SB220Q Randomly turns on and off

I have 2 monitors on a docking station: one an Acer HA220QQ, the other an ACER SB220Q.

The HA 220Q has no problem. THE SB220Q does randomly, since being connected to the docking station, randomly turns on and off for a second or 2. Tried making it the primary display, happens occasionally. Tried making it secondary display, same thing.

Windows 11 is the OS.

Made sure the resolution and refresh rate are the same. Doesn't seem to matter. (1920x1080, 60Hz) also happens at 1920x1080 50Hz.

HA220Q is HDMI, SB220Q has HDMI to displayport adapter; happens even if I switch those around or have both as displayport (my dock only has one HDMI, and 2 displayport jacks)

HA220Q is a workhorse, had it since 2019; SB220Q is new-er (a couple of years old).

I'm at my wits end.

Thanks in advance for any ideas.
