Well...connection isn't an issue as my WiFi network is connected to the TV. I'm just wondering if an iMac can connect to the TV on my network. Not looking to watch TV show or movies, just my own content.
Well, I wish in your opening post that you had mentioned your goal was to mirror your iMac to your HDTV
wirelessly - I would not have bothered w/ posting the cabled options. Now it makes no difference what is on your computer's screen (your content, pics, or a movie playing), you want to mirror the iMac to your TV's screen, and w/o a cable - correct?
My HDTV is also on my Wi-Fi home network but I'm not sure how to really mirror my MBPro's screen w/o the use of a cable (in that case, I use an HDMI to HDMI cable); others will have to 'chime in' w/ some advice. Now,
Slydude mentioned an Apple TV which would easily allow you via Apple's AirPlay to wirelessly view your computer's screen on the TV, but you mentioned a lack of interest going that route. Dave
