Firstly, you need to ensure that all projection equipment, including projectors, screens, cables, etc., are available. At the same time, you need to ensure that the projector's bulbs and filters are in good working condition. Additionally, you should test the brightness and color of the projector in advance to ensure it meets your needs. 2. Projection Environment Choosing an appropriate projection environment is crucial. Avoid using a projector in overly bright or dark environments as this may affect the projection effect. If the ambient light is too strong, you can consider pulling the curtains or using a screen shade. Meanwhile, ensure that there are no reflective objects between the projector and the screen, such as mirrors or glass. 3. Projection Settings Adjust the settings of the projector according to your needs. For example, you can adjust the projection size, color, and brightness. Depending on the content of your presentation, you may need to adjust these settings to achieve the best visual effect. Additionally, you can consider using the projector's built-in functions, such as image enlargement and rotation. 4. Operating Skills When operating the projector, pay attention to some details. Firstly, ensure that the projector is placed stably to avoid shaking. Secondly, regularly clean the lens and filter of the projector to maintain its good working condition. In addition, when replacing a bulb, make sure to operate it according to the manufacturer's instructions.
