When a Barco DI monitor starts up or restarts and shows a black screen, it's common to suspect a hardware or power supply issue. However, before jumping to conclusions, please check the monitor’s power mode before shutdown.
❓ Key Question
Was the monitor in Standby or SoftOff mode before it was powered off or lost power?
🔍 Understanding Power Modes
| Mode | Wake-Up Method | LED Behavior | Backlight | Power State |
|---|---|---|---|---|
| Standby | Mouse or keyboard | Slow flashing orange | ON (min level) | Fully powered |
| Suspended | — | Rapid flashing orange | OFF | Fully powered |
| Hibernate | Mouse or keyboard | Solid orange (no flash) | OFF | Partially off |
| SoftOff | JogDial or OSD Softkey only | Solid orange (no flash) | OFF | Inputs deactivated |
🛠️ Solution
If the monitor was placed in SoftOff mode using the JogDial or OSD Softkey, it cannot be woken up by a power cycle or keyboard/mouse input.
To wake it up:
1. Locate the JogDial or OSD Softkey (see images below).
2. Press the same button again to bring the monitor out of SoftOff.
3. The monitor should now display video and be recognized by Windows.
💡 Note: This behavior is by design to prevent image retention and is not a hardware defect.
📌 Why This Happens
Barco DI monitors are designed to retain their last known power state (such as Standby or SoftOff) even after a power cycle or outage. This behavior is intentional and aligned with industry standards for medical-grade displays.
Here’s why:
-
Preservation of Display Integrity:
Medical displays are susceptible to image retention or burn-in if static images are shown for prolonged periods. By staying in SoftOff or Standby after a power event, the monitor avoids unintentionally displaying static content when not in active use. -
User-Controlled Wake-Up:
SoftOff mode ensures that the monitor only powers up when explicitly instructed by the user (via JogDial or OSD Softkey). This prevents accidental wake-ups during system reboots or power fluctuations. -
Compliance with Medical Safety Standards:
In clinical environments, predictable and controlled behavior is critical. Automatically powering on after a power loss could lead to unintended image display or confusion during diagnostic procedures. -
Not a Hardware Fault:
This is not a malfunction or defect. It’s a safeguard built into the monitor’s firmware to support long-term reliability and image quality.
