TISOFU [Ultra Certified] 8K HDMI Cable 6FT: HDMI 2.1 Cables 48Gbps High Speed Premium Braided Cord 8K@60Hz 4K@120Hz 4K@144Hz HDCP 2.2&2.3 CL3 ARC eARC for HD/HDR/HDTV

Great product worth buying the picture is crisp and clear and you can hear the difference in the sound I got this cord for my 4k tv and I have a Dolby atmos sound bar also and it is compatible with bith and works great no complaints here I even bought another one for my 4k dvd player

I connected this cable to a usb c dongle that supports. HDMI 2.1. That dongle is plugged into my 2021 Macbook Pro with M1 Max. With that dangle and this 10ft HDMI cable I immediately was able to configure the full 5120x1440 resolution with 120 hz and HDR on my Samsung Galaxy Neo G9 51” monitor at the 32:9 screen ratio. It looks aweome!

Picture quality is great & cable feels well put together

Trying to get eArc to work on Sonos Arc and this did it with a Samsung QN90A. Not sure how but it wasn’t working and now it is!

When I connected a new Panasonic 4K player (DP-UB820) to an old 2015 4K LG OLED TV, the player was unable to negotiate a 4K connection. Instead it stepped down to a 1080p feed. I had good quality High Speed HDMI cables, but re-routing and replacing them resulted in intermittent success at 4K. Since I needed at least a 10 foot length, I concluded my existing cabling was marginal. The Tisofu cables solved my problem. I was willing to pay extra for an HDMI 2.1 cable that is certified by HDMI.org via their smartphone app. Note that there are 12 versions of the HDMI spec dating back to 2002, but only 4 cable speeds specified: 4.95 Gbps Standard Speed (HDMI 1.0-1.2a), 10.2 Gbps High Speed (HDMI 1.3-1.4b), 18 Gbps Premium High Speed (HDMI 2.0-2.0b), and 48 Gbps Ultra High Speed (HDMI 2.1-2.1a).

The cable quality is great! Very fast and reliable.

This cord is worth the buy. I couldn’t make out the emblem/icon for Jane, on Avengers, but now i can.

Great product and fast shipping! Works great with my 8k Samsung

I have been using these cables for about a year. We have 5 TVs with Rokus and Blu Ray Players hooked up to each. Two of the TVs are 4K with 4K players and Dolby Atmos soundbars hooked up via eARC. One is a 3D 1080P TV with a Xbox hooked up to play the 3D disc and games along with a 5.1 soundbar hooked via ARC. The rest are 720P or 1080P TVs without sound bars (no ARC HDMI ports). I started using these cables after I bought my first Dolby Atmos soundbar and tried to hook it up using the eARC. I had several cables that claimed to be HDCP 2.2 (non-certified) so I hooked them up and starting having sound issues, like the sound would cut out on the soundbar and the TV speakers would come on then go off and the sound bar would play again or lose the sound all together. I then bought one of these cales because they were certified and when I had contacted the manufacture of the sound bar about the issues they said make sure the cable I was using was HDCP 2.2 certified due to using the CEC to allow the units to connect to each other properly. Once I hooked up the soundbar with this cable the problem went away. I though to myself what else I have I been missing using the other cables so I purchased two more to hook up to my Roku 4K with Dolby Vision and my Sony 4K player to our UHD HDR TV in the living room. I couldnt believe the difference in the sharpness and colors using these cables. I did not tell my wife I had swapped out the old cables to these and the first time she watch the TV with the new cables she accused me of buying a new TV there was so much change in the way the TV looked, Needless to say I have since swapped out all the HDMI cables to these , I will say on the regular 720/1080P TVs we did not see any big change if any change at all but on the 3D we did see a change in the playing actual 3D movies they were sharper and more enjoyable to watch.

Excellent quality come whit the hdmi certified high speed cable mega like
