Detecting secondary display issue

Question

We are facing issue on detecting secondary display from this telpo device actually this device has no secondary display. But from native android sdk it returned secondary display. After factory reset its the same.

Answer 1

As the cash register device, it has data output, whether you have a screen connection or not, in order to support plug in and play, just like the USB port.

If you don't use the secondary screen,you can ignore it.

It will not affect other functions.

Hope this answer can help you！
