Worked out from Pixel density: ppi = sqrt(width_px^2 + height_px^2) / diagonal_inches and 1 other source.

How this is worked out

4 steps
  1. Diagonal in pixels = sqrt(1920^2 + 1080^2) = 2202.9072 px
  2. Pixel density = 2202.9072 / 24 in = 91.7878 ppi
  3. Panel measures 20.918 x 11.766 inches (16:9)
  4. Dot pitch = 25.4 / 91.788 = 0.2767 mm
