Apple’s Worldwide Developers Conference to kick off June 10 at 10 a.m. PDT with Keynote address

The Keynote will be available to stream on apple.com, the Apple Developer app, the Apple TV app, and the Apple YouTube channel. On-demand playback will be available after the conclusion of the stream.

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

Replaced a dell external monitor with a new studio display today. After connecting to my iMac (2017) it now will not turn on. I can play music on it, but need the picture. Help

Hello!

From Set up and use Apple Studio Display - Apple Support, you need to be using macOS Monterey 12.3 or later. Is your Mac running this or a later version? If not, try to update your Mac: Update macOS on Mac - Apple Support.

If the issue persists, I recommend you try in Safe Mode. Safe mode can help you to determine whether an issue is caused by software that loads as your Mac starts up: How to use safe mode on your Mac - Apple Support.

You can also try in a separate, "test" user account on your Mac: Add a user or group on Mac - Apple Support.
