As the Epson HC1440 is a projector that starts out with really good color, and because it's more of a bright room home "entertainment" projector than one designed for a dedicated home theater, I made the call not to perform a full calibration.

Thus, there is no "subscriber only" Advanced Calibration page.

But Mike did take a full set of measurements.

The first table (above) shows his recommended basic settings for each mode.

The second, below is a repeat of the lumens brightness table on the previous page, but we've added the color temp measured for white (100 IRE). The desired color temp, of course, is 6500K. so that all of these modes are close.

HC1440 Brightness, by Color Mode (mid-point on zoom)
Mode	Lumens	Color Temp (100IRE)
Dynamic	4722	6339
Bright Cinema	3623	6861
Cinema	3713	6374
Game	3541	6867

Finally, the last table shows the actual color temp measurements for each IRE (from dark gray to white) across the range for the Cinema mode.

HC1440 Color Measurements (of Cinema mode) by IRE
100 IRE	6861K
90 IRE	6824K
80 IRE	6750K
70 IRE	6711K
60 IRE	6660K
50 IRE	6591K
40 IRE	6573K
30 IRE	6469K
20 IRE	6647K

That gives you a pretty good idea of how accurate the color is. It is, in fact measuring closer to the desired 6500K than some far more expensive projectors with THX modes!

What we didn't do is adjust each individual primary and secondary color.

If this projector was calibrated fully, the color temp would get a very minimal adjustment if any (probably blue gain adjusted downward by 1), and that would be a minimal adjustment to the upper brightness ranges to reduce color temp by only a couple/few hundred degrees Kelvin (from mostly around 6700K down to the target 6500K.
