Calibration Notes for 2017 LG OLED TVs

•

When calibrating SDR, LG recommends using a test pattern generator

set to output 18% area (or smaller) greyscale patterns with a black

background

•

When calibrating HDR, LG recommends using a test pattern generator

set to output 10% area (or smaller) greyscale patterns with a black

background

•

During HDR calibration, disable ‘Active HDR

’ (self generated dynamic

tone mapping) by setting the ‘Dynamic Contrast’ setting in the Expert

Picture Mode Settings to ‘Off’

•

After calibration, for best results, re-enable ‘Active HDR

’ by setting the

‘Dynamic Contrast’ setting in the Expert Picture Mode Settings to ‘Low’

•

For Dolby Vision calibration, CalMan 2017 must be used, along with a

test pattern generator compatible with Dolby Vision test patterns (e.g.

Murideo Six-G)

•

The ‘Edge Enhancer’ setting in the Expert Picture Mode Settings does

not increase sharpness; the default ‘On’ setting is a bypass function, and

is therefore recommended

•

20 HDR Calibration adjustment points have been provided for 540nit

content, 1,000nit content, and 4,000nit content, shown in the table

below. A test pattern generator should be set to output a grey patch at

the appropriated Code Value for each adjustment point. If using

CalMan, launch Levels Editor, and create a new set of levels using the

percentages in the table below, then select this range for the greyscale

adjustment in the settings tab of the HDR workﬂow.

*LG’s ‘Active HDR’ function analyses content on a frame by frame basis in real time, to determine metadata for the scene. This information is then used to adjust the HDR tone-curve to match the content, on a frame by frame basis. Control of the ‘Active HDR’ feature is found in the ‘Dynamic Contrast’ setting in the Expert Picture Settings menu.
