Brightness: Projectors are rated in lumens, which indicates their brightness. Higher lumens are ideal for well-lit environments or larger screens, while lower lumens may suffice for darker rooms or smaller screens.
Resolution: Projector resolution determines the clarity and sharpness of the projected image. Common resolutions include HD (720p), Full HD (1080p), and 4K Ultra HD. Higher resolution projectors offer more detailed images.
Projection Technology: There are different types of projection technologies, including DLP (Digital Light Processing), LCD (Liquid Crystal Display), and LCoS (Liquid Crystal on Silicon). Each technology has its advantages and disadvantages in terms of image quality, color accuracy, and cost.
Throw Ratio: The throw ratio determines the distance between the projector and the screen required to achieve a certain image size. Short-throw projectors are ideal for small spaces, while long-throw projectors are suitable for larger venues.
Portability: Consider the portability of the projector if you need to move it between different locations frequently. Portable projectors are lightweight and compact, making them easy to transport.
