Things to consider

When you purchase a projector from Universal AV you can be reassured we will address the following factors on your behalf. Nevertheless, when buying your projector the following considerations need to be made:


1 Resolution

This is a very important consideration which mainly depends on the desired screen size you wish to project onto and the size of the room/audience. Resolution can affect the shape, size and quality of the image. For example, if you have a standard resolution projector, such as a XGA, the quality of the image may be superb in a small boardroom setting. However, as soon as you use that same projector in a larger room, such as a large training hall, you will notice pixilation and distorted quality.

The following are typical projector resolutions:

  • XGA: This consists of 1024 x 768 pixels forming a 4:3 square ratio image. Suitable for typical desktop PC’s, Mac’s or analogue video equipment such as DVD players. This resolution is suited for smaller room sizes for PowerPoint presentations and small meetings. XGA projectors are typically inexpensive.
  • WXGA: This consists of 1280 x 800 pixels forming a 15:10 widescreen ratio. Suitable for modern laptops with a widescreen display, traditional desktop PC’s, Mac’s and analogue video sources such as DVD players. High Definition input, such as from a Blu-Ray player, are possible though higher resolutions are recommended for ultra-quality. Like XGA projectors, WXGA are fairly inexpensive offering budget value.
  • SXGA+: This consists of 1400 x 1050 pixels forming a 4:3 box ratio image. Suitable for desktop PC’s, Mac’s or analogue video equipment. The slightly higher resolution allows for greater quality which benefits displaying applications such as Excel where higher detail is required. These projectors are slightly more expensive, but still offer great value for money.
  • HD: This is 1920 x 1080 pixels, the standard high definition resolution, forming a 16:9 ratio image. Suitable for higher quality applications such as HD inputs like Blu-ray players and slideshow presentations to larger audiences in larger rooms.
  • WUXGA: This is 1920 x 1200 pixels forming a 16:10 widescreen ratio. These projectors are suitable for High Definition PC’s, Mac’s, laptops and video equipment such as DVD / Blu-Ray players where that extra quality is needed. The larger resolution also makes these projectors more suitable in bigger rooms in order to avoid pixelated images.
  • 4K: The latest and greatest resolution available forming 3840 x 2160 pixels in a 16:9 widescreen radio. Undoubtable projectors with these resolutions provide the highest resolution at present which is suitable for any size room (providing the highest, sharpest quality in smaller rooms). Suitable for all uses (including HD and 4K inputs) and for larger rooms. These projectors will be more expensive, but are certainly worth it if you want to engage your audience and provide high-quality presentations or entertainment.


2 Brightness

Projector brightness is measured using lumens, which is a representation of the luminosity and brightness the project generates. The rule of thumb typically is that brighter projectors are better, however so is the price. We will consider your budget and requirements to choose a projector that gives the brightness best suited for your room and that meets your budget.


3 Light Engine

These are the different technologies behind the scenes that actually generates the emitted image. The general rule of thumb here is that the newest technologies will generally give a more vibrant and bright image with a higher contrast ratio, however they will usually cost the most. Therefore if quality and efficiency is your desire we recommend using the newer technologies.

  • LCD: Liquid Crystal Displays. Offering vibrant images and value for money. Perfect for presentations, analogue & digital inputs & PC / Mac outputs.
  • DLP: Digital Light Processing. Offering great contrast ratio, brightness and vibrancy. Perfect for high quality requirements such as projecting Blu-Ray content or for big events, halls and theatres.
  • LED: Light Emitting Diode. This is a relatively new and trending technology offering greater contrast, brightness and vibrancy than traditional LCD projectors. Perfect for all aspects of audio visual presentations especially if long-life is a requirement for the projector as these typically have the longest life.
