    A decent 8K capable cable with 90s looks

    I was able to use this cable in a home entertainment setup where my high refresh rate TV required a high bandwidth connection for proper 4:2:2 color and high refresh (180Hz) 4K connections. I lack an 8K TV to test at higher resolutions but with the bandwidth demonstrated by the connection scenario I put this through, I believe this cable could handle anything. These RocketFish products are very high performance oriented, but my only criticism of the cable would be its industrial design. It seems like something out of late 90s/Early 00s Monster - From the electronic-store-of-old aesthetic. It harkens back to the days where gold plated contacts and advanced looking cable with silver molded ends would fetch a higher premium for the “cool” vibe. I was worried when I got this that I was getting a white-labeled knockoff of one of those cheap wannabe products due to this design. In reality, the cable connected everything I threw at it. Despite its gaudy look, it handled both my TV and a gaming PC I tested with and provided full bandwidth connections with no issues. I personally wish for a version with more understated, professional styling in black on black, but for the money, this is my new standard cabinet cable to future-proof my home AV setup.

    8k Ultra High Speed HDMI CABLE

    The Rocketfish Ultra High Speed HDMI CABLE was easy to set up. Unplugged my 4k cable and replaced it with the 8k cable. First want to mention the quality of the cable. Made of excellent materials and appears to be very sturdy. In addition to this, my tv was able to immediately go into a different view. Meaning the quality of the picture immediate changed upon viewing movies, videos, and shows. There was a cleaner and crisper look while viewing. The audio was great and could tell it was enhanced. I do agree with the box that it came in that the cable does provide a higher quality video, bandwidth, and nice color contrast. It was compatible with the hdmi port that is in my bluray, in addition to the current tv that I'm using. So far all is good. I would recommend this product to others. The mere fact that the cable was easy to install, and immediately saw results while viewing sports, movies, and more. Would recommend. So far no cons to the cable. My favorite part of installing this cable was the fact that when viewing the screen, the colors were brought more to life. Thank you for the opportunity to review this product. It was my pleasure.

    Great Build, Overpriced, and Minimal Impact on Exp

    The Rocketfish 8K HDMI cable boasts excellent build quality, making it feel durable and premium right out of the box. The connectors are solid, and the cable itself feels well-insulated, with a sleek design that screams high quality. It's a future-proof cable, supporting 8K resolution and the latest in HDMI technology, making it technically suitable for the most demanding setups. However, despite its impressive specifications, the high price tag is hard to justify. For gamers or TV enthusiasts, the actual improvement in picture or gaming performance is almost negligible. When using the cable with a 4K or even 8K TV, there’s little to no noticeable difference in image quality or refresh rate compared to far less expensive alternatives. This makes it difficult to recommend unless you’re focused solely on having the most robust hardware available. In short, while the Rocketfish 8K HDMI cable is undoubtedly a high-quality product, it doesn't significantly enhance the viewing or gaming experience—and at its price point, it feels like overkill for most users. If you’re looking for a premium build and future-proofing, it might be worth considering, but for everyday use, there are more cost-effective options that perform just as well.

    I recently purchased a top end LG OLED and bought an HDMI cable reccomened from a friend...It was ok. Knowing the tv that I got I knew I could find something else that would make a difference. I researched cables and this one kept coming up. After reading consistent reviews I bought and so glad I did, definitely noticed a difference, stop thinking about it and buy it - completely worth it!

    Literally makes a huge difference, I use it to connect my high end PC to a Plasma Panasonic TV from 2010, the image is so good it looks 4K, when playing games on that TV it no longer lags like my previous HDMI cable, super smooth, image is unreal and when watching videos with nvidia RTX super rssolution enabled, you will be blown away. I cant believe this is a 1080P TV.
