DESC: The high definition WXGA resolution picture on the PRO1140HD is absolutely stunning in every way. A lot of technology went into creating this great picture. One thing that makes is possible is a Crystal Emissive Layer between the plasma glass and the individual light cells. This allows each cell to be charged and discharged three times faster than before, for greater light emission. So, blacks are blacker, yet the lighter areas on the screen still maintain their true brightness values and don't turn muddy or gray. Also improving detail is Pioneer's Advanced Continuous Emission (ACE) IV technology, which "smooths out" the visual steps between levels of color. With this enhancement, the panel can instantly identify the type of content shown on-screen (fast vs. slow motion scenes, dark vs. light scenes, etc.) and dynamically adjust the grayscale to create optimum detail. Pioneer's Active Dynamic Range Expander (DRE) improves contrast in the PRO1140HD.
