Hello!

My monitor cable has VGA connector, but video card has only DVI. So I bought an adapter (I guess that's what it is called). It looks like this:

When I connect monitor and video card, I get "Check Signal Cable".

The cable of the monitor is fine, because it works when connected to internal graphics card. So I guess the adapter is making problems. It is a DVI-A to VGA adapter. The monitor is analog (Samsung SyncMaster 940nw). Is the adapter the right one, or maybe I need DVI-D to VGA or DVI-I to VGA?

And the video card is working all right, I connected it some time ago to another computer without problems (to a monitor which supports analog and also digital signal, and with a DVI cable).

The adapter must match the DVI spec of the graphics/video card. This can be determined by examining the layout of the pins on the DVI connector on the card.
DVI-A only supports an analog signal, but since the the card is putting out a digital signal nothing is getting to the monitor.

The card will either be DVI-I or DVI-D as here: http://www.lindy.co....s/DVIGuide.html

I checked the pins on both video card connector and the adapter, and they are the same after all: both DVI-I Dual link.
So everything should work.

Tomorrow I will try uninstalling the driver for internal graphics and disabling internal adapter (or whatever it's called) through device manager.

Thanks for help, anyway. :D
