Are you tired of the lag and stuttering that comes with playing games or watching fast-paced content on your monitor or TV? Do you want to take your gaming experience to the next level with a refresh rate that’s as smooth as silk? If so, you’re probably wondering if it’s possible to run a 144Hz refresh rate on HDMI.
The Basics of HDMI and Refresh Rates
Before we dive into the world of 144Hz on HDMI, let’s take a step back and understand the basics of HDMI and refresh rates.
HDMI (High-Definition Multimedia Interface) is a digital audio/video interface that connects devices such as Blu-ray players, game consoles, and computers to displays like TVs and monitors. It’s become the standard for connecting devices to displays, offering high-quality audio and video transmission.
A refresh rate, on the other hand, refers to the number of times a display refreshes the image on the screen per second. Measured in Hertz (Hz), a higher refresh rate means a smoother and more responsive visual experience. The most common refresh rates are 60Hz, 120Hz, and 144Hz.
The Limitations of HDMI 1.4 and 2.0
The first version of HDMI, HDMI 1.4, was released in 2009 and supported up to 370 Mbps bandwidth, which allowed for resolutions up to 4K at 30Hz. However, with the increasing demand for higher refresh rates and resolutions, HDMI 2.0 was introduced in 2013, offering up to 18 Gbps bandwidth.
While HDMI 2.0 was a significant improvement, it still had its limitations. For instance, it could only support 144Hz at a resolution of 1080p (1920×1080 pixels). If you wanted to run a higher resolution like 1440p (2560×1440 pixels) or 4K (3840×2160 pixels), you were limited to a refresh rate of 60Hz.
HDMI 2.1: The Game-Changer
The introduction of HDMI 2.1 in 2017 revolutionized the world of display technology. With a bandwidth of up to 48 Gbps, HDMI 2.1 can support resolutions up to 10K at 30Hz, as well as 4K at 120Hz and 5K at 60Hz.
But what about 144Hz? Can HDMI 2.1 handle it? The answer is yes, but with some caveats. HDMI 2.1 can support 144Hz at resolutions up to 4K, but only with certain compression formats like Display Stream Compression (DSC) and chroma subsampling.
Chroma Subsampling: The Key to 144Hz on HDMI
Chroma subsampling is a technique used to reduce the amount of data required to transmit video signals. By sampling the color data at a lower rate than the luminance data, chroma subsampling reduces the bandwidth required to transmit high-resolution and high-refresh-rate content.
There are several types of chroma subsampling, including 4:2:0, 4:2:2, and 4:4:4. The most common one used for 144Hz on HDMI is 4:2:2 chroma subsampling, which reduces the color data to half the resolution of the luminance data.
However, chroma subsampling can affect image quality, especially in scenes with complex textures and colors.
Display Stream Compression (DSC): The Alternative to Chroma Subsampling
Display Stream Compression is a visually lossless compression format that reduces the bandwidth required to transmit video signals without affecting image quality. DSC is supported by HDMI 2.1 and can compress video signals up to 3:1, making it an ideal solution for transmitting high-resolution and high-refresh-rate content.
DSC is a more efficient and visually lossless alternative to chroma subsampling, but it requires compatible hardware and software.

What is 144Hz and how does it affect gaming performance?
144Hz refers to the refresh rate of a monitor, which measures how many times the display updates the image per second. A higher refresh rate like 144Hz can greatly enhance gaming performance by providing a smoother and more responsive experience, especially in fast-paced games. This is because a higher refresh rate can reduce screen tearing and motion blur, making it feel more immersive and engaging.
In addition, a higher refresh rate can also reduce input lag, which is the delay between the time you input a command and the time it’s reflected on the screen. This can be particularly important for competitive gamers who require quick reflexes and precise timing. Overall, running a 144Hz monitor can significantly improve gaming performance and provide a more enjoyable experience.
Can you run 144Hz on HDMI?
The short answer is yes, but it depends on the type of HDMI connection you have. HDMI 2.0, which is the most common type of HDMI connection found on modern devices, has a bandwidth limitation that prevents it from supporting 144Hz at resolutions above 1080p. However, HDMI 2.1, which is a newer standard, has a higher bandwidth and can support 144Hz at resolutions up to 4K.
If you have a device with an HDMI 2.0 port, you may be limited to 120Hz or lower refresh rates, depending on the resolution you’re using. On the other hand, if you have a device with an HDMI 2.1 port, you should be able to run 144Hz at higher resolutions.
