Three monitors with only a HDMI and DVI output? Radeon HD 7450

I have a Radeon HD 7450 that came with my new PC and it has 1xHDMI and 1xDVI output. I have 3x LG E2742V monitors (each with HDMI, VGA and DVI inputs..no displayport). Everything I read about "Eyefinity" and my card says it allows for 4+ monitors...but exactly how do I get third monitor to work with only 1 hdmi and 1 dvi??

Monitor 1 = HDMI
Monitor 2 = DVI
Monitor 3 = ???

Can you tell me what other equipment is necessary and what needs to connect to what?

Thanks in advance!

  1. Active display port to DVI adapter. It must be a active adapter.
  2. Thanks, but I'm confused about how these adapters allow for a third monitor. For example, if I have an active displayport adapter (like this? http://www.newegg.com/Product/Product.aspx?Item=N82E16814999030?)....I'd plug it's female DVI into my graphic card's male DVI....but then what??? Where to I plug the DisplayPort into since none of my monitors have a DP input?
  3. if you physically only have 2 outputs on that card, 1 hdmi and 1 dvi, you can only use 2 of your monitors.

    most of the radeon hd cards made for more than 2 monitors have 5 outputs on the back (and take up 2 slots on the case), 2 dvi, 1 hdmi, and 2 mini display port, which if you had that, you would plug 2 monitors in via dvi, and 1 via mini display port (with an active adapter).
  4. that card can't even handle 3 monitors, I've had one, buy a 750 ti, they are cheaper now that 9 series Geforce cards are out
