Dear all,
I am very new to this field. I hope this question would not be too supid.
I am currently trying to setup an experiment where I show images to subjects, and I need these images’ color to be very precise and correct, especaiily the Y value in the XYZ space. As a result, I need to make sure my monior (BenQ XL2420TE) is producing colors correctly, and I encounter some problems.
First, I cannot find a colorimeter correction file for my monior and colorimeter (i1Display Pro), and I am not so sure how this will affect my results. Do I actually need to buy a different device for my purpose?
Second, I notice that under the profiling tab, if I click the edit testchart, I can prvovide my own image for profiling by adding reference patches. However, I have 140 images that I want to include, but it seems like I cannot add all images at once? I tried to draw a very big image that combine all the images into one, but loading that image crash the dispcalGUI 3.0.4.3.
Any suggestions?
I would personally donate $20 if my question get compeltely sovled.Thank you.

That monitor has a TN panel, so viewing angle will be a problem.

That monitor should be a white LED, so you can use “LCD White LED IPS (WLED AC LG Samsuing)”.
Second, I notice that under the profiling tab, if I click the edit testchart, I can prvovide my own image for profiling by adding reference patches.
For profiling purposes, I’d recommend going with the “Auto” testchart setting instead of creating a custom chart. Set the patch amount slider to around 1000 patches.
Hi,
Thanks for the advice. May I have two followup questions?
About the viewing angle, I am wondering how much that will affect my results and is there a way that I can try to minimize the effect?
As for the suggestion for using the auto testchart, I am wondeering why you are suggesting that. Even if I only care about those colors that show up in the 140 images I have, I should not creating my own chart? Also, when you say patch amount slider do you mean “iterative patches”? And is there a way that I can test my images’ luminance afterward one by one in dispcalGUI?

Depends on how homogenous the screen looks.
and is there a way that I can try to minimize the effect?
Other than making sure to always have the same viewing position, no. TN is not suitable for color-critical work.
As for the suggestion for using the auto testchart, I am wondeering why you are suggesting that.
Because this will guarantee the best possible result, as it will take into account the screen characteristics.
Also, when you say patch amount slider do you mean “iterative patches”?
No, do not use the testchart editor. Set testchart to “Auto” and use the slider below to adjust the amount of patches.
And is there a way that I can test my images’ luminance afterward one by one in dispcalGUI?
No.
Hi,
A little tech issue…
You mention that my monitor should be a white LED, so I can use “LCD White LED IPS (WLED AC LG Samsuing)”. However, on this PC, I cannot find that option. I can see that option on my labtop though. Is it becasue my monitot is actually not a white LED? By the way, if I can borow a spectometer to do the correction, any suggestions on which one I should borrow? I suppose if I do it this way, it would be much more accurate?
Thank you.

Select “Import colorimeter corrections from other software” in the “Tools” menu.

Depends on what you can get your hands on. A Jeti 1211 will be more accurate than an i1 Pro, for example.
Sorry. I have one last question I think. After I used the spectometer to create the colorimeter correction, the system asked me to sleect a monito type. I am wondering if that matters, since I am not sure what type of monitor I have.
