HDMI port not working properly in Windows 11? what is this

What do HDMI 1.4, 2.0 and 2.1 mean?

The 1.4 specification was published ten years ago and all HDMI cables are at least that high quality level. It was developed to look ahead to 4K and set certain standards to support it in the future (starting in 2009) by providing enough bandwidth for 4K video at up to 24 FPS.

The HDMI 2.0 specification was first released in 2013 and subsequently revised to 2.0a in 2015 and 2016 and version 2.0b. As a result of this specification, the maximum bandwidth of HDMI cables increased from 10.2Gbps to 18Gbps.

The ability to process a variety of high dynamic range 4K videos at 60 frames per second helps further solidify 4K support while also establishing a framework for 8K support.

As of 2018, HDMI 2.1 has been released and is designed to support 8K and larger images while providing a maximum bandwidth of 48Gbps. The HDMI 2.1 protocol supports 4K and 8K video at up to 120 frames per second with ample headroom.

If you're not planning on buying an 8K TV anytime soon, the 2.1 standard is most important for high-end gaming, as gaming PCs and the latest consoles are capable of delivering 4K frame rates in excess of 60 frames per second.

These requirements are critical to ensuring that media streamers and other devices can transmit and that TVs can receive enough data to perform their functions, but they are not as critical for the cable itself.

What should I do if the HDMI port is not working properly in Windows 11?

1. Clean your HDMI port

Before you worry too much, consider performing one of the most basic troubleshooting methods for HDMI issues on Windows 11: disconnect and reconnect the cable.

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

If this is the case, you should replace the wire as it is most likely the source of the problem you are experiencing. Once you've done this, you should reset the cable on both ends.

2. Try another HDMI port

Have you noticed that there are two or more HDMI ports available when you try to connect your Windows 11 PC to HDMI? This most likely indicates that you are using a graphics card and that your cable is plugged into the wrong connector.

Some computers are equipped with integrated graphics, which includes an HDMI connector that connects to the motherboard via a ribbon cable. If you have a graphics card, make sure you plug the cable into the HDMI port on the graphics card, not the port on the motherboard.

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

3. Update driver

1. Press Windows I key to open the Settings application, and then click ## in the left panel #Windows Update and click Advanced Options.
Scroll down until you find the Additional options section and click
2. Optional updates.

4. Update Windows

1. Press Windows I to open the Settings app and click Windows Update# in the left panel ##.
If you have any new updates to download, click on the
2. Install Now button and wait for the process to complete, otherwise click on the Check for Updates button.

5. Reset your screen resolution

Right-click on your desktop and select
1. Display Settings to open your All settings for the screen, including those connected via HDMI cable.
Now scroll down until you encounter the Scale & layout section and select the recommended resolution from
2. Display resolution.

Which HDMI cable is the fastest?

When it comes to HDMI 1.4 and 2.0, the speed ratings specified by HDMI forums and licensing administrators are much more to consider. They mention speeds and maximum bandwidth, but don't specify which cables to use.

Thus, HDMI cables are classified into one of four speed categories: Standard, High Speed, Ultra High Speed, and Ultra High Speed. Standard HDMI cables are the most commonly used type.

Standard cable is the most basic and slowest of the cables available. There's a total of 4.95Gbps available, which is enough to deliver a 1080p signal to your TV, but nothing more.

Although standard HDMI cables are hard to find in stores, if you look closely, they can be found in a bucket somewhere or connected to an older home entertainment system that hasn't been updated in five years. These devices are completely unable to support 4K video.

In terms of bandwidth, the high speed is more than twice the standard, with the lowest bandwidth being 10.2Gbps. The vast majority of new HDMI cables you buy will be high speed or higher, which means they are capable of carrying a 4K signal in most cases.
