Nee, jak jsem psal, barevná hloubka výstupu může být 6/8/10/16 bitů - jakákoli z nich.

In the case of digital displays, the 10-bit data goes through a spatial and temporal dithering process for 8-bit or 6-bit displays (most modern desktop LCD panels are 8-bit, while many notebook panels remain at 6-bit), however newer 10-bit and 16-bit panels can be driven directly from the Avivo digital display outputs - in the case of 10-bit panels it is kept in the same format as was in the display pipeline, and is outputted as is, and with 16-bit displays the colour depth is up-scaled, although it will remain at the 10-bit processing level.
