The Monitor Shows “No Signal” Despite the PC Being Turned On: How to Fix the Problem

Desktop PCs might not be as popular as they once were, but still, you can get your job done while using them in a lot of cases. You can easily mount more than just one hard disk/SSD on them, while you can get those components repaired significantly faster than in the case of laptops.

There are plenty of undeniable advantages when it comes to using a desktop PC. But whether we like it or not, such machines will also display errors from time to time, and one of them is the famous “no signal” issue that will show itself even if the PC itself is turned on. Therefore, let’s go ahead and learn how to get rid of it! But first of all, we need to understand why the issue occurs in the first place.

Why is the monitor showing “no signal”?

To summarize, the “no signal” issue kicks in when the monitor is on but it’s not detecting a signal from the rest of the computer. Here’s what can cause the issue:

• Outdated drivers
• Hardware problems
• Loose or damaged cables
• A poorly configured display
• Faulty monitor

How to fix the “no signal” problem

Check the cables

First and foremost, you need to make sure that there’s no issue with those cables triggering the error. Therefore, feel free to check those cables thoroughly. A cable might be placed in the wrong port, loose, or faulty. In all these cases, don’t be surprised if you’re granted the “no signal” error. Feel free to unplug each of the cables and plug them back in, or test them on a different monitor to see if the issue persists.

Reset the monitor

As we said, it may be the monitor itself causing the “no signal” issue. In this case, you just need to reset that monitor to put things back in order again. While there’s no rocket science at all to reset a monitor, the process can vary depending on the manufacturer of your monitor. This means that you should check the support website of the monitor for the right information on how to reset it, or consult the product’s manual.

Check the resolution

The resolution configuration might be the root cause of the problem, which means that you should better check it out a bit. For instance, don’t be surprised if the “no signal” problem occurs if the resolution of your graphics card is set to a higher level than your monitor can handle.

Booting up the monitor in safe mode can allow you to adjust the resolution to the right one. Here’s what you need to do:

1. Head over to the Windows settings menu
2. Go to System, Display, and then search for Display Resolution.
3. Change to the resolution you want.
4. You will have to confirm that you want to keep the display settings through the simple pop up that emerges.

Update the drivers

Outdated drivers can be to blame for the infuriating “no signal” problem, as well as for other software issues. It will obviously be a bit difficult to update your drivers as long as your display doesn’t appear as it should, but that shouldn’t discourage you. You will just have to boot up in safe mode.

Here’s what you need to do to get those drivers updated:

1. Select the Start button.
2. Search for Device Manager and select the option that appears
3. Inspect the options and look for the drivers that need updates.
4. Right-click on the drivers you want to update and select the “update driver” option.

Those are some of the best tips we can give you to solve the “no signal” issue with the monitor. Optionally, you can inspect the hardware components of your PC and check for loose or faulty pieces.
