Earlier this year I reconfigured the setup of my television in my master bedroom. I previously had a shelf I could put media devices on, but it was an eyesore and when I traded my TiVo HD for a TiVo mini I decided it was time for the shelf to go. My new look is clean and minamilistic. In addition to my TiVo, I have an Apple TV that I needed to mount in such a way that it was usable but not obtrusive. The solution was to put a few pieces of 3M Heavy Duty Mounting Tape on the back of the Apple TV and mount it to the top right of my television. Because the current Apple TV uses old style IR remote that requires line of sight, I’ve found that mounting the Apple TV at the very top of the TV with the IR port facing upwards allowed for the best reception. Perhaps the IR signal bounces off the ceiling, but I've had no problems with the remote when the TV is mounted in this configuration.
You can buy mounts for the Apple TV, but this was clean, simple and much less expensive. The only down side is that it can be difficult to remove without marring the back of the TV or the Apple TV. You’ll want to use caution.
I can’t take credit for this tip, it’s no doubt been around for a while and first came to my attention when it was used by the professional installer who put a TV and multimedia system in our office conference room. It’s a handy idea.
