A

Question

I touched the screen, but the coordinates do not match.(How to Setting Display Scaling mode)

Answer


Twomon SE uses virtual hid device (touch, pen) and it is mapped to the display device with 1:1 mapping.
Since touch(stylus) input is calculated based on current display's scaling method, in order to use it properly,
we need to set the same scaling mode in tray menu as specified in the gpu's display settings.

Question

When running Twomon PC Program, asks for a microphone access.

Answer

Microphone access is required during the Twomon PC Program to change the audio device to support sound output.
If you deny access to the microphone, the sound features supported by TwomonAir may not work.
In addition, TwomonUSB does not support sound function, so even if you deny access to microphone, it works normally.
Actually, it is not related to the function to control the microphone device, so please use it with confidence.
