i just put external graphics card on my computer.
my monitor cable is connected in the built in graphics card because when i put in the external nothing will appear.
i know i need to install the drivers of the external graphics card but i dont know what's my external graphic card is..
and when i look at the device manager it just sees the built in. and i still dont know what driver i should install for the external graphics card to work
 
get the card out, there should be some writing (usually in white) to indicate the model. depending on how old that is, the current driver should work fine, as the driver has been unified (one driver for all) years ago. save those very very old gpu's

there is no writing of the graphics' card name in it.
i use nvidia scanner and it just still sees the built in, i just need to know the name of my external video card so i can install its drivers :(
