I heard and have the feeling that these colorimeters (i1 display) are going wrong over the years (dye issue), mine is 5 years old. I understand that if I do include the VCGT in the LUT, I must not install the profile (that will upload VCGT) ? Those monitors are used for video only, so OS wide ICC profile is not something I care about. We only use color managed application, and I made a custom OpenColorIO configuration with monitor color correction LUT at the end of the transforms. Thanks for your reply, so, to clarify, I have 2 types of devices :įrom what you say, it’s preferable to use the colorimeter (with its correction matrix) for speed issue ? Also some CCSS were created by other users in a wrong way… take a look on “i” button to plot gamut or spectral power distribution, gamut should be native = close to AdobeRGB green, close to P3 red on a current widegamut like that HP is upposed to be. Use displaycal colorimetr correction database if youdo not have an spectrophotometer, do not use its CCMX, only CCSS 3nm for i1d3. Remember to use proper colorimeter correction or (xrite spectrophotometers) high res 3nm mode. First is factory setting, second after internal calibration. Some sceenshots in attachment (display set to ). Those displays have internal calibration device, the color shift is worse after internal calibration. Here a screenshot of the calibration curve 6500K. We have a lot of HP Z27xG2 at the Studio, 50% of them seem to have a big white-point issue (image is green/blue) and it’s visually perceptible, is there anyone here having the same problem. If you want an accurate ICC system wide with grey corrected ouside your app woth LUT3D support Should I prefer calibrate/profile with tone curve set to “as measured” ?ĭepends on answer on 1st question answered above.Better an i1displaypro or even better a klein K10aĪnother couple of questions that comes in my mind : You can use i1Studio spectrophotometer at 3nm (Argyllcms high resolution mode) to correct colorimeters.Ĭolorimeter? You’ll need a faster one beacuse the number of displays. Spectrophotometer? You’ll need a colorimeter too and a very fast one if you need to measure such huge amount of displays and making a LUT3D ofr each one (17x17x17 =~ 5000 patches). What do you think about the quality of the X-rite i1 Studio ? Is it adapted to our job ?.I guess monitor native colorspace is preferred for calibration ?.If you do not need that, only to be accurate on that app you can include it on VCGT. If you want them to be accurate outside application using that software LUT3D, then VCGT should be on ICC at OS level, LUT3D profile should be measured with VCGT applied and LUT3D shoudl not include VCGT. Is it better to install a VCGT when using a video 3D LUT, or can I simply apply it in the LUT (with 3D LUT maker) ?.As I can extract S/N from EDID, I guess it’s possible to ask db to give me the correct ICC/3DLUT file to install, what do you think about it ? We do CGI, so a 3D LUT is more adapted to our needs, and I can include it in our OpenColorIO config, so that’s fine. I thought that I could make a correction database sorted out by serial number. The problem is that those monitors can move from one computer to another, so it’s quite complicated to calibrate/profile each time. I’m looking for a way to manage about 150 displays in our Studio.
