Comment # 1 on bug 71083 from 
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.
