We encourage you to follow the methods below in order until you encounter a fix that is effective in resolving the issue in your particular situation.

Method 1: Booting in Safe Mode and changing the resolution & refresh rate to allowed values

The most common reason why the “the current input timing is not supported by the monitor display” error occurs is if the monitor’s resolution or refresh rate (or both) is/are set outside the supported rate. Most of the time, this occurs due to manual user intervention, but there are certain 3rd party applications that might do this.

Some affected users have managed to resolve the issue by booting their computer into Safe mode and lowering down the resolution or refresh values. Here’s a quick guide on how to do this:

  1. Insert Windows the installation media and press any key when prompted to boot from it. At the initial screen, click on Repair your computer in the bottom-left corner to open the Windows Recovery Environment screen.
    Click on Repair your Computer
    Click on Repair your Computer

    Note: If you don’t have the installation media, you can force your computer to boot into the Windows Recovery screen by forcing two or three consecutive hard shutdowns. You can do this by holding the Power button when you see the Windows logo coming on the screen.

  2. Once you get to the Recovery menu, go to Troubleshoot > Advanced Options > Startup Settings, then click on Restart.
    Acess the Startup Settings menu
    Access the Startup Settings menu
  3. Your computer will restart and you will see a whole new set of recovery options under Startup Settings. Once you arrive at this menu, press 4 to boot up in Safe mode and wait for the procedure to complete.
    Press 4 to boot into Safe Mode
    Press 4 to boot into Safe Mode
  4. When the startup is complete, press Windows key + R to open up a Run dialog box. Then, type “desk.cpl” and press Enter to open up the Screen Resolution window.
    Run dialog: desk.cpl
    Run dialog: desk.cpl
  5. Once you’re inside the Display screen, change the Resolution and refresh rate to the recommended values. Keep in mind that the refresh rate can’t be modified from here unless your monitor supports multiple refresh frequencies.

    Note: This menu will look different depending on which Windows version you’re using.

  6. Restart your computer and see if your computer is able to boot normally without triggering the “the current input timing is not supported by the monitor display” error.

If you’re still encountering this issue after following the steps above, move down to the next method below.

Method 2: Use a different cable 

If Method 1 was not successful, you might want to start considering the possibility of a hardware issue. Some affected users have discovered that in their case, the culprit was identified to be the connection cable between the PC and the monitor.

If you have one lying around in your house, connect it and see if the “the current input timing is not supported by the monitor display” prompt is still appearing. A good indication that the cable has gone bad is if you have previously noticed any sudden screen flickering or interruptions.

In the event that you decide to buy cable, look for a  shorter but higher quality cable instead of looking at the length.
