Hello fellow owners of the Chuwi Vi8 tablet.
When reinstalling Windows 8.1 there is an annoying driver error which can occur which causes the calibration on the touchscreen to no longer function correctly. It will register taps but not in the correct spot on the screen.
This error can be resolved by installing the correct drivers in the correct order.
The Intel(R) HD Graphics display driver needs to have been installed on the tablet before the KMDF HID Minidriver for Touch I2C Device which runs the touchscreen.
If you are having the error where the touchscreen is not calibrated properly:
go into Device Manager and uninstall The Intel(R) HD Graphics display driver, check the box to delete the driver from the system
continue in Device Manager and uninstall the KMDF HID Minidriver for Touch I2C Device driver, check the box to delete the driver from the system
Install the Intel(R) HD Graphics Display driver from the pack available at: http://techtablets.com/chuwi-vi8/downloads/ (Chuwi Vi8 Win8.1 Drivers April 2015 79.1 megabytes) and reboot the tablet
Install the KMDF HID Minidriver for Touch I2C Device_11.59.20.989_x86_non driver available at: https://yadi.sk/d/SleAozlXdtSAJ in Nori_Win8.1_Driver_S801_S805_S895_S105_v150110.1_Stable.zip (subdirectory Nori_Win8.1_Driver_TP10_VI8_150110_Stable / 1_Other / KMDF HID Minidriver for Touch I2C Device_11.59.20.989_x86_non) and reboot the tablet
Touchscreen ought to be calibrated properly after these changes
Enjoy!
