How to Set Up KVM and Dual 6MP Display Partitioning on the Barco® MDNC-12130 (Nio Fusion 12MP)
This guide walks you through configuring KVM switching and dual-screen 6MP + 6MP partitioning on the Barco® MDNC-12130 using two workstations equipped with MXRT-6700 graphics cards.
This configuration is ideal for PACS environments where hanging protocols expect two displays, while still taking advantage of a single 12MP diagnostic monitor.
Overview of the Setup
Step 1: Connect Video and USB (KVM Wiring)
Video connections
- PC1 → DP IN 1 on the monitor
- PC2 → DP IN 2 on the monitor
USB upstream connections (required for KVM)
- PC1 → USB UP 1
- PC2 → USB UP 2
Shared peripherals
- Keyboard → monitor USB downstream port
- Mouse → monitor USB downstream port
This enables the display to switch both keyboard and mouse control between workstations.
Step 2: Power On the System
- Turn on the monitor using the rear power switch and set it to “I”.
- Press the jog dial to power on the display.
- Turn on both workstations.
Step 3: Configure EDID for 12MP Operation
To ensure each workstation can drive the display at full resolution over a single DisplayPort cable:
- Open the monitor menu using the jog dial.
- Go to Configuration → Image Sources → Input Settings → EDID format.
- Set EDID format to DisplayID 1.3.
DisplayPort 1
Path: Configuration → Image Sources → Input Settings → DisplayPort 1 → EDID → Resolution
Set to: 12MP
DisplayPort 2
Path: Configuration → Image Sources → Input Settings → DisplayPort 2 → EDID → Resolution
Set to: 12MP
Step 4: Verify DisplayPort Version
Ensure both inputs are configured to use DP 1.2.
DisplayPort 1
Path: Configuration → Image Sources → Input Settings → DisplayPort 1 → Input Interface Standard Version
Set to: DP 1.2
DisplayPort 2
Path: Configuration → Image Sources → Input Settings → DisplayPort 2 → Input Interface Standard Version
Set to: DP 1.2
Step 5: Enable KVM Switching
- Open the monitor OSD menu.
- Go to Configuration → Image Sources → KVM Input Selection.
- Set the option to Enabled.
How to switch between PCs
- Double-press the jog dial.
- The first press opens the shortcut menu.
- The second press switches the KVM input.
Video switches immediately. USB devices may take up to 2 seconds to follow.
Step 6: Configure Display Partitioning (Critical for PACS)
To emulate a dual-monitor environment required by many PACS platforms, split the 12MP display into two 6MP side-by-side displays using Barco® software.
On each workstation
- Right-click on the desktop.
- Open Barco® System Settings.
- Go to Display → Display Partitioning.
- Select a 2-way vertical split (side-by-side).
Once enabled, each workstation sees two independent displays instead of one. This is especially useful for PACS hanging protocols designed for dual-monitor workflows.
Step 7: Verify on Each Workstation
Open Windows Display Settings or Barco® tools and confirm the following:
- Two displays are detected.
- Each display is approximately 2100 × 2800 pixels (6 MP).
- The arrangement is side-by-side.
Important Notes
Resolution and refresh rate
- Each workstation runs at full 4200 × 2800 (12MP).
- In dual-workstation KVM mode, the refresh rate is limited to approximately 45 Hz.
QAWeb recommendation
- Install QAWeb on only one workstation.
- Installing it on both systems may create conflicts when switching between workstations.
Final Configuration Summary
Monitor settings
- EDID format → DisplayID 1.3
- DP1 resolution → 12MP
- DP2 resolution → 12MP
- DP version → 1.2
- KVM → Enabled
Software settings on both PCs
- Open Barco® System Settings
- Go to Display Partitioning
- Select 2-way vertical split (Barco® MXRT series graphics card required for Display Partitioning)
Common Troubleshooting
Keyboard or mouse not switching
Check that both USB upstream cables are connected to the correct monitor ports.
No 12MP resolution available
Confirm that EDID format is set to DisplayID 1.3.
PACS not detecting dual screens
Verify that Display Partitioning has been configured in Barco® System Settings.
One system is not responding to KVM
Check for a missing USB upstream cable or an incorrect upstream port connection.
Conclusion
With this configuration, you can switch seamlessly between two workstations, maintain full 12MP diagnostic display performance, and present the screen as two virtual 6MP displays for PACS compatibility.
This is an effective setup for radiology environments that require both high-resolution imaging and dual-monitor behavior without deploying two separate physical displays.
