What is a projector?

Projector Parts labelled

Simply put, a projector is a device used to project media such as images and videos on to a surface, most commonly wall-mounted screens.

The projector comprises of several components as the image on the left suggests.

Projectors require an input source which is usually connected with a HDMI or a VGA cable. Input sources are normally the device that contains the content you want to display like a laptop or any computer.

Currently, there are a large variety of projectors available sold for private as well as commercial use.

This part of the page is here to help you understand the types of projectors available in the market that can cater to different needs and perhaps answer some of your questions.

Projector Lamps

The projection lamp is one of the most important components of a projector. The lamp also consists of a bulb.

Projectors require projector lamps to adequately project an image with the right brightness and these lamps do not last forever. They burn out and need to be changed in order for the projector to work the way it was made to.

Purchasing a projector lamp is a complicating procedure and is caused by the different brand names and the use of ‘glowy’ terms. Making it a difficult task to distinguish between Original Equipment Manufacturer (OEM) lamps and imitation lamps which would massively influence the performance of the projector.

Buying a projector lamp made by an imitation manufacturer can cause significant damage to your projector, void the projector warranty or leave you with a dimmed projection. Making that choice, more expensive in the long run. The best way to differentiate OEM lamps and imitation lamps would be the stamp located on the projector lamp globe. Most projector lamps will have the name of the manufacturer stamped on the projector lamp globe; whereas brand-less bulbs are usually imitation lamps.

On the other hand, it is also important that the right bulb be bought for the specific model and type of projector. Knowing your bulb type and wattage is essential for purchasing the right one.

Too complicated? With over 20 years of experience in the field, you can trust that we will provide and recommend only the best quality and service. Contact us to purchase a projector lamp & bulb so you don’t have to do the work.

Types of Projection

The first question you should ask yourself is how big is the room?

There are two types of projections that a projector could have. Short throw and long throw.

As illustrated, both types have different lengths of projection. The type of projection should be chosen based on the size of the room.

Short Throw Projectors – will be able to display a large image while being positioned quite close to the screen or wall you intend to project onto and. They can project from as close as 0.5m and as far as 3.5m, and is ideal for small spaces.

Long Throw Projectors – can project large images from up to 15m away from the screen or wall. Making it a suitable option for large spaces and parties.

Projector Types

Second question would be, “What kind of projector do I need and what will it be used for?”

The choices are fairly simple!

1) Office Projector

  • It is designed for office and educational environments, ideally made to assist in presentations
  • They often have various ports required to connect various inputs (Computers, laptops, etc)
  • Project clear and bright images in a variety of lighting conditions
  • Often used in professional situations
  • This is one that our customers generally look for!

2) Home Cinema Projector

  • Perfect for projecting large, clear and vibrant images
  • Often able to display Full HD
  • Designed to make set-ups more convenient, easy to connect to existing sound systems and TV boxes

3) All-In-One Projector

  • Possess integrated speakers, does not require any external speakers
  • Capable of projecting large, clear and vibrant images
  • Has short throw capabilities and high contrast ratios

4) Portable Projector

  • Small, lightweight and small, easy to carry around
  • Uses built in batteries


Another thing you want to decide on before purchasing is the resolution! What is resolution? In lay man terms, resolutions refers to the number of pixels an image is made of. In other words, the more pixels, the better the image quality.

So what are the different resolutions available for projectors?

  • Full HD – 1920 x 1080
  • HD Ready – 1280 x 720
  • WXGA – 1280 x 800
  • XGA 1024 x 768
  • SVGA – 800 x 600
  • WVGA – 800 x 480


As technical as lumens sound, it actually refers to the brightness of the image projected. The higher the number, the brighter the image!

So the question here would be “How bright do I want the image to be in the room?”

We recommend that a lumen of at least 3000 is used in any situation. In most cases where lights are involved, a lumen count of less than 3000 will not provide a visible image quality.

Although, it should also be very dependent on the application. Room sizes and audience size are very vital in making this decision.

We recommend:

Small classroom with lights – 3000 lumens at least and above

Big conference room with lights – 8,000 lumens to 12,000 lumens depending on room size

The projectors we carry have a minimum count of 3000 lumens!

In addition to the details above, it is also very important that you determine what you will be connecting the projector to and how.

Projectors can be connected to many different inputs with different cables and different types of ports.


  • the most common connection
  • any HDMI device (laptops, monitors, Blu-Ray Players etc.) will be able to connect to a projector with a HDMI port


  • receives digital video signals from computers
  • has small screws for secure attachment (allows manual tightening)


  • send analog image signals to a projector
  • connection has 15 pins and is on most laptops or computers
  • uses easy and secure screw-ons
VGA Port

Component Video

  • Used by most CD and DVD players
  • Uses 3 different coloured connectors (Green, blue, red)
  • transmits analog video signals
  • Provides better image quality than Composite Video Connectors
Component Video Port

Composite Video

  • Single yellow connector
  • Important if the intended source is an old video cameras
  • Lower quality images compared to what Component videos can offer but transmits analog video signals as well
Composite Video Port


  • only used by old computers
  • connection is sensitive to noise which make affect image quality
  • works the same way as composite and component video connectors
S-Video Port


  • it consists of a red and white cable connector
  • transmits the audio component of the video
  • assists the Composite and Component Video connections by providing the audio
RCA Port

3.5mm Input

  • commonly known as the aux input
  • sound quality is fairly similar to what an RCA connector can provide
3.5mm Input Port


  • send control signals from a computer to the projector
  • allows remote use
RS-232 Port


  • connects a computer via a UTP cable to an input
  • allows the user to control the projector remotely
  • can transmit video and sound with this input and provide mediocre quality
Network Port


  • Provides digital sound transmission
  • provides better sound quality than what the RCA and 3.5mm Input can provide
  • Common connection for laptops and most receivers
Optical Port

3.5mm Output

  • allows connections between projectors and external speakers
3.5mm Output Connection

12V trigger

  • suitable for projection screens with the same connection
  • the screen receives a signal as soon as you switch the projector on or off
12V trigger Port

USB (Universal Serial Bus)

  • can be backward compatible with VGA, DVI and HDMI
  • designed to work with most devices (laptops, computers, DVD players etc.)
Display Port

Display Technology

LCD, DLP and LED are the three major display technologies that are followed while manufacturing projectors.

LCD stands for Liquid Crystal Display and this ensures zero flickering. It also offers good colour reproduction.

DLP or Digital Light Processing ensures smooth video display and also offers vivid colours. Projectors, built following this technology are compact in size and these are quite strong against dust.

LED is a technology that is not used quite frequently while manufacturing a projector. However, handheld projectors are often designed using LEDs or lasers. LED projectors usually have very long life and these, too, ensure zero flickering.
