Edge tear
An artifact observed in interlaced video where the screen appears to be split horizontally. Edge tears appear when the video feed is out of
sync with the refresh rate of the display device.
EDID(ExtendedDisplayIdenticationData)
Information stored in the projector that can be read by the source.
EDID is used on the HDMI, DVI and VGA inputs, allowing the source to automatically congure to the optimum display settings.
EDTV(EnhancedDenitionTelevision)
A progressive digital television system with a lower resolution than HDTV.
Field
In interlaced video, a part of the image frame that is scanned separately. A eld is a collection of either all the odd lines or all the even lines
within the frame.
Frame
One of the many still images displayed in a sequence to create a moving picture. A frame is made of horizontal lines of pixels. For example,
a 1920x1080 frame consists of 1080 lines, each containing 1920 pixels. In analog video frames are scanned one at a time (progressive
scanning) or split into fields for each eld to be scanned separately (interlaced video).
Frame rate
The number of frames shown per second (fps). In TV and video, a frame rate is the rate at which the display device scans the screen to
“draw” the frame.
Frame rate multiplication
To stop low frame rate 3D images from ickering, frame rate multiplication can be used, which increases the displayed frame rate by two or
three times.
