Can I endorse Stuart Walker's recent comments on this. We have seen
various Fresnel and other type enlarging screens over the years. It
is simple common sense that the total screen area cannot increase as
the lens simply sits over it and any of the lens outside the screen area
would offer nothing at all. Thus, if the areas near the centre of the
field are magnified, those near the periphery will either be lost or
badly distorted. With a television picture in which the action is
usually confined to the mid-areas, this may not matter, but on
aWindow's screen this would be disasterous for the partially sighted.
Such devices could never compare with using a combination of larger
monitors together with Window's own character and icon enlarging
facilities.
