Hello, Lets try a few things and see if we can get this ghosting figured out.
- First lets troubleshooting
Do a system search for troubleshooting and select the relevant result. In the new window, click View all from the left-hand menu. From the list that appears, click Hardware and Devices.
Click Next and run the wizard through. The tool will automatically detect issues and then repair them. However, it’s by no means comprehensive and you may need to carry on reading.
- Calibrate the Touchscreen
When your touchscreen is slow to respond or records your touch gestures inaccurately, a re-calibration might be all it takes to bring it up to speed.
Do a system search for calibrate and select Calibrate the screen for pen or touch. A new window will open containing tablet PC settings.
On the Display tab, use the Setup… and the Calibrate… buttons in turn to see if this resolves the issue.
- Disable and Re-enable the Touchscreen
The closest fix to rebooting the entire computer, which should have been your very first step, is turning the touchscreen off and back on.
"Have you tried rebooting?" It's technical advice that gets thrown around a lot, but there's a reason: it works. Not just for PCs, but a wide range of devices. We explain why.
Press CTRL + X and select Device Manager. Left click the arrow next to Human Interface Devices to open the dropdown. Right click the listing for HID-compliant touch screen and select Disable. You’ll be asked to confirm this, so click Yes.
You now need right click the listing again, but this time select Enable. This is one of the simplest solutions, but it doesn’t always work. In fact, you may find that the issue still continues after a system restart. If that’s the case, please read on.
- Update the Drivers
A driver is a piece of software that helps your hardware, for example your touchscreen, communicate with your computer’s processor. Thus touchscreen malfunctions could be due to a faulty driver.
Following on from the instructions above, with Device Manager still open, right click the HID-compliant touch screen and select Update Driver Software….
You’ll want to Search automatically for updated driver software. This will scan Microsoft’s database for any updates available for your touchscreen device. Follow the wizard through as necessary, then restart and see if your problem is resolved.
If not, you should try going directly to the manufacturer’s website, look for their drivers page, select your device number, and download the latest driver.
With this driver downloaded, you may be able to extract it and install it automatically. However, you can select Update Driver Software… again, but this time click Browse my computer for driver software. Use Browse… to locate it, then follow the wizard through.
- Rollback the Drivers
In Windows 10, the Windows Update also updates your hardware drivers. Unfortunately, not all driver versions work equally well. If it’s actually driver updates that are causing the problems, you should try rolling back to the default.
For this, again in Device Manager, right click the HID-compliant touch screen and then select Properties. Then switch to the Driver tab and select Roll Back Driver.
If you know that there’s a specific older driver version that will work, but aren’t able to get to it through rolling back, within the Driver tab select Uninstall instead and then follow the method outlined in step four above.
Windows 10 has automatic updates and you might find that the system keeps pushing the latest drivers onto you — which may very well be the ones causing the problem.
Let me know if any of these steps are helpful or resolved the Ghosting.
