Why don't the factories ship sets already calibrated

Archived from groups: alt.tv.tech.hdtv (More info?)

I've seen several post of people talking about having their TV's calibrated.
I've even heard some, like some sony sets, pretty much have to be
calibrated. This leads me to wonder, why don't they calibrate them at the
factory before shipping them?

They do. They're calibrated for brightly lit showrooms. And they do it to
all of them, since they don't know which ones will be used for display.
Their objective is to SELL sets...not make life easier for you.

More accurately, they are calibrated to produce an attention-getting
bright extremely colorful picture (as opposed to natural levels of
brightness and colors). The fact that this also leads to premature
failure of the display (although safely out of the warranty period!) is a
feature, not a bug, to the manufacturers!

That's really only an issue on RP CRT sets. LCD, DLP, LCoS, Plasma are
really immune to convergence problems. But it's a great point for the
CRT sets still being distributed.

I think the real point is that TVs are not professional equipment, and
as such, they are not built to professional standards. Given that,
every set would have to be individually calibrated. And that would add
much time to the manufacturing process. Plus, the point another poster
made about running the set for 100 hours before calibrating is valid.
Professional monitors are very expensive given their size.
