MacBook Pro M2/M3 Pro – Internal Display Goes Black

I’ve observed the same problem on multiple MacBook Pro devices in my office (both M2 Pro and M3 Pro models) — at least 4 devices so far. This makes it seem like a broader issue rather than a one-off hardware defect.

See my other reply to physina. We have thousands of Macs in use on Sequoia in a large facility and most are used with large external displays, and I have never seen this issue in our labs. That tells me that the multiple Macs in your office with this symptom are configured similarly and may share an installed item that is conflicting with the OS. The other user, physina, mentioned using Avast ... do you have any security tools, network monitors, anti-virus, cleaning apps, VPN, anything like those things installed or running?

That is weird, are your display settings set up correctly ?

If so, have you tried to boot the Mac in the safe mode to see if the issues persist? If they dont persist in the safe mode they are caused by an external piece of software I am afraid

1. On your Mac, choose Apple menu  > Shut Down.
2. Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
3. Press and hold the power button on your Mac until “Loading startup options” appears.
4. Select a volume.
5. Press and hold the Shift key, then click Continue in Safe Mode.
6. The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

Avast is known to be invasive and sometimes interfere with the MacOS. You should obtain its uninstaller and completely uninstall it (not just turn it off).

If you or the OP have other similar "tools" installed, they should be removed. We have over 3,000 Mac laptops in operation at work, almost all are used with external monitors, all are on Sequoia, and I have never seen this issue appear there, nor have I seen it on my home Mac laptops.

MacAir M3 15" Sequoia 15.6 24 GB RAM - If I close my laptop and open it back up, the display returns. Turned off my screen saver but it did not resolve. Began within a few hours after OS upgrade. Avast scan was clear x 2.

Facing the same issue in my M3 Pro. The Mac display goes black, and nothing is visible, but the secondary display is working fine.

My MacAir M3 15" Sequoia 15.6 24 GB RAM is also blacking out - started last night - so far about a dozen incidences. No new software added in weeks.
