First, disconnect and reconnect the HDMI or Display cable. Then make sure your GPU is properly connected. If the problem is still there, it could be an overheating issue. So, install monitoring software and check the temperature. Otherwise, your GPU might have a hardware problem.

However, these are nothing but just a short preview. To help you understand clearly, we’ve discussed this in detail.

Monitor Disconnects When Playing Games – 5 Reasons

These are very short procedures, and they don’t take very long to complete. So, let’s buckle up and get going –

A Loose Connection:

A monitor is an output of what your GPU is computing. So, a faulty/loose connection can be the culprit behind your disconnection. Also, out of all causes, this is the most common one.

HDMI Not Properly Connected

Solution: Disconnect and Reconnect Your HDMI or Display Cable

First, find the display cable of your monitor and gently disconnect it. Now clean the cable and the display port properly. Carefully reconnect the cable to the proper port, and the first step is done!

Now, we’re going to check the GPU port. The procedure is the same as before. Gently take out the HDMI or display port and clean it nicely. When that’s done, check around the GPU port. If there’s dust, clean them. When you’re done, plug the cable back in.

Now, start your computer and check whether the issue is fixed or not. In most cases, this will solve your problem. Also, your display cable might be faulty. Although this is an extremely rare occasion, no stones should be left unturned.

GPU Not Properly Connected

Solution: Check the GPU Connection

First, clean around the GPU and gently disconnect it from the PCI-E slot. For cleaning, you can use a small blower. It’s super-efficient and better than a cloth.

If you don’t know how to disconnect a GPU, follow these procedures below –

  1. Locate the latch/clip of the PCI-E Slot.
  2. Unlock the latch but don’t pull out the GPU yet.
  3. Unscrew the GPU properly.
  4. Gently pull out the GPU.

Now, inspect the PCI-E slot properly. Is there dust inside? If the answer is yes, get some tissue and clean the PCI-E slot properly. Also, don’t forget to clean the PCI-E slot connector of your GPU.

Now, clean the other parts of the GPU. Try to get rid of as much dust as you can. Make sure you’re cleaning the heatsinks as well. When completed, match the connector with the PCI-E slot and gently attach it. You will hear a tiny click when you’re done.

Don’t forget to close the latch and screw the GPU properly. Now, start the computer once again and test the reconnection.

Overheating Can Temporarily Shut Down Your GPU:

Like every electronic device, your GPU can overheat when under heavy load. This mostly happens when you run programs that aren’t compatible with your GPU.

Also, there’s a possibility that your GPU is overheating because of faulty hardware. So, we’ll get back to this later.

Solution: Install a GPU Monitoring Software

Some of these software’s are GPU-Z, CAM, CPU-Z, etc. These are very easy to install and use. Just run them, and these will show you the GPU temperature. Normally, your GPU will never cross 80 degrees Celsius under pressure.

Nevertheless, you can easily find the ideal temperature of your particular GPU from the manufacturer’s websites. But, of course, they vary from model to model, so don’t panic just yet.

Now match the results, and you’ll have an idea about what’s going on with your GPU.

Running Incompatible Games And Programs

Many video games have their GPU requirements. Running those games on a weaker GPU can cause overheating as well.
