Mini DisplayPort is a compact version of the DisplayPort connector introduced by Apple in 2008. Mini DisplayPort is free to license, and in 2009 it was included in the official DisplayPort 1.2 spec. In 2011 Apple and Intel announced the Thunderbolt format, which used the same physical connector, but significantly different protocols.
Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in hertz.. (Hz).
However, when youâre actually playing a game, the displayâs refresh rate does effectively limit the frame rate â if you have an 80hz display and your computer is capable of outputting 120 FPS, your screen will still only be able to show 80 different images per second.
