The leap enthusiasts have been waiting for

Luminance in the real world
 Sunlight = 1,600,000,000 nits
 Fluorescent light = 10,000 nits
 Highlights = 1,000 to 10,000 nits
 White Range = 250 to 1,000 nits
 Most typical objects = 1 to 250 nits
 Shadow details = 0.01 to 1 nit
 Ultra Blacks = 0 to 0.01 nit
 Most Current PC displays = 0.1 to 250 nits max
 Excellent Current LCD HDTVs = 0.1 to 350-400 nits max
 HDR UHDTVs = new CE industry standard
 0.005 to 10,000 cd/m2 = Nits
 HDR LCDs w LED local dimming
= peak 1K today going to 2K nits holiday ‘16
 HDR OLEDs
= peak 500 today to 1K nits holiday ‘16 with absolute blacks
AKA “nit,” A unit of measurement of
luminous intensity approximately
equivalent to one candle

We Need Better Encoding
 An electro-optical transfer function (EOTF) defines how
to encode a digital signal for reproduction as visible light
 The Barten ramp is the best known model for replicating
the human vision system’s sensitivity to brightness
 Today’s consumer content is designed around
Rec.1886 EOTF
‒ Designed in 1930s for CRTs
‒ Only considers up to 100 nits of brightness
‒ Wastes encoding bits and crushes black levels
 10-bit ST 2084 is for HDR
‒ Modeled around modern LCD capabilities
‒ Consistent encoding 0-10,000 nits
‒ Dramatically improves detail/efficiency in black levels
 12-bit ST 2084 even better, exceeds human visual acuity

Early attempts at PC HDR
 Many game engines render in high dynamic range
 High Dynamic Range Rendering (HDRR) results are
internally mapped back to SDR for output to a
gamma 2.2 display
 Overexposure or blown out colors are common
 First: we need better tonemapping algorithms
 Second: we need to tonemap for an HDR display
Many game engines internally use High Dynamic
Range Rendering to preserve high- and lowlightsHDRR

technology-enabled display
 Adaptive algorithm automatically adjusts GPU output and refresh rate to gracefully prevent juddering from
sudden drops in framerate
 Automatically enabled on all AMD FreeSync™-ready monitors where max refresh is ≥2.5X min. refresh
 No user configuration or proprietary monitor hardware required

More on Low Framerate Compensation (LFC)
 LFC algorithm monitors render rates and adaptively
inserts additional frames to enforce smoothness
 Asus MG279Q is a 35-90Hz AMD FreeSync™
enabled monitor (maximum ≥ 2.5x minimum)
 No LFC: 35 FPS is the DRR limit for this display,
judder possible as VSync takes over < 35 FPS
 With LFC: AMD FreeSync™ remains active < 30 FPS,
smoothing out undesirable VSync judder
 LFC is tunable in software and can be adjusted to
meet the needs of new displays
 Again: no proprietary module required
