gigabyte B75M-D3H motherboard supports dvi and hdmi at the same time - dual monitors?

[vikasg]

Hello, B75M-D3H has VGA/DVI/hdmi output. Do you know that hdmi and dvi are supported at the same time for a dual monitor setup?
Monitor 1: dvi + vga
Monitor 2: hdmi + vga
Monitor 2 never shows any display when connected thru hdmi cable but it works fine thru vga.

Integrated Graphics Processor:
1 x D-Sub port
1 x DVI-D port, supporting a maximum resolution of 1920x1200
* The DVI-D port does not support D-Sub connection by adapter.
1 x HDMI port, supporting a maximum resolution of 1920x1200

How do I tell if motherboard is sending data on hdmi at all? Or is there a problem with my monitor?

I have an older motherboard with integrated graphics (HD4300 or some such) with D-sub, dvi, and hdmi. The manual specifically stated that you could not use the dvi and hdmi at the same time, although you could use either with the D-sub. My guess is that it can only generate 1 digital output and you have to decide which port to send it through. I think it might have been a bios setting.
To check if your hdmi is working, unplug monitor 1. Might need to re-boot.
