A projector purchase order that looks fine on paper can still disappoint in a bright classroom or a long, narrow coaching institute hall. Before you finalise a model, it helps to check five things beyond the headline price.
1. Brightness (lumens) for your room
A room with large windows and daytime use needs at least 3,500–4,000 ANSI lumens to stay readable without blackout curtains. Smaller, darker rooms can work well with less.
2. Throw distance and screen size
Short-throw projectors sit close to the screen and work well in compact rooms; standard-throw units need more distance behind the screen. Always confirm the throw ratio against your actual room length, not just the projector's maximum screen size.
3. Resolution
Full HD is the practical minimum for text-heavy lessons; 4K input support future-proofs the room as more content moves to higher resolution.
4. Connectivity
Check for HDMI, USB and wireless casting so teachers can connect a laptop, tablet or phone without extra adapters.
5. Installation and after-sales support
A projector is only as good as its mount, wiring and the technician who calibrates it. Ask your supplier what installation and warranty support is actually included — not just the hardware price.
DigiCast handles all five of these as part of a single quote, from room assessment to final calibration. Talk to our team about your room dimensions and we'll recommend the right model.
