Pixel Map
The input signal is mapped to the LCD screen 1:1.
Pixel shape (resizer setting)
LCD panel pixels are square. To represent an image on an LCD panel, the original image needs to
be sampled with a certain spatial resolution. This results in a collection of values which are taken
from a ”point” in the image, and mapped to the LCD panel pixels. The square form of the LCD panel
pixel can introduce pixel shape artefacts in the image. A setting in the “resizer settings” OSD menu
is available to correct these type of artefacts.
Primaries
Primaries, or primary colors, are the basic and most pure colors (red, green and blue are commonly
used for display units) that are used to generate all the colors in a display gamut.
RGB or R’G’B’
The RGB notation is used when the signals are proportional to the tristimulus values X, Y and Z. The
R’G’B’ notation is used whenever we describe the gamma-corrected RGB components (using a
power function such as e.g. ITU.709).
