How do you choose a data projector? How much money you should spend? How much lumens do you require?
First of all, there are two type of business projector 1) Portable Projectors- the ones that you carry around for meetings or presentation. 2) Projectors that usually stay in the same room. (Installation projector)
How portable do you need depend on how much weight you can carry. Some people prefer a palm sized type projector, some can carry up to 2kg. The smaller the projector it is, the lesser the brightness it has.
There are some palm-sized Pico projectors that are weigh under 500 gram and can produce 700 or 800 lumens. They are suitable for room for small meeting with 10 people or so. E.g Optoma ML 750, Optoma ML750st
How big and heavy you can carry, all depend on your personal preference.
Some projectors have a USB Media player built in. They do not require a PC to play media file. Common files that can be play are: Mpeg, Jpeg, Microsoft Word, Excel and Powerpoint. It is ideal if you do not wish to carry a laptop around. e.g Optoma Eh460st, Optoma Eh465
If you room’s setup is too hard to fit in a long video cable or you like the freedom of not having to connect to a cable and be able to walk around boardroom while presenting, consider wireless projector! Wireless projector allows you to show documents, picture or movies or documents from your PC or MAC desktop or handheld device to the screen. Some wireless projectors include wireless adapter, some require adapter to be purchased separately. Please refer to our wireless guide:
Native Resolution: Refer to the number of pixels that can be shown natively from the projector.
SVGA - 800x 600 pixels (Half a million pixels) Less expensive projector for basic presentation. If you're on a tight budget and only need to show simple graph, charts, or video, this is the one for you. Or if you only use the projector few times a year and want the cheapest option.
XGA - A bit better than SVGA, 1024 x 768 pixels (780k pixels) give you clearer picture. Suitable for old PC or laptop that display in 4:3 aspect ratio.
WXGA - High Definition (HD) quality but in wide screen format 16:10 aspect ratio.
FULL HD- The best resolution for projector on the market at the moment. If you need to show a lot of detail e.g Digital Photography, Engineering Drawing, Scientific Data Excel Spreadsheet with lots of row and cells, this is the right one for you. This is also the standard resolution for home theatre projector nowadays.
WUXGA - Same as FULL HD but in 16:10 ratio Wide Screen format. The picture looks taller than FULL HD.
Contrast is the measure of darkness, from the whitest white to the darkest black colour.
For basic presentation with Svga projector should be enough.
For business presentation for presentation that have a lot of details, a Full HD projector is recommended.
If the native resolution of the video input is more than the native pixels of the projector, the projector will display at the maximum resolution that it can support. When the video has less resolution than the projector, the projector will display accordingly to the video signal to the video’s native resolution.
If you’re using your projector for presentation, contrast ratio is not as an important factor than lumens.
There are factors determine how bright a projector do you need. Dark room usually give the best picture
Some rooms require notetaking and eye contact, thus room's light need to be left turned on.
A room where light cannot be turn off or dimmed or where there is no curtain or blind to block off the windows will require a brighter projector.
1000 - 1400 lumens brighter Ultra Portable projectors, most are led, WXGA, some come with Full Hd native resolution.
2500 - 3500 lumens - most DLP LCD projectors come in these range of standard lumens
4000 - 5000 lumens - Suitable for 100 people or so. Optoma Eh512
6000 - 7000 For large room such as conference room. Suitable for 150+ people or so. E.g Optoma W515T
