I currently have iMac connected to toshiba tv through minidisplay adapter to hdmi. We can't seem to get it to recognize that the tv is hooked up, we've tried unplugging and replugging turning each device off and on in different combinations. here's what I get on the "display" menu when everything is hooked up.

    Is the TV on the correct input settings?

    of course it's on the right input. I didn't state it was a picture problem as in "all I can see is my cable programs showing", it's an issue with the computer not recognizing there's a second device hooked up.

    Chances are high it's the adapter you are using, not all are created alike. If you are not using Apple's then I'd suggest buying one and then re-testing. Also not all iMac's support HDMI, exactly which iMac do you use?Finally when replying to someone trying to help you it helps to be polite, your last post doesn't read so.

    I had said to my husband that it's probably the adaptor but he didn't think that could be the cause - thanks for confirming that for me! All I can find about it the iMac is this if it helps...21.5-inch, Mid 2011,Processor  2.5 GHz Intel Core i5. I had read that some older macbooks needed to go mini display, to...dvi and then hdmi I think it had said. I was hoping that would've been resolved with thunderbolt. I'll check and see if we can exchange the adaptor. Thanks again! (and I would've been a bit more polite if I felt like they weren't being saucy with their response )
