Another thought. The stb is sitting by our “main” tv. It is at one end of our house. The other 3 tv’s I want to hook up are at the other end of the house and in relative close proximity to each other.....within about 40’ of each other. But distance to rhe main tv is over 50’.
Can I split the signal at the main tv, run a cat5 extender to the area of the other tv’s, then use another hdmi splitter to send to the 3 tv’s? In other words, can the splitters be cascaded?
