How to Permanently Fix Ghost Touch on Your Vivo Phone: The Complete Guide When your Vivo phone begins tapping apps, scrolling through menus, or typing random characters on its own, you are dealing with ghost touch (also known as phantom touch). While many guides suggest temporary tricks like restarting the phone, permanently eliminating ghost touch comes down to one definitive rule: eliminating capacitive interference on the screen digitizer . Because smartphone touchscreens rely on tiny electrical charges from your fingers to register input, anything that disrupts or mimics that electrical current will cause the screen to act erratically. Below is the complete, step-by-step method to isolate and fix the root cause on your Vivo device. 1. Disconnect Faulty Chargers and Cables The number one trigger for ghost touch on Vivo phones occurs while the device is plugged in. Cheap, uncertified, or damaged charging bricks and USB cables send unstable electrical currents into the phone, whi...
What is Monitor Ghosting and How Do I Fix It?
Whether you are deep into a fast-paced competitive game or simply scrolling through a webpage, seeing a faint, blurry trail following moving objects on your screen can be frustrating. This visual artifact is known as monitor ghosting. While it is a common issue across many displays—especially gaming monitors—it can almost always be reduced or eliminated with a few quick adjustments to your monitor and system settings.
What is Monitor Ghosting?
Monitor ghosting occurs when a faint trail of pixels lags behind a moving object on your screen, creating an asymmetric smudge or "ghost" image.
To understand why this happens, you have to look at how a monitor works. Your screen is made up of millions of tiny liquid crystal pixels that rapidly change color and brightness to display motion. The speed at which these pixels transition from one shade to another is called pixel response time (measured in milliseconds, or ms). When the action on screen moves faster than the pixels can fully transition, the previous frame lingers briefly while the next frame is already drawing—resulting in a visible trail.
Ghosting vs. Inverse Ghosting (Corona)
It is important to distinguish standard ghosting from inverse ghosting (also called pixel overshoot):
- Standard Ghosting: Pixels change too slowly, leaving a dark or blurry trail behind moving objects.
- Inverse Ghosting: Pixels are pushed too much voltage (usually via an aggressive Overdrive setting) and "overshoot" their target color, creating a bright, glowing halo or inverted trail behind the object.
Why Does Monitor Ghosting Happen?
- Slow Pixel Response Times: If a monitor's gray-to-gray (GtG) response time is slower than the refresh rate window, trails appear.
- Panel Technology: VA (Vertical Alignment) panels offer great contrast and deep blacks, but their pixels transition much slower—especially in dark scenes (often called "black smearing")—compared to IPS (In-Plane Switching) or TN (Twisted Nematic) panels.
- Mismatched Overdrive Settings: Having the monitor's built-in response time setting turned completely off (or set too high) disrupts clean pixel transitions.
- Low Refresh Rates or Bad Cables: Running a high-refresh-rate monitor at 60Hz, or using an outdated HDMI cable that bottlenecks bandwidth, makes motion look choppy and smeared.
How to Test for Monitor Ghosting
Before changing your settings, it helps to have a clear visual benchmark so you can see your improvements in real time.
The industry standard for checking ghosting is the Blur Busters UFO Motion Test (accessible via testufo.com on your web browser). It runs a row of moving UFOs across different background shades at your monitor's current refresh rate. If you see a dark smudge trailing behind the UFO, you have standard ghosting. If you see a bright, glowing outline behind the UFO, you have inverse ghosting.
How to Fix Monitor Ghosting
Follow these steps in order to calibrate your HP monitor (or any modern display) and eliminate motion trails.
1. Adjust Your Monitor's Overdrive (Response Time) Setting
The most effective fix for ghosting is adjusting the Overdrive function built into your monitor's On-Screen Display (OSD) menu. Overdrive increases the voltage sent to the pixels to speed up their transitions.
- Press the menu or joystick button on the back or bottom of your monitor to open the On-Screen Display (OSD).
- Navigate to Gaming, Image Control, or Picture Settings (on HP OMEN monitors, look under Gaming > Response Time).
- Change the Response Time / Overdrive level to a middle setting (such as Level 2, Level 3, Normal, or Fast).
- Avoid the maximum "Fastest" or "Extreme" setting: Pushing overdrive to the highest level almost always causes severe inverse ghosting. Check the UFO test as you toggle between levels until the trail disappears without creating a bright halo.
2. Set Your Refresh Rate to the Maximum Supported Level
Many high-refresh-rate monitors default to 60Hz out of the box in Windows. Higher refresh rates update the screen more frequently, significantly reducing perceived ghosting and motion blur.
- Right-click anywhere on your Windows desktop and select Display settings.
- Scroll down and click Advanced display (or Advanced display settings).
- Next to Choose a refresh rate, select the highest number available for your monitor (e.g., 144Hz, 165Hz, or 240Hz).
3. Enable Variable Refresh Rate (G-Sync or FreeSync)
Enabling NVIDIA G-Sync or AMD FreeSync (Adaptive Sync) synchronizes your monitor's refresh rate with your graphics card's frame rate, stabilizing pixel overdrive across fluctuating frame rates.
- Open your monitor's physical OSD menu and ensure Adaptive Sync / FreeSync / G-Sync is turned On.
- Open the NVIDIA Control Panel (under Set up G-SYNC) or AMD Radeon Software (under Display settings) on your PC and toggle the feature on.
4. Use a DisplayPort Cable Instead of HDMI
Older HDMI cables and ports often limit your maximum refresh rate and prevent Variable Refresh Rate from functioning properly. Whenever possible, connect your gaming monitor directly to your graphics card using a DisplayPort (DP) 1.4 cable or an HDMI 2.1 cable.
5. Enable Motion Blur Reduction (Backlight Strobing)
Many gaming monitors feature a backlight strobing mode (such as HP OMEN Moving Picture Response Time / MPRT, ULMB, or ELMB). This technology rapidly turns the backlight on and off between frames so your eyes never see the pixels transitioning.
- Note: Enabling MPRT/Backlight Strobing usually lowers screen brightness and cannot always be used simultaneously with FreeSync or G-Sync. Turn it on via your monitor's OSD menu if crisp motion clarity in competitive shooters is your top priority.
6. Update Your Graphics Card Drivers
Outdated GPU drivers can cause frame pacing issues, screen stuttering, and improper refresh rate detection. Use HP Support Assistant, NVIDIA App / GeForce Experience, or AMD Software: Adrenalin Edition to install the latest display drivers and restart your PC.
Comparison of Panel Types and Ghosting
If you are shopping for a new monitor and want to avoid ghosting altogether, the panel technology you choose plays the biggest role:
| Panel Type | Response Speed | Ghosting Risk | Best Use Case |
|---|---|---|---|
| OLED | Near-instant (~0.03ms) | Virtually None | High-end gaming, HDR movies, content creation |
| TN (Twisted Nematic) | Very Fast (~1ms) | Very Low | Competitive esports gaming on a budget |
| Fast IPS | Fast (1ms – 4ms) | Low | All-around gaming, office work, color accuracy |
| VA (Vertical Alignment) | Slower (4ms – 10ms+) | Moderate to High (especially dark scenes) | Watching movies in dark rooms, high contrast |
By pairing your monitor's optimal Overdrive setting with its maximum native refresh rate, you can eliminate distracting pixel trails and enjoy sharp, responsive visuals across all your games and daily tasks.
