A business projector is the best way to get your point across to a large number of people. Whether it is in a small training room, large conference hall, intimate sales meeting or even a one on one presentation the big screen presentation can be essential to education, training, or sales.
When selecting a projector for business presentations the main points to consider are:
In a business set up selecting the brightness is one of the most important factors. In essence the more brightness you have the larger the screen size can be, and the more light can be in the room.
If you have a projector without enough brightness (measured in lumens) you can still use it but we would recommend to limit the screen size if the room is bright or try to dim the room by closing curtains or turning lights down.
A bit of a guide on brightness:
3000-4000 Lumens for sizes 82” to120” in rooms with normal artificial lighting.
4000-5000 lumens for a bright room image size of 120” to 140”
5500+ Lumens when you are after a large 120” + image in a bright room.
Selecting the correct resolution is the next step, of course the higher the resolution the better but this will push up the cost of a projector. The native resolution of a projector is literally the count of the pixels (the little dots) that make up the image. For example Full HD is 1920x1080 (also known as WUXGA) so if you got up close to the picture and had a lot of time on your hands it would be 1920 pixels wide and 1080 pixels high.
Below is a list of resolutions and a bit of a guide to what sort of presentations they can be used for:
800x600 SVGA – Basic PowerPoint and presentations with big bold text
1024x768 XGA – More detailed PowerPoint and documents
1280x800 WXGA (HD) – Video, images and smaller text or detailed presentations
1920x1080 WUXGA (Full HD) – Fine lines, spread sheets, Full HD video and high detail presentations.
3840x2160 (UHD) – CAD drawings, large image presentations, UHD video.
The size of the projector is the next factor. Generally the brighter and more feature rich the projector is the larger it will be. Of course, if it is being installed then size and weight are not much of a concern but if you are moving it around from one office to another or doing daily sales calls you would want the projector to be as small as possible.
For a reasonably portable projector you would aim to have it weigh under three kilograms. If you are looking to travel with a projector all day long carting it from office to office you can still get a reasonably bright projector under 2kg. For something super portable you can look into the Pico sized LED projectors. These will weigh much less even under a kilogram but the super small projectors will sacrifice brightness to get to a small size.
Throw distance is how far the projector will be from the screen or wall to achieve a certain image size. Most projectors will require a few metres to get a decent image size and in many cases this will work quite well. In some situation where there is a small meeting room or a setup where you would like a presenter to be in front of the image a short throw (or short distance) projector can be beneficial. A short throw projector will costs a little more but depending on the setup it is good to consider the projectors throw distance to make sure it is suitable.
