HDMI is often used to move your display from a computer to a second monitor or television, as well as from video game consoles to your television, among other things.

However, in order to ensure that this functions effectively, it is critical to ensure that the cables are properly configured otherwise you will get error messages and bugs such as Windows 11 HDMI to TV not working properly.

It is our goal in this article to show you how to quickly and easily resolve a variety of typical issues that you may have when utilizing HDMI connections on your Windows PC. This includes a lack of drivers, outdated OS, dusty cables, and others.

But first, let’s see what the cable’s nomenclature differentiates from one another. Follow along as later we will also talk about wire speeds. Keep up with us!

What do HDMI 1.4, 2.0, and 2.1 mean?

The 1.4 specification was published well than a decade ago, and all HDMI cables are made to at least that level of quality. It was developed to look ahead to 4K and set certain criteria to enable support for it in the future (from 2009) by providing enough bandwidth for 4K video at up to 24 FPS.

The HDMI 2.0 specification was first published in 2013, and later amended into 2.0a and 2.0b versions in 2015 and 2016, respectively. The maximum bandwidth of HDMI cables was increased from 10.2Gbps to 18Gbps as a result of this specification.

Having the capacity to handle 4K video at 60 frames per second with all sorts of high dynamic range helped to solidify 4K support even further, and also established the framework for 8K support as well.

As of 2018, HDMI 2.1 has been released, and it is designed to enable 8K and greater images while providing a maximum bandwidth of 48Gbps. The HDMI 2.1 protocol is capable of supporting 4K and 8K video at frame rates of up to 120 frames per second with plenty of headroom.

If you aren’t planning on purchasing an 8K television anytime soon, the 2.1 standard is mostly essential for high-end gaming, as gaming PCs and the latest game consoles have the capacity to deliver frame rates greater than 60 frames per second in 4K.

These requirements are all crucial for ensuring that media streamers and other devices can transmit and that televisions can receive enough data to perform their functions, but they aren’t all that important for the cables themselves.

What can I do if HDMI port is not working in Windows 11?

1. Clean your HDMI port

Consider performing one of the most basic troubleshooting methods for HDMI issues on Windows 11 before becoming overly concerned: disconnecting and reconnecting the cable.

Before you connect it back in, make sure to manually or, better yet, with bottled air, blow out any dust that has accumulated in the port. In addition, you should visually verify the wire to ensure that it is not damaged.

If this is the case, you should replace the wire, since it is most likely the source of your difficulties. After you’ve completed this, you should reset the cable on both ends. Note that the solution also works for Windows 11 HDMI audio not working errors.

2. Try another HDMI port

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

When you try to connect your Windows 11 PC to HDMI, do you notice that there are two or more HDMI ports available? It’s most likely a sign that you’re using a graphics card and that your cable is plugged into the incorrect connector.

Some computers are equipped with integrated graphics, which contain an HDMI connector that is connected to the motherboard by a ribbon cable. If you have a graphics card, make sure the wire is plugged into the HDMI port on the graphics card rather than the port on the motherboard.

Hopefully, this will resolve the situation. Also, if your GPU has many HDMI ports, try a different one on each of your computers.

3. Update drivers

  1. Press the Windows key + I to open the Settings window then tap on Windows Update followed by Advanced options.update-advanced subnautica not saving settings
  2. Scroll down and navigate to Additional options section then tap on the Optional updates option.optional-update subnautica not saving settings
  3. Now click on the Driver Updates option then select all the updates you are presented with, and lastly, click on the Download & install button.install-update subnautica not saving settings

Although Windows is generally in charge of driver updates, if you encounter difficulty, you can manually check for updates. We strongly advise using a specialist program for automatic scans of outdated drivers such as DriverFix.

  1. Press the Windows key + I to open the Settings window, then click on Windows Update from the left menu presented to you.update-windows windows live photo gallery encountered an error loading wix photoviewer.dll

Which HDMI cable is the fastest?

When it comes to HDMI 1.4 and 2.0, its speed ratings, as specified by the HDMI Forum and the Licensing Administrator, are far more important to consider. They mention speeds in conjunction with their maximum bandwidths, but they do not specify which cables are to be used.

As a result, HDMI wires are classified into one of four speed categories: standard, high speed, premium high speed, and ultra-high speed. Standard HDMI cables are the most common type used.

Standard ones are the most basic and slowest of the cables available. A total of 4.95Gbps is available, which is sufficient to transmit a 1080p signal to your television, but not much more than that.

Even though Standard HDMI cables are hard to come by in stores, they can be found in a bucket somewhere or connected up to an old home entertainment system that hasn’t been updated in five years if you look hard enough. These devices are completely incapable of supporting 4K video.

When it comes to bandwidth, High Speed is more than twice as fast as Standard, with a minimum bandwidth of 10.2Gbps. The vast majority of new HDMI cables you purchase will be High Speed or higher, which means they will be capable of transmitting a 4K signal in most cases.

The problem is that the available bandwidth will only handle 4K24, which is 4K video at a frame rate of 24 frames per second. That’s OK if you only want to view movies on Ultra HD Blu-ray, but if you want to watch streaming TV episodes or play games in 4K at 30 or 60fps, your system won’t be able to keep up.
