PROFESSIONAL PROJECTOR INSTALLER

Choosing your first projector can be daunting. Here's a simplified guide to help you understand what different features mean and whether it is suitable for your needs.

​

1. LCD or DLP?

The terminology LCD refers to a technology whereby 3 colour panels red, blue and green are assembled to project and reflect light to produce an image. DLP meanwhile utilises a DMD chip together with a colourwheel and reflective mirror or glass to project light and produce an image. Typically DLP projectors are cheaper and easier to maintain, however viewers often claim LCD projectors produce a much more vivid and sharper image.

​

2. Laser or Lamp or LED?

Traditional projectors are all lamp based (light source comes from a lamp or bulb). Laser projectors differ whereby the image light source is a laser beam. Laser projectors typically outlast lamp based projectors twice as long, however the cost to replace the laser diode can be prohibitive.  LED light source is found commonly in small portable projectors and are not widely found in the market.

​

3. Lumens or Brightness

Lumens or ANSI Lumens is a measure of the total quantity of visible light emitted by a source per unit of time. The higher the value, the more brighter the brighter the image is. The projector lumens requirement can depend on many factors including the room size, lighting position, projector position and many more. 

​

4. Resolution

Resolution refers to the number of pixels per image. For projectors the most common resolutions are XGA (1024 x 768), WXGA (1280 x 800), WUXGA (1920 x 1200), Full HD (1920 x 1080) and 4K (4096 x 2160). The higher the resolution, the sharper the projected image would be. For most corporate and education projectors, XGA, WXGA and WUXGA projectors are used. Meanwhile home theatre projectors have resolutions of Full HD or 4K.

​

5. Brand

We always recommend customers to choose a brand with a comprehensive warranty coverage and a minimum of 2 years warranty. In our experience, projectors break down for many reason including lack of use. Therefore it is important to buy from an authorised reputable seller with after sales service.

​

6. Wireless connectivity

Most projectors have built-in wireless capability or at least the option to add on wireless connectivity via an additional usb dongle. If wireless connectivity is a priority, it is best to purchase the additional wireless accessory from the brand itself. Otherwise there are many third party casting hardware that can be easily purchase, however do not that the image quality will not be equivalent to the quality when using a cable.
