Hi everyone! New to the forums, so if there is already a thread on this I apologize in advance. I have bought an HDMI switch (monoprice tech choice 3x1 HDMI switch) which works fine with my new tv (LG 60" year old) but does not work with my older tv (Sony Wega 50" 10 years old) even though the description says "Are you stuck with an older HDTV without enough HDMI ports for all your equipment?" Am I doing something wrong or do I need to order a certain HDMI switch model that will work with my older tv? The Wega only has one HDMI port and I'm trying to hook up my DVD/PS3/WIIU. Any and all suggestions are appreciated. I thank you in advance for your time and assistance.
