我使用spyder4校色仪给LG 27GL850显示器校色，根据软件说明我应该先选择好spyder4的校正文件，当我在Colorimeter Corrections Database网站搜索我的显示器型号时，它列出了不同的校正文件。有的是ccss类型，有的是ccmx类型，并且在不同的类型下，还有不同的文件可选。我随便选择了几个进行校正前的测试，发现仪器的读数各不相同。
我想问的问题是，这些校正文件都有什么区别？我应该具体选择哪一个文件呢？虽然它都是对应27GL850，但明显最终校正的结果是各不相同的，哪一个校正结果又是准确的呢？另外，如果这些校正文件我都不选择，而是直接在测量模式中选择液晶（常规），这是最保险的做法吗？如果它是最保险的做法，为什么又需要这些校正文件的存在呢？
I used the Spyder4 colorimeter to calibrate my LG 27GL850 monitor. According to the software instructions, I should first select the correct correction file for the Spyder4. When I searched for my monitor model on the Colorimeter Corrections Database website, it listed different correction files—some in .ccss format and others in .ccmx format. Within each type, there were also multiple files to choose from. I randomly selected a few for pre-calibration testing and found that the instrument’s readings varied.
My questions are:
1. What are the differences between these correction files?
2. Which specific file should I choose? Even though they all correspond to the 27GL850, the final calibration results clearly differ—so which one is accurate?
3. If I don’t select any of these correction files and instead choose “LCD (Generic)” in the measurement mode, is this the safest approach?
4. If this is indeed the safest method, why do these correction files exist in the first place?

IDNK, plot them. Argyll’s “speclot.exe PATH_TO_A_CCSS_FILE”
2. Which specific file should I choose? Even though they all correspond to the 27GL850, the final calibration results clearly differ—so which one is accurate?
Since you have an spyder… all will be innacurate. Because Spyders. CCSS accuracy relies on that device’s reported spectral sensivities match actual sensivity.
Spyder4/5 are very innacurate devices, undrstanding this innacuracy as I said rather tahh out of the box innacuracy with no correction selected.
Maybe you should stay with default modes (upper right combo) rather than CCSS, or buy an i1d3 from Calibrite/Xrite.If display is sRGB only, mode white led
If widegamut LED, I do not remember teh label , something like “wide led” or “RGB led”3. If I don’t select any of these correction files and instead choose “LCD (Generic)” in the measurement mode, is this the safest approach?
Use the closest “mode” built in device…. but the chances are that this will be innacuarte to
4. If this is indeed the safest method, why do these correction files exist in the first place?
They exist for accurate devices like i1d3 from Xrite.
