I have yet to see one that won’t eventually let you use it as a dumb display after you dismiss one (or more) nags first. But I’m sure that’s coming eventually. The worst offender I found yet is the “cheap” Black Friday sale Amazon Fire TV my boss got to use as a security monitor in one of our satellite locations. That fucking thing won’t even show a picture until you dismiss its network nag, and then its sign-in-with-Amazon nag. At least I found you can disable the Amazon account nag in the options. The network connection one you can’t.
We’ve just resolved never to turn it off. You can’t dismiss the nag screen with the bezel buttons, either. You have to use the remote, so that’s now permanently double-stick taped to the desk the TV is on.
Next time he’ll just buy a fucking computer monitor like I told him to.
