Erm, but it's not a user calibrated setting, it's a factory calibration i was referring to
For example:
Do they do runs of these? i.e. they calibrate a handful of monitors then run a production of these.
Or
Do they factory calibrate every monitor that comes off the production line.
(not being difficult here, i'd like to know as i'm considering getting a 2nd hadn Dell P2415Q which i know are calibrated at the factory, but a bit weary if a reset takes it before calibration - you never know what someone has done to the screen since owning).
Well, as far as I know based on what I saw on a television documentary programmes, typically it goes like this...
Make them in a production line (call it Model-A), but they are not fully finished, usually just the screen, chips, power supply, and buttons, but no outer cover. (Image C-P3O in
Star Wars: The Phantom Menace.)
Test every one of them, and likely to calibrate every one of them to the same standard setting, which is applied to all models in the same production line.
Monitors that passed the test and correctly calibrated will then be finished off in the production line. (Usually just putting on the outer case.)
People buy a monitor, all of the same brand new production line monitors are at the same calibrate settings, over time each person re-calibrate to their liking.
If someone decided to sell or give away the monitor, and you buy it, then reset it to factory setting. It will be reset to the same standard calibrate settings as at that time of the testing and calibration stage.
Company decided to make a new model, call it Model-B. Then they start making them in production line (same as they would with Model-A)
But when it comes to testing stage, I can't be sure if they calibrate them to same standard setting. It is likely that Model-B will have its own standard setting which could be a little different to that of Model-A. Maybe because Model-B's LEDs are new and better than Model-A's LEDs.
If you buy three monitors, all are Model-A, they all will look the same. If you buy two Model-A and one Model-B, then either Model-B will look same or different.
But I don't think each different monitors in the same production run (ie Model-A Series Number 001, Model-A Series Number 002 etc) have their own calibrate settings.
(That would be like saying in a car production line, one car is set to a maximum speed of 95mph, yet, the next car in line, which is same model, is allowed to be modified to have a maximum speed of 100mph.)
