4K UHD (Ultra HD), also referred to as UHDTV-1 or 4K × 2K, is a display resolution of 3840×2160 pixels (four times as many pixels as FHD) in the same 16:9 aspect ratio.
This resolution is defined in the UHDTV standard as "4K UHD", but prior to the publication of the standard it was sometimes casually referred to as "QFHD" (Quad Full HD).
DisplayPort supports 4K UHD at 30 Hz in version 1.1, and added support for 75 Hz in version 1.2 (2009) and 120 Hz in version 1.3 (2014),[27] while HDMI added support for 4K UHD at 30 Hz in version 1.4 (2009)[28] and 60 Hz in version 2.0 (2013).
When support for 4K at 60 Hz was added in DisplayPort 1.2, no DisplayPort timing controllers (TCONs) existed which were capable of processing the necessary amount of data from a single video stream.
