Manual of AVSHD 709 Disc Calibration Patterns - BASIC SETTINGS-1
Black-Level – Most often this control will be called brightness, and you can use chapters 1 and 2 for adjustment. On the first pattern set black-level to the lowest setting where the bars numbered 17-25 flash. For the second pattern it may be more difficult to see 17 flash, and we suggest setting black-level no lower than where you can see 19-28 flash with typical viewing conditions. Some circumstances give the same black-level setting for chapters 1 and 2, and in other situations using the setting from chapter 2 serves as an acceptable compromise.
White- Level – Manufacturers may call this control contrast or picture, and chapters 2 and 3 allow for adjustments. Start by setting white- level very low so you can easily see the bars flash. Ideally you would want to see all the numbered bars 223-253 flash on these two patterns at a low setting, but in some situations the bars numbered 235-253 may never flash. Begin turning up white-level and watch to see if any bars stop flashing as you increase white -level. Generally we suggest using the highest setting available before 244 or lower disappear, but at minimum the 223-234 bars should always flash. On some displays the bars may not disappear even using the highest setting. The White Clipping description goes into further detail, and it includes other items related to white-level, such as color shift.
Color – Look at chapter 4 through a blue filter, or if available use a blue mode on the TV. Adjust the color control to find a setting where the flashing boxes labeled color most closely match the bar.
Tint – Some manufacturers may label this control hue instead of tint. Look at chapter 4 through a blue filter, or if the TV offers a blue mode that can also be used. Adjust the tint control so the flashing boxes marked tint most closely match the bar.
Sharpness – Go to chapter 5, and set sharpness low enough for no light edges to form on the black objects. On some TVs you will need to
avoid setting sharpness too low and causing the black objects to blur into the gray. If the black objects never lose definition or blur into the gray, then you may set sharpness to minimum.
