For three monitors setup

Not going to work, your card can only output a single analogue signal.

You should be able to drive two of the monitors directly with the 5770, one on vga and one on DVI. The last monitor may need a displayport-vga converter. I'm not so sure whether this should be an active or passive converter or if it even matters.

It would have to be active and would also be expensive as it would have to create a new analogue signal not convert an existing one.

Like I said I wasn't sure but thanks for clearing that up. I've seen some adapters come in about £24.

These were some of the cheapest I could find, there were other adapters which were costing £35-£45.

There is something else you can try before going down the displayport adapter route. Depending on your motherboard you may be able to plug your third monitor into it, either directly or with a DVI-vga adapter. I don't know how well it works with AMD systems but it works really well with intel systems. But again it depends on your motherboard and what connections it has. About the only downside would be that it won't support eyefinity, but I would not be looking to use eyefinity on this card.

Those adapters will not help the OP and I don't think you truly understand why. Once again the card can only run ONE VGA monitor at a time, just one.

I'm not going to argue with you over this. It's not worth it.

No it isn't because I'm correct. Only one VGA monitor can be used at any one time, all the others HAVE to be using a digital signal.

 

[uguryegul]

Ok. Thank you very much. If i have a displayport monitor, i can use the eyefinity. First monitor is dp second dvi and the last one vga.

That should work.

I bought a dp to vga converter (active). It is not a expensive It is a 25$. My first monitor have vga and dvi. Also i found two monitors. Both are only vga outputs and eyefinity is work. Now i use 3 monitors.

Sorry this is not true. two vga monitors work. also if one vga monitor connect to dp output of graphics card, three vga monitors work.

Can you post the technical specifications that show how the card can output three separate analogue signals then?

SAPPHIRE HD 5770 1GB GDDR5 PCIE

2 x Dual-Link DVI
1 x HDMI
1 x DisplayPort

first connection is displayport to vga converter. this monitor has dvi and vga inputs.
second connection is dvi to vga converter. this monitor has only vga input.
third connection is the same as second connection. dvi to vga converter. this is the only vga input. ok.

in addition this graphic card manual show that this connection.

Cypress only has the one DAC but you reckon yours has three? Really?
