How to fix Windows Laptops & Tablets Touch Screen Inaccurate Touch Res

If your Windows computer is experiencing inaccurate touch responses, especially after screen replacement, the most likely solution is to calibrate your touchscreen by accessing the "Tablet PC Settings" in the Control Panel, where you can adjust the touch input and re-calibrate the screen to correct any misalignment issues; simply follow the on-screen instructions to tap designated points on the screen to refine the calibration. 

1. To get started, open the Control Panel and select Tablet PC Settings. If you do not see the option, ensure View by is selected to Large or Small Icons.

2. Or, hit the Windows key and type: calibrate and select the “Calibrate the screen for pen or touch input” result at the top.

                               

3. It will have two tabs if you only have a touchscreen, but if you have configured a pen device, you will have three tabs. In the following example, I only have a touch screen – select the Calibrate button under the Display tab.

4. Next, your screen will go white and display instructions for going through the calibration process. It’s a simple process. A crosshair will appear on the screen and each time you tap it will move to a different spot. Continue through the entire process, and when you’re finished, you’ll be prompted to save the results. The touch screen should now be more responsive and accurate when you interact with it.
