Here are some ideas on how to fix the colors without a meter.
For OTB settings, the high color modes look better on skin tones even though they are way too cool, but it does look ok with a few adjustments. I also think the refurbished units have completely different color tables, or else Art and PJC's settings are ridiculously over-saturated, because their settings aren't even ballpark on my unit. I haven't calibrated with a meter yet, although I've checked a few things. I will post a professional D65 calibration later. Everyone's setup varies, but here are some ideas on how to get rid of the main two problem areas, which are RED and Yellow Gain and Saturation. Since everyone's setup will be different, I'll give some ranges which might help until I edit this post after I do a professional calibration.
Color Mode: Standard
Video --> Saturation: 45-55 (leave at 50 at first, come back to this later)
Video --> Sharpness: 10
Video --> Tint:50
You can try Color Temp: Medium (you could also try High as it depends on lamp wear and some other stuff)
After doing this, go into User Color and drop the RED saturation, Yellow, and Green.
Red Hue = 0 | Red Saturation: 50-60 (depends on lamp wear) | Red Gain: 50-60
Yellow Hue = 0 | Yellow Saturation: 45-60 | Yellow Gain: 45-60
Green Hue = 0 | Green Saturation: 55-65 | Green Gain: 55-65
This is for ECO mode lamp. If you guys have a similar setup to mine and the lamp has worn the same (and it might not have, so don't get your hopes up, then these settings should look better).
If the skin tones still look bad, try going back to the Video setting and turning down the saturation more until skin tones look more natural, but don't turn it down so much to where the color overall has no POP or saturation in it. If the skin tones look to pale, turn the overall saturation in the VIDEO up a little.
If using High Color Temp instead of Medium, try increasing red to 50-70 on gain and saturation until you see a little red in the face start to appear at about the correct levels, but not too much red.
These settings accomplish the following, at least for me:
Reduce Red tinting in dark scenes and skin tones overall
Reduce Yellow tint and overly strong yellows in skin
Better looking and more natural skin tones
A more film-like image overall and not as overly saturated
After these adjustments, skin tones look really good in MOST bright scenes on my unit and pretty good in MOST dark scenes, but I can tell by eye there are still some gamma issues and tinting at certain levels of lighting, but it's much more mild than the default colors.
In making the above adjustments, there are some side effects, but I think the side effects you get are much less than how the projector's colors start out. I will do my best to get this projector exactly at D65 once I have time, but I can tell it's going to be tough, as this projector has a slight weakness with color accuracy (but I don't think it is a deal-breaker for most, especially at this price). If it's not a deal breaker for me, I'm assuming it shouldn't be for you (and I'm real picky).
I'll try to post the colorimeter readings next week, these readings are not a calibration, they are just done by my eye. I do not want to waste time calibrating until the lamp has 100 hours on it.
