What is the difference between HDMI standards and which one is best for 4K TVs?
The primary difference between HDMI standards, such as HDMI 1.4, 2.0, and 2.1, lies in the amount of bandwidth they support and the features they offer. For 4K TVs, HDMI 2.0 is generally the minimum standard required as it supports 4K resolution at 60Hz. However, if you want to take advantage of features like HDR (High Dynamic Range) and higher refresh rates or variable refresh rates, HDMI 2.1 is the preferred choice.
HDMI 2.1 offers up to 48 Gbps bandwidth, enabling it to support 8K resolution and other advanced features such as eARC (enhanced Audio Return Channel) and FreeSync. Keep in mind that both your TV and the source device (like a gaming console or Blu-ray player) need to support HDMI 2.1 to fully utilize its capabilities. If you have a standard 4K TV, an HDMI 2.0 cable may suffice, but investing in a 2.1 cable could provide future-proofing and enhanced performance.
Do I need an expensive HDMI cable for my 4K TV?
Not necessarily. While there are high-priced HDMI cables that boast superior build quality and advanced features, many moderately priced options perform just as well for 4K video transmission.
