World is full of strange people. Because you do not need to entangle yourself with wires, they (moto) gave us screencast feature, and now people are asking about WIRES again!
TV sets now are coming with Screencast support but if you do not have this feature in TV then read next line....
I am casting (broadcasting) everything (movies, games, android screen, etc) on my 32inch LCD TV, even without wifi router.
I use Pandora S HDMI streaming dongle which does not need WIFI/Router. Direct wireless connection of phone with dongle (attached on HDMI port on tv)
With this device costing only USD27, I can broadcast my Phone, PC, Laptop, etc on TV all wirelessly
