Vehicle and Desk Dock

Last edited by March 17, 2015

The M101B is shipped without VGA driver pre-installed, and therefore the VGA driver has to be installed first before using the dock's VGA output. For driver installation, please refer to the docking driver installation guide for detailed installation and setup information.

The M101B's default external display setting for the VGA output is mirror mode, and only under mirror mode would the touchscreen on the M101B operate normally.

Yes, the M101B's external display setting can be changed and saved to use extend mode. However, under this mode, it is recommended that the user operate M101B with keyboard and mouse as any touch operation on the touchscreen would correspond to the external display.

This is normal when the docking supports VGA output and the VGA driver (USB to VGA) is installed. When the tablet detects the VGA function on docking, tablet built-in graphic driver will adjust the graphic settings to display image over the VGA output, and cause the screen turning black for a second.

This symptom also happens when the VGA output is well installed with docking but no physical external display connected.

This is normal when docking VGA driver is installed on M101B without proper setup. Under the default mirror mode setting, display resolutions for both tablet built-in screen and external monitor will be the same. If the external monitor's resolution is lower than the built-in native one, the tablet built-in display will sync with the lower resolution and thus not filling whole screen. The side effect for this issue is that, when the built-in display is not fitting the touch active area, the touch controller will not be able to calculate correctly and leads to incorrect positioning.

This symptom also happens on M101B when VGA output is well installed with docking but no physical external display connected. Under this situation, the tablet built-in display resolution will sync to docking VGA default setting, 1920x1080, which is with different ratio from M101B's built-in display.

To resolve this problem, user should change M101B's built-in display setting to fill screen instead of keeping aspect ratio. For detail information, please refer to the docking driver installation guide for installation and setup scenarios. The settings will be saved automatically for next use.
