DVDO AVLab TPG - 4K Test Pattern Generator

k. Grayscale multipoint and gamma: If available use 10 point gamma and white balance controls
to perform final adjustments across the entire luminance range. Again, leave green with zero
error.
l. Color Management System:
i. Goal is to get every parameter correct for every color. CMS controls, not present on
every display (and if not a DVDO Duo adds that capability to any display) normally
provide saturation, hue, and luminance for each specific color to properly position that
color on the reference color chart. For primary colors (R, G, B), start with luminance,
then adjust the color with saturation and hue (or x, y) and then readjust luminance. For
secondary colors (C, M, Y), focus primarily on hue and saturation.
m. Recheck everything – since many of the controls are interactive, the goal is to find the best
balance between all the settings. You should be able to go through the entire workflow without
making any further changes. Once this is done, a post-calibration report should be run to
provide to the end customer.
4) Double check the source and any other components in between like the AVR or a video processor
a. Need to understand the best place to: up-convert to 4K, convert to RGB, may need to set
brightness or contrast here. Oppo is a good example where you use a test pattern generator –
adjust the TV correctly, then come back and adjust the source as necessary to make it all
match.
