Visual artifacts, anomalies, lagging effect, after-image, and distortions in a picture—these are some of the terms associated with monitor ghosting. Unfortunately, ghosting on a monitor is a common problem and can seriously affect your experience by damaging the image quality, mainly during fast-moving scenes. Hence, here we have covered all queries regarding that like, what is ghosting on a monitor, how to fix ghosting on the monitor, how you can run ghosting test monitor ghosting example, and much more
What Is Monitor Ghosting?
Monitor ghosting is a type of image artifact. It arises when the trial of pixels traces behind the moving objects. It’s like the motion blur effect. However, permanent changes may not be caused to the display for instance, image retention or burn-in effect. Instead, one will only notice ghosting during fast-paced scenes that involve moving objects as a blurry trail without any permanent impact on the image. 
What Causes Monitor Ghosting?
Ghosting monitor happens because there is a slow response time or slow refreshing rate on certain types of LCD panels used in monitors. Refresh rate is the number of times your monitor can display new images within a second. It is expressed in Hertz. Ghosting on a monitor happens because the physical pixels cannot update fast enough when the image is refreshed and don’t keep up with the image. For example, as VA panels have the slowest response time, hence ghosting on a monitor is most visible on them. Now, the most expensive VA monitors (particularly gaming ones) don’t show ghosting artifacts. However, cheaper IPS monitors might show ghosting artifacts but to a considerably lesser extent.
In other words, ghosting is inherent with some LCD panels and cannot be removed entirely.
Many factors can cause monitor ghosting, Poor quality cable, disconnected or damaged, outdated video card drivers, monitor settings, or other devices that interfere with the monitor if they are placed close enough to it. Sometimes, even printers can impact monitor ghosting. Ghosting or similar effects such as Coronas or Inverse ghosting can be caused by specific display settings. For higher refresh rates one overclocks their monitor, that can also cause image artifacts that are like monitor ghosting.
How Do You Test for Monitor Ghosting?
A way to know if your monitor has ghosting is the UFO Motion Test. You don’t need to move the mouse during this test because it might cause your browser to crash. However, with your naked eye, you will notice that the UFO is color distorted, has blurry trails, lacking definition, and leaving a trail on the screen.
Fortunately, this monitor ghosting test will tell you if your monitor is in good shape or not. If there are no problems, it will show a green sign that says “READY.”
If you see ghosting on your monitor, something might be wrong. If you do, an orange message will show up on the screen telling you what to do. And the tool will give suggestions for how to fix it.
Ghosting is a problem with screens. The test can tell you about ghosting and other issues related to screens, like how many frames per second they show or what the monitor refresh rate is.
How To Fix Monitor Ghosting?
If you are experiencing ghosting on the monitor and it is interrupting your viewing or gaming, then how can you fix the ghosting on the monitor? There are a few different ways that you can improve monitor ghosting.
Adjust Your Monitor Settings
Most include changing or slightly adjusting specific settings within the monitor itself; some features make the screen look better. They include Dynamic Contrast, Motion Blur Reduction, and Noise Reduction. Unfortunately, these features can lead to ghosting. Try turning on and off some features to see if this fixes the Ghosting on Monitor.
Activate Your Monitor Anti-Ghosting Function
The most popular way to fix the ghosting is by turning on the overdrive function. Depending on the monitor manufacturer, this setting has different names which are given below;
- Overdrive for Acer monitors
- Response Time for LG and Samsung monitors
- Trace Free for ASUS monitors
- AMA for BenQ monitors
For manufacturers other than the above, it’s usually display as Overdrive or Response Time in settings.
Through the UFO motion test, you will tweak the overdrive setting to make your image clearer. Until the ghosting is minimalized, keep on changing the levels of overdrive. To find the sweet spot, you will need to put the setting at medium or one level below. Then the corona artifact or inverse ghosting affects start to emerge.
Inspect your monitor cable to see if it is in good working order and securely connected. A loose connection can cause display issues, including ghosting.
Update Your Video Card Driver
Keeping your NVIDIA or AMD graphics card drivers up to date is essential. You might have problems with images if you do not update the drivers of the software on your computer. To fix this, make sure you update your computer’s driver.
Monitor ghosting is when there are blank spaces on a screen. It happens with fast games. In movies and TV, people notice it less. But it does not cause as much of a problem as it does for people who play video games. Monitor ghosting isn’t going to permanently destroy your monitor, even if it may destroy your gaming experience or your movie. The best thing you can do is research your monitor before buying it to see if ghosting is an issue for everyone or if it doesn’t have ghosting problems.
