Does DisplayPort Support 144Hz?

DisplayPort is arguably the most powerful and capable combined audio and video solution for mainstream connections between computers and displays. Whether you're hooking up a high-powered PC to a gaming display, or an external monitor to a laptop, DisplayPort is one of the best ways to do it.

Does DisplayPort support 144Hz?

The simple answer is yes, and at multiple resolutions. Even DisplayPort 1.0 and 1.1 were capable of supporting 144Hz at 1080p resolution when using the first generation high bit rate (HBR) mode. Later DisplayPort connections are even more versatile.

DisplayPort 1.2 can output 1080p and 1440p resolutions at 144Hz, while DisplayPort 1.3 and 1.4 increased bandwidth to manage up to 240Hz at those same resolutions and up to 120Hz at 4K. It can't quite handle 144Hz at that resolution, at least without making sacrifices in chroma subsampling (typically 4:2:2) or using display stream compression (DSC).

The DisplayPort 2.0 standard, ratified in June 2019, will increase bandwidth by up to three times, making it possible to support far higher resolutions (like 10K and 16K) but also faster refresh rates on multiple monitors. It will be capable of two 4K displays at up to 144Hz when using 8bpc. For now, DisplayPort 1.4 cables remain some of the most capable cables on the market.  In the future, once DisplayPort 2.0 becomes more commonplace, you may find fewer people asking Does DisplayPort support 144Hz, and more people asking, Does DisplayPort support 240Hz, as gaming monitors become more and more advanced.

What are the benefits of 144Hz on DisplayPort?

Whether you're using DisplayPort, Mini DisplayPort, or DisplayPort over another cable standard like Thunderbolt 3, you're getting a more capable connection than you would from something like HDMI. Where the most up to date HDMI 2.1 standard does leapfrog a few of the older DisplayPort technologies, DisplayPort 1.4 and especially 2.0, are practically unmatched otherwise.

DisplayPort 1.3 and upwards support up to 144Hz on resolutions as high as 4K, which few monitors yet support – but those that do, use DisplayPort technology that gives you smoother-looking desktop experience on PCs, more fluid in-game visuals with support for higher frame rates, lower input lag for better competitive gaming, and a reduction in flickering, stuttering, and screen tearing. These are all advantages that cannot be found on HDMI when using high refresh rates like 144Hz.

Is DisplayPort mandatory for 144Hz?

No, there are other cables that can handle 144Hz just fine, but they are more limited in their options and supporting resolutions. If you have an older 1080p, 144Hz monitor, you can connect it up to your system using a Dual-Link DVI cable.

At 1440p, your options are a little more limited. HDMI 1.4 can handle it, but only with compression enabled, so we'd recommend HDMI 2.0 or newer if you're looking for a DisplayPort alternative. However, DisplayPort 1.2 or newer will handle that just fine.

If you find yourself stuck with a graphics card or laptop with DisplayPort output, but no compatible port on the display end, don't fret. You can just use a DisplayPort adapter to connect to a variety of inputs including HDMI, DVI, or VGA.

What DisplayPort cable do you need for 144Hz?

One of the biggest advantages of DisplayPort cables delivering 144Hz, or any refresh rate for that matter, is that they are entirely interchangeable. A DisplayPort cable produced for the first-generation will work just as well as one produced for the latest generation of DisplayPort technology today.

Unlike other display technologies, DisplayPort doesn't deliver a better or worse picture depending on the quality or price of your cable. As long as you buy your DisplayPort cable from a reputed retailed or manufacturer, like Cable Matters, you can guarantee a high-quality video and audio stream to your DisplayPort device. A 7.5m active DisplayPort 1.4 cable is recommended for ultimate flexibility without sacrificing performance.  Check out some of Cable Matters’ high-quality DisplayPort 1.4 products:

Best gaming monitors for 144Hz refresh rate

The 144Hz refresh rate is a sweet spot for gaming, which is why you can find numerous forum posts asking, does DisplayPort support 144Hz?  Not only is it a massive improvement over 60Hz gaming, but it is also far more affordable when it comes to dollar cost and system resources than more capable, even-higher refresh rates. Unless you're playing newer esports games that can easily hit 240Hz, 144Hz monitors offer some of the most accessible, high-refresh-rate gaming experiences available today.

If you're looking for a great 144Hz gaming display, the Asus VG279Q is top of the list, with fantastic motion handling, support for FreeSync, black-frame insertion for improved motion resolution, and excellent peak brightness. It is only 1080p, which doesn't make this screen as good as some for prettier games, but it helps reduce system overhead to really take advantage of that higher refresh rate.

At 1440P, you might want to consider the Asus PG279QZ if you're a G-Sync user, or the FreeSync-supporting Samsung C27HG70 if you have an AMD graphics card. If you want something a little smaller or just more affordable, the Viewsonic XG2402 is well worth considering as well. At not far north of $200, it's an excellent solution for anyone wanting a 144Hz DisplayPort gaming monitor.  These types of monitors typically come with 3 ft. cables but if you want a more flexible setup, 144Hz support can be achieved with a quality DisplayPort cable up to 10 ft.

  • hey, is it possible that displayport 1.2 would have limited fps at 1080p@ anything over 60hz.
    I'm tryin to figure out why my FPS seems limited if I go any higher then 60hz.
    I play on an RX 6900xT plugged into a asus PG248Q USING DISPLAYPORT (1.2)
    AND ALSO  a samsung 28'' 4k with HDMI 2.0
    in rocket league 1080p 60hz I get 400+ FPS, but if I turn the hz to the next step 85. i start to lose a lot of FPS. @280hz i barely get 280 ( which is good). i can't figure out why the sudden drop from 400-500 to 240 ish.
    and in overwatch I get like 150fps at 1080p 144hz,  but 4k, same settings, I get like 220fps minimum.
