ATi 5770 - VGA Displays

[anterka]

I read somewhere, EyeFinity only works with digital signals, such as DVI, but I would like to use 3 display via VGA.

So my question is, can I connect 3 monitors via VGA, to a 5770 and use EyeFinity under Windows 7 ?
Will it merge my monitors to a 3840x1024 display ?

Thanks in advance.

im afraid not mate.

eyefinity on the 5770 would need to incorporate 2xdvi with the Displayport using an active dvi - displayport adapter.

you could use a VGA to DVI adapter then use that to connect to Active Displayport adapter! Im sure i have seen people running that way.

Also all screens need to have the same res.

Not strictly speaking correct. I'm sure we've had members use a DisplayPort-to-VGA adaptor and DVI-to-VGA adaptors with success.

+1 I have got a DP to VGA adaptor that I use for 1 of my projector, they work very well.
Most poeple tend to have better luck getting these DP>VGA adaptors working than they do for DP>DVI.

DVI>VGA adaptors are also known to have proven them selfs as working very well.

So you would require 2x DVI>VGA + 1x DP>VGA adaptors, the DP>VGA adaptors are also quite cheap ~£15 to ~£20 for mini-DP>VGA.

I've 5770's and I'm sure i'm using one or two DVI-VGA adapters back there, in work now so can't confirm but 99% sure.

this applies to the 6950 (sapphire) maybe its the same with other brands and models
of the 2 dvi outputs only 1 is dvi-i the other is dvi-d, meaning that only 1 vga monitor is supported
learned that the hard way only 1 vga monitor but only 1 dvi cable ;)

I hope you don't mind me jumping onto this thread, but my situation is quite similar: MSI 5770 Hawk.

According to the manual, it has:

* display port
* HDMI port
* DVI-I port (HDMI supported, HDCP supported, dual link DVI-I output supported)

My only crt is connected to DVI via DVI->VGA adapter. I have another 2 old screens standing around, but if I got it right, the best I can hope for is to connect one more via DP port !? You would recommend a direct DP->VGA adapter ? I reckon DP->DVI and then DVI->VGA is suboptimal (if it works at all).

Does any of the supported DVI things help me in any way ?

Thank you in advance.
