A technician is setting up a new workstation and needs to connect a monitor that supports 4K resolution at 60Hz. Which of the following video interfaces provides the necessary bandwidth for this requirement?

  1. ADVI-D Single Link
  2. BDisplayPort 1.2
  3. CVGA
  4. DHDMI 1.4
Show answer & explanation

Correct answer: B. DisplayPort 1.2

DisplayPort 1.2 and later versions, along with HDMI 2.0 and later, are designed to support 4K resolution at 60Hz. VGA and DVI-D Single Link lack the necessary bandwidth, and HDMI 1.4 is limited to 4K at 30Hz.

Why the other options are wrong

  • A. DVI-D Single Link has insufficient bandwidth for 4K@60Hz.
  • C. VGA is an analog interface and cannot support 4K resolution.
  • D. HDMI 1.4 supports 4K but only at 30Hz, not 60Hz.

Video Interface Bandwidth

The maximum data transfer rate a video interface can support, determining the highest resolution and refresh rate combinations possible.

  • Higher resolutions and refresh rates require greater bandwidth.
  • Modern interfaces like DisplayPort and HDMI 2.0+ offer high bandwidth.
  • Older interfaces like VGA and DVI have limited capabilities.

Memory trick: For high-res, 'Display' the 'Port' or 'High-Def' the 'Media'.
