Monitor Ghosting – What is it?

Monitor ghosting can be a pretty irritating problem on your PC. This is a small trail of pixels that follows movement and proves to be a distracting presence. Even minor monitor ghosting can be a really big annoyance on your screen, You can put up with it, but this is the kind of problem that is going to drive you mad if it isn’t dealt with, and it can be fixed pretty easily. 

Monitor ghosting can also often resemble dead pixels. This can cause people to think the problem is unfixable and it is just something they’ll have to live with. This isn’t actually the case. Monitor ghosting is an entirely different thing, and it is a problem with how your monitor is running rather than a hardware defect. If you have monitor ghosting, it is pretty simple to address.

What is Monitor Ghosting?

Monitor Ghosting is a type of artefact that can appear on your PC screen. It is typically a trail or line of pixels, they form and follow behind moving things on your screen. They can appear like a ghost, tracking slightly behind what’s on your screen and distorting things. 

If you’re watching video on your PC or playing games, monitor ghosting can really turn into a hassle. Monitor Ghosting is a simple problem though. Unlike similar issues with artefacts, this is one that can be fixed without having to replace your monitor or take other drastic measures with your hardware.

Is Monitor Ghosting Permanent?

Monitor ghosting might resemble more permanent problems with your display, but it is actually temporary and can be easily fixed. Monitor ghosting is caused by your monitor having a slow response time and not catching up to the image refresh rate. This makes it a temporary problem since the artefacts and ghosting are only going to last as long as you are producing the movement on the screen that your LED can’t keep up with.

Why Does Monitor Ghosting Happen?

There are a few different reasons why monitor ghosting can occur. These are the main ones:

  • Monitor ghosting is caused by an LCD panel being unable to update the physical pixels on the screen as fast as the image is being rendered. This results in the effect you see on your screen.
  • It can be caused by a slow response time on your LCD. 
  • Sometimes ghosting isn’t a problem with the monitor itself. Sometimes the issue is with your monitor cable.
  • Your monitor settings might be causing problems too.
  • Overclocking a monitor to achieve a higher refresh rate can also cause ghosting.
  • Although monitor ghosting tends to happen on cheap PC monitors, it can affect any monitor of any value.

How to Fix Monitor Ghosting

How you fix monitor ghosting is going to depend on why you’re experiencing the problem. These are the solutions to the common sources of monitor ghosting. If you’re unsure why your monitor is having this problem, try out the more common ones and work out where the problem is by process of elimination:

Overdrive Function 

Most monitors have an overdrive function that can solve this problem. They do have different names from different manufacturers though. 

  • Acer monitors call it overdrive.
  • BenQ monitors call it AMA
  • ASUS Monitors call is Trace Free
  • LG and Samsung Monitors call it Response Time.
  • Other brands will likely call it overdrive or response time.

Turn this function on. This allows your monitor to compensate for what it can’t display and remove this effect. You should alter it until the effect is dealt with and you’re free from your monitor ghost.

Monitor Visual Effects

While Overdrive functions are usually the solution to monitor ghosting, there are some others you can try out if that doesn’t work. 

These are some settings that use visual effects on your screen, these can be the cause of your ghosting:

  • Perfect Clear
  • Dynamic Contrast
  • Motion Smoothing
  • Noise Reduction

Turn these off and see if it affects your monitor ghosting.

Your Frames Per Second Rate

Another possible problem with your settings only applies to monitor ghosting in games. If you’re attempting to run a game at a higher frame per second than your monitor can cope with, you’ll need to adjust this. Your frames per second can’t be more than your monitor’s refresh rate, so adjust your cap to match this. Artefacts of all kinds can be caused by this, so address this if you’ve got a problem with monitor ghosting while gaming.

Your Cable

This is a pretty annoying cause of monitor ghosting. Try a different monitor cable and see if this solves the problem. If it does, you’ll have to replace your cable.

Your Monitor Itself

If none of this addresses your problem, the cause is your monitor’s response time. It isn’t much you can do here other than replace your monitor with one that has a better response rate. If you’re not satisfied with your monitor’s current refresh rate, then this is the only real solution to get an upgrade.

Conclusion

Hopefully this has given you some insight into what monitor ghosting is and the steps you can take to try and resolve it.
