Hi all.  I've just bought a new pre-built rig with a Radeom HD 7870 card.  It's all running fine, except I can't get my second monitor to function.  I know the DVI-to-VGA adapter, cable and monitor are all fine, as it functions perfectly when connected to the primary/upper DVI output.  But neither of my two monitors are displaying anything when connected to the secondary/lower DVI output.  The system isn't detecting anything attached.

I've got the latest drivers.  This is my first Radeon card, so forgive me if I'm missing something obvious.  Basically I have some simple questions that I can't seem to find answers for in the official blurbs...

I have an AMD VISION Engine Control Centre available when I right-click on the desktop.  This is the only AMD/Radeon control panel I seem to have.  Is this the same as the Catalyst control panel I'm reading about?  Should I be able to manage all the relevant graphics card features from this control panel?

I'm assuming that one would just plug a second monitor in to the second DVI output, and it would work (that was the way on Nvidia cards).  Do I need to do something to activate the second output, or is the card damaged?

Any help would be much appreciated, thanks!

Same problem here. apparently you can't have 2 VGA monitors (which are analog) on these cards because only one DVI (the upper one, DVI-I) has VGA support. the other does not (DVI-D, only digital).

i'm trying to solve it by re-installing my old radeon to run the second monitor, which is proving difficult.

So it's a known technical issue then, rather than a duff card.  Hrm.  Well I suppose finding a workaround is slightly less hassle than sending the whole rig back.  I don't have another Radeon to use though, so I'll have to be creative...  many thanks for the info!

Just wondering...  I have inbuilt graphics on the mainboard, could they be activated and used?  I only want the second monitor for displaying my web browser and Winamp, it doesn't need gaming-level power behind it...

look on my topic for solutions

I heard the onboard graphics won't work...

don't know if it's true

Aye, my machine came with tape over the onboard graphics ports, it looks like the mainboard doesn't have Win8 drivers, at least not yet.

@X3N0Wolf - See - How-To & FAQ section of forum(you should find answers to most of your queries).Also the "help" in VECC.If no luck there,see **STICKY** Please read .........,& supply that info.
