My parents are getting a new tv, and are asking for recommendation. I think all I can influence is the brand/model (not realistic to propose rpi and more complex systems). I instinctively avoid google/android and lean towards anything else open source, so probably LG WebOS.. But I had bad luck searching for more detailed comparisons. Maybe you have experience or opinions?
If you want a true dumb TV, buy a commercial grade display made for digital signage. Bit more expensive, but designed for 24/7 operation and has none of the smart tv fat.
No, I work in corporate AV, so I'm buying higher end digital signage for most applications at work.
NEC and Philip's I've been using lately, but they are just the cost effective ones now. LG, Samsung, Sony, all make good displays.
Digital sign usually dont have any smart apps, and if they do you can fully disable them.
They also have all the advanced features you could want. Serial and TCP api, multiple ports of various formats, auto on with sync detect, etc.
For personal use, my last three have been Visio from Costco, and while it has the apps, I just never connect to the internet.
I have seen guides online to open up a display and disable the smart elements, but that seems overkill to me.
One thing to watch for, I've heard but haven't witnessed that many displays are getting way more aggressive about auto connecting to wifi for sharing data and updates. If someone has unsecured wifi near by etc.
Yes and no. This is for parents, so ease of use is a huge factor.
The processors in smart TVs are often crap, plus who know what updates and monitoring they are pushing on you.
With a dedicated media device you only have one company to deal with. Personally, I use my playstation for everything, but for my mom a Sony bluray with the apps works fine.
At the end of the day, they'll want netflix, amazon, youtube, hbo max, etc, and you get a way better experience with a media player vs smart tv. Sony is a known evil as it were, their hardware is good, and they generally don't fuck up firmware updates.
I got a cheapest Android smart TV and never connected it to the internet. On HDMI1 there is Amazon Firestick for the occasional Netflix use. On HDMI2 there is Kodi for every day watching. Because of how modern TVs work, both these extra boxes can be steered with the TV remote.
My partner and I were gratefully surprised when we bought a cheap Hisense for their cozy space (to isolate when overstimulated and just play some games) that in the setup it offers the option for a 'dumb TV' mode with no requirement for internet. In addition you can reject the user agreements and still use the TV. It boots straight to HDMI, no pop up ads, and is snappy.
