connectors hold well with no wobble, no spotty connectivity at all.

these ULTRA-high-speed cables fixed my problems, I was having intermittent signal issues with 4k/144hz and some regular old high speed cables. Also utilizing a dual-monitor KVM switch, so the color coded ends are a nice addition. Cables feel high quality, yet still plenty flexible.

I recently upgraded my home entertainment setup with the Cable Matters Ultra High Speed HDMI cables, and the difference is mind-blowing.

Never experienced any sluggishness.The 2-pack is a fantastic value, especially considering the quality you're getting. It's always great to have a spare cable, and Cable Matters doesn't disappoint with this offering. I have 6 cords total, with 2 in storage just in case.Whether you're a cinephile, a gamer, or just someone who appreciates top-quality audio and video, these cables are a must-have. Cable Matters has earned my trust with their reliable products, and these Ultra High-Speed HDMI cables are no exception. Elevate your entertainment – I highly recommend them!

The cable worked well to output 4k 120 Hz HDR from my gaming PC to my OLED TV. It’s HDMI 2.1 certified with the QR code, and performs to spec as advertised. But it is very thick and stiff, about as thick as my pinky finger. I initially had it plugged into an HDMI switcher and it was so stiff that it caused the lightweight switcher to point up into the air. The thickness is to be expected for a 20 foot HDMI 2.1 cable, but I had concerns about the strain it could put on my HDMI inputs so I’ve decided to use a thinner fiber optic cable instead.

I had a customer order this cable for an install. I decided to give it a try because the title said that the cable was certified. However, this cable comes in a plain bag without the QR code to verify the certification status. It worked fine, but I'm not convinced that it is what it claims to be without the QR code proof.As a professional in the technology industry, I give this advice about HDMI cables.1. Don’t use the cable that came with the device. They are often HDMI 1.4 and of low quality.2. HDMI 2.1 cables only. They are the most capable and will future proof your setup for years to come.3. Use the shortest HDMI cable you can get away with. The longer the cable, the more chance you have of signal noise.I go with one of two aftermarket cables depending on the situation.Low to mid range configurations:For basic TV streaming, BluRay players, or lower resolution gaming consoles like the Nintendo Switch, I think a cable like this Cable Matters cable will work just fine. The price is right and these types of configurations don't require a lot of demand.This level of cable can occasionally have issues with 4k 10-bit at 60hz (Xbox One X, PS5) and HDR10 encoding in movies. HDR10+ or Dolby Digital have never worked for me with the these basic cables.High end configurations:Fusion8k is my reliable, go-to cable for high end since the latest video sources and TVs support HDR10+ and Dolby Digital. They've also been perfect to meet the demands of the latest gaming consoles like the PS5. Fusion8K are worth it for me where I invest the most in quality devices so that I don't have to waste time in troubleshooting issues.UPDATE:I've been struggling with some of the plastic molded connectors over long lengths with DolbyAtmos lately. Longer version of this cable could have the same problem. I'll leave my original rating since I reviewed it as a budget cable based on cost and construction, but I'll be sticking with upper end like the Fusion8K cables I mentioned in my original review due to its heavy duty construction and certification for longer cables.

Bought a whole bunch of these to exclusively connect a cable box, a couple good quality HDMI switches, 3 streaming devices and a sound bar to ultimately provide input to what is now an aging 65" Bravia TV. The picture and sound is crisp regardless of the route the signal takes to get to the TV.This isn't the first time I've used Cable Matters' products. Always very satisfied when using their products.

Highly recommend great quality
