All projection side projections will have this phenomenon. Because the position and shape of the projection light source itself are fixed, the shape and size of the projection screen are adjusted through zoom and keystone correction, and the original light source position remains unchanged.
Automatic keystone correction is affected by different use environment factors, and the effect may be poor. In this case, manual adjustment can be used to ensure the effect. Specific steps: [Settings]-[Keystone correction]-[Manual keystone correction]
The projector is a spherical lens, it is impossible to achieve the absolute same refractive index in all places, so after focusing, it can only ensure that most of the picture is clear. This is also the case with other projectors on the market.
The thermal defocus phenomenon during the use of all smart projectors, you can manually adjust the focus after it is out of focus, and it will not lose focus again after it is stabilized. (Ensure that there is no obstruction at the cooling air outlet of the device when in use.)
