Same monitor with different color rendering?

I use a monitor for my PC and now and then also for my laptop. I noticed that when I plug it into the laptop, the colors are pretty washed out. The monitor is identified by both systems.

What could I do to achieve the same color reproduction on laptop + monitor as on PC + monitor?

Get Datacolor Spyderhttp://Datacolor%20Spyder and calibrate the screen properly.

It could be that the laptop and PC use different color profiles.

Each screen has an EDID (Extended Display Identification Data)

Your laptop / PC reads this out every time and checks which color profile can be used.

The EDID consists of bytes.
The 24th byte contains which color profile is to be used, e.g. "RGB 4: 4: 4" or "RGB 4: 4: 4 + YCrCb 4: 4: 4"

For example, if the screen If the profile makes a mistake or the wrong one is selected, you get strange colors.

With laptops it often happens with Apple computers that they do not read the EDID correctly.

The other thing could be that you just don't have the right profile installed on the laptop.

Go to your manufacturer, including your monitor. Then download and download the monitor driver (not graphics driver)

Most of the time it could be enough to install the driver.
But it could also be that it doesn't work.
When downloading the driver you will get a zip file. This contains an icm or icc file. Or you can find an icm or icc file on the website.

You can simply add this to Windows.
For this you do this:

Open "Color Management"

In the Device tab, click on Use my Settings. And then click the "Add" or "Add" button at the bottom left.
Then click on "Browse" and select the ICM / icc file.

that's it then.

You can also reset the color profiles in the Windows Color Management program.

If all of that doesn't work, you can configure the screen yourself. Often in your graphics card settings.

Calibrating a monitor or setting it correctly is possible with good instructions. Here are some pages that describe it well:

Somewhat more demanding:

Calibration using free tools:

And a little easier:

When it comes to monitor calibration, I differentiate between the normal user and the professional graphic artist, who needs an absolutely precise setting of all values, especially the color settings. When switching from one monitor to another, the color reproduction must always be the same.

This goes so far that, ideally, he does his job in a workplace where the ambient light is always the same. Even the lamps used must have the same color temperature when they are replaced.

If the claim is not so high, it is purely visual with test images, here are good instructions with test images to download:

The professionals also use a color calorimeter, in your case rather unnecessary.
