My questions on the original post are based on getting a proper and affordable spectrometer because:Ģ – Awhile ago, I invested in my displays, (OSEE XMC LCD 24” 10-bit LCD and Atomos SUMO 19). I’m a DIT and On-set colorist based in New York City

The news of the aging condition of the i1Display Pro is a great one. Vincent, thanks a lot for your detailed response. This reply was modified 5 years, 3 months ago by Vincent.

So… just use i1DisplayPro with proper CCSS.Īlso, keep in mind that LG calibration software does not uses a good spectral correction for that displays… but you have Displa圜AL. IMHO it will be most cost wise to invest $1000 in a good display with good uniformity (which it seems that LG is unable to offer in 2018) rather that spend that $1000 in an i1Pro2… unless you want to profile printers (in that situation it would be an awesome tool), but your messages show a more video oriented work. If you have lab grade spectrophotometer, this way is the best way to correct a colorimeter.Īnyway, if your displays are those LG31MU97 they seem to be GB-LED backlight and you don’t need to create a CCSS or buy a spectrophotometer, just use some GB-LED sample in Displa圜AL colorimeter correction database ( ) or RGphosphor from Xrite or “cleaned” version (last 4 row of spectral data) in RGphosphor CCSS from Xrite. Limited resolution of xrite spectros (10nm) does not look very promising with some backlight with narrow spectra like those in PFS phosphor LED. Unless you have acces to a lab grade equipment id the best one, and one CCSS do the job for all i1d3 measuring that kind of display.Īnother one is to create a matrix correction with an spectrophotometer correlating your particular colorimeter and your particular display.
This method uses CCSS (spectral data from your display) and colorimeter sensivity (per wavelength) stored in i1d3 firmware (which seems to be VERY accurate in order to recover differences between “your i1d3” and standard observer).
Then measure your displays with the i1DisplayPro and that CCSS. So you may want to create a CCSS file with an spectrophotometer (i1pro for example) and Displa圜AL which store the spectral power distribution of your displays (please NATIVE gamut, not emulated gamuts like sRGB or AdobeRGB). What you may worry about is that its spectral sensivity may be not equal to standard observer CIE 1931 2º. Correlation metering is available as well.I won’t bother about i1Displaypro aging at this point, it’s one of its strong points. SPAN displays level metering statistics, headroom estimation, and true peak clipping detection. SPAN also features output level metering with adjustable ballistics and integration time, EBU R128, K-system metering (including calibration K-system metering). SPAN supports multi-channel analysis, and can be set to display spectrums from two different channels or channel groups at the same time. Spectrum can be smoothed out visually for an easier examination. Beside that you can choose to display secondary spectrum of a desired type (e.g. You may specify Fourier block size in samples, FFT window overlap percentage, spectrum's visual slope.
SPAN provides you with a very flexible “mode” system which you can use to setup your spectrum analyzer preferences.
