I'm running an HDMI over ethernet extender for my living room tv, and then I have a wireless transmitter sending the signal to a receiver for the master bedroom tv since I can't get a cable to it. I have yet to find a simpler wireless solution to get the signal elsewhere, but at least I have a monitor in the two areas we are at the most.
I have 2 LCD screens, one at the NVR and one near my front door. At the NVR I have a Monoprice HDMI splitter. From the splitter one HDMI cable goes to screen at NVR and one goes to LCD near my front door.
