8K HDMI ARC/eARC Cable for Soundbar 6.6FT/2M HDMI 2.1 Cable 48Gbps Ultra High Speed Cable in-Wall Safe, 4K 120Hz, Supports Dynamic HDR, HDCP, Dolby Atmos for Vizio Samsung Bose Sound Bars

Comes in a nice little cardboard box and appears to be of very good quality. Works nicely so far, but just got it.UPDATE: Did some testing with my previous Amazon Basics cable and no comparison. This one has so much better resolution, but it is 2.1.

Can't say I've had this cable very long at all. Pretty disappointing considering how much it cost, but it's already outputting no signal as confirmed by another working HDMI cable I own to the same 2 ports. I've tested this using 2 other devices and it's definitely borked.I'll reach out to the manufacturer to see what I can do about a replacement cable but I have never in my life had a cable break in this manner, and to do so after such a short space of time is infuriating.Update: dropping this to a 1 star, I've tried to reach out to pacroban directly regarding the broken cable after 5 months of barely any use with no contact at all from them. Avoid them/this product, you've been warned!

50ft HDMI Cable - 4k @ 60hz HDR & Dolby Vision! I did not test this cable at 8k or for ARC as I did not need either. After buying and returning three 50 ft 4k HDMI cables that failed on performing to thier listed specifications, I opted for this 8k cable. Using the new Chromecast with Google TV, Yamaha Receiver and Vizio P Series TV. Works flawlessly for 4k @ 60hz HDR and Dolby Vision. Connectors are well made and cable is very thin and easy to conceal. This is a directional cable so pay attention before permanently installing.

Since I needed a new HDMI cable, I was considering the Monoprice DynamicView ($13.99), but 6 ft was their longest and I needed a bit over 8 ft.I came across the Pacroban (10’= $18.50) in my research and it consistently received high marks and ratings. I decided to purchase this cable and I am very pleased with this cable. I will be purchasing more in the future.----------------------------------------------------------------I reviewed numerous articles comparing and ranking the various Ultra-High-Speed HDMI cables. Here is some information from my research if of interest to those considering HDMI cables.Expensive HDMI cables offer no performance advantage compared to less expensive alternatives with similar specifications and less than 25 feet in length. There is absolutely no need to spend an exorbitant amount of money on HDMI cables. HDMI is a digital cable, transmitting 1’s and 0’s, and they either make it from the source device or they do not. Expensive cables can be more rugged and durable with thicker casings, more robust connectors, thicker internal wires, less EM interference, but you must decide for yourself if the difference justifies the expense. It would be hard for me to justify paying over $25, much less hundreds.Speed (Gbps) is the most important consideration when choosing an HDMI cable under 25’ length and must be fast enough for your specific AV equipment, HDMI version, and media sources. At lengths over 25 feet, HDMI cable build and material quality become much more important. For long distances, active HDMI cables, optical HDMI cables, and wireless are options. I’d prefer optical HDMI cable if needing much over 25 feet.HDMI Cable classifications:1. Standard HDMI: up to 5 Gbps; HDMI 1.2a; 720p/ 1080i2. High-speed HDMI: 10 Gbps; HDMI 1.3 to 1.4a; 1080p/60, 4K/30, static HDR10, Not Dolby Vision HDR3. Premium-High-Speed HDMI: 18 Gbps; HDMI 2.0 devices, 4K/60Hz UHD, all types of HDR, ARC.4. Ultra-High-Speed HDMI: 48 Gbps, supports HDMI 2.1 including 10K/8K/4K, eARC, VRR.Uses for HDMI Cable classifications:1. High-Speed HDMI cables (10Gbps) sufficient for HDMI devices less than HDMI 2.0, up to 1080p/60 and 4K/30Hz HD. They are sub-optimal for HDMI 2.0 and 2.1, UHD, HDR10+, Dolby Vision HDR.2. Premium-High-Speed HDMI cables (18Gbps) should be used with HDMI 2.0 devices, Dolby Vision or HDR10+ A/V gear, and is suitable for most current 4k users.3. Ultra-High-Speed HDMI cables (48Gbps) best for devices requiring greater data bandwidth such as Apple 4K TV, true 8K TV with 8K content, HDMI 2.1 devices such as the newest Denon AV receiver, and for Future-proofing. I’m interested in the upcoming X-box Series X which will support 8K content (as will the new Sony PS5).The price for ultra-high-speed cables is not much more than a premium-high-speed HDMI cable, so if you’re needing a new HDMI cable anyway, it may be worth considering an ultra-high-speed cable. This is an excellent Ultra High Speed 8K HDMI 2.1 cable, great value, and I highly recommend.

I found the video quality to be not as good as other 8k cables that I bought. It feels more like a 4k video resolution instead of the 8k as specified
