What to check if 3D Auto Keystone and Real-time Focus do not work
If 3D Auto Keystone or Real-time Focus is not working as expected, check the following items.
Case 1. If the protective lens film is still attached, keystone correction and focus may not work properly.
Remove the film before using these features. If necessary, gently wipe the lens with a soft cloth. The lens is sensitive to dust, so handle it with care.
Case 2. Dust, debris, or foreign materials on the sensors at the top of the product can affect operation.
Use a cotton swab to carefully clean the sensors.
Cautions:
- Make sure the Samsung logo is facing down when placing the product.
- Do not project the light onto another light source or an obstacle.
- These features may be affected by external light, the distance between the projector and the wall, and the projection surface.
If the screen correction result is not satisfactory, adjust individual features in AI OptiScreen Custom mode on The Freestyle+. If the issue continues, we recommend updating your Freestyle+ to the latest software and, if needed, contacting Samsung Support for further assistance.
Note:
- Screenshots and menu paths may vary depending on the model and software version.
- Supported features may vary depending on the region.
