It's difficult, if not impossible, to place them behind a couch on a stand and still have a normal-looking image. Because of this, they have to be mounted either on the ceiling, or on a coffee table. These units also typically have an upward throw angle, meaning the bottom of the image is at or above the top of the projector. This means that you can't adjust the height of the image without moving the projector. That might limit which projectors you can buy, as some might not fit where you want them to.Īffordable single-chip DLP projectors typically have very little, if any, lens shift. Now that you've got the basic tech down, it's worth considering where in your house you're going to put the projector. They're all 3-chip designs, so they typically have excellent color as well. Their contrast ratios are significantly higher than either DLP or LCD. These are found in more expensive projectors, even the cheapest being a few thousand dollars. The two biggest manufacturers of LCoS (or liquid crystal on silicon) chips are Sony, as SXRD, and JVC, as D-ILA. In terms of overall picture quality, LCoS is usually the winner. This largely varies per projector, however. They're all three-chip designs, as in there's a separate chip for the red, green and blue components of an image, so it's possible for them to have better color compared to many DLP projectors, which usually rely on a spinning color wheel. Its Home Cinema 2150, for instance, had a better contrast ratio than many competing DLP projectors. However, Epson has come a long way in recent years. It's just harder to get a good black level with LCD, something that's true with TVs as well. Lower-end models typically have very poor contrast ratios. There's still a lot that can be tweaked.įor LCD, Epson is by far the biggest name. That all said, two DLP-projectors that cost the same, but are from two different companies, are going to look more similar than different. Others might use the base reference design, and then tweak it to their specs. Some companies just use a reference design and slap their name on it. How it's implemented in a case, the overall airflow, what lamp is used, how the settings are tweaked and more, are often done by the projector maker, aka the name on the outside. ![]() This includes the chip and the color wheel (to make all the colors you see). Every DLP-based projector uses a "light engine" made by Texas Instruments. Despite dozens of companies making projectors, the chips are almost all made by just four companies. The image chips are one of the most confusing, but also most interesting, aspects of projectors. Color is often very good, but that's more to do with being found in higher-end projectors.Mid- to high-end projectors including Sony and JVC.Color can be better than most DLP projectors.Budget to midrange projectors, mostly from Epson. ![]()
