    I looked up "iMac 8.1" on everymac.com and it indicates this model has a DVI output, not a miniDisplayPort output.  Are you sure you are using the correct adapter?

     

    Also, your TV has to be set to the same HDMI input that you connected to your iMac.  If its set to a different input, the Mac will not "see" your TV.   (eg, if your iMac is connected to the TV's HDMI-1 input, on the TV you must select the HDMI-1 input).    Note, also, that some TVs only support computer connections on certain inputs.  Check the manual for instructions on this.  (On my Sony Bravia HDTV, the manual is explicit that computers need to be connected to HDMI-4, for reasons not explained.)

    The other issue with your older 2008 iMac is even if you get the right adapter and you can get picture from your computer to the TV, DVI doesn't output sound.

    You would need to use your iMac's headphone jack with a a special cable that has mini stereo plug at one end and splits the cable into a Y configuration with left and right RCA jacks to plug in the back of the TV for the iMac's stereo signal.

    What is your reason for hooking up your iMac to your TV?

    There is another solution if you own a new or newer iPad (iPad 2 or greater).

    If involves having a wireless router and your iMac, Apple iPad HDMI adapter and an iOS app called Splashtop Remote.

    You need a mini DVI to HDMI cable for your video.

    You are using the wrong cable.

    You need one of these.
