Show answer and explanation
Correct answer: D
Explanation
DisplayPort is the best choice in this scenario because it is designed to handle high-resolution video, including 4K, with superior refresh rates and bandwidth compared to HDMI. Although HDMI could work, DisplayPort provides better performance for high-demand setups, and VGA does not support 4K resolution at all. USB-C is not guaranteed to support video in this case without additional information about its features.
- A. Incorrect.
HDMI can support 4K resolution, but not all HDMI versions support the highest refresh rates. DisplayPort is generally preferred for high resolutions and refresh rates.
- B. Incorrect.
USB-C can transmit video signals when it supports DisplayPort Alternate Mode, but this is not specified in the scenario. It's safer to use a dedicated video port like DisplayPort or HDMI.
- C. Incorrect.
VGA is an older analog standard and does not support 4K resolution. It is unsuitable for this scenario.
- D. Correct.
DisplayPort is specifically designed for high-resolution video and supports 4K resolution with high refresh rates. It is the most suitable option for this scenario.
