I would hate to sit on the sofa to do my computing, I have a desk for that.
The best solution is to have a desk computer for regular computing tasks, and a HTPC (home theater PC) for a PC connected to a big screen TV.
I would like to send my HDMI signal wirelessly to my TV for gaming though.
From what? Do you have your computer sitting next to you on your sofa? Or is it near the TV/monitor? And then where is your mouse and keyboard connected? Via wires to the computer sitting on your sofa?
Plus, understand HDMI cables carry VERY COMPLEX and
MASSIVE amounts of data at very high speeds (read:
HUGE amounts of bandwidth). This includes high definition video in high resolutions with rapid refresh rates, plus
6 discrete channels of high fidelity audio, plus HDMI control data on top of that. The sophistication and complexity of both the transmitter and receiver radio circuitry is immense.
Not so with a wireless keyboard and mouse that need only deal with tiny amounts of slow speed data. So using a wireless keyboard and mouse while sitting across the room is the best solution, by far.
If you were a road warrior and needed this type connection to a projector or large monitor during a presentations, then something like
this would make sense. But in your own home, in a fixed (not mobile) environment, a wireless keyboard and mouse make better sense.
