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).
The issue is calling it 120Hz when it's really just a 60Hz TV with a scanning backlight causing you to see the same frame twice in a row. Another method for potentially reducing motion blur slightly, but increasing the claimed refresh rate a lot, is video processing.ince the one ClearScan 120Hz TV we've reviewed of Toshiba's this year was most definitely a 60Hz LCD, it's, ahem, clear the company is taking liberties in what 120Hz actually means.
