the displays are all running at different resolutions

(craig lcd tv can run 1080p but i use sudested 720p) display second screen display port>adapter(giggaware)>hdmi

if i unplug one the other 2 will work it does not matter witch one i unplug the other 2 will always work
Was that display port adapter an active one? You need an active displayport adapter that can actually transfer displayport signal into HDMI signal, not a passive one that simply rearrange the pins of this connector to another, to set up Eyefinity using 3 monitors without displayport.
Edit: your gigaware adapter is not an active one, that why Eyefinity setup failed to work.
