DECEMBER 2019 PCWorld 103Definitions: bpp is bits per pixel. 24bpp/3 subpixels = 8-bit color; 30bpp/3 = 10-bit color. 4:4:4 means
full color and luminance data is being delivered. 60Hz and 60fps are equivalent. HDMI supports a second
video stream, which can be used for a second display or for picture-in-picture/picture-by-picture, but it’s
rarely implemented. The DisplayPort cable spec allows for power transmission on pin 20, but these days,
only Thunderbolt 1 and 2 support power carriage.
