Can HDMI Support 3440×1440 Resolution?

Yes, HDMI CAN support 3440×1440 resolution. However, you need to have the right HDMI port as well as the right cable in order to support it. Hence, whether can HDMI support 3440×1440 or not depends upon a few factors.

You see there are different version of HDMI port as well as different speeds the HDMI cables are rated at.

You need to make sure that your display device such as the monitor as well as the source device such as the computer, supports the right ports and the version of HDMI.

In the following text I will talk in detail about HDMI as well as its support for the UWQHD resolution i.e 3440×1440.

What is 3440×1440 Resolution?

3440×1440 is also referred to as the UWQHD or Ultra Wide Quad High Definition resolution.

Displays conforming to this resolution have a 21:9 aspect ratio as compared to the 16:9 aspect ratio of the normal widescreen displays.

This resolution is often found on premium grade monitors often intended for gaming or for professional editing work.

As far as professional work goes, this resolution is preferred by video editors as it gives them an excellent wide view of their timeline and the workspace.

Is 3440×1440 4K?

No, UWQHD resolution is NOT the same as 4k. 4K UHD has a resolution of 3840 x 2160. Real 4k has a resolution of 4096 x 2160.

So Can HDMI Support 3440×1440 Resolution?

The short answer to this query is Yes, HDMI CAN support this resolution if you have the compatible version.

How well the resolution is supported depends upon the version of the HDMI port though.

There are different versions of the HDMI ports. The most common HDMI port is the HDMI 1.4. But the best HDMI port at the moment is HDMI 2.1.

The table above shows the different HDMI versions and the maximum resolution and refresh rate they can support.

HDMI 1.4 can support upto 4K resolution. Since 3440×1440 is lower than 4K, HDMI 1.4 supports it too.

However, HDMI 1.4 CANNOT support 3440×1440 at full 60Hz refresh rate! This is because HDMI 1.4 simply does not have enough bandwidth.

HDM1 1.4 can support the typical 1920×1080 at 120 Hz. However, with 3440×1440 resolution, you would be lucky to get a consistent refresh rate of 50 Hz with HDMI 1.4.

As such, in order to support 3440×1440 at at least 60 Hz refresh rate, you will need to have HDMI 2.0 at least.

HDMI 2.0 is generally found on relatively newer PCs. While dedicated graphics cards have been featuring HDMI 2.0 for a long time, HDMI ports on laptops or desktop motherboard I/O panel commonly adhere to HDMI 1.4.

So long story short, while even the basic HDMI 1.4 can support 3440×1440, you will need to have HDMI 2.0 in order to support this resolution at the respectable 60 Hz refresh rate.

Does HDMI Support 3440×1440 at 100 Hz or 120 Hz or 144Hz Refresh Rate?

That depends upon whether you have the HDMI 1.4, HDMI 2.0 or HDMI 2.1

HDMI 1.4 has a max bandwidth of 10.2 Gbps (8.16 Gbps effective). HDMI 2.0 has a max bandwidth of 18 Gbps (14.40 Gbps effective).

Here I would like to point you to two popular online calculators which you can use to test how much data your monitor would generate and thus if an HDMI port will be able to support it.

So basically with an 8 bit color depth, 3440×1440 display would generate:

  • 76 Gbps at 100Hz
  • 46 Gbps at 120 Hz
  • 88 Gbps at 144Hz

Hence you will need to have at least an HDMI 2.0 for supporting 3440×1440 at 100 Hz and will need an HDMI 2.1 for supporting 120 or 144 Hz refresh rate.

However, take note that this is without HDR enabled. With HDR enabled, each pixel takes 10 or 12 bits (depending upon the HDR version you have).

With HDR enabled and with higher the color bit depth of the monitor, the more data rate the video interface will generate and thus may require a newer HDMI version.

Both the Source and the Display Need to Have the Compatible HDMI Port

In order to make the 3440×1440 resolution work on HDMI with 60 Hz or more, then you need to have at least an HDMI 2.0 port, not just on the monitor, but also on the source (i.e PC / laptop).

You cannot have HDMI 2.0 input port on the monitor and connect it to HDMI 1.4 output on your PC and expect 3440×1440 resolution to work at 60 Hz.

The HDMI 1.4 will essentially be the bottleneck here.

You Also Need to Have the Right Cable?

Depending upon the refresh rate and color depth of your monitor, you would need to choose the right type of HDMI cable as well.

Normal gaming monitors typically have a color depth of 8 (16 million colors). If you have professional ultra-wide screen monitor intended for editing work, then there it could have a color depth of 10 bit (1 billion colors) or even 12 bit.

So basically, the higher the color depth and the higher the refresh rate you seek to achieve with the monitors, the more robust an HDMI cable you need.

As such there are different standard of HDMI cables. Each cable type carries a certification for the speed it is designed for.

These include:

  • Standard HDMI: Your average run-of-the-mill HDMI cable for 720P or 1080P screens.
  • High Speed: These have a max bandwidth of 10.2 Gbps. Great for upto 4K resolution @ 30 Hz refresh rate.
  • Premium High Speed: Great for upto 4k @ 60Hz, HDR and High Color Depth. Have bandwidth of 18 Gbps max.
  • Ultra High Speed: Great for Upto 8K @ 60 Hz or 4K @120Hz with high color depth. Have max bandwidth of 48 Gbps.

The more advanced certification a cable carries the more expensive it would be naturally.

Premium Certified HDMI Cable

For 3440×1440, I would recommend that you go for cable with the Premium High Speed certification. As this can ensure that you can maintain 60 Hz or more refresh rate at high resolutions.

The best part about these cables is that they are designed to support monitors with a high color bit depth.

What Other Ports Support 3440×1440 Resolution?

DP 1.2 is one of the most popular port that is used to connect displays with higher than FHD resolution. Therefore, in case if you are missing an HDMI 1.4 but if you have a DP 1.2 port, then you can give it a try.

DP 1.2 can support upto 4K resolution at 60Hz.

Other ports that support 3440×1440 at 60Hz or beyond are the newer iteration of HDMI such as HDMI 2.1 as well as the newer iteration of Display Port such as DP 1.3, DP 1.4, DP 2.0.

Can VGA and DVI Port Support 3440×1440?

No, both the VGA and the DVI ports simply do not support UWQHD resolution. They do not have the sufficient bandwidth.

VGA supports a maximum of 2048×1536 (QXGA) resolution, whereas DVI supports a maximum of 2560×1600 resolution.

Final Words

Long story short, the answer to the question “Can HDMI Support 3440×1440 resolution?” is a yes. However, you will need to have at least an HDMI 2.0 on both your PC and on your monitor to support this resolution at 60Hz refresh rate.
