How to deal with the blurry projection image of the Xiaomi Smart Projector L1 Pro?

Several factors will affect the blurry projection image on the Xiaomi Smart Projector L1 Pro, such as hardware damage, software faults, and misoperation.
If the projector has a blurry projection image, please refer to the following details:
1. If all interfaces (including fonts, images, and software interfaces) have the problem of blurriness, please adjust the clarity of the picture through the auto-focusing function;
2. If a particular page is blurry, it might be a problem with the page UI. It is recommended to check other pages;
3. If the video playback results in a blurry picture, you can try switching the video resolution, or it might be due to the poor picture quality of the video itself;
4. If the interface becomes blurry after switching to the set-top box or an external HDMI device, please check the relevant settings of the set-top box or the external HDMI device (such as output resolution);
5. If the projection image is blurry when casting, that might be because the casting device's picture is not clear or has a low resolution.
If the above methods cannot solve the problem, please apply for the after-sales inspection.
