Finding a projector for corporate use, one needs to consider 3 important aspects.
- Resolution.
- Brightness.
- Portability or weight.

The amount of data that can be displayed on screen is determined by the projector's resolution (amount of pixels that makes up the image). An important factor to first determine is the resolution of the PC or laptop that will be connected to the projector. For the best quality on screen one would want to match the projector with the resolution of the PC or laptop used. The current options on projectors are as follows: - XGA (1024x768) - XGA resolution models are the entry standard nowadays. Matching an XGA projector to your standard XGA resolution PC ensures you won't lose any detail.
- WXGA (1280x800) - WXGA resolution models matches most of the midrange widescreen laptops using standard 1280x800 resolution. They are becoming increasingly common.
- SXGA+ (1400x1050) - SXGA+ resolution is useful for detailed photography and data graphics and GIS applications.
- UXGA (1600x1200) - UXGA is for very high resolution workstation applications that are detail or information intensive.
You will get the best picture from a projector that has the same standard resolution as the laptop you intent to use. If you use a desktop Pc with a range of possible resolutions, choose the resolution most appropriate for the projector you are using. Remember that loss of sharpness will occur happens if you plug an WXGA laptop into a XGA resolution projector | | |
The brighter the projector, the higher the ANSI lumen rating
Things to Consider When Choosing Brightness
Size of the room:
This determines the size of the projected image that is required for easy viewing by everyone present. As size of the room increases, the image size must increase. This diminishes the perceived brightness of a projector as the light is spread over a larger area.
Light levels of the room:
A dark room will provide the best image regardless of projector brightness. However, most meetings require some lighting for note-taking and eye contact. A room where the lights cannot be turned off or dimmed or where windows cannot be blocked will require a bright projector. The same projector placed in a perfectly dark room will likely be so bright that it will give your audience a headache, so this is a critical factor.
Application
Applications such as training and workgroups will demand more brightness, because these applications also require more room light for note-taking and communication. Applications that use presentation graphics, photographs, or video are more likely to be shown in a darkened room, and therefore do not require as much light output. If the projector will serve multiple locations (either within a building or because of traveling), consider your most demanding setting.
Projectors can be grouped by ANSI lumen output as follows:
Less than 2000 lumens. Typically small and highly portable, these are the lowest light output projectors available today, and they are typically the least expensive. For display of training videos or still photography in a darkened room, projectors in this category may be perfect for your needs. Keep in mind that the low light output means that you will want to make your presentations in a dark or dimly lit room so that the image on the screen is not washed out by ambient room light.
2000 to 3000 lumens. These machines are suitable for normal business conference room and classroom use. Presentations should be done with the room lighting reduced somewhat for best screen viewing. A completely dark room is usually not necessary.
3000 to 4500 lumens. This represents the high-performance range of the portable and semi-portable projectors. Products in this class are suitable for large conference rooms and classrooms. They offer more flexibility in terms of ambient room light, since the image is bright enough that a reasonable amount of room light can be tolerated without washing out the image. They also offer more flexibility in terms of audience size, since they produce enough lumens to properly light a larger screen.
4500 lumens and up. These ultra-bright projectors are in several performance classes unto themselves, ranging from 4500 lumens up to 12000 lumens or more. Prices of these products also cover a wide range depending on other performance characteristics. They are used in a variety of large venue applications, including board rooms, conference rooms, training rooms, auditoriums, churches, concerts, nightclubs, and so forth. | | |
If you travel a lot, you probably want a light small sized projector that still fits your resolution and brightness needs. Projectors in this class usually weigh between 1 and 2 kg.
If you travel occasionally, but want a bit more performance and are willing to carry a heavier unit that are still very portable but brighter than the micro light projectors. Projectors in this class usually weigh between 2 and 3 kg.
If you don't intend to travel with the projector, but still want the ability to move it around the office, from classroom to classroom, a projector that weighs between 3 and 4 kg. Projectors in this class usually feature better brightness and multiple connection options.
Projectors above the 4 kg weight bracket are usually very bright and feature rich and are most likely intended for permanent installations such as larger boardrooms and auditoriums. | | |
