Home › Forums › Help and Support › Bug? Color on verification always D 4.91
Hello. I’ve been trying to calibrate madvr. I have a i1 Display Studio and an LG OLED C2.
I have already done many calibrations before and never had this problem. Everything works as expected except one color is always wrong after verification.
I have attached the html. It is always R 26 G 0 B 0.
I am thinking this might be a bug but I am not quite sure. As you can see all colors are fine it is only one color that is wrong.
I have tried:
Doing more patches, less patches, the other pattern generator, different test chart.
The color is always exactly 4.91! Is seems a little weird that is it always exactly the same delta value.
I have compared the difference and visually there is not that much of a difference, it is noticeable but I would not say that much!
I am not quite sure what to do! Please help!

It’s black clipping on Red channel with newer i1d3, device reads “0”. Try to use latest Argyll or post your issue in ArgyllCMS mailist.
I noticed this after updating ArgyllCMS to 3.1 yesterday, could this be the problem? I can’t seem to find anywhere to download a older version tho…
OLED R black clipping issue is older than ArgyllCMS 3.1. Report issue to ArgyllCMS maillist including the exact colorimeter model so people will know if AIO measurement is available.
Ok will do! Is this issue only present on Verification or when profiling aswell? Does this mean my 3D Lut if wrong because of this?

everywhere R X G 0 B 0 goes bellow certain threshold

Check Ti3 file. IDNK if profiling patches included those dark reds.
