A button behind the wheel enables quickly changing the pointer speed to suit different tasks: select higher speed (higher DPI) to make the pointer move faster for general use; select lower speed (lower DPI) to make the pointer move slower and more precisely for drawing, photo editing, etc.

VM4L-Improved thumb rest

Improved thumb rest

The thumb rest has been reshaped to provide even more comfort over earlier versions.

VM4L-Pointer speed indicators

Pointer speed indicators

Up to four lights show pointer speeds from slow to fast: slow speed or low DPI for precision work such as photo editing or drawing; fast speed or high DPI for quickly moving across the screen for general tasks.

Compatibility

Windows

▪ Downloadable driver for Windows XP, 7, 8 and 10 in 32/64 bit for programming all 6 buttons. The driver is not required. The VerticalMouse 4 still has basic functionality without it.

▪ Freeware driver for other Windows versions at www.highrez.co.uk/downloads/XMouseButtonControl.htm (Evoluent has no business relationship with this vendor.)

▪ USB only; not compatible with PS2 adapters. May be compatible with some USB KVM switches but it is not guaranteed.

Apple Mac® OS X 10.5 to 10.14

▪ Includes Mac driver for configuring the buttons. The driver is optional but highly recommended. VerticalMouse still has basic functionality without the driver. Some functions of the Windows driver are not available in the Mac driver.

Apple Mac® OS X 10.15 and newer

▪ Due to recent Mac OS update, our driver must be updated to maintain compatibility. We need a driver development kit from Apple but they have not replied to our request even after repeated emails. Therefore our driver development is unable to proceed. We apologize for the delay and will continue to contact Apple for the resource. Alternatively, the third party software USB Overdrive www.usboverdrive.com may be used to program the buttons on VerticalMouse. (Evoluent is not affiliated with USB Overdrive.)

Linux

▪ Basic functionality without a driver.

Unix

▪ Compatibility unknown.
