Hello.
There is a problem about create the second display.
run the command
wmic /namespace:nv path GPU WHERE id=1 CALL fakeEDIDOnPort filePath=C:\ProgramData\EDID.txt output=5 portIndex=1
It will create 4 displays, It seems that the portIndex paramter is not used.
Then, the 4 displays can be removed all by command wmic /namespace:nv path GPU WHERE id=1 CALL fakeEDIDOnPort filePath="" output=5 portIndex=1 , or can be removed one by one by command wmic /namespace:nv path display WHERE id=100x CALL setEDID.
How can I create one display, not 4 displays by fakeEDIDOnPort ?
