At that price they're probably passive adapters, you need active display port to dvi adapters when using more than 2x screens

what does active displayport mean -.-

From the eyefinity FAQ on AMDs website:

What are the basic requirements for connecting multiple displays?
Connecting multiple monitors for AMD Eyefinity technology couldn’t be simpler. There are four easy rules to remember:

The first two monitors can connect to the graphics card with any display output on your product: HDMI, VGA, DVI or DisplayPort.
The third (or greater) display must be connected to the graphics card via DisplayPort.
If your monitor does not have a DisplayPort connection, you will need an inexpensive active DisplayPort adapter for it. DVI to DP adapters can be had for less than $30 USD.2
Every family of GPUs supports a different maximum number of displays.

could i buy a display port cable and run my ultrasharp through that then run the 2 others through dvi? because the dell does have a display port the korean and the old hanns g do not.

will a display port cable be cheaper then buying an adaptor?

also it says "greater" monitor obviously thats my korean based on resolution so if thats the case do i need the active adaptor for that monitor or will it still work if i just buy the cable to connect my dell using the display port without a converter, and if doning that will that be forced to be the main monitor?

By greater its literally talking quantities - its an eyefinity FAQ which requires 3 monitors of, or running at, the same resolution. However the info for connecting multiple displays is still relevant to any setup.

Your 1440p monitor will need to be connected to a dual link dvi port to be driven at 1440p resolution, your dell with display port to the mini display port using straight through DP->mini DP cable and your 3rd (assuming its resolution is less than 1920x1080) can go via hdmi, dvi (or via an hdmi->dvi adapter) or maybe your $6 passive DP adapter. Then you should be good to go.

Display ports won't be active during boot so the first time you'll see anything on the display port connected monitor is at the windows login or desktop

You won't be able to setup eyefinity for the reasons above and in that FAQ I linked to but I think you knew that anyway.

thank you so as long as something is connected through the display port it should work right? why is it that the display port to (hdmi to dvi cable) set up wont work then,why is it nessecary to "actively" convert the singal from display port to dvi? I just dont want to waste money on buying another wrong item!

These graphics cards can only output to 2x dvi-type interfaces at any one time (hdmi uses dvi video so is included in this figure). I don't know the exact reason why you need an active adapter but going by the typical definition of active vs passive it would imply to me that a display port is capable of outputting dvi video too and therefore a passive adapter just does a pin swap and socket conversion to allow you to plug a dvi cable into it. However this takes up 1 of your 2 allowable dvi outputs for your card.

An active adapter uses the display ports native signalling and appears to the graphics card that you're using a display port device but requires some active electronics in the adapter to do the protocol switching between display port and dvi. This therefore doesn't use up one of your dvi allocations but because of the more complex adapter, increases the price.

I've never read anything to support this but what I've observed fits this theory and passive and active are terms used a lot to describe features like this. Perhaps someone who really knows can shed some further light as to what a passive display port to dvi adapter actually does. However if you assume my description is good enough, it should help you to understand why your original setup didn't work.

However. seeing as you have a monitor with a native display port interface, if you connect this to your graphics card mini display port then for the reasons above, isn't using one of your dvi allocations. This means your other 2 monitors can be plugged in wherever, dvi, hdmi or your mini display port passive adapter as you're only using 2 dvi devices now. This is all reliant on using a display port cable for the display port capable monitor. Look on eBay, you should be able to find a display port to mini diaplay port cable for a few $.
