The current software version of the DM smart App does not allow for full screen mode. Nor does it allow to re-size the window.
Unfortunately this can result in having to scroll down to see the bottom of the window. Especially if you are on a smaller notebook size laptop.
In order to not have to scroll down, your computer display will need to have a minimum of 900 pixels vertically. So the lowest option should be either 1440 x 900 or 1600 x 900.
This WILL GET FIXED in a future software version.
