How to Configure System Settings on Your CommBox Meeting Room Display Gen 2

Applies To CommBox Meeting Room Display Gen 2 — All models

Step-by-Step Instructions

Step 1: Open System Settings

• Press MENU on the remote
• Navigate to System Settings and press OK

Step 2: Set the Display Language

• Go to Language Settings
• Select your preferred language and press OK

Step 3: Rotate the Screen (If Needed)

• Go to Rotate Menus
• Choose your orientation: 0° (landscape), 90°, 180°, or 270° (portrait)
• This ensures menus appear correctly when the screen is mounted vertically

Step 4: Adjust Menu Transparency (Optional)

• Go to Menu Transparency
• Adjust the level to make the settings menu easier to read against your content

Step 5: Enable Signal Auto Jump (Optional)

• Go to Signal Auto Jump and toggle it on
• The screen will automatically switch input when it detects a new device

Step 6: Configure HDMI Settings (Optional)

• Go to HDMI Settings to adjust:
• CEC — lets compatible devices control each other (e.g. your laptop can power on the screen)
• EDID modes
• Video range

Step 7: Set Screen Protection

• Go to Screen Protection
• Configure screen refresh or idle behaviour to prevent image retention over long use

💡 Tip: CEC is really useful in meeting rooms — when enabled, turning on your laptop can automatically power on the screen. Check your device's settings to see if it supports HDMI CEC.

Troubleshooting / What to Do If It Doesn't Work

• Menus appear sideways — go to System Settings > Rotate Menus and select the correct orientation
• Screen not auto-switching when a device is plugged in — check that Signal Auto Jump is turned on
