--- Comment #1 from Alex Deucher <agd5f@yahoo.com> ---
Are you unplugging the cable from the card when you switch the monitors? That
should generate a hotplug event which will trigger the graphics stack to
reprobe the displays. If you are just changing the monitor connected to the
receiver, it sounds like the receiver never sends a hotplug event to the card.
As such the card has no way of knowing that the EDID has changed.
