AW: filmscanners: Puzzled about display resolution

["Elmar Pinkhardt" <ElmarPinkhardt@gmx.de>]

To be more acurate about physical resolution:
It is quite simple to calculate and I won't tell you anything new:

If you have a monitor with a maximum dot pitch of 0.24mm and a viewable
image area of 406*305 mm (these are the specs of the Hitachi CM823F) your
maximum physical resolution is horizontal  406/(1/0.24)= 1691
So 1691*x is what you get.
Even if you say that its average dot pitch is somewhere about 0.23 mm you
don't get 1856*1392.
You can't get anything more without loss of image quality, even if the
fairytales of most manufacturers try to tell you something different.

By the way, what do you really win out of a higher resolution? The palettes,
the fonts, the icons are smaller  but the viewable area remains the same. To
look at an image in full screen mode in PS you just have the monitors
viewable area as the limit either with 1280*960 or 1600*1200.

The one thing is what monitors are able display the other thing is what they
are physically able to display, that is dependent of the dot pitch. To be
able to view real 1600x1200 you need a 21' with  something about 0.25
dotpitch.
The "high-end" Hitachy has a maximum dotpitch of 0.24. So you will get
something more than 1600x1200 physically but I think you won't get
1856X1392. (Somewhere I have the formula to caclculate it correctly, but I
can't find it at the moment). IMHO all the specs by the manufacturer like
2048*1536  (like Hitachy or Iiyama) just says that out of the highest
possible refresh rates it is POSSIBLE to run these resolutions, if it is
usefull is a very different question.
Running more than the physically possibe is like having a midrange flatbed
scanner that "is able" to scan with 2400 ppi, you will loose detail
sharpness.
