As technology moves towards HD capabilities with all viewing mediums, including TVs, computers, tablets, and smartphones, having tools that can transfer the data needed for tear-free, crisp and clear images is a must. HDMI cables are designed to act as the highway between digital devices that use high bandwidth for HD signals. Creating a seamless entertainment experience and cutting down on the number of cables and remotes need to run systems, HDMI cables are a must-have for anyone who wants to take full advantage of their HD-capable unit.

Explained by, HD screens, most commonly found with TVs, have a wider screen, faster refresh rate, and more pixels than traditional analog screens. All that extra data needs to be quickly transferred between the cable box, DVD player or gaming console and the screen to deliver the graphics as they were designed to be viewed. HDMI cables transfer the information digitally, eliminating the need for TVs to manually process the power and signal into an analog format. When setting up a BluRay or DVD player, or a gaming console like Xbox or PlayStation, an HDMI cable will ensure that the video’s sound and pixels are quickly transferred from the player to the TV for a smooth viewing and audio experience.

Standard HDMI cables can carry a 1080p high definition signal, which is the most common display for HDTVs. They can also support eight channels of uncompressed audio, which is enough to power a 7.1 surround sound system. While these are features that are must-haves for home entertainment systems, they also work for computer monitors and external speakers, as we as tablets and smartphones.

If you’re setting up a home theater system or want to connect your computer, smartphone or tablet to an HD screen, an HDMI cable is a necessity. Below we’ve included three options that will bring your HD visuals to life.


1. AmazonBasics High-Speed 4K HDMI Cable

The AmazonBasics High-Speed 4K HDMI Cable supports Ethernet, 3D, 4K video and ARC while also connecting multiple devices on the same internet connection.

Pros: Our most affordable option, the AmazonBasics can connect just about any device, including gaming consoles, BluRay players, computers and more to HDTVs. The cable can connect multiple devices to one internet connection without the need for a separate Ethernet cable. The cable supports bandwidth up to18Gbps and is rated CL3 for wall installation.

Cons: Customers reported that they were pleased with the AmazonBasics cable but noted that more expensive HDMI cables will have a longer useful life.

2. BlueRigger Rugged High Speed HDMI Cable

Our longest option at 10 feet, the BlueRigger Rugged High-Speed HDMI Cable is rugged and durable with triple cable shielding and 100 percent pure copper conductors, ideal for a home with pets.

Pros: With added durability thanks to the nylon-braided construction, the BlueRigger supports the latest HDMI standard including 4K, 3D and ARC, with a 600 MHz refresh rate. Like the AmazonBasic, the BlueRigger has a bandwidth up to18Gbps. The BlueRigger is the best option for those looking for a HDMI cable to compete their audio entertainment system, with the cable able to support up to 32 discrete audio channels. BlueRigger products have a lifetime warranty.

Cons: Customers noted that while the nylon braiding adds a protective layer, once the cable is bent in a specific direction it does not easily readjust.

3. Twisted Veins HDMI Cable

The three-pack Twisted Veins HDMI Cable comes with a protective braided jacket and gold-plated contact for a safe and secure cable.

Pros: The Twisted Veins is priced similarly to the AmazonBasics and BlueRigger, but you get three cables in a pack. Like the first two options, the Twisted Veins supports signals of up to 18Gbps bandwidth and delivers 4K and resolution with a 60Hz refresh rate.

Cons: The cables are only three feet long, making it difficult to connect devices that aren’t on top of each other. The cables don’t work with all 4K devices.
