Radeon 6570, 3 displays.

[chosmernv]

I have Radeon 6570 graphics card. It has 1- HDMI port, 1 DVI port, and 1 VGA port.

I have three displays, Samsung(SyncMaster P2350), Sony(PlayStation 24" Display), and Dell (2007FP).

Samsung is connect to the DVI port.
Sony is connect to the HDMI port
Dell connected to the VGA port.

I can only get two of the displays to work through Eyefinity.

I have read that the only way to get a third display to work is it needs to have a display port.

Is there any way I can connect the three displays I have.

Unfortunately, you'll have to get an Eyefinity capable card, or add another HD 6570 and connect the third monitor to but it won't be Eyefinity though.

And for Eyefinity to work, all monitors must have the same resolution regardless the size.

like ilysaml said, you need a card that supports 3 simultaneous outputs. The cheapest one I'm aware of is here:

but it would be a downgrade in terms of performance. Are you just trying to hook up monitors? You aren't trying to game with 3 monitors are you?

And for Eyefinity to work, all monitors must have the same resolution regardless the size.

This is true, but you can use 3 monitors with different resolutions on a card that supports 3 outputs. You just can't turn it into a single large surface display. Windows Extended desktop options will still work fine.

True.

Looking @ the AMD website the Radeon 6570 does support up to 4 displays via Eyefinity.

■AMD Eyefinity multi-display technology1◦Native support for up to 4 simultaneous displays
◦Independent resolutions, refresh rates, color controls, and video overlays
◦Display grouping •Combine multiple displays to behave like a single large display

That's in case your card has a DisplayPort, but it doesn't.
