My iMac will not connect to my display

Hello,


I just started using a second monitor (it's brand is Dynex but I don't know any other specs for the TV) for my iMac 2.7 GHz Intel Core i5 and I connected it via HDMI cable and mini displayport. After I turned on my second monitor, my iMac screen flashed black, which I suppose was supposed to happen, but nothing more happened after. I looked into display settings and the appearance tab never showed up, so my computer did not recognize my monitor. Also, when my monitor shuts off automatically, my mac screen flashes black again.


Is there anyway this problem can be solved?

iMac, Mac OS X (10.7.5)
