DisplayPort Explained: How It Compares to HDMI for Monitors
Why DisplayPort remains the preferred connection for PC monitors, how its bandwidth and daisy-chaining compare to HDMI, and when each makes more sense.
DisplayPort is a video and audio connection standard that’s remained the preferred connector specifically for PC monitors among enthusiasts and gamers, generally offering marginally higher bandwidth headroom at comparable version numbers than HDMI, along with certain PC-specific features like daisy-chaining multiple monitors that HDMI doesn’t support in the same way.
Why DisplayPort Became the PC Enthusiast Standard
DisplayPort was specifically developed with PC and computer monitor use cases in mind, unlike HDMI, which was originally developed with home theater and consumer electronics devices like televisions, game consoles, and Blu-ray players as its primary target use case, a difference in origin and design priority that’s shaped DisplayPort’s continued strong association with PC gaming monitors and computer displays specifically.
Daisy-Chaining: A Genuinely Useful DisplayPort-Specific Feature
DisplayPort supports Multi-Stream Transport (MST), which allows daisy-chaining multiple monitors together using a single DisplayPort connection from the source computer, with video signal passing from one monitor to the next in the chain, a genuinely convenient feature for multi-monitor setups that reduces cable clutter and required graphics card outputs, a capability that HDMI doesn’t offer in an equivalent, widely-adopted form.
Bandwidth Comparison Between DisplayPort and HDMI
At comparable version generations, DisplayPort has generally offered marginally higher maximum bandwidth than HDMI, translating into support for somewhat higher resolution and refresh rate combinations, though this gap has narrowed considerably with HDMI 2.1’s substantial bandwidth increase, meaning the practical bandwidth difference between current DisplayPort and HDMI versions has become less significant than it was in earlier generations of both standards.
Why Televisions Still Favor HDMI Over DisplayPort
Despite DisplayPort’s PC-focused advantages, televisions have almost universally continued using HDMI rather than DisplayPort, reflecting HDMI’s deeper entrenchment specifically in home theater and consumer electronics ecosystems, including built-in features like HDMI-CEC that allows controlling multiple connected home theater devices with a single remote, a convenience feature ecosystem that DisplayPort was never designed to specifically address in the same way.
When to Choose DisplayPort vs HDMI for a PC Setup
For a PC gaming or productivity monitor setup specifically, DisplayPort generally remains the preferred connection choice when both the graphics card and monitor support it, particularly for multi-monitor daisy-chained configurations or when pursuing the highest possible refresh rates at a given resolution, while HDMI remains the more practical and often necessary choice when connecting a PC to a television or other home theater equipment that lacks DisplayPort connectivity entirely.
Bottom Line
DisplayPort was designed specifically with PC and computer monitor use cases in mind, offering daisy-chaining support and historically marginally higher bandwidth than equivalent HDMI versions, though HDMI 2.1 has narrowed that bandwidth gap considerably. DisplayPort remains the generally preferred choice for PC gaming and multi-monitor setups, while HDMI remains the practical standard for televisions and broader home theater equipment.
