HDMI 2.1 Graphics Card: What You Need To Know About The New HDMI Update

The Sony PS5 and Microsoft Xbox Series X next-generation gaming consoles, which use HDMI 2.1 technology to connect to a suitable monitor, have made ultra-high 8K resolutions a reality for console players.

With the introduction of the Nvidia HDMI 2.1 enabled GeForce RTX Series 30 and AMD Radeon 6000 series, PC gamers now have access to the newest HDMI upgrade. Both of these devices enable ultra-high resolutions and refresh rates, ushering in a new visual revolution in PC gaming that will continue for years.


This post from Bestgaming tips will go over HDMI 2.1 and its capabilities, as well as what it implies for PC gamers in the future.


What is a Gaming Graphics Card?

The graphics processing unit (GPU), also known as the graphics card, is a computer component that receives data from the central processing unit (CPU) about the contents of a scene, such as the positions and actions of the characters and their surroundings, and renders it into a series of pictures (frames) that you eventually see onscreen as moving video. The GPU handles the majority of the processing, especially at higher resolutions and refresh rates.


What is HDMI 2.1 and what does it mean?

HDMI 2.1 Graphics Card

The HDMI 2.1 specification is the most recent major upgrade to the HDMI specification, and it represents a considerable advancement over the previous version. Its most notable feature is a significant increase in bandwidth capacity, which is currently up to 48 Gbps. When combined with a suitable HDMI 2.1 graphics card and other audiovisual source and display devices, this unlocks a wealth of new possibilities.

The 2.1 specification enables 8K Ultra HD video resolutions, as well as the 10K cinematic format with a larger aspect ratio. HDMI 2.1 technology allows for higher refresh rates, such as 8K@60Hz and 4K up to 120Hz. High dynamic range (HDR) video compatibility and the BT.2020 broad color gamut offer more accurate color reproduction and contrast range, and HDMI 2.1 capabilities add Dynamic HDR support to this. This allows the display to change the HDR color tone mapping on a frame-by-frame basis, delivering the best possible image in all sorts of situations throughout a program.

HDMI 2.1 also provides several unique capabilities for gaming. Variable Refresh Rate is one of the most interesting ones (VRR). VRR permits a GPU to send frames to the display as soon as they’re available, which varies depending on the scene’s complexity. Previously, refresh rates were set and restricted at 60Hz, which might cause stuttering and “frame tearing” in the image. Even with the most demanding games and variable frame rates, VRR efficiently syncs the monitor’s refresh rate with that of the game and GPU, resulting in ultra-smooth video output. With its Auto Low Latency Mode (ALLM) and Quick Frame Transport (QFT) capabilities, HDMI 2.1 also helps to decrease display input lag (latency) and power consumption.


Graphics Cards and HDMI 2.1 Features

While the RTX 30 series and its flagship RTX 3090 were the first GPUs to offer Nvidia HDMI 2.1-enabled features, AMD was not far behind. Their Radeon RX 6000 series is the pinnacle GPU for AMD’s RDNA architecture’s newest HDMI technology upgrade. This is the same technology found in the PS5 and Xbox Series X GPUs, which both support HDMI 2.1 and up to 8K visual quality.

The Nvidia RTX 3080 and AMD Radeon RX 6800 were the first graphics cards to support HDMI 2.1, as well as the first to do real-time ray tracing. They’re strong 4K GPUs that can provide up to 8K resolutions with lightweight games, although at lower refresh rates. Both the Nvidia RTX 3090 and the Radeon RX 6900 XT are more powerful predecessors and flagship models for premium 8K performance.

Using some of the advancements that come with HDMI 2.1— such as 8K resolution— is still far from becoming popular, but it’s anticipated to become so in the next couple of years unless you’re gaming with higher resolutions on a high-end PC or next-gen gaming console. But don’t overlook the immediate advantages of gaming features like VRR, ALLM, and 4K@120.

Indeed, HDMI 2.1 is only the tip of the iceberg in terms of what’s conceivable. The level of media, gaming, and video material that this present HDMI standard can provide in the near future will be amazing to behold.
