How does HDMI 2.1 differ from HDMI 2.0?

HDMI 2.1 ports offer superior performance to HDMI 2.0 ports. First, it supports higher video resolutions, which is a big difference. In contrast to HDMI 2.0, which can only transmit 4K at 60 frames per second or 8K at 30 frames per second, HDMI 2.1 can transmit 4K at 120 frames per second (fps) or 8K at 60 frames per second (fps). Video content, especially games, can be shown at twice the frame rate with HDMI 2.1.

In games, the PlayStation 5 and Xbox Series X support HDMI 2.1 at frame rates of up to 120 frames per second. HDMI 2.1 also enhances visual quality while improving frame refresh for the best visual experience, according to HDMI.org. Adding Variable Refresh Rate (VRR) to the screen allows for a smooth transition between frames and eliminates any visual tearing or jitter between frames, as it dynamically changes the screen’s refresh rate and synchronizes it with the content frame rate.

According to CNET, HDMI 2.1 can also upscale video resolution to 10K at 120 frames per second. To verify these claims, there is hardly any device available at the moment.

Data transfer over cables must be faster to support HDMI 2.1’s higher resolution and double the number of frames. As a result of HDMI 2.1, the maximum bandwidth is increased from 18 gigabits per second (Gbps) to 48 gigabits per second (Gbps). HDMI.org notes that HDMI 2.1 supports Dynamic HDR, which means that HDR data is adjusted with each frame, as opposed to a static HDR setting for all video content.

HDMI 2.1 also supports HDMI Cable Power, which allows HDMI cables to power devices directly from the TV or output source. HDMI active cables transmit data over long distances without reducing the signal’s capacity. The HDMI 2.0 port requires an additional power supply when using active HDMI cables.

The HDMI 2.1 port requires the following upgrades

Unlike HDMI 2.0, HDMI 2.1 is backwards compatible, which means you can use your old peripherals with a new TV. HDMI 2.1’s shape and size, as well as its port, are the same as HDMI 2.0, so you don’t need to purchase new cables unless you really want to take advantage of HDMI 2.1’s extra features.

Does HDMI 2.1 really need to be implemented? The answer depends on your usage, since quite a few devices support the new standard. Video games and consoles will be the most affected, especially if you have a PlayStation 5 or Xbox Series X console along with a TV capable of 120Hz display. It makes sense to upgrade to HDMI 2.1 if you’re looking to completely revamp your home entertainment system.

HDMI port history

HDMI stands for High-Definition Multimedia Interface, or High-Definition Multimedia Interface. HDMI was first introduced in 2002 by Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson and Toshiba. Motion picture producers, such as Fox, Universal, Warner Bros., and Disney, as well as system operators DirecTV, EchoStar, and CableLabs, support HDMI for digital content protection.

In a nutshell

HDMI 2.1 has a higher bandwidth capacity than HDMI 2.0, which is the main difference. As a result, HDMI 2.1 cables and devices can transmit more data at once, supporting higher resolutions, faster refresh rates, and other features. But upgrading to these ports may reduce the weight of your wallet, because the latest gaming devices, whether PlayStation 5 or Xbox Series X, are priced at $ 500, but you won’t find them at this price even if you find them even, assuming you don’t have to pay for display devices that support the latest port, which costs approximately $650 for a 55-inch version. It’s time for you to make your decision now
