1. Mac - Display and Touch Setup

Modified on Sun, 12 Jan at 5:53 AM

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 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.
