Have noticed that most new video cards now come only with DVI connectors.
If lucky, there will be an adapter in the box to convert the DVI connector
back to the older VGA 15-pin DSub connector.
This is fine. And, yes, I do understand that video cards may now come with
HDMI connections also.
So, I now have these 3 DVI-VGA adapters. One from an old Gainward card of
~2000, one from an eVga FX5500 of 2004, and now one from a new MSI R4670 of
2008. I am confused about these adapters. 2 (the GW and the MSI) are the
same. The eVga adapter is different. It is the number of pins on the DVI
side ... !!!
(MSI adapter) L->R
What I call the DVI locator; 2 top, wide blade middle, 2 bottom.
3 top, 3 middle, 2 bottom, 1 missing from this block of 9.
3 top missing, 3 middle missing, 3 bottom missing.
2 top, 2 middle missing, 2 bottom.
(GW adapter) L->R
What I call the DVI locator; 2 top, wide blade middle, 2 bottom.
block of 9 pins; 3 top, 3 middle, 2 bottom w/1missing pin (lower right)
blank space in middle (perhaps 6 pins worth)
block of 9 pins; 1 missing and 2 pins top, 3 pins missing middle, 1 missing
and 2 pins bottom.
(The eVga adapter) L->R
What I call the DVI locator; 2 top, wide blade middle, 2 bottom.
full array of 24 pins; 8 top, 8 middle, and 8 bottom.
I really wish to hope all 3 adapters are compatible? I searched the web
but have not found much info about these adapters except some odd warnings
of incompatibilities. I'll accept that conversion of the DVI connector to
the 15-pin DSub VGA connector may affect video quality.
Any information, links, opinions are welcome. I have not ever used a DVI
based video cable yet. I have never even seen one!
Thank you,
Duncan
