<strong>Veritas</strong> <strong>et</strong> <strong>Visus</strong> <strong>Display</strong> <strong>Standard</strong> February 2009<br />
The chromaticity diagram for the Sharp unit indicates that the red, green and blue primaries are more saturated than<br />
the HDTV Rec.709 standard. These saturation values can be reduced and brought into b<strong>et</strong>ter agreement with the<br />
Rec.709 standard by using the user color saturation control. However, when this is attempted the picture quality and<br />
accuracy degrades substantially due to the unit’s internal automatic dynamic signal processing, which cannot be<br />
disabled through the user menus and controls. The control s<strong>et</strong>tings used for the Sharp unit for this figure and all<br />
other figures, tables and viewing tests were carefully chosen to produce the best and most accurate picture quality<br />
match with all of the other HDTV units being tested.<br />
The chromaticity diagram for the LG hospitality unit indicates that it is significantly deficient in red, which was<br />
obvious in the viewing tests.<br />
