There is no output from the HDMI connector of my VGA card under BIOS POST / DOS environment. Only one DVI port has signal output. Is this normal?
Due to this VGA card has 2 DVI outputs connected to the primary GPU device, and 1 HDMI output connected to the secondary GPU device. By design, only the primary DVI connector outputs signal under DOS or during POST. The other outputs become available after the Windows display driver loads.
