Can HDMI do 144hz ? [Can you Get 144hz with HDMI?] The answer is Yes and No

TL;DR

Yes, HDMI can do 144hz but not always. What matters is the monitor resolution and the cable type. For instance, for 1920 × 1080 resolution HMDI 1.0, HDMI 1.1, HDMI 1.2 and HDMI 1.2a won't support 144hz. But, HDMI 1.3–1.4b, HDMI 2.0–2.0b and HDMI 2.1 supports 60, 120, 144 and 240hz.

For 2560 × 1440 (1440p) HDM1, 1.0-1.1, 1.2-1.2a don’t support 60, 75, 120, 144 and 240hz refresh rates. HDMI 1.3-1.4b, 2.0-2.0b and 2.1 cables support 60, 75, 120 and 144 hz. 240hz in this refresh rate is only supported by HDMI 2.0-2.0b and HDMI 2.1.

For 4k resolution (3840 x 2160) 144 and 240hz are only supported by HDMI 2.1.

Summary the only HMDI that can output 144hz in all resolutions, 1080p, 1440p, 4k, 5k and 8k is HDMI 2.1.  


Let's now get deeper.

Clarity and speed is a real catch for gamers. This fact, however, calls one to invest in the best equipment for crystal clear display of images, video, and audio, as many available miss the specifications. For ideal gaming and streaming with a great texture and premium feel, one requires a setup that supports higher speeds of 144hz and above. And that's where connection technologies like HMDI comes  in. But there is a common question i always get, can hdmi do 144hz? That's what we shall explore in this article.

Many monitors have various types of display ports. In this respect, many modern monitors have HDMI ports but are not able to meet the required speed for the best quality images. A 144Hz monitor is a real catch, especially for gamers, as it can display 1080p or 1440p content, but is a demanding task. It will require either a dual-link DVI or Display Port cable as these standards support higher resolutions and refresh rates, but can you get 144 Hz with HDMI


Can HDMI do 144 Hz? / Does hdmi support 144hz

So, let’s find out if really you can get 144 Hz with HDMI and does hdmi support 144hz

Type of HDMI cables

High-quality cables help you avoid power-up, audio and video problems. 144Hz monitors have multiple input ports like Display Port, Dual-link DVI, and HDMI. To display 1080p content at 144Hz, you need to use an HDMI 1.4 cable or a DisplayPort 1.2 cable, which offers native support for 240Hz at 1080p resolution.

The cables recommended for these display frequencies are often DisplayPort or DVI Dual Link cables. The major question is whether HDMI cable is capable of supporting these frequencies, especially 144hz. However, understanding specifications of the HDMI standard is clear that it is capable of transmitting and displaying any video format that the bit rate of the standard allows. The question is how?

The 144hz transmits 20 Gbps of data transfer; hence a good quality cable to ensure a signal is delivered with integrity is necessary. Low-quality cables cause system power-up problems, flickering screen lower refresh rate, and may at times fail to display completely. The correct cable is, therefore, a prerequisite for HDMI 1.3 or higher to display 1080p content at 144Hz.

It is imperative that when you’re acquiring HDMI cables, to ensure that they have passed the Video Electronics Standards Association's (VESA) DisplayPort certification test. Cables that have not passed the DisplayPort certification test, despite not providing 144hz smoothly, could potentially damage a PC, laptop, or monitor.

HDMI 2.0 /2.1

HDMI connection, mainly found on televisions, is also found on monitors, PCs, graphics cards, and laptops. Even if the majority of users are content with 60 Hz screens, gamers are particularly fond of screens with high frequencies, 144 Hz taking the lead.

Whereas other formats are available, there is, however, no trace of a 1920x1080p @ 144Hz format even in the HDMI 2.0 version.

The HDMI standard is a high-level specification, it recommends a certain number of video formats, but it does not impose any of these formats. It is then up to the manufacturers to decide which video formats they want to implement or not in their HDMI interfaces. If you buy a TV with an HDMI 2.0 port, for example, it does not mean that it will be able to handle all the video formats offered in the version of this standard.

To achieve 144hz, theoretically HDMI 1920x1080p signal at 144 Hz requires a bit rate of 10.69 Gbit / s. HDMI Premium High-Speed cables (HDMI 2.0) support a bit rate up to 18 Gbit / s, 120 Hz, or 144Hz with a resolution of 1920x1080p.

As such, you can use HDMI 2.0 to display 144Hz at 1440p, while the HDMI 2.1 supports 144Hz  at 4K.

HDMI 1.3 /1.4

To output 1080p content at 144Hz, you need either a Dual-Link DVI, a DisplayPort, or an HDMI 1.4 or higher cable. It is worth noting that HDMI 1.4 is designed to handle up to 144Hz at 1920×1080. However, not all monitors out there with HDMI 1.4 necessarily do as well since some are limited to 60Hz or 120Hz.

Modern monitors, TVs, and graphics cards feature at least an HDMI 1.4 port that is enough for 144Hz at 1080p. But, there are others that have limited bandwidth over HDMI 1.4, which makes it max out at 120Hz or even at 60Hz.

To achieve 144hz for 144Hz monitors that are limited to 120Hz over HDMI 1.4, some monitor manufacturers utilize custom timing parameters, pixel rates, and other settings to maximize the HDMI 1.4’s bandwidth performance thus getting 144Hz at 1080p. That said, you need to ensure the type of devices you’re buying can achieve the required output.

Type of HDMI Connector

One important consideration when choosing your HDMI connector cable is the type of connector at each end of the cable. HDMI uses five main connector types: Type A, B, C, D, and E, each for different applications. These include the standard connector as well as the mini-HDMI and micro-HDMI. The absence of proper HDMI connector will prohibit 144z on HDMI, even with the compatible HDMI 1.3 and above.

When acquiring HDMI cables, you need to have a careful look at the connectors because purchasing the correct cable saves you from buying an HDMI connector adapter, thus achieving 144hz at no extra cost.

Length of cable

Cable length is an essential consideration as it affects signal quality. Most cables are usually 3 meters long to ensure a smooth display. Longer cables may lead to distorted display because of a poor signal. Atevon High-Speed 18GBps HDMI cable, ivanky DisplayPort Cable to HDMI, and Capshi High-Speed HDMI cable are able to achieve 144hz that are available in the market.

Use of HDMI Adapters

Many computers and TV might not have the same type of connection. For instance, a TV might have an HDMI connection, but a computer has a DisplayPort, making the incompatible. However, this incompatibility can be addressed by the use of an adapter. This is typically a device designed with a DisplayPort connection on one end, and an HDMI connection on the other end. Where for example a 144Hz monitor and graphics card does not support 144Hz over the same port type, an appropriate adapter may be used.

With an HDMI to DP (display) adapter, you can connect a computer with an HDMI port to a monitor with a DisplayPort port. A DisplayPort to HDMI adapter is required for a DisplayPort to a monitor with an HDMI port.

Other available active adapter combinations are (Mini) DisplayPort to HDMI and vice versa, and USB-C to HDMI. For laptops that have only have a USB-C port and a monitor that supports 144Hz over HDMI, you would need a USB-C to HDMI adapter.

It is important to double-check whether your monitor supports 144Hz over the port one is trying to convert before buying an adapter.


Conclusion

One major advantage of HDMI is that it is universal. It is available on millions of devices. Lately, consumer electronics devices like TVs often include support for three or more HDMI ports.

Additionally, TVs and consumer electronics hardware have already started shipping HDMI 2.1 devices. This, therefore, implies that with proper equipment and knowledge, you would enjoy premium view and gaming at 144hz on HDMI.
