Changing laptop LCD color temperature(white point)

Does anybody know a certain software in Windows 7 to change the color temperature(white point) on a laptop LCD? Namely on a Sager( Clevo P170SM-A) with core i7 4810qm , intel HD 4600. Thanks.

 

not that I have ever found, that tends to be more of an issue with the backlight and lamps. most consumer laptops including the rMBP's cant seem to do a lot about it, only very high end wide gamut panels in a few portable workstations can run accurate whitepoints.

the best you can to do is get closer color matching, use a good hardware screen calibrator like a spyder 4 etc. it will really help but may not get you as close as you like.

 

The software that comes with display calibration systems such as the Spyder products does just that: They create modified display (ICC) profiles that are then loaded into your graphics card. However, they require a hardware sensor for this function. So, it is possible in principle to do this, but I don't know of any stand-alone software solutions. It is conceivable that somebody might offer ICC profiles for various color temperatures of a given LCD panel, but I haven't seen these anywhere. The reason might be that somebody worrying about color temperature is likely to be interested in some amount of accuracy, which is only possible with a sensor-based solution.

P.S.: Perhaps this software is what you want? It's free, too.

 

hardware calibrators work on color and not whitepoint though, that is a function of the backlight itself. ( unless it is an AMOLED screen or CRT )

 

No; by adjusting color intensity you can adjust the whitepoint. Remember, the white you see is created via a mixture of the individual color subpixel intensities. So, yes, all color calibrators let you adjust the whitepoint. This is independent of screen technology, and in Windows is implemented through a defined interface which is hardware independent.

 

Thanks for all the info guys it was verry helpfull. I've tried f.lux and it works, but all it does is make the screen warmer depending on the time of day. There is no manual mode for it so I guess I'll just have to buy an external calibrator. thx again

 

Is this really possible? I changed the CCFL backlight in one of my laptops for an LED backlight. I kept the same LCD screen, however. After the change, the whites ended up looking quite yellowish.

 

no, you can get a minor tweak but nothing too accurate since whitepoint is the lack of any pixels being lit and is purely the backlight used in the panel, as you found out. very few screens have a manual adjustment capability or made for an accurate whitepoint. hence why the contrast and blacks are their big marketing words.

 

Hardware calibrator does do whitepoint?

Calibration itself is whitepont and gamma, where profiling is color.

If you don't need to hit a exact number, probably try some of those software that allow loading calibration curves. Monitor calibration wizard is a popular one.
