Pretty much every high end monitor has that issue. It’s a conflict between idle power savings regulations and the hardware needed for 4K 120hz. I just disable “turn display off after x minutes” in windows, set a black screensaver, and leave the monitor and PC fully powered 24 hours a day. This does waste power, but unless reasonable sleep modes that only power off the panel become available that’s what you gotta do.
