How that thing works? i dont understand... you just put the 3Dlut, start the program and you totally forget about the TV and when you come back, it's calibrated? How? that thing is capable of touch the internal controls of the TV or what?, too bad i cannot spent more money right now
Also a 10/10 to www.chromapure.co.uk
, if someone is from europe and wants to buy a profiled i1D3 like me, they're the best, answered so fast to everything, also they told me that my i1D3 has been profiled using a B6 too, cannot wait until friday to start my adventure in the terrorific world of calibration!
Hi, eeColor 3D LUT Box is for SDR signal (up to 1080p60 12bit) and for it's price the value for it's money has the highest ratio from any other calibration gear (see there all options available for HT market
For 3D LUT, you need only to prepare the display doing basic adjusments only, after initially settings brightness/contrast/sharpness...you don't need to do any serious pre-calibration with LG (since it's internal controls are not working very well), you select the native gamut and do only 100% White with RGB-High from internal controls while you keep an eye for your desired peak output level you will have while you adjusting RGB-Gains and OLED-Light.
After they you start the cube measurements and then you upload the 3D LUT correction file to eeColor 3D LUT Box. After that you take post-verification measurements.
It requires basic calibration skills.
I have posted some results from 3D LUT in a LG OLED here
, and Pioneer KURO there
; using LightSpace with eeColor 3D LUT Box.
Moving to 3D LUT, it will save you some thousand new hours of trying different patterns and different values of internal calibration controls to minimize your color errors.
For 4K Input you need Lumagen PRO (which cost mimimum about $5000) and a calibration software to use it (+$400) while eeColor 3D LUT Box can work with free open source like DisplayCAL/ArgyllCMS (get low cost Google's ChromaCast for thousand color patch generation), so this keeps the total cost very low, to enter to 3D LUT display characterization world....while it's working with CalMAN Enthousiast/LightSpace HTL as minimum also.
So for SDR if you have Lumagen PRO (17-Point Cube + 21-Point Grayscale....4934 color points) or eeColor (65-Point Cube....274625 Color Points) it's obviously that you can have more points to specific areas where you display is more problematic and generally use more points (+5000 real measurements) with eeColor, so for SDR is the king of correction.
I have posted the difference in post-calibration verification between 17-Point Cube (4913 color patch measurements) and 21-Point Cube (9261 color patch measurements) here: https://www.avsforum.com/forum/139-di...l#post51515377
Even if you get Lumagen PRO, you can do only SDR with 3D LUT box with any consumer display, not HDR 4K 3D LUT.
Even if you spend at least $5000 for a Lumagen PRO, you can't do 3D LUT for HDR with consumer displays, because you can't have active 2 tone/gamut tone mappings. (one if the internal display and one from the 3D LUT Box). So even if there will be released an HDR 3D LUT box with $1 price, you cant do HDR with current consumer TV's.
If you calibrate HDR with internal controls and have calibrated 750nits it doesn't mean that gamut mapping starts at 750 nits and above, it's unknown what each model / with each firmware is doing, to LG's it's starting lower. (the idea to use the 3D LUT box only to fix below 750nits will not work)
If you trick the UHD Player that you have a connected 4K HDR display (with HD Linker) so to force it output 4K HDR REC.2020 but remove the metadata from the signal so the TV will not enter to HDR mode...but receive full 2160p ST.2084 REC2020 10bit (so it will not activate any internal tone/gamut mapping) then the LG calibrated peak output is only 450nits, which is not enough for HDR effect. If you do this trick, then yes, you can use create 3D LUT for ST.2048 REC.2020..but for 450nits only.
In an ideal consumer world for HDR, we need to have an option to disable any internal gamut/tone mapping (something broadcasting HDR monitors are doing...since they don't do any mapping internally.)..and use 3D LUT capable devices (like Lumagen PRO) to do all the stuff with a proper software like LightSpace, so the TV to be able to output the same peak output (750nits) with or without HDR signal.
FSI's Monitors CEO, has found a service menu setting in LG 2017 C7 model which it can enable the full display peak output (750-800 nits) without requiring HDR metadata over the HDMI connection and without triggering a ST2084 EOTF. If this work then you will be able to use Lumagen PRO to create a 3D LUT 2160p with HDR for LG 2017 OLED and once more info will be available, it will be tested for LG 2016 models also, here Steve Shaw posted about this: http://www.liftgammagain.com/forum/i...-hdr-tvs.8625/
