Monitor inputs, physical units and reference modes

Physical outputs, rendering engines, exact models and observed requirements are separate evidence.

The useful distinction

Read the model suffix, labeled output and exact monitor input.

Claim inspection dates: 2026-10-03 · Independent review pending

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

A second input is not a second physical display. [C158A]

PA279CV lists a 3840 by 2160 panel, maximum 60 Hz, and distinct HDMI, DisplayPort and USB-C video inputs. [C158B]

Bounded facts, visible unknowns

Specifications and limits

Monitor inputs, physical units and reference modes facts and limitations
Workflow boundaryOne host, one dock, direct independent display paths only. [C158A] [C158B]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

Two identical monitors can be units 1 and 2. Selecting two inputs on unit 1 means the same monitor, and the full-screen allocation model flags the duplication. PBP and PIP are not modeled.

Before you connect

What to check

  1. Identify host, dock and monitor models.
  2. Keep native, software and shared-resource findings separate.
  3. Record the unknowns before preparing a report.

Panel mode is reference evidence

A panel resolution and refresh rate do not establish the exact timing accepted on every input. The result separates panel reference, dock-table coverage and cable evidence.

Keep conversion directional

Matching connector families does not validate a cable. Different families require exact directional cable or converter documentation; this release does not synthesize an adapter product.

Your next step
