Initial, First, Startup Screen

[B4RTJ]

Dear Team,
Can someone advice how/where to change setting to show full screen when turning on?
At the moment, when I turn on zgemma h7s with remove (from stand-by?) it goes to a small screen with menu selection on the right, and every time I need to press "exit" to get normal viewing mode.
Tried various changes in menu and they even ended in numerous re-flashes as i couldn't re-trace my steps
Thank you in advance.
