Data projectors are fantastic presentation tools for screen sizes larger than 1.5m. Here’s how to choose the best data projector for your school hall:
- Resolution: Determine the desired resolution based on the content you will project. XGA (1024 x 768) and WXGA (1280 x 800) are the standard resolutions. Full HD (1920 x 1080) and 4K Ultra HD (3840 x 2160) are higher resolutions that provide sharper and more detailed images, especially when displaying text.
- Brightness: Consider the brightness (measured in lumens) required for your intended usage environment. Brightness requirements vary depending on ambient light levels, screen size, and distance between the projector and the screen.
- Throw ratio and projection distance: The throw ratio indicates the distance between the projector and the screen relative to the image size. It helps determine the appropriate projector placement.
- Connectivity: Does the projector offer the necessary connectivity options to connect with your input sources, such as laptops, Blu-ray players, or streaming devices? The most common connectivity options include HDMI, VGA, USB, and wireless sharing.
- Portability and installation: Portable projectors are lightweight and easy to transport, while fixed installation projectors are suitable for dedicated spaces. Consider factors like mounting options and the availability of carrying cases for transportation.
- Brands: Epson, Sony, Viewsonic, Vivitek, and Panasonic are the biggest names in the data projector market. All these brands offer excellent products.
