When the user will know the Peak Luminance parameter value, then any custom adjustment upload of other parameters it will not alter/undo the current calibration, it will only change the tone-mapping behavior. This is a detail the user has to discuss with the professional calibrator first, before adjusting the Peak Luminance parameter. When the user has calibrated the display using HDR10 patterns, it will be required to set his measured 100% White calibrated peak output 'nits' to the 'Peak Luminance' parameter value.įor users without any calibration instrument/software who want only to test different tone-mapping parameters, then the default '700' nits value to the 'Peak Luminance' parameter should be used.įor users with calibrated displays from professional calibrators, its not recommended to change any value unless they can get the info from their professional calibrator of what value for Peak Luminance parameter its been uploaded after calibration, as there no way to see what value the professional calibrator has entered internally to the LG 2019 OLED TV.Īs a tip, the panel Peak Luminance number in nits can be found to the professional calibrator post-verification grayscale report.

It doesn't matter what calibration software will be used to calibrate the LG 2019 OLED TV in HDR10 mode. That template can be used from any LG 2019 OLED TV user, even if his display has been calibrated or not. LG 2019 OLED TV's PQ Curve Upload Template is providing a GUI (Graphical User Interface) to configure and upload these 7 tone-mapping engine calculation parameters data values to the TV, to match the actual measured (calibrated) peak luminance of your display for the tone-mapping calculations to be more accurate and also to adjust the roll-off point for 3 different user-specified mastering display peak values (Maximum Display Luminance of HDR10 ST.2086 static metadata) of your HDR10 content.

When Dynamic Tone Mapping is disabled 'Off', the LG TV will use the default 'factory' HDR10 tone curve parameters (Peak Luminance, 3x Tone Curve Metadata Point and 3x Roll-Off Point) and will determinate the PQ Luminance of content based to the HDR10 compliant stream static metadata info (SMPTE ST.2086, MaxFALL and MaxCLL) as follows:ġ) Use ST.2086 Mastering Metadata -> Mastering Display Color Volume -> 'Maximum Display Luminance' value.Ģ) If 'MaxCLL' (Content Metadata -> Maximum Content Light Level) is present and lower than the 'Maximum Display Luminance' value, it will use MaxCLL value.ģ) If ST.2086 Maximum Display Luminance and MaxCLL are both signaled as zero (as defined for un-available), it assumes and use 4000 nits values as 'Maximum Display Luminance'. When Dynamic Tone Mapping is enabled 'On', the HDR10 tone-mapping curve will be dynamically generated after analysis of signal peak and histogram information on a frame by frame basis. LG 2019 OLED TV's feature a Dynamic Tone Mapping algorithm (Picture -> Picture Mode - Setting -> Expert Controls).

How to use the LG 2019 PQ Curve Upload Template for DeviceControl Interface with LG 2019 OLED TV's. The extra software which DeviceControl Interface using is available inside the ‘extra_software’ directory.

When DeviceControl Interface will connect with the LG OLED TV, it will require local network connection only, it will not require any active internet connection.Īll the DeviceControl Interface code is open source and anytime the user can see what the software is doing. When the user want to download any LG Template for DeviceControl Interface from a facility or office where the internet connection capabilities are limited or secured, then the user can download the LG Templates from his home or temporary enable a WiFi-spot from a mobile phone only and connect the notebook with the DeviceControl Interface installed to that temp network for some seconds, just for downloading only the LG Templates.

Once the user will download any LG Template, the software will work in offline mode, there will be no call to the cloud unless the user will click to About Menu, to check if there any newer version of DeviceControl Interface available for download.ĭeviceControl Interface will not connect with any web-server unless the user will click to check for LG Templates or DeviceControl Interface updates.

Can I safely use DeviceControl Interface?ĭeviceControl Interface will install a web-server which provides the capability to registered users to publish or download any template shared by other users.ĭeviceControl Interface will require internet connection only when the user will select to refresh the cloud to check if there available for download any newer LG Template version or when the user will actually download a specific template to his system.Įach LG Template will require a file download with size between 24 KB (min) - 2 MB (max).
