What To Do When Monitor Loses Signal While Gaming

STEP 1: Check Your Power and Cables

Before you go to Amazon to purchase a new monitor, make sure you take a thorough examination of your PC and monitor to make sure that the cables are in good working order and that both devices are receiving sufficient power.

It is possible to carry out this test by following all cables connected to your monitor and computer. Make sure there aren’t any loose connections between the two devices.

A broken HDMI cord could prevent your computer from connecting to your monitor at the correct output, losing signal when you play.

Another cable is aware of is the display cable. Make sure it’s not damaged or defective. If the cable you have is worn out, purchase an upgrade or locate another. This will instantly fix the screen display and allow you to enjoy your gaming.

The power issue can also hinder your monitor from turning on or functioning correctly.

If your monitor is turned on, but you’re seeing an error message that says “No Signal,” it could be that your computer is malfunctioning or isn’t functioning correctly.

If your computer is running well, but your monitor doesn’t show something, then your monitor is the problem. Always connect your PC and monitor into a surge protector to shield the devices from power surges that aren’t consistent.

STEP 2: Check Your Input Source

If you’re not receiving any signal during games, the source of your input may be affected.

The monitor could not recognize or transfer only a portion of the graphics output from your computer. This is a common issue when your monitor’s input source is set to a different device.

Gaming monitors come with various input sources, such as HDMI, DVI, and VGA inputs. These inputs let you attach your display to several devices.

The devices you connect to could include the PC you own, PS5, Xbox, or perhaps multiple computers. Then you’ll need physical controls or the firmware of your monitor to transfer between the devices.

If this is true, make sure you have set the correct input source for your monitor.

If this isn’t the case, you can try using other inputs, such as DVI and HDMI, to transmit signals from the computer directly to your display.

STEP 3: Make Sure Your Monitor Isn’t Overheating

If your computer suddenly loses the video signal, it could be because of the temperature being too high. Monitors are designed to shut down if the temperature gets excessively high.

This method lets them keep the electronics inside their circuits. There are numerous reasons that a computer monitor could overheat, such as dust buildup, blocked vents, and high humidity or heat.

To resolve this issue, unplug your monitor and let it cool completely. Then, try to clean the buildup of dust out of the casing of your monitor using canned air.

Also, take a look at the temperature of your computer’s room. If you find it too hot, you can cool it off with an air conditioner or an air conditioner. Be sure to let the room be extremely cool before switching off your monitor.

Older CRT monitors can get hot very quickly. If you’re using one of them, replacing your monitor to fix the heat problems is possible.

STEP 4: Make Sure Your GPU Isn’t Overheating (Graphics Processing Unit)

If your computer isn’t sending signals to your display, It could be the consequence due to it being the result of your GPU overheating.

The average temperature for the GPU in games is between 65° Celsius between 85 and 65 degrees Celsius. It is possible to use tools for diagnosis such as Speccy to determine the GPU temperature.

If you notice the GPU you’re using is heating up, It is recommended to cool it down before continuing playing. Once it’s cool enough, plug the monitor into your computer and determine if the problem is fixed.

GPUs are prone to overheating if they don’t receive enough air or block their cooling system.

The temperature in your room could contribute to why your GPU has been overheating. Make sure that you clean your GPU, remove dust particles, and control the temperature in your gaming area.

Also, you should clear the vents to ensure adequate airflow and to modify your cooling device.

Check that your PC is turned off and unplugged before performing any maintenance work on it. Be sure not to employ a damp, spongy towel to scrub your computer and its parts because doing so could result in permanent damage to the components and perhaps even to the motherboard.

Check Your Monitor Resolution

The majority of monitors are made to display a specific set of resolutions. When your graphic card sends a resolution higher than your monitor’s specified range, the monitor will likely stop working or display a blank screen or display a blank signal message.

It’s good to know that the solution to this problem is simple. All you have to do is alter the display settings.

If you alter the resolution on your own and you notice that the resolution of your monitor has decreased, wait around 15 seconds, and Windows will then automatically restore to the original resolution.

Suppose you did not alter the display settings on your own. In that case, Windows might have automatically altered your monitor’s resolution to a higher resolution. This could be the reason your monitor is losing signal or stop working. To resolve this issue, just restart your device in safe mode.

Your computer will be using a low resolution in safe mode. In this mode, you’ll be able to set the default display settings to a resolution suitable for the monitor you’re using.

Check your monitor’s manufacturer’s website or manual to determine which resolution for your monitor. If you can’t find it, you’ll have to test it out to find the optimal resolution for your screen.

This can be done by testing different resolutions. Windows will always return to the resolution you had previously used before plugging in the monitor if the monitor doesn’t support the resolution.

Make Sure Your Monitor Isn’t Defective.

A monitor that loses signal when gaming could be due to defective circuitry inside the monitor. If there’s a malfunction in the circuitry or wiring short, the monitor may periodically lose signal or simply disappear altogether. If this happens, the best solution is to replace the malfunctioning monitor.

Restoring a monitor is a lengthy process and can cost lots of dollars. Repairing your monitor could be enough to pay for purchasing a new computer or an entirely new monitor.

To ensure your monitor is responsible, Try testing the monitor with a different computer as you test your PC using a different monitor.

If you are experiencing the same issue on your monitor, it could be time to replace the monitor. However, if your monitor is functioning and the second monitor is not working or shutting off in random intervals, it could be that your computer is the cause.

Make sure that the drivers on both the PC that you are using and the monitor are in good condition to determine the issue.
