Can "DVI-D out" sometimes provide a video signal to a 15-pin D-Sub VGA CRT via simple connector (or dongle)?

Question

My motherboard (GIGABYTE GA-G41M-ES2H) has 3 video output ports

# 1 x D-Sub port  
# 1 x DVI-D port (Note 3)  
# 1 x HDMI port  

(Note 3) The DVI-D port does not support D-Sub connection by adapter.

Does this mean that in some situations, a DVI-D port can provide a video signal to a D-Sub connector?

I vaguely remember reading something about this, which said it was possible, but without audio.

Is it possible to get a DVI-D to D-Sub connector? ...and if so, why would it not work on this particular motherboard?

Answer 1

D in DVI-D stands for digital. There are DVI-D, DVI-A (analog) and (probably most commonly) DVI-I (integrated, i.e. both).

You need analog (I or A) for the adaptor to work. It doesn't work here, because it's D. They probably provide the note to reduce tech support work load.

Answer 2

No. DVI-I provides both analog and digital signals, but DVI-D only provides the digital signal.
