Specific questions about projectors
Why is my picture blurred despite using AUTO FOCUS?
Projectors with AUTO FOCUS (LT25, LT30, LT35, NP10, NP50 and NP60) always focus automatically.
However, if a digital image setting has been activated in your projector the image will always be displayed in interpolated fashion, which means you get a blurred image despite using Auto Focus.
To avoid this, deactivate all digital settings in your projector which could lead to an interpolated image. The following points should be noted concerning these digital settings:
a) If your computer runs at a higher resolution than the natural resolution of the projector then interpolation will take place. For instance, an SVGA projector requires an 800x600 computer signal, so any higher resolution such as 1024x768 will be interpolated to 800x600.
b) Ensure that you have an optimum set-up for the projection screen which does not cause any trapezoidal or keystone distortion which could render automatic or manual keystone correction (including 3D reform) necessary, as any such digital keystone correction would then interpolate your image.
