Flat-panel LCD television
Large-screen high-definition televisions are currently all the rage. Not only do these TVs come in different sizes, but they also come in different technologies: LCD, plasma, DLP and projection.
Portability
DLP TVs are very large, and while not as deep as a tube TV, do have some depth, thus they are not really portable. LCD projectors are compact, and light enough for a person of average strength to carry.
Contrast Ratios
Both DLP TVs and LCD projectors provide good to excellent contrast ratios. It can be difficult to accurately determine the contrast ratio, and manufacturers tend to display data that make their products appear to be the best.
Screen Sizes
DLP TVs can be very large, some over 80 inches diagonally. LCD projectors can produce viewing areas that are much larger because as long as they produce enough lumens, they can produce an image the size of a typical living room wall, but this relies heavily on the presence of a very bright bulb.
Brightness
DLP TVs generally produce a visible image regardless of lighting conditions, whereas an LCD projector may appear bright enough only in a darkened room. Higher-lumen projectors overcome this weakness.
Cost
An 80"+ DLP TV will cost about $3,000 to $4,000. A high quality LCD projector with high lumen output and high contrast will cost roughly the same.
