Phone Connected to Espresso Display Causes Screen to Turn Off and OnUpdated 8 months ago

Issue: Screen Turns Off and On When Phone is Connected to Espresso Display

If your Espresso Display screen keeps turning off and on while connected to your phone, the most likely cause is insufficient power. When a phone is connected to an external display, particularly for extended use or demanding tasks, it may not provide enough power to keep the connection stable. This leads to the screen on the Espresso Display turning off and on intermittently.

Main Cause: Phone Needs External Power

Phones have limited power capacity, and connecting them to an external display like the Espresso Display can quickly drain their battery. When the phone’s power supply runs low, it can struggle to maintain a stable video connection to the display, causing the screen to flicker or turn off and on repeatedly.

Solution: Charge Your Phone While Using the Espresso Display

To prevent the screen from turning off and on, you need to charge your phone while it's connected to the Espresso Display. This will ensure that your phone has enough power to sustain the video connection without interruptions.

Steps to Resolve the Issue:

1. Connect Your Phone to a Power Source:

   • Use a charger to plug your phone into a power outlet while it’s connected to the Espresso Display.
   • If you’re using a USB-C hub or adapter, make sure it supports power passthrough, allowing you to charge your phone and use the display at the same time.

2. Monitor Your Phone's Battery Level:

   • Keep an eye on your phone's battery level. If it’s low, the phone might prioritize its own power needs over the external display, leading to connection drops.

3. Use a Compatible USB-C Hub:

   • Ensure you're using a USB-C hub or adapter that supports both video output and power delivery. This will allow you to charge your phone while maintaining a steady connection with the Espresso Display.

Troubleshooting If the Issue Persists

If the issue continues even after charging your phone, try the following:

• Use a High-Quality USB-C Cable: Make sure your USB-C cable supports both video output and power delivery. A low-quality or incompatible cable might not provide enough power to keep the display running smoothly.
• Check Your Phone’s Compatibility: Some phones may have limitations when it comes to powering an external display. Ensure that your phone supports video output while charging simultaneously.
• Reboot Your Phone and Display: Sometimes, a simple restart of your phone and the Espresso Display can resolve temporary connection issues.
