Recently purchased the MPG 346CQRF X24 and have had trouble with the monitor sleeping. When the PC sleeps it will make an attempt to sleep, flickering on and off as it attempts to find an available display, but then it will settle on a black screen; not off, just fully black. Attempting to wake the monitor will usually work, but on occasion it will further not wake up nor display OSD until the monitor is power cycled.
Currently using default Balanced power plan with 5 minutes to monitor sleep and computer to sleep never. OSD settings are default aside from the rear RGB LED being disabled. HDR and auto HDR are enabled in Windows. Also using a second monitor which standalone experiences none of the issues, have attempted powering this monitor off and removing display from it also which has not helped. Have updated both graphics and monitor drivers. Problem presented day 1 last week with a near-fresh Windows 11 install.
Can provide more information if need be, anything helps.
 
1.Please modify Auto Scan to OFF in input source page under OSD menu.

2.Please modify Power Button to Standby in settings page under OSD menu.

It is manual for MPG-346CQRF-X24 on MSI website.
