You can adjust screen calibration with any Amlogic Android box with the Projectivy app as this has those extra settings.

This was recently discussed regarding the Onn devices but same will work on this device because it has Amlogic CPU.

How to Adjust Onn Android TV Box aspect ratio (scaling)

I have set up an Onn 4k steaming box using Troy’s instructions. Everything works fine except that the aspect ratio on side loaded apps are totally off, and I don’t know what to do. Any help would be gratefully appreciated.

If you installed the SlimBoxtv ROM onto the device the same type of setting should be under the SlimbBoxtv extra settings/features area. Don’t have that device with me right now so can’t point to exact location but I do know that feature is available when you flash that ROM.
