Contrast. The H9080FD boasts an on/off contrast rating of 100,000:1. In real-world terms, the projector's black level beats that of several traditional LCD, DLP, and LCOS projectors released recently. Since the LEDs can actually be turned off (or at least nearly turned off) when an all-black image is displayed, the H9080FD has an excellent black.
Where this projector really shines, though, is ANSI contrast. ANSI contrast describes the relative black and white levels that can appear in the same image at the same time - in other words, ANSI contrast measures the maximum contrast in any one particular image. In the past, the best projectors we've seen measured around 580:1 or 600:1, while many very good projectors measured 450:1 or lower.
This background information is provided in order to put the following number in perspective: the Vivitek H9080FD measured 844:1 ANSI contrast in our test lab. This is nearly half again as much as the next nearest competitor, and very impressive by any reasonable standard. The dynamic range on screen at any given time is broad enough to do justice to even the highest-contrast content available.
