I finally got around to returning the HDMI switch i bought last December. The first one didnt work right out of the box. The second one did, but gave me problems the next day. No audio, lower definition, loss of colors. Strange it only happened from my cable box, not from the Firestick which was still ok. Since it would work when unplugged for a while, but after a day, it wouldnt work right, the unit is defective. So i am looking for a at least 3 input 1 output HDMI switch that can handle 4k video from things like my 4k Fire Stick. I need it to be controllable via Harmony, so Alexa can control it as part of a routine of turning on the TV, switching to the Fire stick. Any recommendations ?
