It can be frustrating when you connect your HP monitor to a computer or other device with an HDMI cable, but the monitor does not detect the input.

With the HDMI input, you can try several things to get your HP monitor working correctly.

HP Monitor Not Detecting HDMI (Fix)

Check the HDMI Cable

The first step is to verify that you are using a working HDMI cable.

Try connecting the cable to another device, like a TV or game console, to see if it works properly.

The cable could be damaged or not fully inserted if it does not work.

Replace the HDMI cable with a new high-speed one you know works correctly.

Verify Source Device Output

Ensure that the HDMI output is enabled by the source device you connect to the HP monitor – such as a laptop, Blu-ray player, etc.

Some laptops require pressing a function key or toggling a setting to activate the HDMI port.

Refer to the device manual for instructions.

Update Drivers and Firmware

Outdated drivers and firmware can sometimes cause connection issues with peripherals like monitors.

For the source device, ensure you have the latest graphics drivers, OS updates, and any firmware updates for the HDMI output.

For the HP monitor, go to the HP Support website and enter your monitor model number to check for a firmware update. Install any updates available.

Change HDMI Port

Connect the cable to a different port if your monitor has multiple HDMI ports.

Use the port labelled HDMI 1, HDMI 2, etc. Make sure the cable is fully inserted into the harbour.

Reset the Monitor

Resetting all settings to the factory defaults can resolve detection issues.

On the HP monitor, press the Menu button to bring up the on-screen display.

Go to Management > Factory Reset. This will reset the settings.

Check Input Source Settings

The monitor may have incorrect input source settings preventing HDMI detection:

  1. Press the Menu button and go to Input Control.
  2. Set Primary Input to HDMI if not already selected.
  3. Go to Input Source and make sure HDMI is set to On.
  4. Press the Source button on the monitor to cycle through the inputs until you get to the HDMI input.

Perform a Power Reset

If the monitor is still not detecting the HDMI input, perform a power reset:

  1. Turn off the monitor and unplug the power cord.
  2. Unplug the HDMI cable from the monitor.
  3. Wait 30 seconds.
  4. Reconnect the HDMI cable, then plug the power cord back in.
  5. Turn on the monitor and check if the HDMI input is detected.

This power cycling can resolve detection issues caused by temporary glitches.

Frequently Asked Questions

Here are some common questions about HP monitors not detecting HDMI inputs:

Ques 1: Why is my HP monitor saying “No Signal” with the HDMI connection?

Ans: This usually means the monitor is not detecting the HDMI input.

Check that the source device has the HDMI output enabled, reseat cable connections, try different cables/ports, and perform a power reset on the monitor.

Ques 2: I connected my laptop to the HP monitor via HDMI, but it’s not detecting it. What should I do?

Ans: Make sure the HDMI output is enabled on your laptop by pressing the function key combo to activate the external display port.

You may need to toggle between mirror and extend display modes. Also, update your laptop’s graphics drivers.

Ques 3: I have an HP gaming monitor that won’t detect my Xbox over HDMI. How can I fix this?

Ans: For game consoles, ensure your Xbox output resolution matches the native resolution of the HP gaming monitor, such as 1080p or 4K.

Try power cycling both the monitor and the console. Also, test different HDMI cables and ports on the monitor.

Ques 4: I get occasional black screens when my HP monitor is connected via HDMI. What’s the problem?

Try reseating both ends of the line or connecting a new HDMI cable between the devices.

Ques 5: How do I get picture-in-picture mode working with HDMI on my HP monitor?

Go to the PIP settings in the on-screen menu and select the HDMI input for the secondary picture-in-picture display. Adjust size and placement as needed.


HP monitors not detecting an HDMI input is a common issue that can usually be resolved.

Ensure cables are fully plugged in, source devices have HDMI output enabled; drivers are updated, ports and cables are functional, and power cycle the monitor.

Change input source settings on the monitor itself to detect the HDMI input. If problems persist, contact HP support for further troubleshooting assistance.
