I am new to calibrating my personal home projector and was wondering if you could clarify the CMS Calibration settings. Is it right to assume that these results are to be used for the “Natural” user only? What is to become of lets say the other set “users” It comes across as slightly confusing when there are settings for the “quick cal” but they are only for two specific User’s. Then on the next page, there is only an in depth setting for the “Normal” profile. Any help would be greatly appreciated.
Hi Larry, Short version, is that in theory, if you calibrate any preset mode, they should all end up about the same. Still, as manufacturers determine the characteristics of different modes, the result is some modes “calibrate more easily” which is to say, their settings are closer to what will be the final result. Thus we only one mode – plus we take the brightest mode, which sometimes is a true lamp native mode (the color system doesn’t balance the colors at all (usually strong yellow-greens). Most Dynamic modes are like that, but most have at least some ability to adjust. Thing is, as you correct for things like very strong yellow greens, the big difference in brightness goes away. So it’s no longer a much brighter mode. So our “quick cal” is a compromise – Mike tries to get as much improvement in the picture’s color as possible, without giving up more than 10% or so of the measured brightness before changes. In other words, you really only need a “best” and a “brightest” mode. Everything else is what may please you, but not necessarily particularly accurate. -art
I was hoping to see a comprehensive listing of all the reference calibration setting so I could systematically make the changes to each of the menu options. Do you have that?
Hi, We focus on one calibration, although mike provides us with the improved settings for things like brightness and contrast for all the modes.
The best mode in terms of out of the box color accuracy gets calibrated. With most projectors, if the brightest mode is substantially brighter we perform a “quick-cal” trying to improve the color and watchability as much as possible, but without sacrificing too many lumens.
The general settings and the grayscal color temp (RGB settings) are on the calibration page. The advanced calibration page has the individual color calibrations for the primary and secondary colors (RGBCMY). Access to the Advanced calibration pages is available to our subscribers ($3.99 per year). There’s no point in calibrating multiple modes, because for the most part, they would all end up looking the same. -art
