Display BlackMagic

[A_Wild_SkyBear]

I'm not sure how much help Ill receive from this but I'm desperate. I'm almost done with one of the coolest mods Ive seen (Ill upload build log when I'm done). I bought one of these displays: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=201073707698&ssPageName=ADME:L:OC:US:3160

I plugged it into my GTX 550tI as a second screen using a mini HDMI to full HDMI, and as my main monitor I'm using a Westinghouse 27inch 1080p. When the display is plugged in the back light illuminates, but no image is shown, and then the brightness starts throbbing. My computer and even my Nvidia setting recognize the monitor but nothing is displayed.

I really need help, I have no idea what to do or where to go and hoped that I would find help here (as you guys tend to be excessively helpful).

Please help.

 

-Just to clarify the smaller display (the one i bought from the link isnt displaying video)

Hmm wait a second... is the smaller (the one on link) not displaying or the main one?
