XGA vs WXGA Projector Resolutions

XGA vs WXGA Projector Resolutions

XGA vs WXGA Projector Resolutions. What’s the Difference?

Resolution is a crucial aspect of the projector selection process. You will either want a basic projector for general office/classroom powerpoint presentations, or you will want a top of the line HD projector for movie viewing or gaming in the comfort of your home.  The resolution you choose will depend on what you plan to use the projector for.

What is Projector Resolution?

Projector resolution is the effective number of pixels that a projector can render. Picture elements, also known as pixels, are the individual microscopic dots that make up the final projected image. The aspect ratio refers to the amount of horizontal and vertical pixels, which in turn reflects the sizes and dimensions of the projected image. XGA (Extended Graphics Array) and WXGA (Wide Extended Graphics Array) are the most commonly used by most projectors these days.

Extended Graphics Array

XGA has an aspect ratio of 4:3, this resolution offers an effective resolution of 1024 by 768 pixels, which equals to 786,000 pixels being rendered at any given time which results in an even sharper image and great detail. Usually, the higher the number of total pixels in any given resolution, the clearer the overall projected image will be.

 Wide Extended Graphics Array

WXGA carries a resolution of 1280 by 800 pixels, the WXGA resolution results in a much wider aspect ratio of 16:10, this means that the horizontal pixels make up twice the vertical pixels. The WXGA is the most commonly used resolution in many entry-level projectors these days, this is due to its clearer detailed images and very enticing price tag. The resolution for the WXGA equals 1,024,000 pixels.

Which Resolution is Right for Your Projector?

The number of resolutions a projector can display will also reflect on its price which is helpful when trying to decide which projector suits your needs.  Paying more for a higher resolution projector may pay off if you need to display higher-end graphics, but entry to mid-level projector will offer a cost advantage while being able to do the job you need it to do.

Each company will have different needs and different budgets, so it is important to point out that both projectors types are great, so the decision is up to you.

Are Lumens Important?

Are Lumens Important?

Are Lumens Important? The short answer is yes.

In fact, lumens are pretty important. Whether you need a projector for your home, office or school, there are many factors that should be considered before purchasing a projector; one of the main factors being lumens.

Projector lumens will always be listed in the projector specs, and to put things simply, the more lumens a projector produces, the brighter the image will be. It also means that the days of making a classroom or office pitch black before starting a projector are long gone, as the projector should be bright enough to project a perfect image in daylight.

What are Lumens?

Lumens are a way to measure brightness from light sources, so the more lumens a projector has, the brighter the light is. To help you better understand, below are some rough examples of lumens in other light sources:

  1. Candles – 13 lumens
  2. Average sunset – 400 lumens
  3. Car headlight – 1000 lumens
  4. 100 watt light bulb – 1600 lumens
  5. Projectors – these range from 500 lumens to 10,000 lumens

Do Lumens Matter?

As you can probably tell by now, lumens are one of the most important factors you need to consider before purchasing a projector. The brighter the projector is, the less dark or ambient light will matter with regards to picture quality. It also means you can place the projector as far away from the projector screen as desired.

Here is a rough guide of what can work when you have to choose a projector for different spaces.

  • To use a projector in a living room with the lights off, you would need approximately 1,500 lumens to 2,000 lumens.
  • To use a projector in an office or a small classroom with dimmed lights, you would need approximately 3,000 lumens.  If it’s in a hall or larger area, then a 5/6/7/8k lumens projector could be the best choice.
  • A movie theatre would need massive 20,000 lumens.

If you are unsure of what projector and lumens to choose for your space, it’s a good idea to get a specialist in projector installations to do a thorough site survey to assess the space, perhaps measure it out and to discuss what you need to achieve from your projector. A specialist will look at the full layout, stress test the walls and ceilings and advise on what the best mount, be it wall or ceiling, is best for space.

How Lumens Can Decrease Over Time

For projectors, the light source is within the bulb of the lamp. The bulb is of key importance to the amount of brightness a projector produces, and over time the brightness of the bulb will slowly decline and a replacement bulb can be bought to give the projector its lease of life back.

Light Me Up offers replacement bulbs for almost all projectors, and if you can’t find what you’re looking for, just ask! We are always expanding our range.

Long Throw VS Short Throw Projectors

Long Throw VS Short Throw Projectors

Long throw versus Short throw Projectors: Before we get into things, it is important to note what ‘short throw’ actually means. ‘Throw’ refers to the distance between the projector and the screen you are projecting the image to. So a short throw projector would not need to be too far away from the projector screen for you to have a clear and bright image. (more…)
