How do I connect my HDTV to an iMac when the distance is arround 15 meters between the iMac and the TV (HD)?

Question

For instance: Can I use an adapter between the Minidisplay cable and a 15 meter long HDMI cable?
Or could AppleTV be a (wireless) solution to the problem? Can AppleTV only interface sound to an amplifier through the optical interface? Are there adapters between optical and good old phono connectors available?
I guess I could also use a Mac mini, which has an HDMI port. But since I want an Apple monitor with a Mac Mini and 27" is too big for my work place, I can't seem to find a smaler Apple display than the 27"Thunderbolt or LED Cinema screens. Is that really so? No smaller Apple displays available any more?
If none of the above solutions are good: I am open to all good suggestions to how I can have a Mac workstation (iMac, Mac Mini, others) that is also connected to my HDTV, 15 meters away from the workstation.

If indeed you have a Netgear Hub, then that is the wrong piece of network equipment.  If it is a Virgin Netgear router, then that will work.  The connection must use a router.
Unfortunately, there is no software from HP to help you install this printer (assuming your new iMac has OS 10.8).  So, we will have to do it manually:
1. Reset the printer.  Pull the power cord out of the back of the printer for 30 seconds.
2. When the printer turns back on, on your Mac look for a wireless network that begins with 'hp", likely "hpsetup".  Join it.
3. Print a Wireless Network Test from the front of the printer.  Note its IP address.
4. Type that IP address into Safari web browser.
5. Navigate to the Network or Wireless tab and look for Wireless Setup Wizard.  Run it.
6. Finally, connect your Mac back to your regular wireless network, go to Apple menu > System Preferences > Print & Scan and add the printer with the '+' sign.
