Windows 7 Color Management - Display ICC Setting Method

Since using Windows 7, it has been found that Windows 7 does not automatically call the monitor ICC file after color correction. Even when manually switching the icc file, the color does not follow the conversion (this means that the graphics card LUT corresponding to icc is not uploaded to the display adapter), obviously its operation mechanism is inconsistent with XP. However, since Windows 7 will reset the display adapter LUT to zero under certain conditions, it is necessary to start the built-in mechanism of Windows to have a way to automatically copy the LUT back after the video card is zeroed. As for Eizo's CG series color correction, there is no need to change the graphics card LUT, so no problems have ever been encountered. It should be noted here that the ICC file generated after using the color correction device must be used in conjunction with the corresponding graphics card LUT, otherwise it is a no-brainer (because the ICC file records the screen characteristic value after the graphics card LUT is changed). It's easy to see if Windows 7 has settings to use ICC, but it doesn't know if the graphics card LUT has been updated. Although the resident program of the color correction device will help load the LUT to the display adapter at boot time, the LUT will be reset to zero after a period of use. The software attached to Eizo's CG display will detect that the graphics card LUT is going to be changed by Windows 7 and the prompt message appears, so it seems that Windows 7 has some unknown mechanism to brush the graphics card LUT. After repeated verification, it is found that the Windows 7 system does not automatically change the graphics card LUT corresponding to the icc file by default, so that you must manually turn on the color correction program after you have finished color correction, otherwise its operation will not be normal. So I spent a little time researching and found that just by modifying the settings of Windows 7, I can make the color correction file automatically load and automatically change the graphics card LUT, and can reply to the set of LUTs corresponding to the ICC file when the Windows 7 is swiping the LUT. . Although some friends who use the color correction device do not think that Windows 7 has something wrong with the operation, I suggest that you should follow the method to make sure that your school color work can work normally. The modification method is as follows: 1. Press the right mouse button on the desktop to select the screen resolution, then the following figure appears:

2. After selecting [Advanced Settings] in the red box of Figure 1, the following figure will appear: 3. Select the [Color Management] page as follows: 4. Click the [Color Management] button and the next screen will appear: 5. Select the [Device] drop-down menu to select the monitor you are using: Under normal circumstances, the above image [Use my settings for this device] should be checked. And you use the color correction device to help you correct the icc file, usually the one that is indicated (default) in the [configuration file associated with this device]. In the state of automation, if you click on other ICC files here and change it to (default), the color of the screen must be changed immediately, which means that Windows has the corresponding LCU of the ICC file. . If not, it is unfortunate that your icc file is not automatically loaded by Windows 7, causing the graphics card LUT not to be updated as planned, so the color does not match the result of your correction. 6. Press the [Advanced] page to see what it looks like in the inside: You will find [Use Windows Monitor Calibration] (blue position in the picture) that checkbox is not checked and still cannot be selected. In fact, as long as you can make it hooked up, you can let Windows 7 automatically load your icc file and change the corresponding value of the graphics card LUT to the school color. 7. After pressing the [Change System Defaults] button, you will see this screen: 8. Click on the [Advanced] page and you will see the following image. You find that [Use Windows Monitor Calibration] is finally available. Select the status (blue position in the picture): 9 This is the key point, check [Use Windows Monitor Calibration]: 10. After the above screen [Close], you will see the [Color Management] window, you can Found [Use Windows monitor calibration], although it is reversed, it has been checked: After the above steps, you just press [Close], Windows 7 will automatically load and apply your ICC file, without happening Synchronized things. You may wish to return to the bottom of the window in step 5 and apply the other icc files to the default values. The screen color should change synchronously, indicating that your settings have been successfully operated.
