Tuning color The HP DreamColor Display Calibration Solution purchased separately can be used to calibrate the displays in a video wall to ensure that their output closely matches each other This prevents visible differences in the composite image due to variations in color temperature luminance or gamut the range of colors among the displays It can also be useful to calibrate displays that are not in a video wall but which should match each other as when they are in the same room The HP LD4730 and LD4730G displays contain an internal color management engine and calibration processing hardware allowing calibration without the use of an external computer the colorimeter contained in the HP DreamColor Display Calibration Solution is all that is required Calibration is performed on each display in a video wall and can be done before or after the wall is assembled It may be easier to calibrate the displays prior to wall assembly because the colorimeter must be connected to the USB port on the back of the display Since you might want to recalibrate a video wall after it has been installed HP recommends using scissor mounts or some other type that allows you to move each display out from the wall and access the USB port For a permanent wall installation a rack mount USB extender facilitates access to the USB ports ENWW Tuning color 47 In preparing to calibrate a display or video wall observe the following guidelines e Decide how brig
