Difficulty: Very hardDisplay Cables and Connectors

Match each display cable standard or connector configuration to its correct architectural specification and technical capability.

  • DVI-I Dual-LinkCarries both dual-channel digital video signals and integrated analog VGA pins, supporting legacy passive DVI-to-VGA adapters.
  • DisplayPort 1.4Natively supports Multi-Stream Transport (MST) to daisy-chain multiple independent display monitors over a single physical output.
  • HDMI 2.1Replaces traditional TMDS signaling with Fixed Rate Link (FRL) to achieve up to 48 Gbps bandwidth for uncompressed 8K resolution.
  • Thunderbolt 3Provides up to 40 Gbps throughput over a USB Type-C physical connector by multiplexing PCIe and DisplayPort protocol traffic.

Answer

DVI-I Dual-Link matches with the ability to carry dual-channel digital and analog VGA signals. DisplayPort 1.4 matches with native Multi-Stream Transport (MST) daisy-chaining support. HDMI 2.1 matches with Fixed Rate Link (FRL) signaling up to 48 Gbps. Thunderbolt 3 matches with 40 Gbps PCIe and DisplayPort protocol tunneling over USB Type-C.
Each display standard utilizes distinct physical pinouts and signaling protocols tailored to specific use cases: DVI-I integrates analog pins for legacy VGA backward compatibility; DisplayPort natively supports packet-based Multi-Stream Transport (MST) for display daisy-chaining; HDMI 2.1 introduces Fixed Rate Link (FRL) encoding to handle up to 48 Gbps throughput; and Thunderbolt 3 utilizes USB Type-C hardware to tunnel PCIe and DisplayPort signals at up to 40 Gbps.

Step-by-Step Solution

1
Analyze DVI connector variants.
Identify that 'I' in DVI-I stands for Integrated (analog + digital), distinguishing it from DVI-D (digital only) and enabling passive conversion to analog VGA.
DVI-I incorporates four additional pins around the flat blade specifically designated for analog RGB signaling.
2
Evaluate DisplayPort feature sets.
Match DisplayPort 1.4 with Multi-Stream Transport (MST) daisy-chaining.
DisplayPort standard natively supports packetized video streams allowing MST topologies across compatible monitors.
3
Examine HDMI 2.1 signaling improvements.
Link HDMI 2.1 to Fixed Rate Link (FRL) technology.
To achieve 48 Gbps bandwidth for high resolution/refresh rates (such as 4K at 120Hz or 8K at 60Hz), HDMI 2.1 transitions from TMDS to FRL.
4
Assess Thunderbolt 3 protocol requirements.
Associate Thunderbolt 3 with 40 Gbps throughput over USB Type-C physical connectors.
Thunderbolt 3 leverages the Type-C form factor while encapsulating PCIe data and DisplayPort video packets at speeds up to 40 Gbps.
