Mitsubishi HC7900DW Home Theater Projector Review
HC7900 in Eco-mode vs. Full power:
Lumen Output of Cinema mode on Low Lamp (All else on default settings) = 545 lumens vs. 713 lumens
That’s a drop of just over 25%. (But it does – per Mitsubishi – increase lamp life from 2000 to 5000 hours).
Mitsubishi HC7900DW Pre-Calibration Color temp, Cinema Mode
|Color Temp over IRE Range, Best Mode|
|A/V Memory 1 (or Video)|
Mike looked to find the best mode to start with, which he determined to be Cinema. Video, Game and 3D seem similar to Cinema , but Cinema has slightly better grayscale. Game and 3D have Brilliant Color turned on (Video and Cinema have it off), which has a number of effects, including cooling the picture – in the low 7000’s instead of the mid-upper 6000s.
|HC7900DW Color Temp over IRE Range – Post calibration:AV Memory 1 Mode|
Mike calibrated the Cinema mode (as a starting point for AV Memory 1), and came up with these results.
Average Gamma: 2.17
That’s a really tight set of numbers above. With the exception of full 100 IRE (white), which rises only slightly. The other settings are essentially dead on the money. The HC7900DW’s “white” doesn’t adjust very much when the lower brightness grayscale does.
Mike’s Notes: (repeated from last year) Unfortunately, Mitsubishi has decided to not allow access to even basic settings like Brightness and Contrast in anything but the A/V Memories. You can’t even change the lamp setting in anything but the A/V Memory modes.
Even if you start with Cinema, Video or any other mode as noted above, (default color temp is Medium for both Video and Cinema), selecting High Brightness Color Temp has the picture going straight to hell.
