And I use a 55" 4K TV as my "monitor", because sub-$1,000 >>30" monitors with internal 3D LUT-based color calibration aren't a thing. And, while I don't use the speakers, the TV's S/PDIF output is nevertheless handy for routing the audio output of whichever of the four HDMI inputs is active to the single S/PDIF input on my audio interface. Finally, the TV has an RS-232 port that allows control of essentially all of t…

What is said TV response time? If it's bigger than 2 ms then that's a no go for me.

Because you have a 500hz HDMI output? Yeah right.

Is it? I’m still holding onto my TV from 2014 because it doesn’t have “smart” functionality. Every time I look at new ones I can’t find good dumb ones.

What are your thoughts on the Sceptre brand?

I loved their 40-inch screens.

Unfortunately they no longer make them. The 43-inch Sceptres have a HUGE black space between the pixels, which you will totally notice if you try to use them as desktop monitors.

Just don’t ever connect it to your network.

Sure, till they start adding cellphone-tower enabled connectivity. Your move, consumer.

RF jammer. Checkmate.

Endgame is the FCC forces consumer-data-control on the industry because it's the only way they can get the 5G/GPS jammer problem back under control.

And then they forget to update it or nvidia discontinues it and someone hacks in to it and your room mic gets posted on one of those open ip camera lists. This is not some tin foil hat idea. You can go on reddit and browse peoples personal spaces being broadcast for everyone to see.

… how does a mic that is embedded in a remote control turn into a camera?

I don't mean that it will become a camera, but that it will be listed along side them. "Listen to this random persons living room / bedroom" makes for some entertainment for others.

This isn't difficult: TVs should not be "smart". TVs should be incredibly dumb. They should be screens for displaying stuff. That's it. Nothing else. No network connection of any kind, no apps, no software beyond that necessary to do basic setup of how that screen works: brightness, input selection, etc.

What annoys me most about "smart" TVs is they are complete crap. I tried to use a friend's TV that cost several thousands. It had an "air mouse" remote. But the thing was more laggy than the first time I tried a full GNOME desktop on my Pentium 2 back in the day. Barely usable. I have a Raspberry Pi 2 that's been running for years now hooked up to a projector that wipes the floor with that piece of junk. But he's now stuck with that interface for years.

This is the main use case of 5g iirc. Enabling millions more devices to connect to the network. What an absolute nightmare we are about to enter. "Just don't connect it to the network" is no longer a valid answer.

I will start building 5G jammers. The FCC can eat a bag of dicks. Apparently even 5G-NR has an equivalent of the wifi "unauthenticated deauth" intended for emergency quench of uncooperative devices. The cellphone location data abuses revealed over the last three years have led to a remarkable increase in the number of GPS jammers out there. Gaussian-noise blurred, the good ones that can't be notch-filtered.

I think the real answer is that the EU will come up with some "Right to disconnect" which mandates that all devices request user consent to connect and retain as much functionality as physically possible while in offline mode.

The technical battle is basically lost on IoT once they can embed modems.

That kind of control is what DoH breaks and I'd…

There isn’t an effective solution for a device which ignores local network policy other than returning it so the manufacturer pays the cost of designing a bad system.

With the side effect of your local vendor refusing to do further business with you, "the problem customer", with your "unreasonable demands" and technobable.

I’m responsible for a bunch of IoT hardware, and every firmware spec I write includes a note on not using the DNS servers provided via DHCP. While sure there are companies explicitly doing this to avoid filtering, at least in my case it’s because a significant proportion of DHCP servers are configured to send DNS to your ISP, and ISP provided DNS is almost universally terrible. They’ll ignore TTLs, rewrite NXDOMAIN r…

I think that’s a gross overstatement about ISP DNS.

Certainly in Europe I’ve not seen anything even close to that.

I’d love to see a good country-by-country survey on ISP DNS to see just how common this manipulation is.

They’ll ignore TTLs, rewrite NXDOMAIN responses into the IP address of their ad-laced web search, and occasionally just highjack every single query to send you to a page saying you’re approaching your bandwidth quota Universally?

It’s not just the U.S. A problem report once lead me to discover that the Spanish company Telefónica cached DNS results for years longer than the TTL. My error monitoring also picked up content injection (prior to HTTPS) and DNS hijacking around the world. Before going with the conspiratorial take note that Mozilla shipped DoH early and both Microsoft and Apple implemented it. Untrustworthy ISPs are a real problem ev…
