Losing my mind over a docking station problem – Monitor not receiving input

Resolving Monitor Connectivity Issues with a Docking Station: A Step-by-Step Troubleshooting Guide

Introduction

Docking stations are invaluable tools for enhancing productivity, offering seamless connectivity for peripherals and multiple displays. However, encountering issues such as a monitor not receiving input can be frustrating, especially when hardware configurations change. This article explores common troubleshooting strategies and solutions to resolve monitor input problems when using a docking station, drawing from real-world scenarios.

Scenario Overview

Consider a professional transitioning to a new laptop model—specifically, an HP Omnibook 7 running Windows 11—paired with a legacy Lenovo ThinkPad DK1633 docking station previously used with an HP EliteBook x360. While most peripherals (keyboard, mouse, webcam, Ethernet) function correctly, the external monitor connected via the docking station intermittently fails to display input.

Initial Observations and Symptoms

The monitor is connected through the docking station using Direct Input (the sole input channel available).
The monitor displayed output successfully for approximately a day, including overnight.
After the laptop entered sleep mode, the monitor ceased to receive input.
Other connected peripherals continue functioning flawlessly.
The laptop remains charging via the dock, albeit at a slower speed.
The issue reoccurred despite prior successful operation and has persisted despite multiple restarts and resets.

Troubleshooting Steps Undertaken

Driver and Firmware Updates
Verified and installed the latest Windows 11 updates.
Downloaded and installed the latest DisplayLink drivers and DisplayLink Manager software.
Updated monitor drivers where applicable.
Checked for BIOS updates and relevant firmware updates for the laptop and docking station.
Hardware and Connection Checks
Reconnected all cables, ensuring secure connections.
Attempted alternative cables to rule out faulty wiring.
Tried a second docking station of the same model to rule out hardware defects.
Reset and Power Cycles
Restarted the laptop, docking station, and monitor multiple times.
Performed a complete reset of the docking station by unplugging and performing power button resets.
Verified that power delivery is active, though at a reduced rate.
BIOS and Configuration Settings
Explored BIOS options related to USB-C, Thunderbolt, and display output configurations.
Did not find any relevant settings impeding display connectivity.
