Yes. Try it this way
Adj. height so there is some black on top & bottom.
Adj. lin to even out line spacing.
If OK adj. height to fill screen.
Usually you have to do a little at a time going back & forth
between them. They interact. Go a little beyond just filling
the screen. If it has centering use that too. It just moves
the whole pix up & down but does not effect size or geometry.
