DisplayPort is the correct answer because it supports higher data rates and resolutions compared to the other display interfaces listed. This makes it capable of handling 4K resolution screens at high refresh rates, which is essential for tasks such as 4K video editing where both clarity and fluid motion are important. While HDMI can also support 4K, the version of HDMI that equals DisplayPort's performance is less common. VGA and DVI do not support high enough resolutions and refresh rates for 4K video editing.
