Monitor Going to Sleep? [9 Ways to Fix]

You can’t get a nice sleep when your monitor goes to sleep continuously and automatically.

Today, you are going to find the causes and fixes for a monitor that is sleeping continuously. For every problem with the computer, there should be a lot of reasons.

So for this issue, we need to analyze the PC in different aspects.

Make sure the GPU is sending signals to monitor

The first thing you need to check is whether the GPU is sending the right signals or not. Because the monitor is the output device in the computer, it only displays the results coming from the CPU. 

Here you can find multiple ways to fix signal errors on your monitor.

Make sure you make the connection between the monitor and the GPU and avoid loose connections.

You need to select the compatible cables for the connection because when you use converters like HDMI to VGA, HDMI to Display port, etc., the signals from the GPU will convert.

In such a case, the wrong converter will make the wrong conversion and result in no signal on the monitor, which means the monitor gets to sleep.

Replace the faulty GPU

Have a problem with the GPU? You need to replace it.

Don’t worry, I know the value of your penny. First, apply the fixes listed here, then you can decide whether or not to replace the GPU.

First, you need to check whether the problem is from the monitor side or the GPU side. To do that, connect your CPU to the other monitor or TV. Here you can find the differences between TV and monitor. But when it comes to functioning, they are pretty much the same.

If the connected monitor or TV is working fine, then the problem is with the first monitor. Otherwise, you need to find out the issues with your GPU.

The graphics card can malfunction when it is overheating or when it doesn’t get enough power.

You need to reapply the thermal paste on your GPU when it is overheating. Click here to find out when you should reapply the thermal paste on your PC.

Don’t have overheating problems? That’s cool.

If you have problems like PC freezing, sudden app shutdowns, etc, these are the symptoms of a low power supply in the computer. Make sure you have at least 450 Watts PSU. For a gaming PC, at least 600 Watts.

Not a problem with temperature and the PSU output is also sufficient? Then you need to change your graphics card. Browse the latest GPUs in the store and find the compatible ones for your motherboard.

Move the cursor to make the screen active

The latest monitors come with a power-saving mode.

The power-saving mode in a monitor will help save or consume less power by turning off the display when the person or user is not using it. Just you need to move the cursor or press any button on the keyboard to make the screen active.

Some monitors have controls to disable it, but some don’t. However, the power-saving mode is a pleasant feature in monitors.

We have two cases to use this method to wake up the screen.

1. Bring back the monitor from power-saving mode

If your monitor has this feature (power saving mode), then the monitor will automatically get into PSM if it doesn’t get any signals from the GPU. In such a case, move the cursor or eject the connected cable (HDMI, VGA, or other) and reinsert either way you can wake up the screen.

By the way, the power-saving mode is not a problem, it is a feature. Accept it.

You can check the monitor settings to disable it if you want. No guarantee all monitors have access to PSM.

2. To Wake up the PC from Sleep mode

Sleep mode – One of the best features of Windows PC.

The above link will guide you on everything about it like how to set it up and when to use it.

Make sure you make the screen timeout after 5 minutes at least and sleep mode hold time for at least 10 minutes. Because if you set the time for 1 to 3 minutes, it makes you feel the monitor go to sleep very soon and frequently.

Avoid loose cable connections

Loose cable connections will cause the monitor to malfunction.

Unplug all the cables, and clean the dust on them and the monitor and the CPU ports. Then properly connect the cables. Everything will be set.

Replace the damaged cables

Observe the cables properly for damage. You may find burnouts, damage cracks, pin damage, etc. If nothing happened like that, that’s cool and happy. But you can’t find it until you check, so check the cables for physical damage.

What to do when you have cable problems? Need to replace them. Make sure you choose a high-speed data transfer cable with a length of at least 2 meters.

Remove the heavy load on your monitor

The overload on your PC can cause its malfunction. For example, your monitor supports HD resolution but you are trying to play the ultra HD or 4k video song. In that case, the monitor can’t bear too much load and has a high chance to stop working.

This is not a big issue unless you are repeating it again and again.

Remove the unwanted load on your monitor and use it by considering its standard. You can upgrade your monitor for more features.

Update your PC drivers

Sometimes the bad display drivers can cause your monitor to sleep. The drivers are the mediators between hardware and software.

It is highly recommended to keep your PC drivers up-to-date. The outdated drivers can lag system performance. You don’t want a slow and trouble-making PC. Right? Here are the best ways to speed up your PC.

Also, you need to know about the drivers on the computer and how to update them step-by-step. That’s here.

Replace the faulty monitor

And finally, the monitor itself is the suspect.

If the monitor has a problem, then it has a high chance of not working. But in some rare cases, it will show malfunctions like not turning on, sudden fall in asleep, lines on the screen, freezing, etc.

If the problem occurs with the HDMI port, you can use the DVI port. But, when the motherboard of the monitor is damaged, you do nothing.

In such a case, you just need to replace your faulty monitor with the new one. If you have a spare monitor, use it. No problem with that. Otherwise, you need to buy a monitor to use your PC.
