Box_50mm and Box_64mm
Description
The primary version has a solid white box in the
center of the active video. Depending on the image
selected, the box is either 50 millimeters (1.97
inches) or 64 millimeters (2.52 inches) square. If
there’s room, information on the current format
appears below and to the left of the box. This shows
the number of active pixels and lines as well as
the horizontal and vertical scan rates. An I after
the number of active lines indicates the format is
interlaced. The secondary version draws a black
box and black text on a white background.
Note – The box will be the correct size only if the correct
physical active video size is set in the format.
Test
Brightness control adjustment
Purpose
The wrong brightness setting may cause other tests
such as Contrast, Focus and Beam Size to be invalid.
An accurate brightness setting helps give repeatable
measurements throughout other tests.
Method
Center your light meter probe within the center
square and adjust the monitor’s brightness control
to obtain the required light meter reading.
