What Cables Support 144Hz?

What Cables Support 144Hz

Want to have a crisp, clear picture on your 144hz monitor? If so, you’ll want to output video and images to your screen at 144Hz. Content that’s 1080p offers the highest speeds and best clarity available.

But you’ll need more than just a monitor for the content to be clear: you’ll also need the best cable for 144Hz.

1080p vs 1440p Options

There are 1080p and 1440p options available, and while the 1440p will offer a better overall picture, it will require a different cable. A general rule of thumb for each available resolution is:

  • 1080p. Output in 144Hz at 1080p will require you to have a cable that is one of the following:
    • HDMI 1.4+
    • Dual-Link DVI
    • DisplayPort
  • 1440p. Output at 144Hz at 1440p requires the following:
    • HDMI 2.0
    • HDMI 2.1 for 4K at 144Hz
    • DisplayPort 1.2

All of these options do have some exceptions. For example, the HDMI 1.4 with the 1080p recommendation may be limited, depending on the monitor.

best cable for 144hz

There are displays where the HDMI 1.4 can max out at 60Hz or 120Hz. You’ll need to make sure that you consider the limitations of the monitor before purchasing your cable.

The same with DisplayPort for the 1440p monitors.

DisplayPort 1.4 can max out at 120Hz when compression isn’t available, so you may not be able to maximize your output for 144Hz.

If you’ve purchased a high-end monitor (like the ASUS ROG Swift PG27UQ) with the intent of the video being 144Hz, you’ll really need to put a lot of time into choosing the best cable for 144Hz.

VGA or D-Sub Connector

VGA Cable

VGA or D-Sub connectors are found on old monitors, and these cords will not be able to provide the 144Hz rate you desire. Most new graphics cards will no longer feature these ports, instead, they will have newer ports like DVI or HDMI.

Why?

Because these older connectors can only provide a maximum of 75Hz, and the resolution is 1920×1200.

Sure, there is still a place for these cords, and you can use them to run a separate rig, or you can use them for a multi-monitor setup.

DVI Connector – Does DVI Support 144Hz?

DVI Connector

The DVI connector, or digital visual interface, is very common, but what you may not know is that there are several different versions of the DVI connector. You’ll really be looking for the Dual-Link DVI-D port, and this is the port that is able to provide: 1920×1080 at 144Hz.

Otherwise, the other DVI ports will have the same rate as the VGA connectors mentioned earlier.

If you try and move to a higher resolution, even with the Dual-Link, you’ll be limited to 75Hz. You’re stuck with the 1920×1080 resolution.

DisplayPort

Displayport cable

DisplayPort is featured on a lot of gaming monitors. This port will have native support for up to 240Hz at 1080p, but it needs to be DisplayPort 1.2. Native support on the 1.2 is as follows:

  • 240Hz at 1080p
  • 165Hz at 1440p

You can run 4K at 75Hz.

Of course, there have been advancements with the port, too. The 1.2 has since been upgraded with 1.3 and 1.4 options. Both iterations offer more overall bandwidth, and you’ll be able to activate 240Hz at 1440p, 120Hz at 4K and even 30Hz at 8K. Compression allows the 1.4 port to offer higher bandwidth.

Note: Mini-Display ports also have the same bandwidth as their full-size counterparts.

HDMI – Does HDMI Support 144Hz?

HDMI Cable

If you have HDMI ports, you’ll find that most retailers sell HDMI cables. These widely-used cables offer options for televisions, graphics cards and monitors. What’s great is that HDMI 1.4 is able to support 144Hz at 1080p, and 75Hz at 1440p.

Monitor bandwidth should be your main concern here, and the reason is that the monitor may have limited bandwidth.

Even if a monitor is able to offer 144Hz, it will be limited on HDMI 1.4 to just 120Hz. Depending on the monitor, it may be possible to maximize this bandwidth to 144Hz.

You just have to make sure that if there’s an HDMI 1.4 port, the monitor will be able to utilize 144Hz bandwidth. Otherwise, HDMI 2.0, which is highly used anyway, can produce high bandwidth rates.

The HDMI 2.0 can produce 240Hz at 1080p, 144Hz at 1440p and even 4K at 60Hz.

HDMI 2.1 can support 120Hz at 4K UHD, so there are more than enough options available.

When all else fails, you can often find adapters that may be able to help. These adapters will need to hook into a USB port for power (non-powered adapters won’t be powerful enough).

You’ll find adapters that can offer DisplayPort to HDMI and DVI to DisplayPort. But these adapters are often expensive, and in some cases, the adapter doesn’t work as advertised.
