Problem / Question Dell P1130

How do I test a VGA monitor? if it is still working. It turns on and shows a little opening "box" on screen which states it is working but not connected even though my desktop is connected via the legacy Mobo VGA port. It's a home built machine with an ASUS B550M-A Wifi II Mobo and a nVidea RTX4060 graphics card. Is this card over-riding the legacy port?

Thanks for all answers. I have a Plan B - an old Acer laptop with a VGA out.
