Projector Specifications: All You Need to Know in One Guide

Choosing a projector can be overwhelming, but it does not have to be. There are so many different projectors to select from, and they all have other specs that can make your head spin. Here is a guide with all the information you need to select the right projector for your home cinema or business meeting needs.

Types of Projection System or Technology

There are four different main types of projectors that you can use.

DLP or Digital Light Processing

DLP projectors are usually the light produced inside the machine’s light source that goes through a focus lens. It then passes through a spinning colour wheel that separates colour from colour and is projected onto a Digital Micromirror Device or DMD chip. Each microscopic mirror attached to the DMD chip adjusts the angle established from the digitised video signal stored in the chip’s memory. It is so the light that is reflected produces the image that is projected. DLP projectors have more accuracy in terms of colour, and they don’t quickly fade.

LCD or Liquid-Crystal Display

On the other hand, LCD projectors utilise LCD panels to modify the colours based on the video signal. It then generates the image that is projected onto the screen. Using LCD projectors’ colours are vivid and more saturated. They usually have weaker contrast levels, and the colours produced tend to fade in the long run.

Liquid-Crystal on Silicon (LCoS)

LCoS projectors project images by reflecting light off of three individual panels. They usually have the highest contrast ratios and are perfect for dark rooms or locations. Although, images can appear blurry during fast-paced scenes. They are not designed for portability as well. 

Light Emitting Diode (LED)

LED is the most common technology in projectos. This kind of projector uses a series of LED lights to project images. They produce better colours than LCD models and consume less power than every other type of projector. However, they are not as bright as DLP or LCD models - so if you need a brighter projector, one of those might be better for you.

Light Source

Projectors need light to project images. There are two types of light sources, laser and lamps.

Laser

The laser light source is a game-changer. It has many benefits, including high brightness and longevity that will lower your repair or maintenance costs in the long run. With this type, you can turn it on quickly for short periods between uses without worrying about lamp depreciation. Plus, colour preservation means no more fading colours over time either, so enjoy them now while they last with their initial cost much higher upfront but worth every penny when considering all these advantages alone!

Lamp

Projectors with lamp light sources usually are less expensive but have strong colour performance. If your projector has a mercury lamp, it might have a short lifetime. During the lifespan, the projector’s image will gradually become darker and more yellow. The saturation and contrast levels will most likely deteriorate. With this, you will require maintenance from time to time which can become expensive in the long run.

Brightness

Lumens is the specification for brightness for projectors. These are the total light output produced by the projector’s light source over the given amount of time. The average light in a room is usually 250 lux (lumen per square meter). With that, you need a projector with a lumen with about five times the average light so that your audience can still see the projected image.

Image Quality

The image quality is tested with three different aspects as Contrast ratio, aspect ratio, and resolution.

Contrast Ratio

The contrast ratio is the brightness of light reflected from a solid white image to a solid black image. It means that if the specification of contrast ratio of your projector is 5000:1, the solid appearance of the picture will be 5000 times brighter than a black image. Note that if the contrast ratio is high, the more detailed and sharp the portrait can be. The contrast ratio on your projector is what makes it possible for you to notice the subtleties in colour and shadow that were never as clear before. This quality will allow anyone who watches movies with low contrasts ratios to take full advantage of their favourite films, even though they might be difficult at first glance.

Aspect Ratio

The ratio in the middle of the width and height in projected images refers to the aspect ratio. Usually, traditional TVs have an aspect ratio of 4:3, which is almost a square, but with modern technology, they can transmit up to 16:9 as well, just like in projectors. A projector’s aspect ratio can go from 4:3 (XGA), 16:9 (FHD/4K), to 16:10 (WXGA/WUXGA).

Resolution

The resolution of a display device refers to the number of horizontal and vertical pixels it has. The larger these numbers, the clearer an image will appear on the screen; so here are some common resolutions:

  • XGA: 1024x768
  • WXGA: 1280x800
  • WUXGA: 1920x1200
  • FHD: 1920x1080
  • 4K: 3840x2160

Projection Distance

Projection distance is technically the distance between your projector and projector screen or wall. If the projection distance is short, the number of lenses should be high. It should have higher complexity of projector design and has a lower yield. If you look for a projector with a short projection distance, that is usually more expensive. 

Throw Ratio

The throw ratio is the projector’s distance from the screen, divided by the screen's width. It sounds complex, but it is easy to understand. Have you ever used a projector and wondered why an image was small near a screen and big when it was farther away? The reason for this is because of the throw ratio. If you have a fixed width for your screen, a shorter distance means a lower throw ratio.

Zoom Ratio

If the projector you have has a built-in zoom lens, you can adjust the size of its projected image from a fixed position without moving the projector near or far from the projector screen. The zoom ratio is between the width/length of the largest and smallest image the lens can produce from a given position. Having a built-in zoom for projectors gives you more flexibility in terms of your installation options. 

Lens Shift

Lens shift lets you centralise the image. Sometimes, the projected image can go beyond the projector screen, which can be annoying. A lens shift allows the projector’s lens to vertical shift and move the image up or down, while its horizontal shift lets the lens move the image left and right. You don’t have to manually put your projector in the middle of the room to ensure that the projected image will be at the centre of the projector screen.
