Part of the screen hidden

Hi guys I was wondering if there is a fix to the screen being partially hidden. I am running Emteria on Raspbarry pi 3 b.

oh and my screen resolution is 1366*768

it is the top and left of the screen that is not showing

Did you set the correct resolution in the config? What kind of screen are you using?

Please tell me. how to remove the black bars around the screen? I change the screen resolution but black bars around the screen. right and top of the screen remain. Help prompt please to solve this problem.
