Hello, Ubuntu Community

We want to consult with you for an issue happening on our device which is using ubuntu.

If you select screen size 4:3 when using a wide display, a black area will appear on the left and right sides of the screen where nothing will be displayed (the screen will not be stretched horizontally). At this time, the position of the coordinates (0,0) on the screen is still the upper left corner,not an offset position.When you touch the upper left corner or upper right corner, it is still responding.
I want to know if it is a common issue on ubuntu or not.Do you have any idea?

The display we are using is below
