It's not OLED, also looks pretty cheap?

I don't want a crappy, cheap, panel with no smart features. I want a premium panel without smart features.

Think like Apple Pro Cinema Display in TV form.

Exactly. That's my biggest struggle with finding a TV these days.

I want to make sure that the networking functionality is what I attached to it, not something built into the TV that I have no way of possibly disabling or removing entirely. With some of the relatively recent PiHole posts, it's become clear that some of these smart TVs are including some level of DNS resolution on their end to get around ad blocking functionality. They'll say it's for ensuring they can always download updates, but it's really for retrieving ads.

I want a display that's going to last longer than 3 years. This is one of my concerns with Spectre displays. I'm not sure of their longevity.

I want that display to have a great picture. I also don't think Spectre displays looked particularly great when I looked at them in the past. Maybe that's changed over time.

As I commented below in another thread: If the demand is high enough, a custom controller can be developed to match controller on-board Apple Pro XDR while keeping the price point significantly cheaper.

Just don't give it your network password, don't connect it to the wifi.

Ironic advice given what this post is about :}

I find the easiest way to make the TV dumb is to reject every EULA and ToS I'm presented with. Basic TV functionality can't really be disabled (not without making the device unfit for the purpose it was sold), and any further collection of data would expose the manufacturer to some massive legal liability.

And turn off 99% of the picture enhancement options

I have two tvs from them, bottom of the barrel Black Friday deals and they work great and seem fairly durable (they've both been through a few moves)

Picked up a few of these, they look fine and work great.
