LCD vs. DLP
There are several types of projectors available on the market these days. The two types that are typically put to commercial use are LCD and DLP projectors. So, when choosing a projector for the office, you will probably be looking at these two options.
How do they differ and what do they have in common?
DLP projectors tend to be smaller and less expensive than LCD ones and project primary colours in sequence and not simultaneously. Their smaller size allows for easier portability – you can move the device between offices and conference rooms, and the lower price makes it more affordable for small businesses. They also tend to offer better contrast and juicier colours. One typical complaint with DLP projectors is the so-called “rainbow effect”: a shift in colours that come people may see when there is movement on the screen or if they shift their gaze. It depends on your sensitivity to the effect, but those who do see it may find it annoying for long term presentations.
LCD projectors come without the “rainbow effect”, but also with a bigger size, heavier weight and a heftier price tag. Compared to DLP, they have been known to offer a sharper image and deeper black levels, but when it comes to business use, the difference in image quality may not be that visible.
Summing it up:
– DLP projectors: smaller, less expensive, possible “rainbow effect”, sharp colours
– LCD projectors: larger, more expensive, sharper images, deeper black levelsLight output
The brightness rating of most home theater projectors is 700-2500 lumens (Projector’s light output). All projectors provide sufficient brightness that allows you to watch movies in a darkened or dimly lit room. In a situation where your house has a lot of lights, it is important for you to look for a projector that has a high brightness rating. Additionally, high brightness ratio will also help if you intend to project the image onto a wall or you intend to display an extra-large image.
Here’s a guide:
500 – 1000 lumens: suitable for a 5' – 6' (152 cm – 183 cm) diagonal screen in a small room with about 5 – 10 people and no lighting
1000 – 1500 lumens: works well for a screen of about 8' – 10' (244 – 305 cm) in medium-sized room with about 10 – 30 people and dim lighting
1500 – 2000 lumens: best for larger screens of about 12' – 25' (366 cm – 762 cm) in large meeting rooms with regular lighting and 30 – 100 people in the audience
Above 2000: good for 12' – 25' (366 cm – 762 cm) screens and larger rooms with audiences of over 100 people, but can also be used in various room sizes with bright lighting
The contrast of an image has a significant impact on the picture quality as a whole. To assess a projector’s picture contrast, you will analyze the contrast ratio spec: the difference between the whitest whites and the blackest blacks projected by the device. High contrast is ideal, because it allows you to achieve deep blacks and subtle color variations.
The imaging chip will have a number of pixels measure top to bottom and side to side. Most high-resolution home theater projectors have 1080p-1920 x 1080 pixels. The higher the resolution of your projector is the smaller the pixels. You are ensured of viewing seamless images.
Ensure that your projector comes with a lens shift. It gives you a variety of options when it comes to placement of the projector. You can place your projector in a stationary position and shift the lens to the required location.
All of the factors listed above will affect the cost of the projector. You can also decide whether you wish to purchase a projector or simply rent one for a limited period of time.
Once you know how to choose a projector, remember that you still need to select a screen. Screens come in a variety of sizes and styles, including free-standing, wall-mounted, and retractable. Although you could project onto a wall, a screen will provide a more clear and consistent image. Plus, it will show off the projector’s top-notch performance.
