Which is better, HDMI cable or DP cable?
Sep 09, 2026
There is no absolute superiority. It depends on your device and usage scenario. In simple terms, for computer high-refresh-rate displays, DP cables are preferred; for TVs and game consoles, HDMI cables are preferred.
Which scenario is more suitable for using DP cable?
PC e-sports monitor: If you are using a high-refresh-rate monitor with 2K 240Hz or 4K 144Hz or above, the DP cable can run at full specifications more stably and has lower latency.
Multi-screen office or design: The DP interface supports MST multi-stream transmission technology. With one cable, multiple monitors can be connected in series, reducing the clutter of wires.
Seeking low latency: The DP interface has better native support for G-Sync/FreeSync. When playing competitive games like "CS:VALORANT", the operation response is more responsive.
Which scenario is more suitable for using HDMI cables?
Connecting to a TV or projector: HDMI is the standard interface for TVs and is supported by almost all audio-visual devices. It's plug-and-play and more convenient.
Game console players: The PS5 and Xbox Series X only have HDMI 2.1 interfaces. To achieve a complete 4K@120Hz + HDR experience, an HDMI cable must be used.
Home theater: HDMI 2.1 supports eARC, which enhances the audio return channel. With just one cable, it can transmit lossless audio tracks such as Dolby Atmos. It's simpler to connect to the audio system.
Long-distance transmission: The theoretical transmission distance of HDMI copper cables can reach 5 meters. Beyond this distance, optical HDMI cables can be selected. They are more common and less costly than the DP optical solution.
How to determine which cable to use for your device?
Check the interface label: The back of the monitor or graphics card will indicate "DP" or "HDMI", and match the interface type accordingly.
Check the device specifications: In the monitor menu or on the graphics card's official website, check the highest supported resolution and refresh rate, for example, "DP 1.4 supports 4K@144Hz" while "HDMI 2.0 only supports 4K@60Hz".
Check the cable certification: When purchasing, make sure to recognize the official certification mark. For HDMI, choose "Ultra High Speed" certification, and for DP, choose "VESA Certification" or "DP40/DP80" mark. Avoid buying counterfeit cables.
Pay attention to version differences: The physical interfaces of HDMI 2.0 and 2.1 are the same but the bandwidth is 3 times different. The same applies to DP 1.4 and 2.0. You need to confirm the actual supported version through the device parameters.
