That's not the case here though. If it were, then everybody would just buy the cheap versions!
There are many reasons for more expensive TFT monitors, but the largest is that only one type is cheap - which is the mass produced Taiwan screens. However, these aren't suitable for every purpose - for instance the colour balances are often wrong, the viewing angles are poor etc. etc. Nothing your average user would notice, but no good for a professional.
As soon as you go out of the standard ultra-mass produced bracket you're into completely different territory.
Supply and demand. Supply and demand for cheapy monitors is high, so prices are low due to economies of scale.
Supply of expensive monitors suitable for more professional uses is much lower, demand also lower, hence prices are MUCH higher.
Greed doesn't last long in a capitalist society. There's usually another reason for it somewhere.
