Beat me to it, that was my next question.

I'll take your word for it with the DVI-D I can never remember which version of DVI is which but I know I've encountered onboard graphics with DVI connectors you could plug an adapter into but it wouldn't work and the manual stated as much.

Most graphics cards will have DVI-I out - so there is a digital and analogue signal, and an adapter will work. Most motherboards have both VGA and DVI, so there is no need for an analogue option on the DVI port, and most adapters will not even plug in, as there are extra pins on the DVI-I.

DVI-D = digital
DVI-I = digital or analogue

dual link = supports higher resolutions >1920x1200

I may have another DVI cable - I will try it later today if I can find it.

What do you mean by " You don't have to manually switch the source on the screen? "
Is this a question or a statement?
I have followed the instructions on this MS page: support.microsoft.com

1350421 2013-08-02 05:22:00 Sorry, should have been a question mark there. Some screens will have a button to switch between sources (eg VGA, DVI, HDMI..) like a TV. Most don't but some do.

What you are trying to do should be very trivial - an extremely simple thing that people do all the time, there has to be something not quite up to speed, dodge cable, screen not setup right...bit hard to tell without seeing it.

1350422 2013-08-02 05:23:00 Some monitors require you to use the menu and switch them to the DVI input before they will function, others auto detect and switch themselves.
Some are supposed to auto detect and you still end up doing it manually. Give it a try.

OK now I see what you mean. I did try changing the secondary screen's setting from Auto to DVI, but no result.
I suppose it must be the cable, either that or dodgy onboard graphics but I would not think so with ASUS.
Gotta run now. Will hunt for another DVI cable later. Thanks for the assistance everyone. It is both
reassuring - and %#X!@# - to know that it should be a simple procedure. :dogeye:

1350424 2013-08-02 07:12:00 Have you checked the bios settings Internal Graphics Mode and Surround View, Chapter 3 in the user guide indicates that settings in this area can prevent dual monitor use. jinja_thom (4306)
1350425 2013-08-02 07:19:00 Check in the BIOS as there is probably a setting for which port is active.
Usually something like VGA+DVI or VGA+HDMI so make sure it is set to VGA+DVI.

I could not see anything in the BIOS settings relating to a monitor / display.
If there is a monitor-DVI-VGA-HDMI setting in the BIOS I could see where it would be.

Thought I had a spare DVI cable, but it is a VGA.
The monitor does work OK as I had it on another computer that I was repairing for a friend.
