The graphics cards have been redefining the gaming experience by delivering rich details along with a smooth gameplay.
If you are a hardcore gamer or a professional designer, then the HDMI 2.1 graphics card is the one you should be looking for. While the HDMI 2.0 interface supports resolutions of 4K@60Hz and 8K@30Hz, the HDMI 2.1 offers a significant upgrade by supporting resolutions up to 8K@60Hz and 4K@120Hz. Plus, the HDMI 2.1 interfaces have High Dynamic Range (HDR) video compatibility.
However, the HDMI 2.1 interface is not the only thing you should check before purchasing a graphics card. The graphics card should deliver enough power to the system to access more details in a short time. The processor, RAM size, and the memory speed play the primary role in deciding the graphics card’s performance.
- Graphics Processor: The graphics processor is the most important component in a graphics card that powers the latter. It is similar to what a motherboard is to a computer. It delivers power to the unit to process images and graphics and display them at high resolution. There are not a lot of options when it comes to graphics processors. Nvidia is the industry leader in the development of graphics processors that is closely followed by AMD.
- RAM Size: This RAM is different from the RAM used in the motherboard. The graphics card’s RAM, also known as VRAM or video memory, determines how fast the graphics card processes data. A higher RAM size improves important features such as frame rate, rendering, physics emulation, and texture qualities. We recommend a RAM size of at least 8GB for an immersive experience.
- Memory Speed: Memory speed, also known as clock speed, is measured in GHz or MHz. It determines the latency, frame rate, and input lag. A higher memory speed allows the graphics processor to access the information faster for delivering a more fluid experience. The graphics card should have a memory speed of at least 1 GHz for a decent performance.
Apart from these, there are several other features that determine the performance of graphics cards. You can find a detailed list of such features in the “Buying Guide” section of this article. But, before heading to that, please check out our curated list of the Best HDMI 2.1 Graphics Cards 2021.

Features to Check Before Purchasing the Best HDMI 2.1 Graphics Card
Welcome to the buying guide section of the article. The performance is not the only thing you should check while purchasing a graphics card. You should also check the integrated technologies, supported resolutions, maximum supported devices, and cooling system.
Integrated Technologies
The graphics processors are equipped with different technologies that significantly influence the performance of the graphics card. Nvidia processors come with more advanced technologies compared to AMD processors. Some of the latest technologies integrated with Nvidia processors are Ampere architecture, AI-powered DLSS acceleration, 4th gen Tensor cores and 3rd gen Ray Tracing cores. These technologies improve the frame rates and deliver high visual fidelity
Supported Resolutions
The main purpose of graphics cards is to support high resolutions and provide an impressive picture quality. The latest graphics cards can support resolutions of up to 8K. If you are a pro gamer or a professional image/video editor, then you need to get a graphics card that can support a maximum resolution of at least 4K.
Plus, you should also check the corresponding refresh rate of the supported resolution. High-end graphics cards support 8K resolution at 60 Hz and 4K resolutions at 120 Hz refresh rates. We recommend getting a graphics card that can support at least 4K resolution at 60 Hz refresh rate.
Cooling Unit
The graphics cards have a tendency to overheat just like the motherboards. So, it is imperative the graphics cards are equipped with an efficient cooling system for faster heat dissipation to maintain the temperature. The blades feature unique designs with alternate and reverse spinning technologies to facilitate airflow. Plus, the graphics card also uses copper pipes for maximum heat dissipation.
Number and Standard of HDMI and DisplayPorts
Aside from the HDMI 2.1 port, having DisplayPort can come in quite handy. The DisplayPort 1.4a supports high resolutions just like the HDMI 2.1 port. If you have connected another device to the HDMI port, you can use the DisplayPort to connect the monitor. You should also keep an eye on the number of HDMI and DisplayPort the graphics card has. Having more ports will allow you to connect multiple display devices simultaneously.
Warranty
The graphics cards are susceptible to malfunctions and complete failure. The most common reason for malfunction is dust and debris getting deposited on them. Plus, incorrect installation or physical damage can also lead to malfunctions and failure. The graphics cards come with a maximum warranty period of 5 years. As they are rather expensive components, getting a graphics card backed by at least a 2-year warranty period will help protect your money
Best HDMI 2.1 Graphics Card – FAQs
Ans: HDMI 2.1 itself doesn’t directly improve graphics, but it enables higher bandwidth (48 Gbps) compared to HDMI 2.0 (18 Gbps). This increased bandwidth allows for higher resolutions and frame rates, such as 4K at 120fps or 8K at 60fps, and supports dynamic HDR and a wider color gamut. These features can result in more vibrant, crisper, and clearer images, particularly in gaming and high-definition video content.
Ans: To run games at 4K 144Hz, you need a powerful GPU. The Nvidia RTX 3090, with its 24GB DDR6 VRAM and high boost clock speed, is a suitable choice for this purpose. It shows improved performance over its predecessors and supports real-time ray tracing and DLSS. Another notable option is the RTX 2080 Ti Founders Edition, which also delivers solid performance for 4K gaming at high refresh rates.
Ans: Yes, HDMI 2.1 is capable of supporting 144Hz at 4K. It was the first HDMI standard to support this high refresh rate at such a high resolution. This feature makes HDMI 2.1 a popular choice for gaming and high-definition video on mainstream consumer devices.
Ans: HDMI can be converted to DisplayPort using an active HDMI to DisplayPort adapter. This adapter takes the HDMI input signal and transforms it into a DisplayPort output, allowing HDMI devices to connect to monitors that only have DisplayPort input. However, it’s important to note that not all adapters can handle the full bandwidth of HDMI 2.1, especially for high resolutions and refresh rates like 4K 144Hz.
Ans: HDMI 2.1 requires a compatible port on both the output (source) and input (display) devices to utilize its full potential. This means both the device sending the signal (like a gaming console or PC) and the receiving device (like a TV or monitor) must have HDMI 2.1 ports. While HDMI 2.1 cables are backward compatible with older HDMI standards, you won’t be able to enjoy the full benefits of HDMI 2.1 unless both connected devices support this latest standard.
