DisplayPort and HDMI are two common digital video interface standards, both of which can transmit high-definition video and audio signals. However, there are some differences between them. This article will compare DisplayPort and HDMI from the following aspects in order to better understand their advantages and disadvantages.

1. Resolution and Refresh Rate

Both DisplayPort and HDMI support high resolution and high refresh rate video transmission. However, DisplayPort is even better at this. DisplayPort 1.4 can support 8K resolution and 60Hz refresh rate, while HDMI 2.1 can only support 4K resolution and 120Hz refresh rate. Therefore, if you need to transmit video signals with higher resolution and higher refresh rate, then DisplayPort is a better choice.

2. Multi-monitor support

DisplayPort is the better choice if you need to connect multiple monitors. DisplayPort supports multi-stream transmission technology, which can connect multiple displays through one interface, while HDMI can only connect one display. Therefore, if you need to connect multiple monitors, DisplayPort is the better choice.

3. Audio transmission

Both DisplayPort and HDMI can transmit high-quality audio signals. However, DisplayPort is even better at this. DisplayPort can transmit high-quality lossless audio signals, while HDMI can only transmit lossy audio signals. Therefore, if you need to transmit high-quality audio signals, DisplayPort is a better choice.

4. Scope of application

Both DisplayPort and HDMI can be used to connect devices such as TVs, monitors, laptops, desktops, etc. However, their scope of application is still different. HDMI is better for connecting to TVs and home theater equipment, while DisplayPort is better for connecting to computers and monitors. So if you need to connect your TV and home theater equipment, then HDMI is the better choice.

5. Physical interface

The physical interfaces of DisplayPort and HDMI are also different. DisplayPort has a smaller connector than HDMI, making it better for connecting laptops and mobile devices. The HDMI interface is larger than the DisplayPort interface, so it is more suitable for connecting TVs and home theater equipment. So, if you need to connect your laptop to your mobile device, then DisplayPort is the better choice.

To sum up, both DisplayPort and HDMI have their own advantages and disadvantages. If you need to transmit video signals with higher resolution and higher refresh rate, connect multiple monitors, transmit high-quality audio signals, connect computers and monitors, then DisplayPort is a better choice. If you need to connect your TV and home theater equipment, then HDMI is the better choice.
