DisplayPort is a digital video and audio connection widely used in computers, graphics cards, and monitors. While HDMI is the most common standard for televisions and consoles, DisplayPort is usually the best option for PC gaming, high-refresh-rate monitors, design, editing, and multi-monitor setups.

Quick Summary

  • Use DisplayPort for PCs, gaming monitors, high refresh rates, and multiple monitors.
  • Use HDMI for TVs, consoles, projectors, and home cinema.
  • DisplayPort 1.4 is still very common for 4K and gaming monitors.
  • DisplayPort 2.1 is designed for higher bandwidth and superior resolutions/frequencies.
  • DP to HDMI may require an active adapter depending on the case.

DisplayPort vs HDMI: Practical Comparison

Use Case Best Common Option Reason
PC to Gaming Monitor DisplayPort High refresh rate, FreeSync/G-Sync, good GPU support
Console to TV HDMI It's the standard for televisions and consoles
Multiple Office Monitors DisplayPort Can support MST on compatible devices
Soundbar / Home Cinema HDMI ARC/eARC and audiovisual ecosystem

DisplayPort Versions: DP 1.2, 1.4 and 2.1

The DisplayPort version affects resolution, refresh rate, and available bandwidth. You don't always need the highest version, but it's good practice for the cable and equipment to be aligned with the monitor you want to use.

  • DisplayPort 1.2: valid for many 1080p, 1440p, and 4K monitors at 60 Hz.
  • DisplayPort 1.4: very common in gaming monitors; allows higher resolutions and refresh rates, with HDR and DSC on compatible devices.
  • DisplayPort 2.1: designed for very high bandwidth needs, advanced monitors, and future resolutions.

How to choose a DisplayPort cable

1. Check the monitor's resolution and Hz

Connecting a 1080p monitor at 60 Hz is not the same as a 4K monitor at 144 Hz. The higher the resolution and refresh rate, the more important it is to use a good quality cable compatible with the required version.

2. Be careful with length

For video cables, length matters. A cable that is too long or of low quality can cause flickering, image dropouts, or signal loss. For long distances, active cables or specific solutions may be necessary.

3. If going from DisplayPort to HDMI, check if you need an active adapter

A very common question is how to connect a computer with DisplayPort to an HDMI display. In many cases, a simple adapter works, but in others, an active adapter may be needed, especially with certain resolutions, refresh rates, or older equipment.

Tip: if the DisplayPort to HDMI adapter doesn't show an image, it doesn't always mean it's defective. It could be a compatibility issue, resolution, frequency, or active/passive adapter type.

Frequent problems with DisplayPort

Black screen or no signal

  • Check that the cable is properly connected at both ends.
  • Try another port on the graphics card or monitor.
  • Temporarily lower the resolution or refresh rate.
  • Update graphics card drivers.
  • Try a certified or higher quality DisplayPort cable.

Flickering or image dropouts

These are often related to a low-quality cable, excessive length, interference, or a setup that is too demanding for the cable used.

Maximum monitor refresh rate not appearing

Check the DisplayPort version of the monitor, GPU, cable, and operating system settings.

Frequently asked questions about DisplayPort

Does DisplayPort transmit audio?

Yes, DisplayPort can transmit digital video and audio, provided the device and monitor support it.

Is DisplayPort better than HDMI?

It depends on the use. For PCs and monitors, it's usually excellent; for TV, console, and sound, HDMI is often more practical.

Can I connect DisplayPort to HDMI?

Yes, with a compatible cable or adapter. In some cases, you will need an active adapter.

What cable do I need for a 144 Hz monitor?

It depends on the resolution. For 1080p/1440p, a good DP 1.2/1.4 may suffice; for 4K and high refresh rates, carefully check the cable version and quality.

Conclusion

DisplayPort is one of the best connections for getting the maximum performance from a computer monitor. If you are looking for fluidity, high resolution, or a professional setup, choose a cable that matches your monitor and graphics card.
