The brightness or contrast on the Mi Smart Projector can’t be adjusted.
Troubleshooting if the brightness or contrast on the Mi Smart Projector can’t be adjusted, please refer to the following steps:
1. Make sure the brightness and contrast adjustments aren't locked in the projector's settings menu. Sometimes, they're restricted for certain modes or inputs;
2. Check if the remote control batteries are working well and sending signals properly. Weak or faulty batteries might stop the remote from adjusting settings;
3. If you're using the projector's physical buttons, ensure they're not stuck or broken. Clean them and check for any damage;
4. Ensure the projector isn't in a preset mode like "Dynamic" or "Standard" that overrides manual adjustments. Switch to a user-defined mode or adjust settings within the current mode;
5. Look for any firmware updates for your projector. Updates can sometimes fix issues with adjusting brightness and contrast. Update the firmware if available;
6. If you're using an external device, check if its resolution and settings match the projector's requirements. Some devices might override the projector's settings;
7. If the problem persists, try resetting the projector to its factory settings. Keep in mind that this will erase all settings and data, so back up any important information first;
8. If the issue persists, contact your local after-sales for further assistance regarding this issue.
