Bauhn 9.7" Tabler - Layout setting

Purchased a Bauhn 9.7" Tablet (AMID-971R) but it does not have all the details I need.

Display Size: IPS 9.7" 4:3

Display Resolution: 1024 x 768

Is there a way to work out with code what the DPI is in the Tablet?

There are no standard Layout in the Designer for this resolution and need to create the correct ones for the Tablet.

Also need th einfo for the Virtual Device?

Thanks.
