Απάντηση: ansi contrast VS on/off contrast
Mitsubishi HC7800
D65 low lampe 560 lumens και hi lampe 700 lumes ....η αντιθεση on/off ειναι 1400:1 - 1800:1
και μια αναφορα σχετικα με το θεμα μας απο το τεστ του προβολεα.
"For technical reasons trump DLP projectors in terms of epitome or ANSI contrast on, so does the HC7800, which is a contrast of 520:1 checkerboard significantly higher than nearly all competing technologies. This advantage is mitigated by a lower native on / off contrast that can be found in our list above. 1500:1 and 3000:1, with values between the limitations are especially evident in the presentation of darker scenes with a high proportion of black: the black level of the projector displays a light gray veil that surrounds these scenes like a fog. The engineers were aware of this drawback, apparently also because they have given the viewer a dynamic iris, the dark scenes in the luminous flux decreases and thus improves the black level."
