@longboat, do you know if you can set that TV up without connecting it to the network. I've been thinking I'd want our next TV to either not be a smart tv, or to work reasonably when not connected to the network. We don't need/want the smart features on the TV and the potential issues it could bring, but getting just a corporate type display with no smarts is quite pricey $$$. I would typically shy away from HiSense as a brand, but my experience with them was many years ago, so it's likely out of date.
That's a good question. You could connect to a network during initial setup, but then disconnect once everything is done. However, I'd think you should be able to get up and running without a network connection. I just went straight to connecting tonthe network and my phone - guess I have decided to sell my soul to Big Data in return for a life of convenience... I'll probably be dead before they get too much out of me - ha! At least I'm not on FB or Twitter.
All of these smart TVs are based on an operating system. The Samsung has a proprietary Samsung OS called Tizen, and the HiSense is running a google/android system. Others run Roku, WebOS, Amazon FireTV, etc.
Your question might be one to post on some specialized forums. Some might suggest just getting a computer monitor, but yes, those are higher-priced and designed for different use conditions. Biggest question would be if you could set up local channels from an antenna or feed from a cable source without any other connections.
This HiSense TV has a built-in microphone (as well as on the remote), but the mic can be physically turned off at the TV. I imagine people find it handy for asking Google questions without going to their phones.
Ridgeline content: they recommended transporting the TV standing upright, not flat. Ridgeline for the win!
