Hi ,
I have recently purchased a Sapphire radeon hd 6770.The card is equipped with a single dvi socket, a single displayport socket and a single hdmi socket. currently i have a single vga monitor connected to the dvi socket via the bundled adapter.
my current monitor is an LG 1946S equipped only with a vga connector.what i would like to do is buy 2 more of thes LG monitors and use them in a 3 display eyefinity setup.

although AMD says at least one of the displays must be have a displayport i have been told i there are work-arounds for using just vga monitors

So my question is:Is it actually possible and if it is possible , what cables etc would i need to purchase ?

many thanx

You can't use Eyefinity to use 3 VGA (analog) monitors. You must use monitors with a digital interface (HDMI, DP, DVI). You would be better off buying 3 matched monitors that meet the digital connections requirements.

While this is a good adapter, it will not help with the "VGA only" monitors. It is a good adapter to bridge a DVI/DP connection, but not for VGA.

Still, the best advice would be to get 3 monitors that have the needed digital inputs and then to use the 3 digital connections on the video card itself.

of course the best option is to buy 3 new monitors.... but, couldn't he use 3 dvi->vga adapters along with the dpi->dvi adapter..

there wouldnt be any analog signals in the dvi when going dp-dvi, ie it is DVI-D only. DVI-I has both analog and digital signals in the same plug, the dvi-vga adapter just routes those analog signals through to the vga out..

Nope, the dual-link DVI has nothing to do with supporting a VGA connection. DVI-D is a digital only DVI connector that can't be used with a VGA adapter. DVI-I contains the circuitry to support a VGA connection. DVI-D is not necessarily a dual-link connection.

See below for more info on DVI connections:
