1. Is it possible to calibrate DV without the VideoForge PRO? SpectraCal said no (via email), but some posts on here act like it is built into CalMan. If so, does the Enthusiast version allow this?
2. I see talk about the issues with colorimeters and LG OLEDs, but is the i1Display good enough to use for home, i.e. non-professional results?
3. How many settings need to be calibrated? It seems that the TV has separate settings for each input and then for SDR, HD, 4K SDR, 4K HDR, 4K HDR10, DV, and others? For each color space? Going through the RM UHD|HDR-10 Test Pattern Suite, it seems like there are numerous things to calibrate.
Any help or advice is much appreciated!
1) About Dolby Vision Patch generation, if you have a notebook with accurate 1080p60 8-bit RGB output, you can use it as pattern generator for Dolby Vision using CalMAN's (Enthusiast) internal software generator, you will need HD Fury Integral to add the LG (display specific) additional infoframe to trigger DV mode of LG.
For LG OLED's 2017, they have the capability to upload via USB new settings for the DV tone mapping to the TV internally, you need to trigger DV Relative mode...which bypass the internal DV tone mapping of the display and you calibrate for Power Law Gamma 2.2 as target because DV expect a calibrated 2.2 Gamma display to apply their internal mapping....and then after uploading the new DV file to the display internally, you take post-cal measurements with DV Absolute mode.
2) You can use i1Display PRO, just not the OLED table the meter is coming, but select the default (factory calibrated table). (Zoyd has confirmed this by comparing the OLED and Generic table using his JETI 1211 with LG B7 before some days.)
X-Rite used a Sony PVM-2541 RGB OLED Monitor to create the OLED spectral correction for i1Display PRO which can be useful when you will measure the Sony or FSI (Flanders Scientific Inc.) RGB OLED Broadcasting Monitors and not a consumer LG WRGB OLED or the following brands which are using LG's WRGB OLED panel also: Sony, Panasonic, Toshiba, Loewe, Philips, Skyworth, Metz, Grundig, Vestel, Arçelik and Bang & Olufsen.
A lot of info for X-Rite meters you can find there: http://www.displaycalibrations.com/x...ions_info.html
3) For SDR 1080p, SDR 4K, HD, you need one calibration, for REC.709, and patterns for REC.709. If you like do a secondary for REC.709 with more peak output to use it for day/lights-on view.
For HDR10 you will use the Ryan's patterns you have.
For DV you will use CM, a bit-perfect PC/Notebook RGB output and HD Intergral.
