How to Fix HP Monitor That is Not Detecting HDMI Connection

Connected your PC or laptop to your HP monitor through an HDMI cable but getting a “No signal detected“, “No input signal” or “Input signal not found” error?

The first thing to do is to determine if the port is faulty or not. For that, connect your computer to a different port on your HP monitor.

If the issue persists, reset HDMI connection. Here’s how to do that:

  1. Turn off your monitor and unplug it.
  2. Disconnect all the cables from the monitor.
  3. Press the Power button on the monitor for 10 seconds.
  4. Wait for 1 minute, and then plug it back in and connect HDMI cable.

This will also power cycle your HP monitor.

Switch Input Source

Most HP monitors come with multiple HDMI ports, so you need to select the correct port as the input source in the monitor’s settings.

If your monitor has multiple HDMI ports, note the port number and then open your monitor OSD settings.

Go to Input and then select the right input source.

Check Cables

If you have selected the correct input source and resetting the HDMI cable connection did not work too, inspect the cable.

Check both ends of the HDMI cable for any damages as well as the power cable of your monitor.

If it is damaged, it won’t provide enough power to the monitor to work properly, so change it immediately.

While this may seem strange, but swapping the HDMI cable ends has worked for many users. So give it a try!

Factory Reset your HP Monitor

If none of the above solutions work and your HP monitor is still detecting input via HDMI cable, then try performing a factory reset on your monitor.

To factory reset your HP monitor, do the following:

  1. Turn Off your PC.
  2. Open the On-screen menu on your HP monitor.
  3. Select the Factory Reset option.
  4. Wait for 5 seconds and then turn on your computer.
