What Is 144Hz Refresh Rate and How Does HDMI affect it

144Hz means that the screen refreshes at 144 times per second which provides a smooth and clear image quality. It is considered one of the best for gaming since competitive games are very demanding of higher refresh rates.

HDMI stands for High-Definition Multimedia Interface. It is used to transfer high-quality images, videos, and audio through the cable from one device to another. With HDMI the image quality remains mostly intact as the source. Because the transfer rate of the connector is very high.

What Do You Need for HDMI to Run on a 144Hz 1440p Monitor

Clarity and speed are the two things gamers want the most from the games they are playing. So, the hardware they use needs to be up to the point where they can enjoy the gameplay without any issues.

To run games at 144Hz and 1440p resolution, you will need HDMI 2.0 compatible monitor and a supported graphics card or console. And if want to go beyond, you can go for the latest HDMI 2.1 which can support up to 60Hz at 8K, and 144Hz at 4K UHD. But again, you’ll need the devices where HDMI 2.1 is supported.

The HDMI connector has become more popular over the years due to its capability of running high resolution with a high refresh rate. Thanks to its backward compatibility, a 144Hz HDMI 2.1 cable can connect to HDMI 1.3, 1.4, or 2.0 HDMI ports. It also supports the same features and bandwidth as the video sources port.

HDMI 2.1 changed the standard by supporting all the new ultra-high bandwidth and data rates. However, to run 144Hz at 1440p, HDMI 1.4 is enough as it provides the same quality for gaming, video editing, rendering, and other high-performance tasks at 1440p and 144Hz refresh rate.
