What are the advantages of a profile projector?

LCD projectors are a popular choice for several reasons, really. LCD projectors can be outfitted for any projection purpose; from portable projectors weighing only a few pounds to large venue projectors for theaters weighing several hundred pounds. LCD panels can be cheaply manufactured as well, and that keeps the cost of LCD projectors very low, and LCD projectors are some of the brightest projectors on the market. While LCD projectors are very popular, they have some issues that some users can find annoying. The most common problem users have with LCD projectors is small lines that form grids between the individual pixels of an image. This is commonly referred to as the "Screen Door Effect" because it can be like looking at an image through a screen door. While this also creates a sharper image with less blur, and when displaying data or still images, it's usually not a problem. Usually, this screen door effect is most noticeably seen in video and moving images as well as closely examining an image. The other drawbacks of LCD projectors sometimes are dead pixels. If one of the millions of tiny little pixels dies, it will often project a square that does not change colors on the projection screen. It can be distracting to the projection audience if there are several of these dead pixels spread out over the screen, but it is usually a problem associated with the age of the projector, and most projectors can go for years without a single problem. Historically, there are several other problems with LCD projectors such as "ghosting" also known as "motion blur" where an image will stay on the screen after it had changed and causes a blurry picture momentarily, as well as having poor color saturation and contrasts. However, in recent years, these issues are pretty much non-existent since the technology has evolved and is continuing to evolve. Possibly in the near future, even the screen door effect and dead pixels will be non-existent as well.
