Sorry what i meant was, even with the same brand and manufacturer, might there still be slight differences in viewing angle depending on how well each individual monitor was made/calibrated? My point being that, as cool as the idea is, mightn't it be impractical if you have to test/calibrate every monitor that's used, versus a manufacturing process that takes the usage into account from the beginning.
