Have you ever stood staring blankly at the back of your computer or TV wondering what the difference is between all those HDMI and DisplayPort connectors? Don‘t worry, you‘re not alone! As display standards evolve rapidly, even tech enthusiasts have trouble keeping the advancements straight. Well, you‘ve come to the right place my friend.
In this epic guide, we‘ll unravel everything you need to know about DisplayPort and HDMI to hook up your devices with confidence…
A Brief History Behind Display Interfaces
Before diving into the DisplayPort vs HDMI debate, it‘s helpful to understand how we got here. Visual interfaces started advancing rapidly in the late 90s to accommodate improving display capabilities and digital connectivity needs…
[More on history and context around VGA, DVI, evolution to DisplayPort and HDMI]So What Exactly Are These Things?
HDMI and DisplayPort are digital audio/video interfaces used to connect computers, game consoles, Blu-ray players, and other devices to monitors, TVs, and displays. They transmit uncompressed video and audio signals over a cable to the display.
Think of DisplayPort as primarily a PC monitor focused standard developed by the Video Electronics Standards Association (VESA). HDMI covers a broader range of consumer electronics devices thanks to backing from the HDMI Forum and universal adoption by television manufacturers.
Breaking Down Key Differences Between DisplayPort and HDMI
Now let‘s compare these standards across some key categories to reveal why each excels in different applications:
Resolutions and Refresh Rates
Early DisplayPorts provided significantly higher resolutions and refresh rates compared to HDMI generations of the same period….

The latest DisplayPort 2.0 boasts an impressive bandwidth of 77.4 Gbps enabling…
HDMI 2.1 matches previous DisplayPort specs with 48 Gbps but still falls short of DP 2.0 allowing…
Audio
Both DisplayPort and HDMI can transmit high bitrate 7.1 channel uncompressed audio…
But only HDMI has built-in support for advanced Dolby Atmos and DTS:X surround sound.
Cables and Connectors
HDMI relies on friction to secure cables rather than DisplayPort‘s locking tabs. This impacts reliability and conductivity over long distances…
Active cables provide longer lengths but availability and pricing favors HDMI.
Gaming and Variable Refresh Rate Support
For gaming applications, DisplayPort has an edge when it comes to delivering tear-free smooth frame rates. Technologies like Nvidia G-Sync and AMD FreeSync use capabilities built into DisplayPort to enable variable refresh rates between GPU and monitor. Recent HDMI generations meet DisplayPort‘s fixed max refresh rates, but VRR is still better optimized through DP.

DisplayPort and HDMI continue leapfrogging each other with new specs as 8K display resolution and high frame rate gaming and VR headsets arrive. Expect HDMI to continue leading in home theater gear while DisplayPort pushes boundaries on the PC side…
Bottom Line Recommendations
Based on the breakdown above, here are some bottom line recommendations on when to use each standard:
Use DisplayPort for:
- PC gaming – especially at high frame rates
- Connecting multiple monitors to one computer
- Variable refresh rate technologies
Choose HDMI for:
- Home theater set ups with AV receiver, Blu-ray player and 4K TV
- Game consoles where you don‘t care about high FPS
- Basic monitor connections without variable refresh rate
Either will work for general PC to monitor connections focused on productivity rather than high FPS gaming.
