Silkland Certified HDMI 2.1 Cable, [4K@240Hz 144Hz 120Hz, 8K@60Hz] 1440P Ultra High Speed HDMI Cable 48Gbps (Upgrade Braided), HDR10+, eARC, HDCP 2.3, Compatible for Xbox/PS5/PS4/Roku TV-6.6ft

This cable is thick. I am so glad it is thick and feels so heavy. It means there is just more. And whether that is quality or not remains to be seen. I have a 15ft run from the laptop next to my couch to the TV. I run the cable along the wall with as gentle of a bend as I can for the corner. This cable does not bend but you should not be bending HDMI cables in the first place. The cable is indeed certified. comes in a huge back with the QR code. It plugs in snugly. Not too tight and not loose at all. I fired up my laptop as the other cables just black screened when the refresh rate is set to 120Hz. One even shocked me. Fantastic. This cable worked great. The picture looks clean and if it's pumping 4K HDR 120Hz with 5.1 audio then I give this a pass. Now for longevity I don't know but it feels like a quality cable. I won't be moving the cable at all so it will just be up to the quality and manufacturing process. Overall, I'm really happy so far. I will update as time passes. Remember people. HDMI cables are not meant to be bent. There are like 12 copper wires paired and twisted around each other. The longer the cable the thicker the cable has to be. Imagine twisted pairs of wires being bent. You will break one or weaken on or two without knowing. The cable being thick is great. Go to goodwill if you want thin HDMI cords that can only pump 1080p. 4K and longer runs needs the certification and thick wires.

Works great. Brightness could use some work, but I don’t know if that’s due to the device or the cable.

Worked fior me. However I had to contact TCL support to get my Visio soundbar to work with my 75in TCL.

Excellent

I recently built a new home theater using 8 Klipsch speakers, a Denon AV receiver, and a Samsung 85 inch QLED TV. Everything looks and sounds amazing. However, the eARC channel between the TV and the AV receiver would not work correctly. I initially tried 3 different brand new HDMI cables from various manufacturers. All 3 of the cables "claim" to be certified HDMI 2.1 with ethernet, and will run 8k video and eARC. However, in reality none of the 3 HDMI cables would work correctly. Either the TV could not detect the AV receiver, or when it did the sound would cut out intermittently on the left and right channels when a connection was actually made. Also, the highest video resolution I could get was 1080p @ 120hz. I tried doing all of the TV/receiver resets, power down, and unplug and remove the HDMI cable tricks, and nothing would fix the HDMI eARC connection issues. All I could get was 1080p @ 120hz resolution and sound through the AV receiver only, unless I used the internal TV speakers when watching OTA antenna signals. That's not very good sounding, if you know what I mean.I initially thought, so much for having eARC and high resolution capabilities, and I resorted to using a digital optical sound cable between the TV and AV receiver for about 2 weeks. This worked fine for OTA TV sound, but I still had no eARC or HDMI control between the AV receiver and the connected peripheral devices.After 2 weeks of this "minor inconvenience," I figured what the heck, let's try one more HDMI cable brand. That's when I purchased this 6.6 foot Silkland HDMI cable. As soon as Amazon delivered this Silkland HDMI cable, I unpacked it and plugged it in between the TV and AV receiver. Wow, what an immediate difference. As soon as I turned eARC and HDMI control back on in the AV receiver, the TV and receiver communicated, and the eARC connection was completed. I now have perfect eARC functionality, 4k @ 120hz video, and total HDMI control of all of the peripheral devices. This Silkland HDMI cable works so well that I purchased 2 more Silkland HDMI cables to use to connect the Roku Ultra and Sony Blu-Ray player with. The turntable is connected to the AV receiver via RCA cables, so no HDMI cable is necessary for that connection.Needless to say, I am very impressed with these Silkland HDMI cables. They actually function as advertised, and do it very well. Honestly, I have not tried viewing anything with 8k resolution yet, so I cannot attest to those claims. However, these Silkland HDMI cables work perfectly for my specific A/V requirements. Just be aware that these are thickly shielded, well made HDMI cables, which makes them a bit stiff if any tight turns need to be made.

Perfect length for what I needed. Used it to connect a Roku to my TV and it improved the image as my old cable was incapable of 4k signal.

Unlike the USB-C to DisplayPort adapter from the same brand, this one works flawlessly. The connection is stable, with no flickering, lag, or signal drops. Build quality feels solid, and it delivers exactly what it promises. If you need a reliable adapter, this is definitely a great choice. Highly recommended!

Worked 180hz 1080p read review for trouble shootingI plugged this into my monitor and was locked at 60hz, I trouble shooted through nvidia control panel, graphics drivers, and other tricks with no luck. It wasnt until i read my monitors manual that it stated it only gives the full refresh rate with DP 1.2 and DVI cables. I then tried this on a different monitor with HDMI 2.1 support and it worked. Also note: in your nvidia control panell, you might not be able to use your native resolution, but mirrored resolutions to get your full refreshed rate. Hope this saved some poor soul some time.
