It’s football season, and you’re all set to enjoy the game on a big screen with your friends.

But what’s this? As soon as you plug in your HDMI cable you get the “No HDMI Signal” notification. How frustrating!

Don’t fret, because we’ve rounded up some workable solutions for this issue.

However, most people are unaware of the whole idea of HDMI cables and how they work. I mean, they know that it’s a cable that connects to your TV or laptop, but that’s all!

So let’s just take you through the whole concept of HDMI cables, before we explore various ways to fix the “No HDMI Signal” issue from your device.

What is HDMI?

HDMI is an advanced improvised version of audio and video transmission. It transfers high-quality audio and video without any distortion across compatible devices. Most of you must have only experienced HDMI connectivity via a TV or laptop; however, it is also used in:

  • Home theatre systems
  • LED and Smart TVs
  • Network media players
  • Projectors
  • Blu-ray players
  • Car media system
HDMI Cable

And to connect to all these devices, you need high-quality HDMI cables. You can find a variety of long-lasting HDMI cables on Syncwire, a name you can trust!

How Does HDMI Work?

HDMI is developed to ensure high-definition content on the screen. The HDMI port uses a method of encryption called HDCP (High-bandwidth Digital Content Protection). The goal of HDCP is to prevent a signal from being routed elsewhere, so it is essentially an anti-piracy mechanism.

An HDMI cable works based on synchronization. It connects readily as both devices communicate with each other, known as HDMI Handshake. If the embedded encryption in HDMI is not readable the device will not operate.

If your HDMI is not functional, the embedded encryption in HDMI may not be readable, or there might be an issue with either the hardware or the device it’s connected to.

Regardless, we have some solutions for this issue.

How to Fix the “No HDMI Signal” Problem

If you’re receiving the “No HDMI Signal” error when connecting your HDMI cable to a device, you can resolve this issue with the following techniques:

1. Reconnect HDMI

Most of the time, the error occurs due to booting issues with the device. In case, you find such problems simply unplug and reconnect your HDMI cable.

Here’s how:

  • Switch off the device and unplug the HDMI cable.
  • Now plug in the HDMI cable to the device and restart it.
Reconnect HDMI

This solution is merely an underwhelming troubleshoot method to resolve the issue. But in most cases, it comes as a quick remedy.

2. Screen Resolution

If the above solution was not helpful, then another solution is to check the resolution settings of your device.

For this, follow the steps given below:

Screen Resolution
  • Open “Display Settings” of your TV.
  • Go to the “Resolution Settings” and set it to “Auto.”
  • If the problem persists, opt for “Manual Settings” and try choosing different resolutions.

This solution is very helpful to resolve display issues. But if the issue persists, it might be due to a faulty port or HDMI cable. That is why we always recommend using Syncwire® HDMI cables, designed with the latest 2.0 HDMI technology that allows flawless 4K display at shocking 60Hz.

3. Changing Between HDMI Ports

Most of the latest devices come with multiple HDMI ports. You simply can shift to another port and change the source on your device.

Here’s how to go about it:

Changing Between HDMI Ports
  • Unplug the HDMI cable from HDMI-1 port
  • Plug it into the HDMI-2 port
  • Press “Source” on your remote and select HDMI-2

This method works if your port is malfunctioning. The HDMI cables by Syncwire® are made up of gold-plated ports and tin-plated copper wires and are highly recommended.

4. Enable the HDMI Connection Setting

While connecting the Android® phone or tablet to the TV through HDMI cable, make sure the HDMI connection is enabled on your device.

For this:

  • Go to “Settings.”
  • Select “Display.” 
  • Scroll to “HDMI Connections” and enable it.

In case, this solution also goes in vain, you can try the next one.

5. Disconnect All HDMI Sources And Reconnect Them One at a Time

In the case of multiple HDMI, try reconnecting the sources one by one.

For this simply follow the steps:

  • Unplug all HDMI connections
  • Switch of the TV or monitor
  • Now, power on the screens
  • Connect the HDMI cable back in the TV or screen
  • Switch on the device
  • Now repeat the steps for multiple devices

Usually, this method works. If this, or the previously mentioned solutions do not fix your “No HDMI Signal” issue, it’s time to go technical!

6. Update Graphics Card

If nothing works, the next option is to update your graphics card.

Follow these steps to do so:

  • Right-click on the “Windows” button at the bottom and click on “Device Manager.” This will open a new window.
  • Double click on “Display Adapters” to reveal an extended drop-down menu with the name of the graphics card.
  • Right-click on Intel® UHD Graphics and then click on “Update Driver.”
  • A new window will open to update drivers. Click on the search automatically and let the system detect any update if available. This process will take a while.
  • On the detection of any update, you may proceed with the updating process accordingly.
  • Alternatively, you can also pursue the update by browsing your computer system if you already have a driver software saved on your computer system.

If updating the graphics card also doesn’t prove useful, then getting your device checked by a professional would be a good idea.

But there’s one last option that just might solve this issue!

7. Get a Syncwire HDMI Cable

If unplugging and reconnecting your HDMI cable doesn’t work, and adjusting the resolution settings and updating the graphics card also fail, there’s a possibility that your HDMI cable might be faulty. In such a case, as we mentioned earlier, getting an HDMI cable from a trusted brand like Syncwire might be the answer!

They are highly engineered cables developed for smooth video and audio streaming.

Here are some other compelling features:

If that doesn’t convince you, I don’t know what will!
