Mitsubishi HC6500 Home Theater Projector Review: General Performance-4

That’s about as tight as it gets. Too bad they weren’t all 250K cooler and it would be almost perfect.

Mike found that it was easier to get excellent grayscale balance starting with the Medium Color Temp than the Warm setting. Note, if you choose High Brightness color temp, you do not have access to those RGB settings to adjust the grayscale balance, thus, you can’t really calibrate the High Brightness mode.

White (100 IRE)6556K
Light gray (80 IRE)6510K
Medium gray (50 IRE)6507K
Low gray (30 IRE)6645K

After calibrating the gamma, followed by the RGB settings, and starting on the Medium Color Temp, we came up with these measurements (which we saved in User 1):

Note, the minor spike at 30 IRE (and that is minor) goes away by 20 IRE. We normally don’t report on 20 IRE or below, as our numbers aren’t that accurate down there, but with some projectors they tend to shift up or down in the lower brightness ranges, such as shifting towards red, in general in very dark areas. With the HC6500, the spike is small and then goes away.

No wonder the HC6500 looks so natural. That’s about as good as it gets. I think, probably only the InFocus IN83 in the past year, produced even better numbers, and that one is my favorite in terms of skin tones and overall color performance.

HC6500 Calibration settings for RGB

Contrast
Red-1
Green-6
Blue-11

These are the adjustments we made (in addition to the Brightness, Contrast, Gamma, etc., above), for “best mode”, User 1:

Brightness
Red-4
Green6
Blue-1
Gamma was manually set to:
High-3
Medium-3
Low-7

HC6500 Image Noise

Very good image noise performance, no jaggie issues, background image noise was typical 3LCD. 3:2 pull-down was good (most of my movie content is Blu-ray 24fps where it’s not needed), but I did watch segments of several standard DVD’s including Lord of the Rings, and found performance to be very good, in that regard.

Bottom line: No problem spotted, never needed to play with their Noise Reduction settings.
