It used same technology of many specific illumination "zones" as many today's HDR monitors (no wonder, this BrightSide firm said they patented it and sold to various display manufacturers.) Still, it was connected via DVI , not sure at that bit depth and colorspace ... PS: I played around with Colorspace property on my hdmi connector on RX550 via xrandr: guest@slax:~/botva/src/src$ DISPLAY=":0" xrandr --output 0x54 --set Colorspace Default guest@slax:~/botva/src/src$ DISPLAY=":0" xrandr --output 0x54 --set Colorspace BT2020_YCC guest@slax:~/botva/src/src$ DISPLAY=":0" xrandr --output 0x54 --set Colorspace Default guest@slax:~/botva/src/src$ DISPLAY=":0" xrandr --output 0x54 --set Colorspace opRGB guest@slax:~/botva/src/src$ DISPLAY=":0" xrandr --output 0x54 --set Colorspace Default Anything but Default resulted in VERY pink (nearly red!) image. Not sure if this is limitation of 8bit per channel mode or hdmi to vga adapter I use? opRGB = Adobe RGB as far as I can see in Wiki. > > more recent 2020 paper > > > https://www.cambridge.org/core/services/aop-cambridge-core/content/view/3E58E1A14BC6543EB47B6C3B1A172C96/S2048770320000050a.pdf/fully-automatic-inverse-tone-mapping-algorithm-based-on-dynamic-mid-level-tone-mapping.pdf > > >
