DisplayPort: what it is and when to choose it over HDMI
DisplayPort is a digital video and audio connection widely used in computers, graphics cards, and monitors. While HDMI is the most common standard for TVs and consoles, DisplayPort is often 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/refresh rates.
- DP to HDMI may require an active adapter depending on the case.
Choose your DisplayPort cable in 30 seconds
Start with the resolution, refresh rate and distance. Then confirm whether both devices use DisplayPort or whether you need to convert the signal:
- 1080p, 1440p or 4K at 60 Hz: DisplayPort 1.2 covers most compatible office and gaming monitors. View DisplayPort 1.2 cables in several lengths.
- 4K, HDR or high refresh rates: choose DisplayPort 1.4 when your monitor and graphics card support it. View the DisplayPort 1.4 cable.
- DisplayPort 2.0 or 2.1 devices: for higher-bandwidth setups with compatible hardware. View the DisplayPort 2.0/2.1 cable.
- Distances from 10 to 40 metres: use fibre optic cable to maintain the signal over long installations. View the fibre optic DisplayPort 1.4 cable.
- DisplayPort PC to HDMI display: check the conversion direction and resolution before buying. View the DisplayPort to HDMI adapter cable.

DisplayPort vs HDMI: Practical Comparison
| Usage | Best Standard Option | Reason |
|---|---|---|
| PC to gaming monitor | DisplayPort | High refresh rate, FreeSync/G-Sync, good GPU support |
| Console to TV | HDMI | It is the standard for TVs and consoles |
| Multiple office monitors | DisplayPort | Can support MST on compatible equipment |
| Soundbar / home cinema | HDMI | ARC/eARC and audiovisual ecosystem |

DisplayPort Versions: DP 1.2, 1.4, and 2.1
The DisplayPort version affects the available resolution, refresh rate, and bandwidth. You don't always need the latest version, but it's important that the cable and equipment are aligned with the monitor you want to use.
- DisplayPort 1.2: suitable for many 1080p, 1440p, and 4K 60 Hz monitors.
- DisplayPort 1.4: very common in gaming monitors; allows higher resolutions and refresh rates, with HDR and DSC on compatible equipment.
- 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 60 Hz monitor is not the same as a 4K 144 Hz monitor. 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 poor quality can cause flickering, image dropouts, or signal loss. For long distances, it may be necessary to use active cables or specific solutions.
3. If you're going from DisplayPort to HDMI, check if you need an active adapter.
A 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 necessary, especially with certain resolutions, refresh rates, or older equipment.
From DisplayPort to another display: what to use in each case
- DP to HDMI in a single cable: the DisplayPort to HDMI 8K 60 Hz adapter cable connects the GPU directly to the monitor or TV without intermediate adapters.
- You already have an HDMI cable: the DisplayPort 1.2 male to HDMI female adapter allows you to reuse it.
- The monitor only has DVI: the DisplayPort 1.2 to DVI-D (24+1) cable solves the connection with monitors and projectors older than HDMI.
Common DisplayPort Problems
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 low-quality cables, excessive length, interference, or a configuration 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 often excellent; for TVs, consoles, and audio, HDMI is usually more practical.
Can I connect DisplayPort to HDMI?
Yes, with a DP to HDMI adapter cable or a DP to HDMI female adapter. In some cases, you'll 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 might suffice; for 4K and high refresh rates, carefully check the cable's version and quality.
Conclusion
DisplayPort is one of the best connections to get the most out of a computer monitor. If you're looking for fluidity, high resolution, or a professional setup, choose a cable that matches your monitor and graphics card.
