HDMI or DisplayPort for a Gaming Laptop?

The two connectors on a gaming laptop

A gaming laptop connects to an external monitor through a video connector. The two you will see are HDMI and DisplayPort. HDMI is the common connector on TVs and many monitors. DisplayPort is more common on computer monitors and often appears on a laptop as a USB-C port with DisplayPort mode.

Both carry video and audio. The difference is in the maximum resolution and refresh rate each version supports. The version of the connector matters more than the shape. A laptop with HDMI 2.1 can drive a 4K monitor at 144Hz, while an older HDMI 1.4 may only reach 4K at 30Hz. DisplayPort 1.4 can handle 4K at 120Hz, and DisplayPort 2.1 goes higher. For a full guide on connecting an external monitor, see external monitor support.

For gaming, the refresh rate of the external monitor is as important as the resolution. If you play competitive shooters, you want a high refresh rate, and the connector must support it. This article explains which connector to choose based on your play style and monitor. Also check your gaming laptop ports checklist to see what is available.

HDMI versions and what they support

HDMI has gone through several versions. The most common on gaming laptops are HDMI 2.0 and HDMI 2.1. HDMI 2.0 supports up to 4K at 60Hz. HDMI 2.1 supports up to 4K at 144Hz and even 8K at 60Hz. The version is printed in the laptop's specifications.

If your laptop has HDMI 2.1, you can connect to a 4K 144Hz monitor and get the full refresh rate. If it has HDMI 2.0, you are limited to 4K at 60Hz. For 1440p at 144Hz, HDMI 2.0 can handle it, but you may need to use a lower color depth. HDMI 2.1 also supports variable refresh rate, which reduces screen tearing. Learn more about HDMI 2.1 and refresh rate guides.

The monitor's HDMI port also has a version. Both the laptop and the monitor must support the same version to get the highest refresh rate. If the monitor has HDMI 2.0 and the laptop has HDMI 2.1, the connection runs at HDMI 2.0 speeds.

DisplayPort versions and what they support

DisplayPort is less common on TVs but standard on gaming monitors. DisplayPort 1.4 supports up to 4K at 120Hz and 1440p at 240Hz. DisplayPort 2.1 supports up to 4K at 240Hz and 8K at 60Hz. Many gaming laptops do not have a full-size DisplayPort; instead, they offer DisplayPort over USB-C. For a deeper look, see DisplayPort 2.1 on gaming laptops.

USB-C with DisplayPort mode uses the same signal as DisplayPort. You connect a USB-C to DisplayPort cable or adapter. This is common on thin gaming laptops that lack space for a full-size port. The USB-C port must support DisplayPort; not all USB-C ports do. Check the laptop's specifications for the DisplayPort version, as it varies.

DisplayPort also supports variable refresh rate, which is useful for gaming. If your monitor has a high refresh rate, DisplayPort is often the better choice because it supports higher bandwidth. For competitive play, a 240Hz gaming laptop paired with DisplayPort can give you an edge.

Comparing HDMI and DisplayPort for gaming

For gaming, the connector that supports the highest refresh rate at your monitor's resolution is the one to use. If you have a 1440p 240Hz monitor, DisplayPort 1.4 or HDMI 2.1 can drive it. If you have a 4K 144Hz monitor, HDMI 2.1 or DisplayPort 1.4 with DSC can handle it. See our 144Hz gaming laptop picks for compatible models.

DisplayPort tends to have higher bandwidth in its latest versions, which allows higher refresh rates at high resolutions. HDMI 2.1 is comparable, but it is more common on TVs. For a gaming monitor, DisplayPort is often preferred because it is the standard for high refresh rates.

However, the laptop's port is the limiting factor. If your laptop only has HDMI 2.0, you cannot get 4K at 144Hz, even if the monitor supports it. Check the laptop's specifications for the HDMI and DisplayPort versions before buying. For AAA gaming, a gaming laptop for AAA games will often have the latest ports.

If you play competitive shooters, a high refresh rate is important. A 240Hz monitor with DisplayPort or HDMI 2.1 will give you a smooth experience. For slower games, a 60Hz connection is fine, and HDMI 2.0 is sufficient.

USB-C and Thunderbolt as DisplayPort alternatives

Many gaming laptops use USB-C ports that support DisplayPort. This is the same as a DisplayPort connection but through a smaller connector. Thunderbolt 4 ports also support DisplayPort and can drive high-resolution monitors. Learn about USB4 vs Thunderbolt 4 to see the differences.

USB-C with DisplayPort can support the same refresh rates as a full-size DisplayPort, depending on the version. Thunderbolt 4 supports DisplayPort 1.4, which handles 4K at 120Hz. Some laptops have USB-C with DisplayPort 2.1, which supports higher refresh rates.

If your laptop has a USB-C port that supports DisplayPort, you can use a USB-C to DisplayPort cable to connect to a monitor. This is convenient because it reduces cable clutter. Check the laptop's specifications to see if the USB-C port supports DisplayPort and which version. For a clean setup, a portable gaming laptop often has USB-C with DisplayPort.

For gaming, a USB-C to DisplayPort connection is as good as a full-size DisplayPort. It is a good option if your laptop lacks a full-size DisplayPort but has USB-C.

What to pick for your play

The choice between HDMI and DisplayPort depends on your monitor and how you play. If you have a high refresh rate monitor, use the connector that supports the highest refresh rate. DisplayPort is often the best choice for gaming monitors.

If your laptop has both HDMI 2.1 and DisplayPort, use DisplayPort for the highest refresh rate. If it only has HDMI 2.0, you are limited to 60Hz at 4K. For 1440p at 144Hz, HDMI 2.0 can work, but DisplayPort is better. Consider a 144Hz gaming laptop for a balance.

For competitive play, prioritize a high refresh rate. A 240Hz monitor with DisplayPort or HDMI 2.1 will give you an edge. For casual play, a 60Hz connection is fine, and HDMI 2.0 is sufficient. Always match the connector to your monitor's capabilities.

Questions

Is DisplayPort better than HDMI for gaming?

DisplayPort often supports higher refresh rates at high resolutions, making it better for gaming monitors. HDMI 2.1 is comparable, but DisplayPort is more common on gaming monitors.

Can I use a USB-C port for DisplayPort?

Yes, if the USB-C port supports DisplayPort mode. Check the laptop's specifications. USB-C with DisplayPort can drive high refresh rate monitors.

What is the maximum refresh rate for HDMI 2.0?

HDMI 2.0 supports up to 4K at 60Hz. For higher refresh rates, you need HDMI 2.1 or DisplayPort.

Do I need a special cable for high refresh rates?

Yes, the cable must support the bandwidth. For DisplayPort 1.4 or HDMI 2.1, use a cable rated for those versions. A low-quality cable may limit the refresh rate.
