1. Check Monitor Input Source 

Check Monitor Input Source 

Several input sources are available on many monitors. If your display is set to the wrong input source, you’ll undoubtedly have a “No Signal On Monitor” problem.

The display menu options allow you to inspect (and alter) the monitor’s input source.

  • Simply check for the “input source” choice in the display menu.
  • On the side of some displays, there is also a physical button. You can use this button for cycling through the various settings.
  • Set the input source on your monitor to the proper one. For example, if your device to monitor connection is via HDMI cable, you will select HDMI as the input source.
  • Check if the “No Signal On Monitor” issue is solved.

2. Check The VGA, DVI, HDMI Cables 

Check The VGA, DVI, HDMI Cables 

Begin by meticulously inspecting your monitor cords (VGA, DVI, HDMI). One of the most familiar causes of a monitor indicating a “No Signal On Monitor” issue is a faulty, loose, or misplaced cable.

  • Replug each cord after unplugging it. Make sure they’re all appropriately linked.
  • It may seem self-evident, but you should double-check that each cable is in its proper location.
  • Next, look for any cable damage. Fraying bends and nicks should all be looked for. Because some problems are difficult to spot, running your finger down each cable is also suitable. It will assist you in detecting faults that aren’t immediately apparent.
  • Take a look at the cable ports. Dust and debris might clog the ports and cause the connection to fail.
  • Now, on a different display, test each cable. If you don’t have a spare monitor, ask a buddy if you may borrow theirs.
  • The leading cause of the no signal issue is most likely a cable that doesn’t function with the new display. A new cable will be required.
  • If all of your wires appear to be in good working order, continue to the next option.
  • Check if the “No Signal On Monitor” issue is solved.

3. Reset The Monitor

Resetting the monitor can assist in getting everything back to normal. The resetting procedure usually is straightforward, but it varies depending on the brand of your display. Consult their support page or the monitor’s manual for more information and check if this fixes the No Signal On Monitor Issue issue

  • Turn off your monitor and restart your computer. Turn your monitor back on after the machine has adequately rebooted. A fault in the monitor’s system can sometimes be fixed by shutting it down and turning it back on.
  • Examine the monitor’s settings. The buttons at the bottom control the screen. The display’s position is often changed by four functions: horizontal size, horizontal position, vertical position, and vertical size. Play around with these alternatives to get the settings you like.
  • Try a system restore if tweaking the buttons doesn’t yield the results you want. The Windows Start Menu has a system restore option.
  • Go to “Start,” then “All Programs,” then “Accessories,” “System Tools,” and “System Restore” are the steps to take.
  • Look for the disks that came with your computer when you bought it. There should be recovery disks in them, which, if used, will delete everything on your system and reset it to the exact settings it had when it was first created. Insert the first disk into your computer and follow the instructions.
  • Consult your computer’s manufacturer’s tech support.
  • Check if the “No Signal On Monitor” issue is solved.

Check PC's Hardware 

If none of the preceding ways work, you’ll need to open up your computer and inspect the hardware. Even a single faulty or loose cable component can cause disaster.

Ensure the computer is turned off before you start troubleshooting the hardware. It’s also good to unhook all cords (including the power cord).

  • First, look for any loose cable parts.
  • Examine the case for anything that doesn’t seem right.
  • A component may appear out of place or at an uncomfortable angle.
  • The majority of loose parts, on the other hand, will not be visible. Each part will most likely need to be felt around for or reattached.
  • Check if the “No Signal On Monitor” issue is solved.

Examine Computer’s Hardware

Examine Computer's Hardware.
  • Examine the PC case for any loose components.
  • While locating a loose component is pretty simple, locating a busted part might be more difficult.
  • To figure out which one is broken, you’ll have to replace them.
  • I recommend starting with the graphics card because if it’s loose or damaged, it’s the most likely source of a “no signal” problem.

10. Upgrade Graphics Card Drivers

Upgrade Graphics Card Drivers

The monitor could be the issue. However, most display issues are caused by the graphics card. Your blank screen is most likely the result of a fresh graphics card driver.

Your display may not support some resolutions. Your display may also be able to assist you with solutions that your graphics card does not currently support. It is especially true if your display can display at 4K or 240Hz.

  • If your graphics card is still relatively fresh, you may be able to address the issue by just updating the drivers.
