Tuning inmost plasma displays aren't technically televisions, because they don't have a television tuner. Thermotropic liquid crystals are either isotropic or nematic. We think of a crystal as a solid material like quartz, usually as hard as rock, and a liquid is obviously different. Lcd projectors can have problems with darker areas, reducing blacks to a hazy grey and being poor reproducers of shadow detail.
