Video Monitor Set-upMPFI Presentation by Steve Brown, 10-20 Productions, 6/13/06 1. Using Color Bars (preferably SMPTE), set monitor to “Blue Only” (or “Blue Gun”). On some monitors, this will show black and blue vertical bars, but on many newer monitors, the vertical bars will be gray and black. 2. Adjust Chroma and Hue (which may be designated Color and Tint or Saturation and Hue) so that the vertical bars are identical alternating blue (or gray) and black bars. With SMPTE bars, there is a second set of small color chips below the large bars that should match the “Blue Only” colors (blue or gray and black). 3. De-select the “Blue Only” feature so that normal color bars are visible. 4. Adjust Brightness so that only the chip on right of the three PLUGE* bars is visibly brighter than black. In other words, the bar on the left of the three PLUGE bars should not be visibly separate from the middle bar. 5. Adjust Contrast so that the 100% white chip does not glow. Unlike the rest of the adjustment, this requires a somewhat subjective decision. There are new versions of color bars that have a graduated gray scale in the lower portion of the pattern, which may aid in this adjustment. If your monitor does not have a “Blue Only” feature, the same effect can be achieved by viewing color bars through a Wratten 47B filter, which is available at many photography stores. *PLUGE (Picture Line-Up Generating Equipment) – The PLUGE signal was designed for rapid and accurate adjustment of the black level, reference and, hence, the luminance range, display. It provides adjacent vertical bars, one at black level, reference and continuous bars slightly above and slightly below that reference. Following initial development by the BBC, CCIR now recognizes at least eight versions. SMPTE EG 1-1990 includes a variant in which the black level, reference is flanked by bars at –4 IRE and +4 IRE. When the –4 IRE merges into the black level, reference bar, but the +4 IRE bar is distinguishable, black level, reference is correctly set. A white patch is included at peak white, to define IRE 100, and the luminance range, display CRT. Tektronix Glossary of Video Terms and Acronyms Leader Application Notes |
