[QUOTE="howardc64, post: 1934393, member: 381897"] Here is a detail macOS event analysis with this issue. It can be argued its a macOS problem and/or Samsung monitor problem. But they are basically not cooperating. Samsung monitor is cycling USB-C charging which wakes up macOS (darkwake) and this kicks off the monitor screen wake, no USB-C video signal, monitor to standby and repeat... [URL='https://discussions.apple.com/thread/253484358']MacBook Pro M1 wakes due to USB-C chargin… - Apple Community[/URL] PCs works properly with Samsung USB-C monitors. macOS works properly with DELL USB-C monitors. So either Samsung firmware and/or Apple macOS updates to properly coordinate. Meanwhile, only work around is to turn monitor off when macOS goes to sleep. Not quite so user friendly (multiple buttons and multiple presses to turn off) [/QUOTE]
