OLED, which is still considered the premier display technology today, is the calling card of LG as one of the best TV brands, so you know that you'll be getting a top-quality TV with the LG B2 OLED 4K TV. With a 65-inch screen featuring 4K Ultra HD resolution for sharp details and lifelike colors, and powered by LG's a7 Gen5 AI Processor 4K that adjusts picture and sound for the best possible viewing experience, the LG B2 OLED 4K TV will transform your living room into your personal cinema. The OLED TV also runs on LG's webOS 22, so you'll never run out of things to watch through all of the popular streaming services. If you don't own a 4K UHD TV and you don't plan on buying one any time soon, a standard HDMI cable is probably all you need. It supports HD video in both 720p and 1080i resolutions. We've seen 1080p work with standard HDMI cables, but it's not guaranteed. You can use these regular HDMI cables with DVD players, Blu-ray players, game consoles, streaming media players, and even AV receivers and soundbars. Just keep in mind, if you ever decide to venture beyond the realm of HD, you may need something faster.

Despite efforts on the part of some manufacturers to label their cables as HDMI 2.0 or HDMI 2.1, what differentiates one HDMI cord from another isn't the HDMI version. That version number (1, 1.4, 2.0, 2.1, etc.) describes the capabilities of your hardware — from OLED TVs and soundbars to AV receivers, etc. — not your HDMI cables. If you bought your TV or any other piece of AV equipment in the last three or four years, Premium High Speed is the way to go. However, there are features such as variable refresh rate and eARC as well as 4K video at 120Hz which also require an HDMI 2.1 cable. The PS5, Xbox Series X and certain LG 4K OLED TVs support HDMI 2.1, but you’ll only benefit from getting a cable that supports the latest standard if you have both a console and TV that support those features. MHL cables: Many modern TVs allow you to connect your smartphone or tablet using an MHL (Mobile High Definition Link) cable plugged in the phone and then connected via the TV's HDMI. This allows you to share content such as videos or photos on the larger screen, and it charges your device at the same time.

These cables tend to be a bit pricier than those that support HDMI 2.0 or lower, but that, unfortunately, comes with having the latest and greatest tech. While the design and construction of the cable might not make any difference to your image or sound quality (as long as it works properly), it will make it more robust and reliable, or affect how easy it is to connect your screen and source devices. In the past, most experts would have said that either an HDMI cable works or it doesn’t. Unlike analog cables, where the signal quality can degrade from excellent to poor and have a corresponding effect on video or audio, HDMI is a digital cable — and ones and zeroes don’t have quality. They either make it from the source device (like a Blu-ray player) to the destination device (a TV), or they do not. Occasionally, if there is a problem with the signal path (usually caused by a cable run that’s too long), you’ll see “sparkles” on the TV screen. This means that some of the ones and zeroes aren’t making it across the gap. The solution is almost always to replace your HDMI cable with a shorter one. Its braided cable is a cut above the typical heat shrink tubing you'll find on more affordable options, mainly because it stands up to significantly more wear and tear. You won't have to worry about frayed wires or a cord that gives up on you at the drop of a hat, and reliability is a price worth paying for.

Although we’ve talked about the standards, it’s worth knowing the version numbers actually apply to devices – TVs and video sources – and not the cables themselves. What really matters is the cable’s speed capacity – look out for anything rated for 18Gbps to keep up with 4K HDR, which should be just about any cable sold as ‘high speed’. That said, there is a relationship between the version of HDMI your devices use and the kind of HDMI cable you should buy. High-definition Multimedia Interface (HDMI) is a video and audio connection used between HD equipment, such as a Blu-ray player, PVR or a Sky HD box, and your television. HDMI 2.1 cables support 48Gbps ‘ultra high speed’ which is intended to support 8K video (and up to 10K), but it’ll be a couple of years at least before there are widespread compatible devices.

HDMI Ultra/1.5

Because of this, we strongly recommend that if you have Dolby Vision or HDR10+ AV equipment, you only buy high-speed HDMI cables that are guaranteed to deliver the full 18Gbps and that you test them thoroughly with Dolby Vision or HDR10+ content before installing them more permanently. HDMI 2.0: With the advent of 4K ultra-high-definition (UHD) TV, a new HDMI 2.0 standard was agreed. HDMI 2.0 brought various improvements, including support for 4K UHD resolution at 60 frames per second (measured in Hz) and the Rec. 2020 colour space. This as vital now that 4K UHD is more widely distributed to televisions. Certified or tested cables have been tested to make sure they work reliably, and that they’ll support the resolutions and gaming/AV features that they should based on their category. Otherwise, there are a few cables with different swivelling or 90-degree connectors that might make it easier to use them with a screen that’s in a constrained space or mounted on a wall. The difference is that a Premium High Speed certified cable has been independently tested to meet the criteria of HDMI.org. We're of the opinion that an HDMI cable either works or does not, but for some people, the added peace of mind that comes with a certification of reliability is worth a few extra dollars. That said, we feel that the Monoprice Certified Premium High Speed HDMI cable is one of the best certified HDMI cables you can buy, and at a good price.
