What Is Monitor Ghosting and How Do I Fix It?

Imagine a walking ghost. When a ghost walks in those horror stories, a weird trail follows. No, your computer is not haunted if you notice smudge-like, eerie effects, resembling the ghost trail, on your screen. It is a computer monitor ghosting.

Nothing to do with the paranormal world, screen ghosting on laptops, especially Dell monitor ghosting, is a common issue many users encounter. You can spot an ethereal trail behind fast-moving objects on your screen, particularly on LCD monitors without fast refresh rates and technologies like G-Sync and/or FreeSync for adaptive frame rate synchronization. The refresh rate is the number of times per second your monitor updates with new information, usually measured in hertz (Hz). Higher refresh rates help make motion look smoother and reduce ghosting. Adaptive sync technologies, like G-Sync or FreeSync, work by keeping your monitor’s refresh rate in sync with your graphics card’s output. This prevents mismatches that can lead to ghosting, screen tearing, and stutter during fast motion.

While not uncommon, scary PC monitor ghosting is easily fixable. This article guides you through the most effective ways to fix ghosting on the monitor and prevent its occurrence in the future.

Before proceeding to troubleshooting and future prevention, let’s shed more light on computer screen ghosting to help you identify and fix it more accurately.

What Is Computer Monitor Ghosting

Ghosting is the monitor smearing or smudging. Meaning, monitor ghosting is the smear or smudge that you see behind the objects moving on your computer screen. It appears like a dark and discolored trail or blur outside a moving object’s boundary. Depending on what caused the computer screen ghosting, it may also look like a bright halo effect.

The bright-colored halo ghosting effect on the monitor looks more prominent when objects on the monitor move quickly. One of the most common ghosting monitor examples is the effect noticed when playing video games, watching live sports, or in scenes where dark and bright elements exist simultaneously.

Moreover, the ghosting effects are also commonly experienced in action movies with fast frame transitions or when scrolling high-contrast text, for example, colored text on a dark background.

While LCD monitor ghosting is common on any form of LCD panel, you can more commonly spot it on VA-type panels. While image ghosting in the monitor is much less common in OLED panels, self-emissive displays can show temporary effects on static elements, such as news tickers or health bars.

Additionally, IPS screen ghosting is also common. IPS panels, which stand for In-Plane Switching, are known for delivering excellent color accuracy and wide viewing angles, making them a popular choice for design work and general use. However, IPS technology usually has slower response times compared to other panel types. This slower pixel response can cause visible ghosting, especially when displaying fast-paced action, such as in gaming.

For comparison, VA (Vertical Alignment) panels are another common type of LCD display. VA panels are often preferred for their strong contrast ratios and deeper blacks, which are great for watching movies or working in dim environments. However, VA panels typically have even slower response times than IPS panels, making them more susceptible to ghosting, particularly when there is fast motion on screen. Understanding the differences between these panel types can help you identify or troubleshoot ghosting issues on your monitor.

As for the causes, many factors may contribute to PC monitor ghosting. Let’s discuss the key ones in the next section.

What Causes Monitor Ghosting

The LCD monitor ghosting occurs because of the monitor’s low refresh rates or slow response times. The monitor struggles to keep up with the action on your screen.

When the monitor screen refreshes, the physical pixels cannot match the speed of the fast-changing images, causing image ghosting on the monitor, i.e., blurred objects with a faint or ghostly boundary. The issue gets worse when frame times, i.e., when a new frame gets delivered, are faster than the response time of your screen.

When a new image on the monitor screen is dependent on its refresh rate and slow response times, it can cause PC monitor ghosting. For example, when a 60Hz refresh rate refreshes images 60 times per second, it displays a new image every 16.67 milliseconds.

In this case, if your monitor has a response time slower than 16.67 milliseconds, the pixels will continue transitioning colors in the new frame, creating a ghost boundary behind the objects moving on the screen. VA panels have slow response times, making them more prone to ghosting.

To sum up the causes of PC monitor ghosting, here are the factors that may have contributed to it.

• Poorly optimized or incorrect brightness, contrast, or sharpness settings
• Radio waves from other devices are interfering with your monitor display
• Too high overdrive settings configuration
• Slow monitor response time, VA panel technology, and low refresh rate
• Outdated graphics or display drivers

Having identified the causes of PC or laptop screen ghosting or pixel trails, you may also want to confirm ghosting on your computer. Hence, testing for monitor ghosting is next in this article, before you can fix it.

How to Tell If You Have Ghosting in Your Monitor

You can test the presence of computer monitor ghosting in these quick and easy steps.

• First, navigate to Blur Busters UFO Motion Test to start the assessment.
• Wait for the test to be completed.
• Review the test results.
• If you see green, there is no monitor ghosting. If you see an orange alert, there are ghosting issues and ways to fix them.

Since ghosting on the monitor’s effects range from eye strain and headaches to motion sickness because of the difficulty following the on-screen action, fixing this problem is essential.

How to Stop PC Monitor Ghosting

You can fix monitor ghosting by changing the refresh rate, enabling your monitor’s overdrive function, updating graphics drivers, replacing faulty cables and peripherals, changing the monitor’s response time, activating G-SYNC/FreeSync, and changing the display settings of your monitor. Here are all these solutions explained in detail.

Fix 1: Change the monitor refresh rate

A low refresh rate may be more prone to ghosting. Hence, if you are using a VA panel or your monitor’s refresh rate is too low, below is how to change it to fix ghosting on the monitor.

• First, click the Start button, type Display Settings in the search bar, and then select Display Settings from the search results.

• In the Display Settings, scroll down and click on Advanced Display.

• Next, select the monitor for which you wish to adjust the display settings if you have multiple monitors.
• In this step, click the Choose a refresh rate dropdown and change the refresh rate to a higher rate. For the best experience, choose 144Hz or 120Hz.

Fix 2: Activate the overdrive function on your monitor

The overdrive function speeds up your monitor’s refresh rate and lowers its response time, helping the screen pixels with faster color change. It is also known as OD, Response Time, and TranceFree, depending on your monitor manufacturer. If confused, search your search engine (for example, Google) for your monitor’s brand, model, and overdrive to learn what your manufacturer calls this function, and then follow the steps below to enable it.

• Use the physical buttons on your monitor to open the on-screen display (OSD) menu.
• In the OSD menu, go to Overdrive, Response Time, TranceFree, or a similar section.
• Change the Overdrive or response time setting to Fast or If there is inverse ghosting or a bright halo, apply the next lower setting, as a high overdrive can result in new artifacts if it is too high.
• Lastly, save the changes you have made.

Fix 3: Update graphics drivers

A graphics driver is a piece of software that helps your graphics card and operating system communicate with each other. An outdated graphics driver may lead to several issues, with computer screen ghosting being one of them. Hence, below is how to update the graphics drivers.
