The question I have is do the 19"+
Supermac/Radius type
monitors have such a bad design that they lasted only a few years? How do
early 1990's monitors of that size compare to the monitors that came before
and after them?
I'm most familiar with DEC monitors of that size range (17", 19", and
21"),
my impression is that the electronics (with a few modifications, such
as no sync-on-green) were sold under other badges in that same era.
While some of the generics (e.g. Idek) were superior to the DEC-branded
units in reliability, it wasn't by a whole lot, and I think that my
perception of reliability may be twisted by the fact that the generics
came a couple of years after the DEC-branded ones.
Realistically, yes, they lasted 3-4 years in their prime in 24x7
usage. And they were big-ticket items at the
time too (list price in the $900-$1500
range) so typically they were repaired/refurbed and returned to
service. Typically they would go a couple of cycles like this before
they suffered a really catastrophic failure ("letting the smoke out").
Where I have worked we have literally hundreds of 21" monitors, most
on 24x7. Only a few DEC units from the early 90's have survived to
today. A few more Ideks and other generic units from the mid-90's.
Most of these pre-1996 units have seen at least one repair/refurb.
The Dell-branded monitors from the late 90's are generally still in
service, although some have obvious CRT blooming. We also have
lots of black Dell-branded 21" monitors from the last couple of
years.
