Hi All,

I have an Anker Prime dock running the Display Link software pushing to 2 external monitors (Viewsonic UX3211 via straight HDMI and Dell U2722D via straight Display Port). The host is a MBP 14" with M4 Pro with Apple Magic KB and Trackpad peripherals. I run this setup with the clamshell closed.

Once the machine goes to sleep, I cannot get the monitors to wake reliably without opening the lid or reseating the cables (I do not have a problem waking the machine when the lid is open, apparently). This setup works flawlessly once I get it up and running again.

I have tried all sorts of OS power settings changes (thanks Google Gemini!) to no avail. Is it the BT peripherals? Is it shoddy HDMI cable? A setting I am missing? Pls halp.
