2. Display and Touch Setup on Mac OS

Important information on how to setup the display and touch function for the Mac.

1. Mac - Display and Touch Setup

Display configuration on the Mac (all models)

The resolution of the monitor should be set to 1920 x 1080. 

If it is not set automatically by the OS, you can set it manually under Settings > Displays.

Set the monitor as an external display in Displays on the Mac. (not mirror)

The monitor frequency should be automatically set to 60Hz. 

In some cases, the Mac OS may set it to 75Hz and this will cause the display to not be able to show any video. The refresh rate settings on MacOS are hidden — In Display Settings, be sure to hold the Option key when clicking "Scaled" to see the refresh rate option.

Model 1A+/2A Touch Function

The TouchScreen should show in the System Report under USB

If it does not show up in the System Report, it is due to a connection issue. 

Connect the USB-A to USB-C cable provided directly on the Mac. (not through a hub or docking station or the Y-cable) and reopen the System Report. 

For further troubleshooting see here.

If the touch works but affects your other display, then you need to move the mouse pointer to the MP Controller display. This can be done automatically when you touch the MP Controller display instead of manually having to move the cursor by using UPDD.

Additionally, here are some other utilities that can move the mouse cursor to other displays.

Model 1A Touch Function

The Touch hardware shows as "Multi-Touch by G2TSP" in the System Report.

UPDD is required for touch functionality on MacOS Catalina and later for Model 1A. See here

If it does not show up in the System Report, it is a connection issue. Connect the cable provided directly on the Mac (not through a hub or docking station or the Y-cable) and reload the System Report.

Using a stylus with the touchscreen:

The touch screen does not work a stylus but it does work with pens that have a rubber tip.

These are Capacitive Stylus Pens, as this one



2. MacOS Full screen mode and Window mode

The MP Host plugin can operate in Full screen mode and Windowed mode.

You can select this option from the right click menu

We recommend running the MP Host "In Window" mode and disable the MacOS top bar for secondary displays via Mission Control, Spaces. See how to do this here

If Spaces is not disabled then "In Window" mode will show up the top bar of Mac OS on top of the MP Host window.


If you run the MP Host in Fullscreen mode, then the top bar will not show up on any display.

3. Stylus pen for the touch screen

You can use a stylus pen made for capacitive touch screens. This pen has a rubber rounded end like:

4. Mac - Hide the MacOS top bar from the MP Controller

In Mission Control, under System Settings, disable the option: "Displays have separate spaces"
Choose "Log Out..." from the Apple Menu
Log back in as you would normally. 

See tutorial video on YouTube

5. MacOS Dock appears on the display of the MP Controller

If you place the displays on top of each other (Display arrangement) Mac OS places the dock on the bottom display 


This is done by Mac OS and it happens with all displays.


If you arrange them side by side then the dock can be placed on either display.

6. Select the target monitor for the MP Controller

The first time you load the MP Host plugin, it will be displayed on your main monitor.

You need to select the target monitor from the big window of the MP Host plugin.

Right click anywhere on the main black area of the big window and from the menu under Monitor, select the target monitor which will be the last monitor in the list.
