“With Vivid selected, the film looks stunning, combining bright, warm hues with a natural, neutral balance and a good deal of nuance and subtlety to shades. Pennywise’s bright red balloons stand out just as intended against the more even handed palette of the general scenery, while the warmth to the protagonists’ sun-kissed skin is spot on, and there’s great detail in their freckles and blemishes.
The motion processing is also superb, with Sony working its trademark magic to sharpen and smooth motion without introducing fizz around edges of complicated patterns, or making everything look overly processed. Our preference here is to use the default Custom mode, rather than Auto, as the latter can come a little unstuck with tricky bits of motion.”
Most UHDTVs can’t reach the full peak brightness mastered into some HDR sources. Without compensation, peaks occurring outside the set’s capability would hard clip, resulting in flat-looking picture highlights. A process called tone mapping is used to avoid this. Metadata in the source material provides information that the set needs to properly tone map the image. For HDR10, this metadata is static: the tone mapping remains the same throughout the runtime, applying the maximum value to the entire program. Dolby Vision, on the other hand, uses dynamic metadata that varies from scene-to-scene. The subjective improvement offered by dynamic metadata is not yet well established and difficult to prove apart from a side-by-side comparison on otherwise identical sets. Nevertheless, many set makers, even those like LG who support Dolby Vision, have developed ways to convert HDR10’s static metadata to dynamic metadata. LG does this through its latest Alpha 9 Gen2 processor. The 65E9 has a Dynamic Tone Mapping control that can be turned off, but I left it on (the default position) for all of my HDR calibrations and HDR viewing.”
