What to do if the projector picture is big

If the projector picture is large, it usually means that the projection distance is too close or the projector's focal length is set incorrectly. Here are a few possible solutions:

1. Adjust the projection distance: If the projector is too close to the screen, the picture may appear too large. You can try increasing the projection distance by moving the projector away from the screen. In general, the distance between the projector and the screen should be about 2-3 meters.

2. Adjusting the projection focus: Some projectors can be adjusted to change the screen size by adjusting the focus. You can try to adjust the focus of the projector down to make the screen smaller. The specific adjustment method may vary depending on the projector model, you can check the projector's manual for related information.

3. Adjust the screen resolution: If your projector supports multiple resolutions, you can try to turn down the resolution to make the screen smaller.

4. Check the projector settings: Some projectors may have an aspect ratio set by default, such as 16:9 or 16:10. If the aspect ratio of your projected content and the screen don't match, it may also result in an oversized picture. You can try adjusting the aspect ratio in the projector's settings to match the screen.

5. Replacing the screen or projector: If none of the above methods solve the problem, you may want to consider replacing the screen or projector. When choosing a new projection device, make sure its performance and size match your needs.

Hopefully these suggestions will help you solve the problem of a large projector screen.
