For example, displays with HDMI 1.4 ports do not necessarily support the full 340 MHz TMDS clock allowed by HDMI 1.4; they are commonly limited to lower speeds such as 300 MHz (1080p 120 Hz) or even as low as 165 MHz (1080p 60 Hz) at the manufacturer's discretion, but are still considered HDMI 1.4-compliant.
