No worries, as plenty of people, face this issue frequently. With some speedy approaches, you can start working

In this article, I will explain how you can get rid of this annoying HDMI issue. Let’s dive into it.

What are the Reasons HDMI Signal is Not Working?

High-Definition Multimedia Interface aka HDMI is a blessing for its transferring capability of both audio & video signals through a single cable only. Though HDMI’s only competitor Display Port(DP) provides additional bandwidth support, most HDTV or smart TV use HDMI over DP for their output connector.hdmi-signal-is-not-working

HDMI use HDCP (High-bandwidth Digital Content Protection) encryption, which works like an anti-piracy tool to stop sharing original content to unauthorized gadgets. If you want to enjoy these types of content on unrecognized devices, there is a huge chance of experiencing the issue.

Besides this, people also overlook some silly mistakes like a loose connection or forgetting to turn on source devices like PC, consoles, or media players.

Here are some obvious reasons for HDMI not giving a signal to the output device:

  • Loose Connection: One of the main but often ignored reasons is having a connection which is not fastened enough to pass a signal.loose-connection
  • Switched Off Source Device: Once I forgot to turn on my game console. As a result, I was getting the no signal sign.switched-off
  • Wrong Plugged-in Port: If your CPU doesn’t have an iGPU & you plugged in the HDMI cable into the motherboard’s port, this issue will occur for the lack of display adapter.wrong-plugged-in-port
  • Faulty Graphics Card Driver: If your GPU driver gets bugged or corrupted, you get such type of display issue.

No HDMI connection is a very common issue that can be fixed easily. To save you from the hassle, I collected the most effective solutions. Before approaching the fixes, a heads-up to turn on your source & output devices.

Here are the ways how to resolve the no display signal from device platform:

1. Re plug HDMI Cable

Before proceeding to a more methodical approach, make sure you have tightened all of your cables strongly enough. To rule out a loose connection, plug out & then re-plug the HDMI cable.

Also, try to plug HDMI cable one by one into the device rather than plug all cables at once.

Check if this basic approach helps to get rid of the trouble. If the quick remedy doesn’t help, follow the next solution.

Making changes in the boot sequence is another great way to eliminate the issue.

In simple words, when you are watching TV & then you want to play some games with a console, you need to change to the HDMI option from TV with remote. Or else it will not detect the console.

Likewise, from your monitor’s on-screen settings, you have to choose the correct HDMI option (HDMI-1 or HDMI-2) depending on your monitor model.

4. Change HDMI Ports

Sometimes an HDMI port can get damaged. Most HDTVs, smart TVs, or monitors include multiple HDMI ports. So plug out the cable from the current slot & plug it into another extra slot.

This should solve your problem & the display should be back on business. However, if you are still getting no signal from your device, it’s time to go technical approach.

5. Reinstall GPU Driver

One of my friends was non-tech savvy. He didn’t maintain his PC properly. As a result, a few days ago his HDMI cable failed to signal the monitor randomly, which made him panic. So I went to his house & tested the basic steps, but nothing worked.reinstall-gpu-driver

Later, I figured out that he didn’t update his GPU driver for ages, which caused him this random no-signal error. So I updated his graphics driver & the issue never got back.

Before reinstalling, download your specific GPU driver from the manufacturer’s website & remember the location where you saved the file.

Here are the processes to update your graphics driver:

  • Press Windows + X key on your keyboard.
  • Click on Device Manager.
  • Find Display adapters and expand that.
  • Right-click on your GPU name & left -click on Uninstall device.
  • Click on Uninstall & wait for the procedure.
  • Go to the location where you saved your updated GPU driver & install the file.
  • Reboot the system.

6. Set Proper Resolution

Incorrect higher system resolution can often lead to no HDMI signal. For example, a 1080p monitor supports up to 1920×1080 resolution naively. But if you want to run 2560×1440 resolution on this monitor, you will get no signal. Because it is out of the monitor’s display range.

Here are the processes to properly set your monitor resolution:

  • Right-click in the blank space on the desktop.
  • Click on Display settings.
  • Find Display resolution & select your native resolution.

7. Check for Monitor Firmware Updates

Sporadically, monitor manufacturers publish firmware updates for their monitors. If all the mentioned solutions don’t work, you can try to check if there is any firmware update available for your monitor. If you find any, it is recommended to download & install the update.check-for-monitor-firmware-updates
