Methods to Fix DisplayPort to HDMI Not Working

If your computer has a graphics card installed, it probably has a DisplayPort connector for output. This is not compatible with the HDMI ports offered by most older monitors.


To solve this problem, you can use a DisplayPort to HDMI cable or adapter. There are several recommended fixes that you should try if you encounter such an issue: 

Fix 1: Check the DisplayPort and HDMI

When you are using the adapter and see ‘No Signal’ on your monitor, then one of the possible reasons could be a loose connection of the HDMI cable to the adapter or on the DisplayPort interface.

To fix this, you are recommended to plug out the HDMI cable and plug it into the adapter again. Also, make sure the HDMI cable connected to the PC is also tight.

Try to use the same HDMI adapter on another monitor and see if you are facing the same issue. If not, there is an issue with the current system’s HDMI port. You need to get it fixed.

Fix 2:Enable the HDMI Input Manually

  • Firstly, make sure you have connected the DisplayPort properly to the HDMI adapter.
  • Now, press any of the physical control buttons present on your monitor side or below the panel.
  • Click on the Menu icon.
  • Use the arrows present on the monitor and navigate to the ‘Display’ option.
  • Now, select the ‘Input’ option and then select the ‘HDMI’ option, which is present under the input.
  • Now, select ‘OK’ and apply the changes.

Fix 4: Check for the Adapter Compatibility

Sometimes the DisplayPort and HDMI cable are not compatible with each other. Apart from the shape and size of the adapter, even the technology also plays a key role.

If the technology in the HDMI port and the DisplayPort is not compatible, then the signals will not be converted into the required format.


Fix 5: Power Cycle

In case none of the above-mentioned methods are working, then try to power cycle the adapter. You can do that by following the steps mentioned below:

  • Firstly, turn off your computer.
  • Now, turn off the monitor as well.
  • Unplug your monitor and the computer and wait for at least 5 minutes.
  • Plug the computer as well as the monitor.
  • Now, turn on the system and connect to the monitor with the help of an adapter.

This should fix the ‘DisplayPort to HDMI not working’ issue.

Fix 6: Remove all the Cables

In case the monitor has any input cables connected to it, then remove them. Since many input signals are being sent to the monitor at once, there might be an issue in detecting the proper signal.

Only HDMI cable should be connected from the monitor to the system.
