Is DisplayPort better than HDMI for 144Hz?

DisplayPort is generally considered better than HDMI for achieving a 144Hz refresh rate. While HDMI 2.0 and later versions can support 144Hz at lower resolutions, DisplayPort offers higher bandwidth and better compatibility for high refresh rates and resolutions. DisplayPort also supports adaptive sync technologies like AMD FreeSync and NVIDIA G-Sync, which can further enhance the gaming experience. However, it's important to note that the specific capabilities of a device and its connections should be checked to ensure compatibility and optimal performance.

To get 144Hz, you should ideally use DisplayPort as it's the most capable out of the bunch. Here, DisplayPort 1.0-1.1a is able to output 144Hz at 1080p, while 1.2-1.2a can output 1440p at 144Hz, 1.3 outputs up to 120Hz at 4K, and 1.4 can output 144Hz at 4K using Display Stream Compression (DSC).
