Booting problems VIZO 70"

  • Hi, I'm very new to this. I have a Intel NUC DN2820FYKH loaded LibreELEC and boots up fine on my older 32" vizio but when I plug it into my 70" vizio and boot it up but it never works. I see that when LibreELEC is booting up it goes through a few resolution changes, but not sure what that means or if it is even part of the problem. Basically what I have been doing is staring it up on my 32" then replacing my HDMI to the 70" and I watch TV on my 70" but it's becoming a nuisance. Can someone help me?
