    Hi all, first time I write on the forum as I have always found valuable answers and info.

    As in the title I’m having several issues with my iDisplay Pro meter reading calibrating my DLP Dual Laser Projector (model LG HU810PW).  White balance is impossible due to bad green reading from the meter, if it’s correct by measurement, by eyes the image seems present a strong green cast. I tried all meter positions, also direct reading with light diffuser which is slightly better but the issue persist. The issue is confirmed also with different software like HCFR.

    I don’t have a spectrometer, if you can reccoment me a suitable correction file I could give it a try.

    As meter setting I used telephoto mode, Projector profile, and Default Observer Type (could I pick something else for better results?)

    You need a matrix or spectral correction made for that laser projector and your i1d3. Since blue laser narrow spectral power distribution even at 3nm an i1Pro2 may not be good enough…

    Try the latest version of CC Profiler (formerly i1 Profiler):

    It won’t solve it, DisplayCAL catalog  cointains all EDRs from Xrite i1Profiler/CCProfiler, actually DisplayCAL catalog is bigger.

    He needs a custom CCSS or matrix correction for its laser projector… and even using it observer metameric failure may (will) happen (it’s a laser after all)

    Yes I confirm also with iProfiler software the issue is the same. The strange thing is users with Calman for LG auto calibration software (for a specific version of my PJ) seems work well with both XRite and SpiderX meters, maybe is embedded in the software already a correction profile?

    If you have an X-Rite colirimeter, you are eligible to free support from Calibrite:

    https://calibrite.com/us/calibrite-technical-support/

    It won’t hurt to ask them for the help you already paid for.

    I also highly recommend contacting X-Rite/Calibrite ambassador Art Suwasang:

    Maybe, look for EDR files in instalation folder

    Mostly an useless task. It’s an EDR related issue. If Xrite does not bundle it in retail software, it is a binary propietary format and has royalties
    a) they won’t provide de it to you (no more than detault EDRs)
    b) it won’t work with current software unless newer i1Profiler software under calibrite management has auto EDR detection on Xrite service folder… and that it hghly unlikely.
