On a new PC (and new monitor) I am seeing a verticle line:

This is on monitor 2, connected to a graphics card (GEFORCE RTX3060) through the one HDMI port (VGA is the only other available port but the video card has no VGA port and on-board graphics vga port shows no signal).  Monitor 1 is connected to the same card via a Displayport port.

Is this an obvious monitor problem?  Note that there is only one merans of connecting Monitor 2.
