U3415W, MacBook Pro M1, intermittent blackout
Dell U3415W
Hi there,
I have connected my MacBook Pro M1 to my U3415W using HDMI. The video and audio are fine, but about every half hour or so the screen blacks out for a second before coming back on again.
I have MacBook Pro M1, 16GB RAM, OS Ventura.
Many thanks

Connect and test the monitor with a different computer. If the blackout is resolved, the issue is with the macbook. If the blackout is persisted, test with a better quality cable.

Is the monitor's On-Screen Display (OSD) set to "Mac"? See Setup Guide.
