We stream all our TV content through Roku's. On our main 1 year old Samsung and 1 year old Roku Ultra we had begun to have buffering issues. I did some research and decided to upgrade my HDMI cable from the Roku Ultra to my TV. I also needed a slightly longer HDMI cable as we were rearranging our Roku Ultra. Ultimately I decided on the Arisen cable. Not only did it solve my relocating problem but it has solved my buffering problem. Keep in mind that my old HDMI cable was a good quality but it was about 4 years old. Upgrading the HDMI has definitely made a huge difference. Very easy to install.

Did exactly what I wanted. Plugged the source end into my RTX 3080, the display end into my LG C3 OLED TV and was able to set the output to 4k, 120Hz, HDR, with G-Sync (VRR) enabled. Pretty incredible from such a thin and light cable at 75 feet in length.

This impressive ARISEN Ultra HD High-Speed HDMI Cable enables the 48Gbps bandwidth and is backward compatible; this is great news for those who have older HDMI devices. The cable also works very well with high-bandwidth features such as uncompressed 8K video with HDR, as well as supporting Dolby Vision, Dolby Atmos, HDCP 2.2 & 2.3, DTS:X, and eARC. It is also forwards compatible, ie. it works well with next-generation technology like Dynamic HDR, VRR, ALLM, QFT, QMS. It boasts exceptionally low EMI (electromagnetic interference), which means that it reduces interference with other wireless devices in your vicinity. It uses a slimmer and more supple cord which makes installation easier and has a reassuring 12-months warranty.

I was buying a new 50 ft HDMI cable to use the ARC function of my new TV which feeds audio back to the receiver. With this cable the audio had a lot of drops. I think the Fiber HDMI cables use copper wire for the ARC function and that it is too small a wire gauge. I bought a different Fiber HDMI cable and same thing with audio drops. I then bought a regular, non-fiber HDMI Ultra cable and ARC worked perfectly. Giving it 3 stars because using just video to the TV worked fine. Will give the same review to the other Fiber cable that dropped audio to keep it fair. The HDMI Ultra cable that worked was less than half the price of this one and is 24 AWG copper: https://www.amazon.com/dp/B01N9BGU7E?psc=1&ref=ppx_yo2_dt_b_product_details

Works as expected for a 4k projector in the theater room. Runs all speeds, resolutions and 3D without any glitches. Ends are good sized for pulling through conduits.
