For any Australians reading, JB Hifi still has dumb Blaupunkt TVs. They're neither big nor 4k, but if you're weird like me and feel technology peaked in 2009, they're perfect.

Is there something wrong with just buying a normal TV and not giving it your wifi password?

The fear is that the TV will still be annoying, with popup menus and "Oooh! No WiFi! You need to fix this!" alerts.

A “normal” tv doesn’t need a wifi password ;)

Just as long as you never have any guests that want to be helpful and connect it to the Internet either via your guest wifi or their own phone's hotspot so they can watch their Netflix or whatever on it.

Or you accidentally connect it to your streaming box (Apple TV, Roku) with an HDMI cable with Ethernet:

The streaming box will have to be complicit and act like an ethernet switch or NAT router (in case of Wi-Fi not supporting WDS so can't be bridged) to passthrough the connection.

There's no reason to believe this won't be a configurable option on the box itself, but this is a moot point because I have yet to see anything in the wild actually supporting Ethernet over HDMI.

They soon will be able to connect to your neighbour's wifi via Amazon Sidewalk

This gets raised all the time but I just don't see it being necessary - the vast majority is happy to voluntarily provide it with an internet connection. The ones like us who fight it is a very small minority not worth spending on including modems/Sidewalk/etc in every TV.

I wanted an 85" TV, and unfortunately Sceptre only makes up to 75".

I ended up with a Costco 85" LG and unplugged the WiFi card before turning it on, and so far it's worked very well for me.

I wish I could have voted with my wallet on this.

Unfortunately LG has terrible sound - but a soundbar works well.

Unfortunately the LG soundbars - which integrate well with the TV - use a wifi based wireless subwoofer. the soundbar becomes a wifi access point.

There don't appear to be any wired soundbars. I guess a component speaker system + receiver is the solution, which is probably much better sound anyway.

Is there a dumb oled? I want a dumb oled tv and monitor, monitor oled market is surprisingly slim.

The Gigabyte Aorus FO48U might work for you. A dumb OLED monitor the size of a small TV. Catered towards the gaming market of course but is a viable option: https://www.gigabyte.com/Monitor/AORUS-FO48U

sceptre seems to be the last brand offering dumb displays

I am just waiting for the first "smart" computer monitor

They’re called all-in-ones. They’re very popular. The Apple version is called the iMac.

Samsung has 27"-32" monitors running Tizen

you can buy monitors running android now :)
