hello,

my specs are...

windows 10 from windows download centre
dual core cpu (2007)
amd hd radeon 5450, 512mb, 64bit (2007) (dvi,vga, and hdmi)

when all 3 monitors are connected, only 2 of them will work at the same time. no other video cards are installed. no other drivers are installed. no onboard video driver with my mobo (P5Q Pro) 2007.

i uninstalled the driver and reinstalled, but to no avail.

why is this happening?

thank you.
