- Why do some screens get set up that way by network providers? Is
it common? I am presuming its either to get better performance
out of an older LCD screen or easier to see text on a new large resolution
monitor? Do you regard it as OK or not good practice? Is it
common enough that we have to cater for it?</span><o:p></o:p></p>

- I have one program that has a reasonable amount of internal settings done to
scale the forms to fit available screen resolution - Note I do not use the form
align or anchors as I prefer to to keep the horizontal and vertical proportions
and expand the form to fit about 3/4 of the desktop, using Form.ScaleBy.
This has the advantage of increasing the size of buttons and keeping the
relative sizes of everything the same. I also tweak the row heights and
font size of grids up by the same factor, all works fine except on 120DPI where
it all goes awry mainly with row and font height size in grids, and
sometimes the ScaleBy does not happen (I presume its getting values it can't
use). and I am not quite sure why. I am detecting the
screen.height, screen.width, Screen.PixelsPerInch, and
form1.pixelsPerInch so I should be able to get it right.</span><o:p></o:p></p>
