Applies To: CommBox Classic S5

Step-by-Step Instructions

Step 1: Open the Device Settings menu

Swipe up from the bottom of the CommBox home screen to reveal the Device Settings menu.

Step 2: Go to the “Other” settings tab

Scroll across the top tabs until you find Other. Tap it to view advanced system settings.

Step 3: Find the HDMI EDID setting

Look for a setting labelled one of the following (may vary by firmware version):

• HDMI Version

• EDID Settings

• EDID Mode

💡 Tip: If you're unsure, tap each option under “Other” until you find the EDID option.

Step 4: Choose your EDID mode

You’ll typically see these options:

• Auto – Default mode that lets the screen select the best EDID based on the connected device

• EDID 1.4 – Ideal for older devices that don’t support HDMI 2.0

• EDID 2.0 – Enables full 4K at 60Hz for modern laptops and media players

Tap your preferred option to apply it.

Step 5: Apply and exit

The new setting takes effect immediately. You may need to reboot the screen for the change to fully apply.

💡 Tip: Restart your laptop as well if the screen doesn’t update right away.

Troubleshooting / What to Do If It Doesn’t Work

• No display? Try switching to EDID 1.4 and restart the screen.

• Stuck at 1080p? Change to EDID 2.0 and ensure your HDMI cable supports 4K@60Hz.

• Still flickering or dropping out? Try using another HDMI port or switch to USB-C for better compatibility.

• For ongoing issues, log a ticket on the CommBox Support Portal.
