A desktop technician is configuring a workstation to output to a high-resolution display requiring a $3840 \times 2160$ resolution at $60\text{ Hz}$ along with multi-channel digital audio. Which of the following cable types natively support transmitting both the digital video signal at this resolution and embedded multi-channel digital audio over a single cable connection without additional adapters? (Select TWO.)

DisplayPort cableCevap
B
DB-15 VGA cable
HDMI cableCevap
D
Single-Link DVI-D cable

Cevap

The correct options are DisplayPort cable and HDMI cable.

DisplayPort and HDMI are modern digital display standards engineered to carry high-bandwidth digital video signals (such as 4K at 60 Hz) along with embedded multi-channel digital audio over a single cable.

Adım Adım Çözüm

Identify the video resolution and audio requirements.

The scenario requires single-cable transmission for

3840 \times 2160

(4K) at

60\text{ Hz}

along with embedded multi-channel digital audio.

Evaluating cable specifications against resolution, refresh rate, and audio capabilities is necessary to select appropriate interfaces.

Evaluate the capabilities of HDMI and DisplayPort.

Both HDMI (version 2.0+) and DisplayPort (version 1.2+) standards natively support 4K resolution at

60\text{ Hz}

and carry multi-channel digital audio.

These modern digital standards were specifically designed for high bandwidth video and integrated digital audio streams.

Evaluate DVI-D and VGA interfaces.

VGA is an analog video-only standard that cannot carry digital audio. Single-Link DVI-D is limited to

1920 \times 1200

60\text{ Hz}

and standard DVI specifications do not carry audio.

Legacy analog cables and single-link digital interfaces lack the bandwidth and audio features required.
