What is DisplayPort?
DisplayPort is a high-speed digital display interface standard designed to connect computers to monitors or home theater equipment, etc. Compared to HDMI, DisplayPort generally provides higher bandwidth support for high-resolution and high-refresh rate displays, while also supporting more display connections (through multi-stream transmission MST technology) and advanced features such as Display Stream Compression (DSC) lossless compression technology. In addition, it can also transmit audio, video, USB and other data, making it an important interface option for modern high-performance display applications.
What is HDMI?
HDMI (High-Definition Multimedia Interface) is a digital video/audio interface technology that allows high-quality video and multi-channel audio data to be transmitted without compression. It was designed to replace older standards such as SCART or RCA and become the industry standard for transmitting uncompressed high-definition video and audio signals between consumer electronic devices. The HDMI interface supports a variety of resolutions, from standard definition to 8K ultra-high definition, and also carries the Consumer Electronics Control (CEC) function, allowing multiple devices to be controlled with a single remote control. In addition, HDMI also supports 3D video, HDR (high dynamic range) content, and advanced audio formats such as Dolby Atmos and DTS:X.
Which is better, DisplayPort or HDMI?
Choosing DisplayPort or HDMI depends on your specific needs:
•Bandwidth and resolution support: DisplayPort generally provides higher bandwidth, supports higher resolution (such as 8K) and faster refresh rate, suitable for professional graphic design, high-end games or multi-screen expansion. Although HDMI has also greatly improved bandwidth in the latest version, DisplayPort may still have a slight advantage in the extreme applications of ultra-high definition and high refresh rate.
•Audio and video integration: HDMI is widely used in consumer electronic devices because it transmits high-quality audio and video signals at the same time, which is very suitable for home theater and general entertainment purposes.
•Compatibility: HDMI is more popular, and most TVs and audio equipment are equipped with HDMI interfaces. In contrast, DisplayPort is more common on PC monitors and professional equipment.
•Scalability and flexibility: DisplayPort supports daisy chain connection of multiple monitors, and can be converted to other signals such as HDMI and DVI through adapters, providing better flexibility. HDMI has similar functions but they are more limited.
•Cost: Generally speaking, HDMI devices and cables are relatively low-cost and easier to obtain, especially in the general consumer market.
To sum up, there is no absolute "better", only the application scenario that is more suitable for you. If you pursue the ultimate display performance and multi-screen expansion capabilities, DisplayPort may be a better choice. If you focus on wide device compatibility and home entertainment, HDMI may be more suitable.
