I have 2 DVI-I dual link ports on my video card but my monitor has one DVI-D single link one VGA and one HDMI, first question is the single link compatible with with the dual link? it fits right in. 2nd question can i bypass the VGA and use an adapter to run the 2nd DVI-I dual link into the HDMI ?
A dvi-i port has two dvi lanes for very high resolutions and an analog vga output (the four flat pins on the side). The cable you are using defines which one is used. DVI to DVI = DVI, DVI to VGA = VGA. And you can use a DVI-to-HDMI adapter, but will get no sound.
