Comprehensive comparison of DisplayPort and HDMI: features, advantages, and drawbacks.
Introduction
DisplayPort and HDMI are the two most common video outputs used to connect monitors, TVs, and projectors. Though they serve similar purposes, key differences may influence your choice.
Bandwidth and Resolution
DisplayPort 1.4 supports up to 8K at 60 Hz, while HDMI 2.1 can reach 10K at 120 Hz. DisplayPort is favored in professional monitors for its reliable data transfer.
Multiple Display Support
DisplayPort supports daisy chaining, allowing multiple monitors to connect through one port. HDMI lacks this capability.
Audio and Control
Both interfaces transmit audio, but HDMI supports CEC (Consumer Electronics Control), enabling control of multiple devices with one remote.
Use Cases
HDMI dominates home use — TVs, gaming consoles, Blu-ray players. DisplayPort is preferred by gamers and professionals who value high refresh rates and support for G-Sync/FreeSync.
Conclusion
If you need compatibility and ease of use with home devices, go with HDMI. For high-performance setups, DisplayPort is the better choice.
