Ever since I upgraded my MacBook Pro 16 inch to Ventura it hangs intermittently when being used on external monitor in clamshell mode. I have to open the book and hard restart.
The problem becomes more prominent when you let is go to sleep mode. It comes up, goes to login screen and then hangs..
Who else is facing this problem and is there any setting as workaround till the fix?
MacBook Pro 16″, macOS 13.0
I would like to put this up as after multiple trials and errors it turns out that this issue does not occur if your external monitor is connected via HDMI. PS: currently I have disabled "require password" after wake up as well.
Initially my external monitor was connected via DP to USB-C and it changes refresh rates based on sleep and other modes. So it seems Ventura is not able to handle properly the high resolution with changing refresh rates.
Hope this is fixed in some future patch as I would like to use 100Hz monitors.

Thanks for visiting the Apple Support Communities atif.husain,
Based on what you have described as occurring with your external display, we would recommend getting in touch with Apple Support directly. They will have access to tools and resources to ensure your issue is thoroughly investigated. You can get in touch with them here: Get Support.

atif.husain,
Thanks for providing those additional details.
Since that persists while using a DisplayPort to USB-C connection, you'll want to reach out to Apple Support: Contact - Official Apple Support They'd be in the best position to look into this further.
Take care.
