Are you looking for a projector for your large classroom, training room, or auditorium? Then what are the most important features a projector should have?
High Brightness
Generally, large classrooms are well lit by daylight, such as window light or indoor lighting. High brightness ensures projection clarity.
The basic requirement for brightness is over 4000 ANSI lumens. In strong ambient light environments, it may need to exceed 5000 ANSI lumens.
High Resolution
Usually, FHD resolution (1920×1080) is recommended for educational projection to ensure that text, charts, and videos are displayed clearly—especially complex courseware or high-definition teaching resources.
It also needs to be compatible with widescreen display formats (e.g., 16:9 or 16:10) and multimedia content.
Stability and Durability
Heat dissipation and dust-proof design:
A fully sealed optical engine helps prevent malfunctions caused by dust intrusion. A high-efficiency heat dissipation system supports long-term continuous operation.
Light source lifespan:
Laser light sources generally offer a longer lifespan and slower decay compared with traditional bulbs. Ideally, the light source should last over 20,000 hours in Eco-mode.
Flexible Installation and Keystone Correction
A 360° installation option allows adaptation for ceiling mounting, rear projection, and more.
Horizontal/vertical keystone, 4-corner, and arc adjustment features help in lecture halls or with irregularly shaped walls.
Interface Compatibility and Expandability
Essential I/O ports: HDMI, VGA, USB, AV Out, ensuring compatibility with PCs, tablets, and more.
