My Samsung monitor's screen frequently goes black or snowy, then returns to what I am working on. Connections are tight. I'm running a Mac mini, M1 chipset, purchased in 2020. Refresh rate set at 60 Hertz. Monitor set to 3840 x 2160, 134.8 kHz, 60 Hz.

Mac mini (M1, 2020)
Yeah' the Mac mini has issues with long HDMI cables that are made for PlayStation's, X-Box's and TV boxes.
Another option instead of testing a shorter Premium Certified HDMI cable, is to get and use a USB-C to DisplayPort 1.4 8K cable with that Samsung WideScreen.

Any HDMI cable over 3 feet is inviting trouble in the long run. Use 3 or shorter, should fix.
What model number is the Samsung?
What cable or adapter & cable are you using?
It's a Samsung Model U28E590D with a PowerBear 4K HDMI 10' cable. No adapter.
