HDMI(High Definition Multimedia Interface) error is one of the most common issues people face on their devices. It can be caused by various things, such as a faulty cable, a BIOS setting, or even a poorly designed TV.
If you’re experiencing an HDMI error and can’t seem to fix it, it may be worth getting a new television or checking to see if there are any known issues with your HDMI cables.
Before We Discuss The HDMI Error Then, We Must Know About HDMI:
HDMI is a high-definition multimedia interface that combines video and audio into a single digital interface.
HDMI is used with versatile digital disc (DVD) players, digital television (DTV) players, set-top boxes, and other audiovisual devices. HDMI provides a high-quality digital video and audio experience.
What Does The HDMI Error Mean?
If you’re having problems with your video or audio, it may be caused by High-bandwidth Digital Content Protection (HDCP) encryption.
HDMI / HDCP handshaking issues occur when the source doesn’t accept the keys from HDMI Distribution equipment. This can be a problem with your display, cables, or devices.
Fixing The HDMI Error Problem:
If you have an HDMI error, there are a few things you can do to fix the problem:
- Check all the connections between your devices to ensure they are secure.
- Restart your devices and try again.
- Try changing the HDMI channel inputs on your display.
If that doesn’t work, try using a different HDMI cable.
Additionally, it’s always a good idea to check the obvious things, like whether or not the Source device (e.g., DVD / BluRay player) is switched on.
If you’re still having issues, try changing HDMI channel inputs on your display – there may be an issue with either the EDID or HDCP ‘handshake’.
Finally, If the problem persists, you may need to replace your HDMI cable.

What Should You Do If The HDMI Error Remains Unresolved?
If you followed the steps in Technique 1 and the HDMI error still won’t go away, you may need to experiment with other options.
On your television, you should now test and implement several inputs. One option is to try using another audio output device on your computer. Another option is to use a different input on your television.
If the HDMI error remains unresolved, the best thing to do is contact your manufacturer or retailer. They may be able to help you troubleshoot the problem or replace the product.
A Brief Consultation On HDCP:
HDCP stands for High-Bandwidth Digital Content Protection. Its system protects digital content as it travels across connections like HDMI, DVI, or DisplayPort.
HDCP handshakes between two devices establish a secure connection before any content is passed between them.
HDCP is a type of digital copy protection developed by Intel Corporation to prevent digital audio and video content copying as it travels across connections.
HDCP works by encrypting the content that is being transmitted with a key that only authorized devices have.
This prevents unauthorized devices from being able to access and copy the content.
HDCP has been adopted by many major digital content providers and is now used by most Blu-ray players, game consoles, and set-top boxes.
The Most Common Types Of HDCP:
There are several types of HDCP, but the most common are Type A 1.4 and Type B 2.2. Both are used to protect digital content from unauthorized copying, but they differ in how they do so.
Type A uses a simple cryptographic key to encrypt the data, while Type B uses a more complex system that includes authentication and key exchange.
Selecting The Correct Output From The Television Menu:
There are a few things to consider when choosing which HDMI output to use on your television. The first is what resolution you want to use.
If you have a 4K television, you will want to use the HDMI 2.2 port. This port can handle resolutions up to 4K.
The next thing to consider is what refresh rate you want to use. If you want to use a higher refresh rate, you will want to use the HDMI 4 port.
This port can handle resolutions up to 1080p at a higher refresh rate. The last thing to consider is what features you want to use. If you want to use features like 3D or HDR, you will want to use
Check To See If Your Tv Has The Most Recent Firmware:
If you have an HDMI-connected TV, it’s important to check if your firmware is up-to-date.
Firmware updates can improve picture quality and sound quality and add new features to your TV.
To check your firmware version, go to your TV’s Settings menu and look for the ‘About’ section.
From there, you should be able to see what version you have and whether or not there’s an update available.
Why Does HDMI Have Sound But No Picture?
There are a few reasons your HDMI connection might have sound but no picture. The first thing to check is that your HDMI cable is correctly plugged in to your TV and device.
If it is plugged in correctly, the next thing to check is your TV’s HDMI input settings. If the settings are set to ‘auto detect,’ change it to ‘PC’ or ‘Computer.’ If you still don’t see a picture, try restarting your device.
In conclusion, HDMI error is a common problem preventing users from connecting their devices to their TVs.
If you experience this issue, it is recommended that you connect your TV to an external DisplayPort or DisplayPort cable to allow for proper video playback.
