KVM switch for dual monitor setup with Mac Mini M2 Sonoma 14.6

I just bought a Mac Mini M2 (2023) and a KVM (like) switch from UGREEN that I saw on this community discussion board.

The Mac Mini can connect to both monitors but can only duplicate, not extend. Under Display settings, it lists only one of the two monitors even though it duplicates to the other, and on the toggle offers only Roku TV, not the other monitor.

It looks like some community members think KVM switches won't work but some have recommended some models that take a little manual manipulation every time, including the "HDMI KVM Switch 2 Monitors 3 Computers EDID Simulation 4K@60Hz 3 Ports KVM Switches Dual Monitor for 3 PC Share 4 USB 3.0 Ports and 2 Screens."

Others have suggested docking stations on Mac Mall and other sites.

The setup is a HP and Acer monitor, and USB Logitech keyboard and mouse. The keyboard and mouse work great, the only thing lacking is the ability to extend the display to the second monitor.

Any help would be greatly appreciated!
