Lenovo M910Q DisplayPort to HDMI Black Screen Issue – Intel HD 630

[Rahul Saha]

---

My System Specs (Lenovo ThinkCentre M910Q Tiny):

• CPU: Intel Core i5 7th Gen (i5-7500T)

• RAM: 16 GB DDR4

• Storage: 256 GB SSD (SATA or NVMe)

• Graphics: Intel HD Graphics 630 (Integrated)

• Ports: 2x DisplayPort++ and 1x VGA

---

Current Setup:

• I'm currently running macOS Sequoia 15.5 (latest version) on this system.

• I will share the EFI folder link below for troubleshooting help.

---

My Issues:

1. I'm using a DP to HDMI adapter (likely passive), since my monitor doesn't have a DisplayPort input.

   • VGA port works, but the display quality is poor.

   • DP to HDMI shows a black screen, no display output.

2. I'm facing a macOS sleep/wake issue – the system either doesn't wake up or shows glitches after waking.

3. I want to use both DP ports for a dual-monitor setup under macOS, but I'm unsure how to configure this properly.

---

What I Need Help With:

• Should I switch to an active DP to HDMI adapter?

• How can I fix the macOS sleep/wake issue?

• How to enable and use both DisplayPorts in macOS?

• Please review my EFI folder (link will be shared) and guide me with beginner-friendly steps.
