What is monitor ghosting, and how do i fix it.
Do you get trails on your monitor while playing games?
What is monitor ghosting, what causes monitor ghosting, run a ghosting test to identify the issue, how to fix monitor ghosting, beware pixel overshoot when using overdrive, don't confuse ghosting with blooming, key takeaways.
Monitor ghosting is a name given to pixel trails that appear during fast-paced motion as a result of slow pixel response times. You can fix ghosting using the overdrive setting in your monitor's menu, but beware of inadvertently causing pixel overshoot instead.
Do you see trails or blurring on your monitor during fast-paced motion or games? Ghosting can affect LCD monitors and televisions, but you may be able to rectify it with a simple setting. Here's how.
Monitor ghosting refers to visual artifacts that follow moving objects, particularly prevalent when gaming or displaying other fast-moving content. You might not notice ghosting in normal desktop use or slower-paced games, but it can be distracting when you're playing first-person shooters, racing games, or even scrolling quickly on a web page.
Some displays may be more prone to ghosting under certain conditions, for example in especially dark scenes. This can cause a loss in shadow detail and turn large parts of the screen into a smeary mess. On top of being frustrating to deal with, ghosting may contribute to eye strain over long play sessions.
Ghosting can affect any type of LCD panel, including monitors and televisions. It's more common on VA-type panels , which are the main LCD panel types used on televisions. Ghosting shouldn't be an issue on OLED panels but self-emissive displays may instead suffer from a form of temporary (and potentially permanent) image retention on static elements like health bars or news tickers.
Monitor ghosting is caused by slow pixel response times , where pixels aren't able to cleanly change from one color to another in good time. The problem is more noticeable at high frame rates, where frame times (the time in which a new frame is delivered) may be faster than the monitor's response time.
Monitor manufacturers often advertise, alongside other monitor specifications like contrast ratio and refresh rate , a monitor's response time in milliseconds. You may find these figures listed as "GtG" (gray-to-gray) and "MPRT" (Moving Picture Response Time), and both refer to different metrics.
GtG describes how long it takes a pixel to change between two colors. MPRT describes how long a pixel persists on the display. In both instances, a lower number is desirable. It's possible to have a fast GtG value and a slow MPRT value, which may cause ghosting to appear on your monitor.
Blur Busters has an excellent explanation of how GtG and MPRT interact, what other factors affect these values, and how manufacturers attempt to solve the issues of image persistence.
Since these values are used interchangeably and often without context by monitor manufacturers, it's advisable not to rely on a single advertised response value alone when making a purchase. We'd recommend reading reviews of any monitors you're thinking of purchasing on websites like RTINGs to see if ghosting is present and (if so) how bad it is. You can also consult our roundups of the best monitors , best gaming monitors , and best ultrawide monitors .
If you're already seeing ghosting or pixel trails when playing fast-paced games, you're already aware you have an issue. You may also want to run a ghosting test on your monitor. This is handy if you're in the process of testing a monitor out in a showroom or thinking of buying something second-hand that you can get your hands on before you buy.
Use the Blur Busters UFO Ghosting Test to perform a ghosting test. Use the "Speed" drop-down menu to adjust the pixels-per-second, to simulate slower or faster on-screen motion. If you see pixel trails that are consistent with ghosting, you have identified the issue.
This test may also show up other artifacts which can appear when you try to fix monitor ghosting, so you'll want to consult the test to see if the remedy below strikes a balance that you're happy with.
You can attempt to rectify monitor ghosting by using your monitor's overdrive setting . By using higher voltages on individual pixels, response times can be improved and ghosting may be reduced or disappear completely. Different manufacturers have different names for overdrive settings, so you may need to dig through your monitor's built-in preferences to find it.
Look for labels like Overdrive, OD, Response Time (LG and Samsung), TraceFree (ASUS), Rampage Response (ViewSonic), AMA (BenQ), or similar. Some monitors won't have this setting, in which case you won't be able to increase response time. Experiment with turning your response rate up (if you find the setting) while running the Blur Busters UFO Ghosting Test to see if you notice ghosting becoming more pronounced.
You should also be wary of other settings including noise reduction and dynamic contrast, or, if you're using a TV, motion smoothing . These can all contribute to unwanted artifacts and ghosting.
Unfortunately, monitor overdrive isn't a perfect fix. The setting usually comes in a range of "strengths" or speeds, like a scale of one to five, or names like "fastest" or "extreme". It may be tempting to turn this setting all the way up, but the main drawback to doing so is the introduction of pixel overshoot or coronas.
These unwanted artifacts occur as a result of the pixel going past (or "overshooting") the desired color. Also known as inverse ghosting, the effect is caused by pixels transitioning too quickly and can result in a similarly distracting effect. Which setting you choose in terms of remedying ghosting with overdrive and avoiding pixel overshoot will depend largely on which monitor you're using.
It also depends on your tastes. A small amount of ghosting may be more tolerable than the coronas caused by pixel overshoot. More often than not you're going to want to settle on a "medium" overdrive setting to get the balance right.
Blooming is another undesirable visual phenomenon that you may have heard of. Whereas ghosting refers to problems at the pixel level caused by response times, blooming is caused by LED backlighting, especially on displays that use full-array local dimming .
If you want excellent response times and no blooming, consider investing in an OLED display (or a newer QD-OLED monitor ).

How to Fix Ghosting on Monitor [Easy Steps]
Monitor Ghosting is a common issue that you might see on any monitor. If you’re playing a shooter or an action game, you’re likely to encounter this issue which can ruin the whole gaming experience. It could also occur when you’re editing videos or working on tasks that involve displaying fast-paced scenes .
The good news is, it’s easy to identify if your monitor has this issue. Plus there are some known effective fixes. In this article, we’ll explain what monitor ghosting is, why it happens and most importantly, we’ll cover how to fix it. Read on for more information…
What is monitor ghosting?
Monitor ghosting or screen ghosting, as the name indicates, is a monitor/display issue. It has little to do with your system. Monitor ghosting usually occurs when there are multiple images moving fast on your screen, or when you’re moving your mouse quickly. If your monitor is ghosting on your game, you’ll likely notice:
- Blurry trails following moving objects
- Previous image frame remains on your screen for a few seconds when you’ve moved to the next image frame
- Current image is blurry
- Discolored images
You may now wonder, why is your monitor ghosting? Ghosting is most frequently seen in LCD monitors, but for any type of monitor, the two main factors remain the same: refresh rate and response time.
Simply put, screen refresh rate refers to how often your screen displays a new image. For example, a 60Hz refresh rate means that the monitor refreshes itself 60 times per second.
Response time , on the other hand, is the time it takes for a pixel to shift between colors. The more responsive your monitor is, the shorter the response time it’ll have.
If your monitor has a low refresh rate and a high response time, you’ll likely experience the screen ghosting issue.
How do I fix the ghosting on my monitor?
To test if your monitor has the ghosting issue, you can find several tests online. The most popular tool is UFO Test . You’ll get a green signal saying READY if your monitor doesn’t have a ghosting issue. Otherwise, you may get an orange signal suggesting a specific problem with your monitor.
If you’ve identified the issue, check out the fixes below. You don’t have to try them all, just work your way down until you find the one that does the trick!
1: Check your monitor cable
2: Check other devices connected to your PC
3: Adjust your monitor’s display settings
4: Update your graphics driver
5: Check your video port
Fix 1: Check your monitor cable
First, you want to make sure that your monitor cable is firmly plugged in . Try unplugging then replugging in the cable and test if the issue persists.
You may also want to check if your monitor cable is intact . A damaged monitor cable could result in monitor ghosting, in which case you should change your monitor cable and test if the problem persists.
If your monitor cable is functional, move on to the next solution.
Fix 2: Check other devices connected to your PC
Sometimes other devices connected to your PC, such as your keyboard or speaker could interfere with your monitor’s function. It could be an issue of proximity, meaning that you just need to keep your monitor far from those devices .
Or, you could disconnect those devices one at a time and test if your screen still ghosts . Make sure to check the wireless devices as well. If one of your devices seems to cause the ghosting issue, try not to use it with your monitor at the same time.
If this fix doesn’t help, try the next solution.
Fix 3: Adjust your monitor’s display settings
As we mentioned above, refresh rate and response time are the main factors that are responsible for the ghosting issue. You can adjust your monitor’s settings to achieve a higher refresh rate and a lower response time which helps prevent your screen from ghosting.
1: Adjust the response time
2: Adjust the refresh rate
3: Additional tweaks (Optional)
Adjust the response time
Monitor manufacturers have made this easy – you’re able to adjust the response time via the OSD (On Screen Display) menu:
- Press the menu button on the front or the side of your monitor.
- Navigate to the settings for the response time, and adjust for a lower response time . Different brands use different terminology: Asus & HP : adjust the OverDrive function to medium or low, or completely turn it off. Asus : enable the TraceFree function. BenQ : enable Advanced Motion Acceleration (AMA) . DELL : adjust the Response Time setting. Turn it to fast or super-fast. LG & Samsung : adjust Response Time . Other brands : You could look for Response Time, OverDrive, Response Time Compensation, Motion Acceleration, Response Time Acceleration , etc.
Adjust the refresh rate
If your monitor supports variable refresh rates, you can set it to a higher value to tackle the monitor ghosting problem. To view the refresh rate of your monitor and make adjustments if possible:
On Windows 10:
On Windows 7/8:
Additional tweaks (Optional)
In addition to response time and refresh rate, you could experiment with other display settings to see if it helps solve the monitor ghosting issue. Make sure to test your monitor’s functionality while adjusting. To make additional tweaks, look for these settings:
Fix 4: Update your graphics driver
Although we explained earlier that screen ghosting is primarily an issue of the monitor, not of GPU, you could still try updating your graphics driver. When you can’t identify what’s causing your monitor to ghost, it’s a good idea to do so since it generally fixes and prevents many display issues, which may include monitor ghosting in your case.
One way to keep your video card driver up-to-date is to manually update it via Device Manager . If Windows suggests your driver is up-to-date, you can still check if there’s a newer version and update it in Device Manager. Go to the manufacturer’s website, and search for the latest correct driver. Be sure to only choose a driver that is compatible with your Windows version.
Automatic driver update – If you don’t have the time, patience, or computer skills to update your driver manually, you can, instead, do it automatically with Driver Easy . Driver Easy will automatically recognize your system and find the correct driver for your exact video card and your Windows version, then it will download and install them correctly:
- Download and install Driver Easy.
Restart your PC for the new driver to take effect. Check if the monitor ghosting issue has gone. If this doesn’t work in your case, try the last solution.
Fix 5: Check your video port
If the video port of your monitor is faulty, it could probably cause you screen to ghost. We recommend taking your monitor to a local repair store since it’s very difficult to identify the problematic component and replace it. If your monitor is still under warranty, you may also contact the manufacturer for support.

Monitor Ghosting: How To Fix It & How To Prevent It
Having a ghosting monitor can be more than annoying – it can impact your gaming performance, cause eye strain, and generally ruin your experience. Ghosting and image artifacts can be a real problem on even the best PC monitors.
These problems are most apparent when you are playing a game or watching a movie that has fast-moving scenes or images. It can cause the images to look like they are overlaid on each other.
In this guide, we will help you to understand what monitor ghosting is, what image artifacts are, and whether they are related, what causes monitor ghosting on even the best monitors and computers, and how you can avoid or remove ghosting from your screen.
What Is Monitor Ghosting & Why Does It Happen?
Check your other devices, issues that are similar to image ghosting, conclusion: monitor ghosting.
Monitor ghosting occurs when an image artifact shows up as a trail of pixels or as ghosts behind objects that are moving at a rapid rate. They also follow slower moving objects, but they aren’t as noticeable then. It is easy to see image ghosting when you are playing a first-person shooter game or when you are playing a faster sports game.
It should be noted that monitor ghosting doesn’t actually cause any damage to your display like some other image issues do (including image retention or burn-in). Instead, ghosting only really bothers people when there are those scenes that move too fast.
You will simply see the blurry trail without any permanent damage to the monitor or to the image itself. However, over time the image ghosting can get worse so that it seems like it created permanent damage.
Ghosting happens because there is a slow response time on certain types of LCD panels that are used in monitors. This happens because when the image is refreshed, the physical pixels cannot update fast enough and they don’t keep up with the image.
Sometimes, it will start by looking pixellated, and eventually, it will become smeared. In general, out of the most common types of LCD monitors, certain brands and types of panels are worse than others.
For example, VA panels have some of the slowest response times and are therefore more likely to show ghosting artifacts. That doesn’t mean that all VA panels have ghosting problems, but they are more likely to (and most do, in fact).
Some cheaper IPS monitors will also have ghosting and artifacts, but it is actually less likely. Ghosting is just part of having an LCD display and it is something that people should consider. It is an issue that cannot be completely stopped. Most manufacturers have been looking for ways to reduce ghosting artifacts, but they haven’t always had the most success.
This is because monitor ghosting isn’t necessarily caused by the monitor panel. It can be caused by many factors, including a faulty monitor cable or by other devices that are interfering with the monitor if they are placed close enough to it. Sometimes, even printers can impact monitor ghosting. Be sure to read reviews as it tends to happen on the same ones.
There are certain things that can cause ghosting more often than others. Overclocking, for example, your monitor for higher refresh rates can cause image artifacts that are similar to ghosting, or you may even get inverse ghosting.
How To Fix Monitor Ghosting
If you are experiencing monitor ghosting to the point where it is interrupting your viewing or gaming, then there are a few different ways that you can fix this problem. Most include changing or slightly adjusting certain settings within the monitor itself, even if the monitor is not what causes the problem.
The most common fix for monitor ghosting is to turn on the overdrive function. Now, the overdrive function is a bit confusing because almost every monitor manufacturers has a different name for overdrive.
Yours may be known as:
● AMA for BenQ monitors ● Overdrive for Acer monitors ● Response Time for LG and Samsung monitors ● Trace Free for ASUS monitors
If you have another monitor, you can look for “Overdrive” or “Response Time” and it will be there. If you can’t find either of those, you can look online to see what it will be called for your own monitor.
To correct this test, you will need to try a motion test of some sort. You can Google the term “Monitor Motion Test” and you will see a few different options pop up, but the most popular test is the TestUFO motion test. From there, you will be able to tweak the overdrive setting to make your image clearer.
You want to change the levels of overdrive until the ghosting is minimalized as much as possible. You want to do it as much as you can, but you will also need to avoid corona artifact. To find the sweet spot , you will need to put the setting at medium or one level below when inverse ghosting or the corona artifact start to appear.
There are some other settings that you may want to play around with, especially if your ghosting appears when the screen is dark. They include: “ Perfect Clear,” “Dynamic Contrast,” “Motion Smoothing” or “Noise Reduction.” All of these settings help to enhance the image.
They are added over the raw video footage and can, when they aren’t operating appropriately, cause some artifacts. This is a problem that is usually only found on TVs, but sometimes can be found on monitors as well.
In particular, if you are using an Nvidia monitor, you should go into the Nvidia Control Panel hub and look for a setting that is called “Noise Reduction.” Turn this setting completely off to avoid ghosting or image artifacts.
Another way to fix ghosting artifacts is to check your faulty cables or other devices. Remove all of the devices that are closer to your monitor, including your printer, modem, or even speakers, and see whether or not they have an impact on ghosting. It could be a problem that has to do with proximity.
You may also want to check your monitor cable for any tears, bends, kinks, or rust . Any of these can cause ghosting. If your monitor cable doesn’t look right, you should try to replace it.
If that doesn’t work, you may need to update your graphic card drivers. This can sometimes help with more minor issues or issues that have popped up out of the blue. To do this, you can turn on automatic updates or you can go onto the driver website to get the manual updates.
If you’ve tried both of these fixes and it still hasn’t worked, you may want to check the video port. You will have to take the monitor to a service that replaces it or send it back to the manufacturer if it is under warranty. Replacing this yourself is very difficult.
If that doesn’t solve your problem, it is likely just something caused by your monitor and there is nothing that you can do. Try to choose a monitor that has a pixel response time that is higher. You will just have to put up with the ghosting.
There are some issues that are similar to image ghosting that aren’t actually ghosting, and sometimes those will have other fixes that are much simpler – and sometimes the fixes aren’t as simple.
- Image Retention
This occurs on LCD monitors and, more often, LCD TVs. It is when a faded image is permanently shown on the monitor, whether it is off or not. This isn’t permanent and usually goes away on its own once the monitor has been turned off for a few minutes and turned back on. However, it is a recurring problem. Once it has happened once, it is more likely to happen again and again.
- Burn-In Effect
The burn-in effect looks pretty similar to image retention , but it is something that only happens on OLED displays and monitors. This is, unfortunately, a permanent issue. Once it has happened, there is nothing that you can do to remove the image or even fade it. The best thing you can do is take preventative action and avoid leading the display turned on with a static image for a long time.
- Motion Blur
Motion blur is often called ghosting, but it isn’t the same thing. Instead, it is when there is an image smearing both on the trailing and leading edges of the image, not just training on the edges as ghosting does.
This is a problem that is found on almost every monitor, but high refresh rate monitors (at least those that refresh at 120Hz or higher) have lower levels of blur. The better your monitor is, the less likely there is to be motion blur.
There are also some monitor settings that can help to reduce motion blur, depending on your monitor: 1ms Motion Blur Reduction (LG), ELMB (ASUS), or ULMB (available on Nvidia G-Sync monitors). These will all reduce, but not eliminate motion blur. However, this feature cannot be used while you are also using G-Sync or FreeSync.
- Inverse Ghosting (Corona Artifact)
Inverse ghosting is an image artifact that does look similar to ghosting. It is different in that the trailing object edges are followed by coronas that are bright instead of the smeared look of ghosting.
The artifact is often caused by setting the overdrive option to the maximum level. It is quite easy to fix this problem by either lowering or completely turning off the overdrive settings.
The good news is that monitor ghosting isn’t going to permanently destroy your monitor, even if it may destroy your gaming experience or your movie. Most people have already learned to adjust to some monitor ghosting and issues, even if they don’t exactly love it.
The best thing you can do is research your monitor before you buy it to see if ghosting is an issue for everyone or if it doesn’t have ghosting problems – most reviews will absolutely mention this fact.
