Here’s Why Your Monitor Loses Signal While Gaming (& How to Fix It)

Does your monitor lose signal while you are gaming?

If so, I can understand your frustration. This has happened to me dozens of times throughout my years as a gamer even though I’ve always had reasonably good gaming monitors.

A simple time out of a few seconds can make a huge difference to how your game rolls out, especially if you are playing a tournament where every second counts, which can be extremely annoying.

After some extensive research on the matter, and a chunk of personal experience, continue reading as below, I will walk you through various different reasons why you may be losing signal while gaming.

I will also help you troubleshoot the various different possibilities for losing signal, find the source to the problem, and provide you with a few solutions to help you solve the cause of losing signal in just a few minutes.

Before we jump into the detail, here’s a quick summary of why your monitor turns off when gaming:

  • Problems with your drivers
  • Issues with your graphics card
  • Malfunctioning cables

Problems With Your Drivers

If your monitor randomly loses signal when gaming, sometimes, that could be due to your drivers. They may be outdated, corrupt, or just malfunctioning for no apparent reason.

The Solution

Check for updates on your graphics drivers and run them, then see if this fixes the issue.

If it doesn’t, uninstall all of your graphics drivers and install them again. Use your GPU’s software to make those necessary updates and reinstalls.

If your GPU is from Nvidia, then in that case, install the GeForce Experience software. From there, you can install, uninstall, and amend your graphics. If you are using a GPU by AMD, download the AMD Radeon software.

Issues With Your Graphics Card

If your monitor loses signal when gaming, your graphics card could also be the one to blame. There could be quite a lot of things wrong with it, and so, discovering and isolating the reason may save you a couple of hundred dollars before you chuck it in the bin, while it is perfectly fine.

The Solution

In case you anticipate that your GPU is at fault. One of the most common reasons is high GPU temperature.

Increased Temperature

Does your GPU overheat? The standard GPU temperature is between 65C to 85C while gaming. If it’s any higher, there is something wrong. You can check your GPU’s temperature by using a tool like Speccy.

If you find that your GPU is overheating, that within itself is a pretty decent reason why you may lose signal, especially if you have an older GPU. Overheating can be caused for a number of different reasons including increased temperature in your room to covering your PC fans with random objects that can block the flow of air within the system.

The most common reason for overheating, however, is if you haven’t cleaned up your PC in some time. The chances are that dust particles have ended up in your PC and are obstructing the GPU’s cooling system from effectively operating at its true potential.

So, clean up your PC and GPU’s cooling system very carefully, ensure that your PC can get decent airflow, and check if the problem persists.

Note: Before you clean any part of your PC, ensure that it is completely turned off and unplugged from the socket. You should also never use any sort of damp cloth to clean any part of your PC as that can cause damage to the parts.

Malfunctioning Cables

Whether you are playing in 60 Hz or 244 Hz, once in a while, your monitor may just lose signal randomly. On pretty rare occasions, your HDMI cable may be at fault. Either it’s not plugged in or it is that old that it is simply beginning to malfunction. Another reason may be that if you are trying to get 120Hz on your gaming TV from your PC or other such combinations that your cables may not be supporting.

The Solution

Before you buy a new cable, take out the cable out of the port, clean it up a little bit, and then make sure to plug it back in properly. You can also try out if the cable works fine on a different device other than your PC/monitor to be sure that it is in fact the cable that is the problem and not any of the reasons listed above this point.

If you still lose signal after doing that, then you know it is time to change your cable with a new one.

Final Thoughts

Above are some of the most common reasons why you may be losing signal while gaming. Hopefully, after reading what I had to say, you have found out the reason behind why you are losing signal while gaming and can now play without any interruptions. If you are having any troubles still, please let me know in the comments below and I would be more than happy to help.

  1. When I’m playing games my monitor still goes to no signal. My drivers are up to date, the temperature of my gpu is 65 C and u just changed the HDMI cable but it still keeps going to no signal. Idk what it is. The whole pc is brand new (8 months)!so the parts are new. Idk if I should buy a new video card or not but it’s really expensive. I have a Radeon 580X right now.

    • Mine has been doing the same thing! I’ve had this PC for a year and my monitors lose connection only when I play certain games– like Phasmophobia or Valorant (with high graphics settings. I can play Valorant with low graphics settings). I’ve tried all the fixes I’ve seen on the internet-updating drivers, reinstalling drivers, cleaning pc, etc. Still no fix.

    • im having the same issue dude with mine my pc has been doing this since day 1 recieving my pc its cost me over £2000 just for the pc and im having issues ive sent the pc back twice and they cant find the fault which i dont understand so once again im having to send this back again untill this problem is solved.

  2. I face the problem just 2 weeks after buying a new monitor… samsung G5 32 inch.. and my acer 32 serves as 2nd monitor.

    Playing games especially online always cause this trouble.
    Temperature seems normal and during the no signal its only around 70 degrees C.

    I have bring the CPU to office, Changed the PSU, same problem happens even though with office monitors..

    I have updates windows, uninstalling nvidia graphic drivers, and installed it back again…

    My pc is i9-9900k, rtx2060, 32gb ram ddr4.

    Not overheating issue
    Not monitor/cable issue (even today testing with brand new cable also same)
    Not windows/ driver issue…

    The problem is still there.

  3. My pc ran excellently till I installed office 2019 on it. Now I cannot play any games without my screen being cut off.
    There are no hardware issues at all…

  4. Both my monitor and other screen lose signal, my keyboard and mouse stop working but my PC is still running. I’ve tried almost everything to fix the problem and now resorted to using my secondary backup PC for gaming. Please, if you have any idea what could be causing the problem I’d appreciate it, thanks

    • I have this very same issue. My monitor keeps losing signal in the middle of gaming and I have to reboot. Sometimes my mouse, keyboard, monitor and speakers wont boot when I try to hard restart after a monitor failure. Iv’e done everything from uninstalling drivers and reinstalling them. To cleaning them to upgrading the PSU. Motherboard and CPU are brand new top of the line alder lake and Z690. Not sure what to do at this point.
