Vizio P75QX-H1 with Logitech ultimate home


Novice Member
I have the Harmony Ultimate Home and it has worked great with my last TV. I just got a brand new Vizio P-Serious Quantum X P75QX-H1 and am having a lot of issues getting this set up. I originally went into my hub and removed my last tv and added my new one, then changed all my activities to use the new tv and set the inputs.

But the harmony is not able to change inputs at all. None if the inputs will change it just stay on the same one it’s on but I can see it powering on and off the devices for the activity. It won’t even turn the tv off.
