How To Do It

Examine Your Cabling and Power

Before you tear out your graphics card or travel to Amazon to get a new display, thoroughly inspect your PC and monitor to verify there are no cabling or power problems.

This is an easy check to do. Begin by tracing the wiring between your display and PC to confirm that no connections are loose. A faulty HDMI cable, for example, might be preventing your PC’s output from being viewed (and vice versa).

It’s also possible that the display cable is faulty. If you see cable damage or if the cabling is fairly old, replace it with something else. This may occasionally address any issues with your monitor’s display right away.

There might potentially be a power problem preventing your display from operating properly. If your monitor displays a no signal error, you may presume it has power, but if your PC isn’t turned on, you won’t see any errors.

A portable monitor may not offer as much screen space as its desktop counterparts. However, these compact displays definitely give you that additional room you need, whether you’re creating content, gaming, or simply multi-tasking at work, without taking up a whole lot of desk space.

Is the source of the monitor’s input correct?

A no signal error on a display might indicate that your PC monitor is ignoring your PC’s graphics output. This may happen if your monitor’s input source is set to the incorrect device.

Most display monitors have several input ports, such as VGA, HDMI, and DVI. This enables the connection of several devices to the same display. This might be numerous PCs or a PC and a games console, which you could then switch between using the firmware menu or physical controllers on your display.

If this is the case, ensure that the input source on your display is properly configured. If it isn’t, change the source (for example, HDMI or DVI on current PCs) to get your display functioning again.

Examine the Monitor Resolution

A PC monitor has a limited number of display resolutions that it may employ to show the output from your computer. If your PC’s graphics card is set to a display resolution that is more than what your monitor can show, you will most likely get a blank screen or a no signal warning.

Fortunately, resolving a blank monitor screen after altering your display settings is a simple task. Wait 15 seconds if the display abruptly loses resolution after you change the settings—Windows will restore to your old resolution after this time.

If you haven’t modified your display settings in a while, your monitor resolution may have been adjusted automatically. There are workarounds, such as rebooting Windows and booting into Safe Mode to sidestep the problem with a higher resolution.

Drivers for your graphics card need be updated

When a display issue develops, the monitor itself is often the focus of your diagnostic efforts; however, the graphics card that your PC utilizes is frequently the larger cause. If you’re seeing a blank screen on a new monitor, it’s probable that you need to update your graphics card driver.

As previously stated, your PC may sometimes utilize a resolution that is outside of the range permitted by your display. Similarly, your monitor may support resolutions that your graphics card does not, particularly if you’re switching from a 60Hz to a 240Hz display.

Experiment using a different monitor or computer

If you’re certain that there isn’t a software problem (such as outdated drivers) producing no signal to your display, you may need to test a different monitor or PC as part of your troubleshooting attempts.

Replace your computer’s display with a spare (if you have one available). If the issue is duplicated, it is probable that you have a problem with your computer that has to be investigated further.

Upgrade Your Hardware

If you’ve exhausted all viable software remedies and any faults with your hardware can be recreated with other connected devices, you’ll need to consider replacing your hardware.

A malfunctioning graphics card, for example, might prevent any visual output to your monitor, resulting in a no-input signal. If the drivers aren’t the issue, you’ll need to get a new graphics card.

Similarly, a malfunctioning display that isn’t compatible with various devices isn’t going to mend itself. You should investigate your warranty repair alternatives or, failing that, consider purchasing a new monitor.

This would also be a wise move if your monitor flickers or if there are signs that the equipment is failing. This might be the situation if your display takes a lengthy time to turn on, for example.
