1. Brightness: Brightness is an important indicator of projector performance, which determines the performance of the projector in a well-lighted environment. A high-brightness projector can project clear and bright images in a bright environment. 2. Resolution: Resolution refers to the clarity of the image projected by the projector. A high-resolution projector can project a more delicate and clearer image. 3. Contrast ratio: The contrast ratio refers to the black and white contrast effect of the projected image. A projector with a high contrast ratio can show a richer sense of hierarchy in the picture. 4. Projection size: Projection size refers to the size of the image that can be projected by the projector. Choose the appropriate projection size according to actual needs. 5. Stability and durability: An excellent projector should have excellent stability and durability to ensure long-term use and good maintenance. 综上所述，一款优秀的投影机不仅需要具备强大的功能，还需要在性能方面表现出色。只有功能与性能的完美结合，才能满足用户在不同场合的需求，提供更好的视听体验。
