The LCD market nowadays is a real scam for many consumers.
The specifications of LCD displays don't include all necessary information, retail store locations aren't educated enough to be able to sell the products.
For example, many LCD displays can only display native 6-bit color(per channel = 18bit). But at the same time advertise that they display 8-bit(per channel = 24-bit total) because they add some software to simulate the colors.
Even when buying high-end monitors like Dell's 24" widescreen UltraSharp, consumers have to be careful, because Dell changes the type of panel they use in the monitor all the time. So you could order a display today, and another in 2 months, and although they have the same model number (aside from some strange code at the end) and specs they are different panels, and look fundamentally different.
Perhaps we need some sort of standard for rating LCDs, so that the average consumer will know exactly what they are getting.
