Vertical Scan Rate
The rate at which the frames of the incoming signal are refreshed. The rate is set by the vertical synchronization from the source and
measured in Hertz.
Vignetting
Optical cropping of the image caused by the components in the projection lens. This can happen if too much offset is applied when
positioning the image using the lens mount.
Vista
An aspect ratio of 1.66:1.
WUXGA
A display resolution of 1920 x 1200 pixels with a 16:10 screen aspect ratio. (Stands for Widescreen Ultra Extended Graphics Array.)
Y

YUV
See Pr, Pb.
ZScreen
A special kind of light modulator which polarizes the projected image for 3D viewing. It normally requires that images are projected onto a
silver screen. The ZScreen is placed between the projector lens and screen. It changes the polarization of the projected light and switches
between left- and right-handed circularly polarized light at the eld rate.
