Touchscreen Troubleshooting
If the touchscreen is not able to access items along the edges of the LCD, it may need to be calibrated. To calibrate the touchscreen,
complete the following steps:
Touchscreen Calibration
Start > Control Panel > Tablet PC Settings > choose Calibrate...You can choose to calibrate Pen input or Touch input.
Perform the point calibrations that appear on the screen to correct the linearity problems.
Touchscreen Sensitivity
The touch screen may start to lose its sensitivity due to foreign particles (such as sticky notes) that are blocking the touch sensors. To
remove these particles:
• Turn off the computer.
• Disconnect the AC adapter cable from the wall outlet.
NOTE:
Do not use water or a cleaning liquid to wipe the touch screen.
• Use a clean, lint-free cloth (you may spray mild, non-abrasive cleaner or water on the cloth if needed, but not on the screen) and wipe
the surface and sides of the touch screen to remove any dirt or fingerprints.
Application Promise
Consistent experience across form factors is what's necessary - a user can download any application from the Windows Store and it runs
great on their machine. There is no application that runs great on one device but not on another. This means developers can target all
Windows 8 and this version of Windows touch devices without worrying about the quality of touch devices depending on the type of form
factor. For example, all Windows 8 touch devices require supporting a minimum of five simultaneous touches. All touch points require
meeting requirements of 25 ms initial touch-down hardware latency and 15 ms subsequent contacts hardware latency. Game developers
can design features based on fast and responsive five simultaneous touch points support across all Windows 8 touch devices.
