LCD vs. DLP - Home Theater Projectors

There are several criteria for choosing between these two technologies, the purchase of a home theater projector. Ergonomics is a key sector. In lower price ranges LCDs generally have a great advantage in this category, including their wide range of zoom lenses and lens shift. Other key issues how to get great black levels so you can see details in dark scenes and not have large areas bleak future as a large flat space with no details.

 
DLP Projector

Elements such as the DLP rainbow effect, for a small percentage, and the effect of Port LCD screen, which limits the distance that you can sit on the screen using an LCD projector, key factors in determining other. We will also continue Techologies - usually called "AI" for artificial intelligence, which became more frequent. There are great advantages for the use of "AI", but also some disadvantages. In this section we will try to explain some of them. Color accuracy is obviously important, but not a crucial difference between LCD and DLP projector. Bright varies from one model of projector, but neither technology is inherently brighter.

 LCD Projector

The LCD models are usually more user-friendly, offering the widest zoom lens , making it easier to position in the room. They also tend to offer the lens shift function that allows flexibility in how high or low to mount the projector and screen. LCD projectors typically on offer movies from 1.5:1 to 2:1 to enlarge their will. Translated: 2:1 means that you can adjust the image size, so the more you can position the projector to fill a screen size is half the distance to the farthest.

This position provides for sufficient flexibility, generally put the projector anywhere half-way back room for wall mounting (depending on screen size and room size). With DLP, the zoom range of 1.2:1 to 1.4:1 is usually much less allowing investment options. Consequently, there are people who eventually buy LCD projectors, simply because not only competing DLP projectors work in their room.

The other key difference is that I mentioned lens shift. Virtually none of the DLP projectors selling for under $3000, offering at the time, while nearly all LCD projectors selling for $1,500 or more to offer. Lens Shift allows you to place the projector in a large vertical interval. Almost always ensures that you can get anywhere by placing a rectangular image with the bottom of the screen, even with the top. With some models, you can start well below the bottom and go far beyond.

DLP projector design is less favorable to the use of lens shift, and thus only the more expensive DLP models offer it at this time. The end result, the projector without lens shift must be a certain height on the screen. Usually, about the same, or just below the bottom. That may change, but a new home theater projector, the Optoma HD72, usually sits a foot to a foot and a half below the bottom of the screen or an amount, when mounted on it. If you do not place the projector at the correct height, you get a trapazoidal pics, which can be corrected with digital keystone correction. Unfortunately, the key image correctionadds visible and should be avoided.

LCD panels with intrinsically less contrast of the LCD home theater projector manufacturers Amnesty International added. Bingo, the new high contrast ratio. DLP Now, in the endless war are also specific to add artificial intelligence to their projectors, we now see as home theater projectors today with claims as high as 7000:1 4500:1 for LCD and DLP. Move Award recently, for example is now 10:000:1 a claim against the BenQ PE8720 DLP Projector.

DLP projectors also create SDE also use the services because of the fixed pixel. The DLP chip, creates pixels, however, are much less visible than LCD. I would venture that you would normally sit closer to the front row at the cinema to detect SDE with a DLP projectors.
