HP LP2475W Calinbration ?

[Moogle Stiltzkin]

Monitor: HP LP2475W
Os: Windows 7 64bit
Calibrator: EyeOneDisplay2
Software: Basiccolor Display


Before calibrating
-------------------------

1. set monitor to factory default.
2. set brightness to 0
3. the contrast i left as the factory default which was 80.
3. switch color to use custom. Left all RGB as 255
4. setup basiccolor calibration settings to the following:

- D65
- Gamma 2.2
- White and black luminance. White luminance: 120, black luminance: 0
- Profile type: 16 bit lut based
- chromatic adaptation: CAT02
- ICC v4






After calibration
----------------------

Brightness: 12

R: 255
G: 198
B: 218

Did i do any of the steps incorrectly? The best i could do was get contrast to 585 :/

Could it be that i should have set contrast to 100 before calibrating ???

The reason why you got not that good contrast ratio is because you had to drop Green level so low and had to compensate by increasing brightness. Try again, let you monitor warm up for hour before calibrating and move in carefull steps. I could get close to 700 on my old LP2475w.

If you are still not lucky, then I guess your particular monitors native whitepoint (they can vary a lot depending on batch) is so far from D65 that contrast is going to suffer no matter what. So instead of calibrating to D65, calibrate using your monitors native whitepoint (RGB sliders max) in Basiccolors settings. This way you can see what black depth and contrast ratio your monitor is capable of. Though image will probaply be too warm/cold, but you might get used to it.
