Mitsubishi HC7800D Home Theater Projector Review

That’s a really tight set of numbers above. Mike’s calibration is almost dead on the money, just the tiniest bit warm.

Mike’s Notes: 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.

Turning Brilliant Color on increases lumen output, but to the detriment of grayscale.  Calibrating with BC on brings the lumen output down close what it is with BC off. 

Grayscale was quite good after calibration.  Using the 2.4 gamma setting increases average gamma to 2.34, so there’s no stock setting that gets gamma into the 2.2 range.  It can be achieved with the custom gamma settings, however.  High Brightness cannot be selected as a reference color temp in the A/V Memories, so there no way to get a high brightness quick cal.  The best bet is to use an A/V Memory with BC on, but that’s only 150 lumens above the calibrated mode.

There are two color gamut settings (see the CIE charts), Wide and Normal, but there’s not a lot of difference between them.  Both have an expanded Green gamut. 

In 3D mode, you can use either the 3D picture mode or the User mode.  I measured a white area on a 3D Blu-ray with both and got 657 lumens with User mode and 606 lumens with 3D mode.
