Auto centre
It is common for the image to be off-centre in Amiga programs. To help
position each program’s image in the centre of the screen
Auto centre
can be
enabled.
Enabling
Auto centre
will cause
THEA500 Mini
to continually monitor the
position of the image and alter it accordingly, which is most often a vertical
adjustment.
Enabling this option can sometimes result in the image appearing to slide
into place towards the centre of the screen, where it will usually stay. For the
few programs that this happens frequently to, it may be preferable to instead
configure a fixed
Vertical offset
along with a
Crop
rectangle.
Crop rectangle
To maximise the size of the image and remove the unused and unnecessary
black borders at the top and bottom of the screen, a
Crop

configured to define the region of the image that
THEA500 Mini

THEA500 Mini
can perform this configuration automatically, and is described
The remainder of this section describes how to configure the
Crop
rectangle
manually, in case you want to make any fine adjustments.
