... Only the finest displays maintain a constant black-level with large changes in APL. In the majority of CRT-based displays the black-level adjustment must be a compromise over a range of APLs. The BK-1253 provides a Window pattern with PLUGE bars, so the APL may be altered to make the best setting. ...
Page 25
... Black-level should be adjusted at the beginning of a complete display calibration. It must also be monitored and re- adjusted during the display calibration process. The Black-level adjustment often interacts with the Contrast adjustment and will change during the Color Temperature and Grayscale Tracking adjustments. The BK-1253 provides unique calibration patterns to monitor and re-adjust black-level while making those adjustments. ...

... BK-1253 Contrast Adjustment Patterns: The BK-1253 has several patterns that can be used together to determine the best operating point for the Contrast control. These include the Window, Multiburst, PLUGE, Needle, Overscan-Bounce , and Grey Raster patterns. ...

... CRTs are adjusted later for the best convergence. BK-1253 Geometry Adjustment Patterns: Cross Hatch The BK-1253 includes a 16:9 Crosshatch with vertical and horizontal white lines against a black background. The grid pattern produces square cells on a HDTV monitor for easy adjustment or measurement of horizontal and vertical linearity. ...

... LCD and DLP projectors because their convergence is mechanical in nature and should have been permanently adjusted at the factory. BK-1253 Convergence Adjustment Patterns: The 16:9 Crosshatch pattern is the ideal pattern for adjusting convergence. Each of the three primary colors should overlap the others without color fringing ...

... If that happens use the Contrast control to reduce the peak-white level so that both boxes are distinctly visible again. The BK-1253 also provides a Horizontal Luminance Linearity Staircase pattern with 10-IRE steps from 0 to 100 IRE to verify the color temperature at other luminance values. These patterns should appear to have a constant color temperature ...

... If the display includes Sharpness or Detail Enhancement controls they should be calibrated to maximize apparent picture resolution, but avoid any excessive edge-enhancement that creates outlining artifacts. BK-1253 Sharpness/Detail Enhancement Calibration Patterns: Sharpness/Detail Enhancement Adjustment Procedure: Initially adjust Sharpness or Detail Enhancement controls such that each of the black and white line bursts (except the last burst) in Multiburst pattern appear to have the same black/white contrast ratio ...
