Upsizing your image with a projector
Projectors have progressed well beyond slide carousels, “transparencies” and movie reels. In fact, modern HD projectors are packed so full of technology (with relatively low set-up costs) that they are well worth serious consideration when designing your boardroom. Here are some basics to give you an idea of what to expect.
16:9: This is a wide screen format, much like the flat screen TV’s that we discussed in Part 2 (The low-down on high-tech TV’s) and is associated with HD resolutions.
4:3: This is the old square CRT (cathode ray tube) TV shape, associated with the older, standard definition TV’s.
The throw distance is the distance between the projector and the projector screen. If the size of your room requires that you have a 3m projector screen, you would need to mount your projector further back, which in turn means loss of intensity and brightness. Accordingly, you would require a brighter projector, which adds cost.
Projector brightness is measured in ANSI lumens. You will often see it as part of the projector description, e.g. Panasonic Data/Video Projector 3000ANSI lumens. The higher the ANSI lumens, the higher the cost. But there are also two other factors that affect image brightness:
- Room brightness – well-lit rooms will require brighter projectors
- The projection screen – screens that have a high gain, reflect more light and are therefore brighter. Again, these are higher in price.
Just like cameras, some projectors will have better lenses – with a better focal range and zoom than others. It’s all about image quality – and the better the lens type and zoom range, the pricier the projector is bound to be.
There are various types and screen sizes to choose from:
As the name suggests, this screen is permanently mounted against your wall.
These are similar to what many of us had at school – retractable, and out of the way when not in use. These are the most cost-effective options.
These are normally concealed within the ceiling void and are controlled via a switch on the wall, a remote control or a centralised control system. Because they are mounted within the ceiling, they usually also require a ceiling mount box, adding to the cost.
