| DisplayPort 1.3 | Up to 5120 x 2880 (5K) |
| DisplayPort 2.0 | Up to 8K (7680 x 4320) at 60Hz (uncompressed), limited availability of DP 2.0 devices |
So, Which One Should You Choose?
Now that we’ve explored the pros and cons of each display connection, it’s time to make a decision. If you want to achieve 144Hz at a resolution higher than 1080p or 1440p, DisplayPort is the clear winner.
However, if you’re limited to 1080p or 1440p resolutions or want to use an HDMI connection for other reasons (such as compatibility with your display or device), you can still achieve 144Hz using HDMI.
Additionally, consider the following factors:
- Graphics Card Support: Make sure your graphics card supports your chosen display connection. Some graphics cards have limited DisplayPort capabilities or may require a DisplayPort adapter.
- Display Compatibility: Verify that your display supports your chosen display connection and refresh rate. Some displays may have limited HDMI capabilities or require a firmware update to achieve 144Hz.
- Cable Quality: Use a high-quality cable to ensure you’re getting the best possible signal. Cheap, low-quality cables can degrade your video signal and cause issues with your display connection.
- Other Features: Consider other features such as adaptive-sync technology (G-Sync or FreeSync) and color accuracy. While not directly related to 144Hz, these features can enhance your gaming experience.
Conclusion
When it comes to 144Hz, DisplayPort is the best-suited display connection, especially for resolutions higher than 1080p or 1440p. However, HDMI can still be a viable option if you’re limited to these resolutions or have specific compatibility requirements.
Ultimately, the decision comes down to your individual needs and equipment. By understanding the strengths and weaknesses of each display connection, you can make an informed choice and unlock the full potential of your 144Hz display.
