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.
