As a total nooob, I need help. I'm stuck and can't find my way out. Here is the story:
Currently I'm using a Panasonic DVD-S97 DVD player with my Hitachi 32LD7200 LCD display. I'm using a HDMI connection and DVD player is set to RGB mode. I'm using a Eye-One Display LT probe and HCFR program and I'm trying to calibrate my LCD display. It's been a few days that I'm struggling but yet the secondary colors are WAY off
My LCD has 3 main sections in the menus for calibration of color:
- Color temperature (Red, Green, Blue Amplitude and Cut-off)
- Color management (Magenta, Red, Yellow, Green, Cyan and Blue sliders)
- Color decoder (Red, Green, Colour, Hue)
Also I have Brightness, Contrast, Backlight, Colour and Hue in the general menu. All these options are active when I use the HDMI-RGB input.
Using DVE and HCFR, I could set the brightness, contrast and backlight to achieve a decent contrast ratio of 650 with nice blacks and whites. Also I could use the color temperature settings to get gamma and white point to an acceptable level (Delta E less than 4 above 30 IRE). This was the easy part and I could do it in less than hour.
The difficult part or the rather impossible part for me (I'm working on it now for 3 days!) is to get the secondaries right: No matter how hard I try, all the time two of them remain way off (I'm talking about situations like when Cyan is actually halfway between blue and cyan targets!).
Last night I noticed something that maybe the key to my problems: I read four saturation levels for each of the secondaries (0, 25, 50, 75 and 100% lvls). I noticed that by increasing the saturation, secondaries start from D65 point and go toward their target point in a nice linear fashion, however, this only happens until the 75% saturation levels (where they are awfully close to the CMY targets) and when the saturation gets to 100%, the secondaries suddenly go far away from their target values. I feel it is like there is a GAIN for the secondaries that is too high so they get saturated too early. I don't know how to fix this problem and which controls to play with. Should I be able to fix this problem with those Color management settings? What exactly they are supposed to do? I could not figure out their function by playing with them. Any help or suggestion would be highly appreciated.
