Can You Get 240Hz With HDMI? (Easy, Simple, and Quick Explanation)

Can You Get 240Hz With HDMI

When certain cables, such as HDMI and display port, promote AMD FreeSync technology, non-4K TVs have a difficult time scaling up or down the image quality. When it comes to HDMI, the majority of people are concerned about whether or not the technology will allow them to achieve 240Hz. Is it possible that this will happen?

As a general rule, 240Hz can be obtained via HDMI. Simply connect the monitor to your computer using the connection that came with it, even though it is most likely a display port 1.2 cable that supports 1080p 240Hz. If both your screen and your graphics card have HDMI 2.0 capability, you can run 1080p 240Hz.

A common display connection used in most current monitors, HDMI is the most adaptable and widely used of all the display connectors available. Every contemporary television, monitor, as well as graphics card has this technology. However, not all of them are equally effective at converting light into electrical energy.

HDMI 1.4 is the most widely used standard for screens that are not capable of supporting 4K resolution. It is capable of delivering screen resolutions of up to 2560 x 1600 at 75Hz. Furthermore, it is also capable of supporting 144Hz at 1920 x 1080, which is particularly popular with professional computer gamers.

HDMI 1.3 provides 144Hz at 1080p, although the previous HDMI versions (1.0 to 1.2) have a maximum resolution of 1920 x 1200 at 60 frames per second.

As a result, all current monitors include at minimum HDMI 1.4, which provides multi-channel audio compatibility, the ability to transmit Ethernet traffic, as well as the ability to give greater color depths. It is also capable of supporting 4K resolution, though at a maximum frame rate of 30Hz.

This is where the HDMI 2.0 specification comes into play, which significantly enhances the color depths and smoothness of 4K content by supporting 60Hz. HDMI 2.0 now supports 1440p at 144Hz as well as 1080p at 240Hz . Both versions are compatible with AMD FreeSync.

When it comes to HDR (High Dynamic Range), HDMI 2.0a provides compatibility, while HDMI 2.0b provides compatibility for the more sophisticated HDR10 standard as well as the HLG standards.

Another HDMI version, HDMI 2.1, Brings Dynamic HDR, 4K at 120Hz, and potentially 8K at 120Hz to the table. It makes it possible to use the current connections for dynamic HDR as well as the improved adaptive-sync technology but 48G cables are required for 4K and 8K at 120Hz.

Is there a particular HDMI cable that I need to use for 240Hz?

For 240Hz, the display port is the connection that is much more appropriate. This is because its bandwidth is higher than that of the HDMI 2.0. Therefore, this means that the need for purchasing additional cables is eliminated because the cables that are there are generally enough and offer great quality.

What kind of HDMI cable do you need for 240Hz?

For HDMI, a cable that is required is one which has transfer rates of about 14Gbits/s or more than that. This means that any cable with a minimum refresh rate of 14 Gbit/s or above should suffice (in fact, it should be perfect). Please keep in mind that a computer with high processing capability is required to drive a 240 Hz display.

What is the best way to run 240Hz?

If you would like to run 240Hz on HDMI. the following are things that you need to keep in mind. 

  1. Make certain that you are using an HDMI 2.0 cable.
  2. If an HDMI 2.0 cable is being used, be certain that it is connected to the right HDMI 2.0 port on the computer.
  3. It is important to utilize a good cable that is not damaged when connecting the two devices.
  4. Be certain that you are using the most recent graphic card driver’s version.
  5. Be certain that the graphic card is capable of supporting up to 240Hz.

Do HDMI cables support 240Hz refresh rates?

It’s easy excitement of purchasing the latest high-resolution display or the latest processor or graphics card. However, while creating a gaming PC, many people forget about the wires that connect everything together. In addition, having HDMI cables would be preferable.

Sadly, few are aware of the many HDMI types and their compatibility with high resolutions and refresh rates. We realize — knowing these concepts might be complex. 

To assist you in understanding the fundamental HDMI types and which ones you need if you have a 240Hz display.

What is a refresh rate?

The number of times the monitor changes the display in a second is called the refresh rate. For example, a 240Hz display refreshes the screen 240 times per second.

But bear in mind that this refresh rate shouldn’t be limited to only your display. For example, if you wish to use a 240Hz monitor, your CPU, GPU, and HDMI connections should all support it. You’ll get the lowest common denominator supported by these four computer elements. 

Does HDMI support 240hz?

HDMI is the most versatile display connection available today. Modern TVs, screens, and graphics cards all include it. However, not all are as efficient. So, does HDMI allow 240hz?

Yes! HDMI v2.0 and v2.1 allow 240Hz. In reality, both cables are designed for 1080p @ 240Hz.

HDMI ports send digital data. Because digital data needs have grown far quicker than analog ones, HDMI connections and cables must adapt as well. As a result, multiple versions of HDMI ports are already vital in today’s AV market.

Does HDMI support 4K 240Hz?

In addition to 4K at 240Hz with DSC support, HDMI 2.1 offers incredible bandwidth and many new functions.

Even though the new standard has no direct impact on the typical user today or shortly, new equipment released over the next year and into the next decade will increase the quality of movies, games, and virtual reality.

HDMI vs. DisplayPort vs. DVI vs. VGA 

There are four ways to connect a computer to a TV or monitor: HDMI, DisplayPort, DVI, and VGA. So what’s the best link?

HDMI is the most popular TV connection. It’s usually HDMI, DisplayPort, DVI, or even old-school VGA if you wish to connect a computer to your TV. The optimal cable for your display may be more than what it came with.

Here are the variations.

Except for VGA, all other connectors are digital. So while the pixel resolution potentials fluctuate, the quality does not. In other words, 1,920×1,080/60 through HDMI looks the same as DVI and DisplayPort. So, in terms of visual “quality,” the wires themselves don’t matter. However, a cable with a specified resolution will either function or not work over a certain distance.


HDMI is on all TVs and most computers. It is easy to use, but it also conveys audio. So if you’re connecting a computer to a TV, use HDMI. It will save you time.

But HDMI has limits and isn’t always the best option. So your TV probably has HDMI 1.4 connectors, which support 3,820×2,160 pixels at 30 fps. Unfortunately, a new 4K monitor limits you to 30fps. So 4K at 60fps via HDMI won’t be possible until HDMI 2.0. 

If you need exceptionally high resolutions and framerates, one of these alternative options may be preferable.


DisplayPort supports audio.

DisplayPort is a computer interface. There is just one TV with DisplayPort, so don’t expect further TV adoption. It can do 3,840×2,160 at 60fps with DisplayPort 1.2 and Multi-Stream Transport. There’s no reason not to use DisplayPort to connect a computer to a display. The wires cost about the same as HDMI.


DVI’s visual stream is nearly identical to HDMI’s. But the equipment determines the maximum resolution. For example, single-link cables and hardware can only handle 1,920×1,200, but dual-link can do more.

DVI doesn’t do audio. Then utilize HDMI on your TV. Then, not having speakers on computer monitors isn’t a problem.


The VGA cable is the last resort. It’s rare nowadays and rarely seen on TV. Avoid VGA at all costs. It’s an analog signal capable of high resolutions and frame rates. With today’s LCDs, pixel-perfect images are unlikely; instead, use DVI.

Is 240Hz better than 144Hz for gaming?

The faster, the better. A 240Hz display isn’t necessary for games unless you want to future-proof your machine.

240Hz makes fast-paced games wonderfully fluid. However, remember that moving from 144Hz to 240Hz isn’t as obvious as going from 60Hz to 144Hz. So not only will 240Hz improve your gaming experience, but it will also make you a better gamer.

You don’t need a 240Hz display for games that don’t exceed 144 FPS unless you’re updating your PC as well.

240Hz vs. 144Hz Monitors

In addition to the refresh rate, other factors to consider while shopping for a gaming monitor are the kind of panel, the screen resolution, and the adaptive sync technology.

There are presently no 4K gaming monitors with 240Hz refresh rates, although several 1080p and 1440p models have 240Hz refresh rates.

Not only that, but you must decide if you want a display with variable refresh rates like FreeSync and G-SYNC, motion blur reduction via backlight strobing, or both.

These technologies are available in both 144Hz and 240Hz displays, affecting pricing. There are even 360Hz gaming monitors that give a substantial improvement in motion clarity over 144Hz displays, although not as much as the 240Hz jump.

They are also much more expensive; therefore, they are geared towards professional players. The price difference between 240Hz and 360Hz is unlikely worth the extra quid.

HDMI cable needed for 240Hz? 

This is better than HDMI 2.0 and lower since it has a larger bandwidth limit. However, the cables with 240Hz monitors are generally sufficient and of excellent quality.

DisplayPort is the way to go. You can use HDMI or DisplayPort if your GPU and monitor support HDMI 2.1 ports. So DisplayPort is the best option.

However, the typical PC DisplayPort is 1.4, and the average HDMI is 2.0–2.0b. New Nvidia and AMD GPUs may support HDMI 2.1. The Nvidia RTX 20XX and AMD RX 5XXX series are HDMI 2.0, not 2.1. (4K 60Hz, not 4k 120Hz).


As a general guide, it is possible to obtain 240Hz using HDMI. Simply connect the monitor to your computer using the connection that came with it, although it is most certainly a display port 1.2 cable that supports 1080p 240Hz, If both your screen and your graphics card have HDMI 2.0 capability, you can run 1080p at 240Hz, meaning HDMI 2.0 supports 240Hz. 

You can get 240Hz HDMI. Any HDMI cable is capable of supporting the 240Hz refresh rate. The use of the refresh rate is dependent on the devices that are engaged (For example a High Definition TV, monitor as well as a personal computer). 

You may want to utilize the cables that came with the monitor. HDMI 2.0 may be capable of supporting 1080p at 240Hz. Just make sure that your graphics drivers are also the recent version.
