I've been using this HDMI cable for about 6 months. I bought the 34-foot wire, which turned out to be perfect for my installation. I decided to run the wire in the wall behind my desk, up through the attic, and down into the utility closet where I have my computers running. The wire powers an ultrawide monitor with a 75Hz refresh rate, and I have found absolutely no issues with it. I chose an active cable because I know that HDMI 2 and 2.1 have very limited lengths that certified and reliable cables can run, and a fiber optic cable ensures that signal degradation will not impede the picture quality or reliability. This cable has been perfect, and I will likely purchase more cables as my setup grows into different rooms of my house. One note to realize is that this cable is directional, meaning that you have to use one end of the cable in the source and one in the display---the cable cannot be reversed. It will also pass through a 1" hole in the head board inside the wall.

Perfect length and diameter.

not getting consistent 4K 120hz output, consistent signal dropping

Our new 4k DVD player would not connect to our Sony 4k projector over the cable we had been using for years. Switching to this cable solved the problem immediately.

Worked perfectly for a long projector run. Zero handshake/communication issues at 4K HDR 60Hz

Works flawlessly for 4K HDR VRR from my computer in the other room.

I went through 3 cables before landing on this one that actually functions for the configuration I want. I have an RTX4070 that I want to use to drive a TV from across the room, and it's about a 30ft cable run.

Initially, I had gotten a 35' HDMI 2.1 cable (regular copper), it would intermittently get 4k120, but would drop the signal every so often while gaming (90-120 seconds and black out for half a second or longer). Getting the GPU to negotiate the 120Hz signal was also inconsistent.

Fine, got rid of that cable, and tried an active, optical, 50' (shortest length available) HDMI 2.1 cable from Unitek. It would negotiate 4k120, but my TV would not render a signal when requesting 4k120, only backing down to 4k60 would give me a picture on the screen. I thought maybe it's defective and tried again, no dice, same deal.

In the end, I came across monoprice's offering, where it's "certified" to be able to do 8k60 and 4k120. Fine, spent a little more (price per foot). Just ran the cable, and fired up the picture, 4k120, negotiates instantly, shows a picture instantly. Boom. It works!

If you want to be sure to get the 8k60 or 4k120 signal, get this cable! Anything else and it might or might not work for you.

Good quality and performance.

Just what I was looking for.

I was referred to your company by a friend. I purchased 4 6' Ultra high-Speed HDMI cables for a new system I set up. At first I had an issue with how they were working and was not getting any help from my service provider. I got in touch with Monoprice support and was connected with Katrina B. I was so glad. She was able to help me and walk me through all the issues I was having. The cables are working better than I expected and am very happy. I hope all your support personnel are as qualified and understand as Katrina is. I will not think twice about using any of your products in the future. Thank you.
