I know I have read about the xrite i1 display pro and there are different firmware versions. I just want to get a good starter calibration meter or bundle(meter,dvd, software or other stuff). Is there some other place I should be looking at other than amazon?
What other recommendations do you all have for getting started down this path? Do I need a blu-ray/dvd calibration disk?
Hi, If you decide to get your own meter and start the journey, the ideal meter to get is the X-Rite i1Display PRO and if you want to improve it more, you can add a spectrophotometer (like i1PRO2, as future step of color accuracy upgrade) to use it for creating a unique meter correction table for each of your displays/projectors, to improve your colorimeter color accuracy. To see why you need both or a lot of other details generally about these 2 meters see there
. But starting from the colorimeter (i1Display PRO) is a proper and ideal start for all, for the budget you have to spend. To the linked page of X-Rite, its explaining the difference between OEM vs. Retail i1Display PRO.
For example if you have a high-brighntess LCD like the Samsung Q9FN can output about 1700-1800 nits peak white, the i1Display PRO Retail has certified to measure up to 1000nits, while the i1Display PRO OEM has certified to measure up to 2000 nits.
About that peak output difference, it doesn't mean that the Retail version will stop the readings at 1000 nits; it can read higher; beyond 2000 nits, but X-Rite is not certify/check that the measurement you will see it will be accurate.
Any calibration software for manual calibration using normal OSD menus can provide you the exact the same end results, since its a graphical presentation of what your meter is reading. So when you perform manual cal, whatever software you will use, the end results will be the same, the interface is different only.
About calibration software there free solutions, you can download:
1) HCFR from here
with support forum topic: HCFR - Open source projector and display calibration software
2) The Free DPS version of LightSpace CMS
can be used also with an i1Display PRO meter, there available to read various guides
on the Light Illusion website.
The specific guide for use with LightSpace DPS is here
But there is a lot of potentially useful/interesting info in the various guides on the website also.
Support forum topic: Free LightSpace DPS - Manual Display Calibration
There is a HCFR tutorial from a forum member here: The certainly not complete user guide to get to know and calibrate your TV
After selecting your calibration software, you have to find a calibration disk which had been created specifically for each software because there differences between calibration disk that can affect the final result when you will use not proper patterns for each measurement run.
You will playback the calibration disk from the source you use to playback your movies, to include to the adjustments you will make any player internal processing/colorspace conversions inaccuracies, to have your full video chain calibrated.
You will need to get some patterns for measurements for SDR (REC.709) and for HDR10 (REC.2020).
For example, the calibration steps it will be to measure and find your device most accurate picture mode (cinema/isf/professional etc.) finding out what TV colorspace option provides better color gamut tracking of you target gamut (use 5-Point Saturation Sweep to find out), then check what color temp mode has less RGB balance errors, then do the same with gamma presets...to find out which setting provide you closer tracking of your target gamma....then check contrast/brightness/color for clipping, start with 2-Point RGB balance using 30% Gray and 100% White patterns (fix using RGB-High controls RGB balance errors only...while with backlight/oled light handle and set the peak output you want)....then after a lot of back/forth between these 2 measurements and by checking again contrast/brightness, you will move to 10 or 20-Point adjustments....after the end of grayscale calibration (and by checking again contrast/brightness) you move to CMS calibration and after the end of CMS you re-check Grayscale and CMS again for smaller re-adjustments.
