How to Set Up KVM and Dual 6MP Display Partitioning on the Barco MDNC-12130 (Nio Fusion 12MP)

This guide walks you step-by-step through configuring the KVM functionality and dual-screen (6MP + 6MP) partitioning on the Barco MDNC-12130 using two workstations with MXRT-6700 graphics cards.

This setup is commonly used in PACS environments where hanging protocols require two displays, while still leveraging a single 12MP panel.

Overview of the Setup

You will configure:

• Two workstations connected to one display

• KVM switching (keyboard/mouse shared between systems)

• Full 12MP signal per workstation (via single DP cable each)

• Display partitioning into two 6MP virtual monitors (side-by-side)

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

Note: USB UP 2 may have a protective cap—remove it before connecting.

Shared peripherals:

• Keyboard → monitor USB downstream port

• Mouse → monitor USB downstream port

This allows the monitor to switch your keyboard and mouse between both systems.

Step 2: Power On the System

1. Turn on the monitor (rear power switch to “I”)

2. Press the jog dial to power the display

3. Turn on both workstations

Step 3: Configure EDID for 12MP Operation

To ensure each workstation can drive full resolution over a single DP cable:

1. Open the monitor menu using the jog dial

2. Go to Configuration → Image Sources → Input Settings → EDID format

3. Set EDID format to DisplayID 1.3

Then configure each input:

For DisplayPort 1:
Go to Configuration → Image Sources → Input Settings → DisplayPort 1 → EDID → Resolution
Set to 12MP

For DisplayPort 2:
Go to Configuration → Image Sources → Input Settings → DisplayPort 2 → EDID → Resolution
Set to 12MP

Step 4: Verify DisplayPort Version

Ensure both inputs are using DP 1.2:

For DisplayPort 1:
Configuration → Image Sources → Input Settings → DisplayPort 1 → Input Interface Standard Version
Set to DP 1.2

For DisplayPort 2:
Configuration → Image Sources → Input Settings → DisplayPort 2 → Input Interface Standard Version
Set to DP 1.2

Step 5: Enable KVM Switching

1. Open the monitor OSD menu

2. Go to Configuration → Image Sources → KVM Input Selection

3. Set to Enabled

How to switch between PCs:

• Double-press the jog dial
  First press opens the shortcut menu
  Second press switches the KVM input

Video switches instantly. USB devices may take up to 2 seconds to follow.

Step 6: Configure Display Partitioning (Critical for PACS)

To emulate a dual-monitor setup required by many PACS systems, split the display into two 6MP displays using Barco software.

On each workstation:

1. Right-click on the desktop

2. Open Barco System Settings

3. Go to Display → Display Partitioning

4. Select a 2-way vertical split (side-by-side)

This creates:

• Left display → 6MP

• Right display → 6MP

Result:

Each workstation now sees two independent displays instead of one. This allows PACS hanging protocols that require dual monitors to function correctly.

Step 7: Verify on Each Workstation

Open Windows Display Settings or Barco tools and confirm:

• Two displays are detected

• Each display is approximately 2100 × 2800 (6MP)

• Arrangement is side-by-side

Important Notes

Resolution and refresh rate:

• Each workstation runs full 4200 × 2800 (12MP) (split into two 6MP side by side using Barco Display Partition). Barco MXRT graphics card is required for Display Partitioner to function.

• In dual-workstation KVM mode, refresh rate is limited to approximately 45 Hz

QAWeb recommendation:

• Install QAWeb on only one workstation

• Installing on both PCs will cause conflicts with calibration and image quality when switching between systems

Final Configuration Summary

PC1:

• DP → DP IN 1

• USB → USB UP 1

PC2:

• DP → DP IN 2

• USB → USB UP 2

Monitor settings:

• EDID format → DisplayID 1.3

• DP1 resolution → 12MP

• DP2 resolution → 12MP

• DP version → 1.2

• KVM → Enabled

Software (both PCs):

• Barco System Settings → Display Partitioning → 2-way vertical split

Common Troubleshooting

Keyboard or mouse not switching:

• Check USB upstream cables are connected correctly

No 12MP resolution available:

• Ensure EDID is set to DisplayID 1.3

PACS not detecting dual screens:

• Display partitioning not configured

One system is not responding to KVM:

• USB cable missing or connected to the wrong upstream port

Conclusion

With this setup, you get seamless switching between two workstations, full 12MP diagnostic performance, and dual 6MP virtual displays for PACS compatibility.

This is the ideal configuration for radiology workflows that require both high resolution and dual-monitor behavior without the need for two physical displays.
