Do I need HDMI 2.1 for 1440p 120Hz?

To answer the question directly, you don’t absolutely need HDMI 2.1 to reach 120Hz or even 144Hz refresh rates at 1440p resolution, but it is highly recommended for supporting both high refresh rates and high resolution at the same time, especially if you’re looking for the best possible gaming experience with Variable Refresh Rate (VRR) and other advanced features. The HDMI 2.0 standard can already support up to 165 FPS at QHD (2K) gaming without any problem, but HDMI 2.1 offers more bandwidth and features that can enhance your gaming experience.
