Dual monitor help! (paying if solved)

[Huggies]

Hello, for the past 2 days I've been trying to connect my PC to my 2 identical monitors for expanded viewing.

A little about whats the problem:
So basically both my monitors are VGA ports at the back, my computer has a DVI-I, VGA and HDMI port. I have tried connecting a VGA splitter which just mirrors the displays, so atleast we know both monitors work. I've than bought a DVI-I to VGA adapter in hope that the transition will work? Still no luck. I than tried plugging in HDMI and VGA and it works perfect aswell.

When the DVI-I port is plugged with the adapter to my monitor all that happens is, its changed from "Connect a lead" to "No signal" and the blue on light turns to a amber sleep light.

What possibly could be the problem?

The graphics card is a: ATI Radeon 4560 - I think? should be that version


If anyone could possibly help me sort the problem out, I'll happily donate via paypal for your time!

Thanks, Rhys.

Have you set it to dual monitors in the preferences panel, by default it mirrors.

[lawrawrrr]

Mine does this all the time - my DVI monitor I just have to reset it, take the cable out and put it back in before it will turn on an extend the displays. I thought it was just my monitor though, maybe its a general thing?

Windows doesn't even detect the 2nd monitor? :/

I actually don't have a DVI monitor, just 2 VGA monitors. I've connected a DVI to VGA adapter to my pc so I can use the VGA port in my monitor

Could be a dodgy DVI -> VGA adaptor.

Either that or the DVI port on your graphics card.

You said you tried plugging in a different screen via DVI and one of the VGA monitors and that worked?

Im using only PCI graphics card, not onboard default ones. The ports on the graphics card are; HDMI, DVI-I and VGA

[Jack!]

You cannot use DVI and HDMI at the same time, has to be either DVI/VGA or HDMI/VGA, The card has one digital signal and one analog.

This information is incorrect.

Also partly incorrect; a switch would not allow for desktop extension with multiple monitors.

Its not incorrect? Only did some quick reaserch on the card buts its only capable of outputting one digital signal at once?

Whether or not this is true (I can't find any information on it), when using a DVI -> VGA adaptor, the DVI signal is using DVI-A, the analog version of DVI, since you can't convert DVI-D to VGA like that.
