Luckily, these Eizo screens are made to last. With the calibration
features it offers, the picture's is as good as new after 14608 hours
of use. A low-end monitor would almost have reached its MTBF by
now...

Is a ViewSonic a low-end monitor? Mine is about 5 years old, gets two to
three hours' (at least) use each day, and is running fine. I have no
intention of buying an LCD display until this monitor fails (or I buy my
next computer).

There was a time when Eizo was pretty much _the_ monitor to own. It is not
longer a highly visible brand, at least not in the US.


With some luck, SED screens are available when this monitor dies.
The technology exists, but there are license issues.

The current consensus is that the license issues will not be resolved and we
will never see SED displays.

I've wondered why we haven't seen much in the plasma-based computer
displays. I can think of a number of reasons, including limited resolution
for a given screen size and significantly higher power consumption.


SED is still a fixed pixel grid, but at least works on the basis of color
addition (like your eyes!) as opposed to color polarization and
subtraction.

Way incorrect.

All current LCDs use additive color. Some years back there were LCD panels
for transparencey projectors that used subtractive synthesis. This allowed
significantly higher resolution, but had no other advantage I can think of.

If you want to get picky about it, subtractive systems are "additive" in
that (for example) the yellow layer -- and only the yellow layer -- controls
the amount of blue light in the image. The blue light passed by the yellow
layer is "added" to the green light passed by the magenta layer and the red
light passed by the cyan layer. (This is all semantics, of course. I'm
making a point, not trying to "prove" something.)

I have no idea what you mean by "color polarization". The polarized layers
in an LCD are _not_ used to create colors (such as the colors seen when
placing plastics between crossed polarizers).
