Xbox turns on multiple TVs

Your tv might have a setting to turn on when you turn on something attached to it. I also experienced this problem and I solved it with the settings on my tv, I’m pretty sure you can’t solve this from the xbox yourself at least from my own knowledge

Likelyhood is the Vizio tv's you have both run on the same code for this function. Are they also smart TV's connected to the same wifi?

So I looked into it a little deeper and I have an xbox one x and there is no setting for me to run the power through HDMI. It asked for my TV remote code. I ran the set up a few times to see if there was an option I was missing, but no luck. And on another
note. I'm a bonehead and forgot my biggest TV is an LG and the smaller is a Vizio smart TV. They just happen to both use very similar IR codes, so doesn't seem like I will be able to fix the problem.

Have had this problem two a lot of the time companies use same code to control all there products i always have two different brand tvs in my lounge

what ir sensor u are all talking?

for me the hdmi connection is turning on and of my tv.
