Choosing a projector model to suit your needs can be overwhelming; here are some key points to take into consideration as you make this important purchase.
Consider how far the screen will be from the projector, relative to the size of the screen. In some cases, it makes sense to select a projector with interchangeable zoom lenses (optional) for proper projector placement. Interchangeable lenses also affect image size from a particular throw distance. The size and shape of the meeting room will help you decide. Most manufacturers will state the image size range at specific “throw” distances to the wall, and that information is helpful as you plan.
Not all projectors are installed on a ceiling or wall. There are many users that place them on a cart to move them from room to room. Advances in technology have allowed manufacturers to design brighter projectors in a small cabinet size which makes this type of usage more favorable. For most customers, however, fixed mounting is much more preferable – for product security, less audible noise, and other logistical reasons.
In addition, ministry leaders change their entire approaches to presentations when projectors are always available to them in a fixed-mount configuration. They can access materials, the Web and apps, annotate using interactive projectors/whiteboards, and capture images for later use. The availability of affordable interactive technologies and apps are breathing new life into the ways that ministry leaders can share and highlight important information. For example, DisplayNote Software, used in conjunction with an interactive projector, lets instructors, students and others present and share content across any device creating the ultimate collaborative environment; multiple people can annotate at the board or from a device, while sharing and saving for all those in attendance.
These techniques create a much more dynamic environment, keeping those attending services, classes or special events much more engaged.
Image and Screen Size
In many small to medium sized rooms, image sizes will fall into the range of 60 inches to 90 inches. Medium to large sized rooms typically have screen sizes of 90 inches to 120 inches.
Generally, you can calculate optimal screen size by measuring the distance from the screen to the person furthest away. That should be a ratio of no more than 4:1 – for example, if the furthest seat is 32 feet away, you would select an 8-foot viewable screen.
Connecting Video/Data Sources
You may have video/data sources that you want to show on the projector such as DVD players, laptops, tablets and other smart devices. Common signal source connections can include composite video, s-video, component video, HDBaseT, DisplayPort, and HDMI with HDCP.
An established practice today is transferring data from a source to a projector using a network. Some sources, such as HD video, are best sent via a cable because the bandwidth on wireless connections isn’t usually fast enough for good video quality. But laptop images may work well via wireless and offer more ease-of-setup for the instructor.
