Just got the Samsung Neo G9 57” and having an annoying issue. Wondering if any of you are as well.
I have 2x 16 inch MBPs connected to it, an M1 (work) and an M4 (personal). Both have same issue where the monitor refuses to turn on if the MBP lid is closed. I've tried this under PBP, PNP, and just one connected at a time and it's the same results. Basically the only way is to keep the lids open, but that's getting to be annoying since the MacBook Pros are taking up unnecessary space on my desk. Additionally, dragging windows across the desktop is causing them to move from the monitor to the respective MBP display.
I've already enabled "Prevent automatic sleeping on power adapter when the display is off" but it did nothing.
I've tried both with the supplied Samsung cables and with the Cable Matters cables/adapters, again same result.
Anyone experience something similar?
