DisplayPort offers higher bandwidth and is better for high-refresh-rate gaming and multi-monitor PC setups, while HDMI is the better choice for TVs, home theater audio, and consoles due to its wider device compatibility.
- Using DisplayPort for 4K@144Hz+ gaming on a PC or workstation
- Using HDMI for a TV, console, or home theater system with eARC
- Your cable version matches the resolution and refresh rate you need
- You use an HDMI 1.4 cable and expect 4K above 30Hz
- You try to daisy-chain monitors over HDMI without a hub
- Your GPU or OS does not support DisplayPort MST for multi-monitor chains
Bandwidth and Resolution
Bandwidth is the biggest technical difference. DisplayPort 2.1 delivers up to 80 Gbps, enough for 16K at 60Hz. HDMI 2.1 tops out at 48 Gbps, which handles 8K at 60Hz or 4K at 120Hz. For most users those numbers are overkill, but if you are pushing a high-resolution monitor at a high refresh rate, DisplayPort has more headroom.
Older versions matter here. HDMI 1.4 caps 4K at 30Hz. DisplayPort 1.2 supports 4K at 60Hz. Always check which version your port and cable support before assuming full performance. You can read the official bandwidth figures in the VESA DisplayPort 2.1 specification release.
Multi-Monitor Support
DisplayPort supports Multi-Stream Transport (MST), which lets you daisy-chain multiple monitors from a single port. HDMI has no native equivalent and requires a separate hub or splitter. If you are building a multi-display workstation, DisplayPort is the practical choice provided your GPU and operating system both support MST.
Audio and Home Theater
HDMI includes Audio Return Channel (ARC) and enhanced ARC (eARC), which send audio back from a TV to a soundbar or receiver over the same cable. DisplayPort does not support ARC. For a living room setup with a TV and external speakers, HDMI is the correct connector. HDR10 and Dolby Vision are supported by both standards.
Device Compatibility
HDMI is on virtually every TV, Blu-ray player, streaming stick, and games console. DisplayPort is standard on PC monitors and graphics cards but rare on TVs and consumer electronics. If you are connecting a laptop to a TV, you will almost certainly need HDMI. If you have a USB-C port and need video output, see whether your USB-C port supports video before buying an adapter.
Gaming Considerations
NVIDIA G-SYNC works natively over DisplayPort and has limited HDMI support. AMD FreeSync works on both. If you are using a G-SYNC monitor, DisplayPort is the recommended connection. HDMI 2.1 adds Auto Low Latency Mode (ALLM), which is useful for consoles that trigger game mode on a TV automatically.
Quick Comparison Table
| Setup | Works? | Need | Note |
|---|---|---|---|
| 4K@144Hz PC gaming | Yes | DisplayPort 1.4+ | Preferred over HDMI for high refresh |
| Console to TV | Yes | HDMI 2.0 or 2.1 | HDMI standard on all consoles |
| Daisy-chain monitors | Yes | DisplayPort MST | GPU and OS must support MST |
| TV soundbar eARC | Yes | HDMI 2.1 | DisplayPort cannot do this |
| 4K@30Hz only | Limited | HDMI 1.4 | Upgrade cable for higher refresh |

Bottom line: Choose DisplayPort for PC gaming at high refresh rates and multi-monitor workstations. Choose HDMI for TVs, consoles, and any setup that needs audio return. When in doubt, match your cable version to the resolution and refresh rate your devices actually require.
