Never add your WiFi credentials you your TV. It doesn’t let you remove them so you’re only option is to create a “dummy” network (ex: phone as a hotspot) and switch to it. Also, watch out for clueless^helpful friends and relatives who try to “fix” your TV’s WiFi.

My wife connected it to our wifi the other day ... I almost lost it.

A factory reset should fix that TV right up.

Specifically for TVs, you can get a new display driver board for whatever panel is in there. Eats HDMI/DP, spits out eDP or VBO or whatever the panel format is. Often these are pretty basic, with a minimal OSD pasted in by the Shenzhen seller who configures the thing to your order. Personally I'm trying to get my hands on the SDK for the software that runs in the driver chip (does the OSD and the scaling and everythi…

HDCP strippers are a thing now, so this shouldn’t be a concern.

> I’m just waiting for the day when all TVs require a working internet connection and we have to start hacking their hardware and software to protect our data. These days won't come. What will happen instead is TVs will start coming with embedded SIM cards for cellular data connection (prepaid or otherwise negotiated between TV vendors and telcos), and then we won't have any choice in the matter as consumers, short o…

> These days won't come. These days are already here. My TCL bootloops if it doesn't have an internet connection to download ads from, and if you call support, they'll happily walk you through getting it connected to the network.

What happens if you tell them that you don’t have an internet connection?

It will continue trying to connect to your SSID. Failing of course, but it will still pollute your channel with garbage packets.

I really wish I could just remove the wifi chip. I'm tempted to take the rear panel off just to see if it's reasonably accessible.

Or just snip the antenna

> ... I wanted a 4K monitor. To all the folks reading at home... I would remind everyone that a TV is not a monitor. I got a relatively inexpensive LG 43in TV to use as a desktop monitor. I've had issues. Beyond the usual "make sure your graphics card actually supports 4K" and such, you also need to take some time to dig through the TV settings when you are using it on a PC. In particular, you definitely want to turn…

I'm calling what I want for my living room a 'monitor'. I want a TV that's a monitor, basically, not the other way around. For my computer, I use a 32" LG 4K monitor, and it's great. No 'smart' features found there. But I can't find a 4K monitor in the 42-50" range that has multiple HDMI inputs that is not incredibly pricey (e.g. broadcast/commercial realm) I could use in my living room.

Curious why multiple HDMI inputs matter, given a decent A/V receiver (a few hundred bucks) can handle it for you (along with waay better options for audio)?

They are more expensive because they generally have higher quality components and are not made to be disposable, and commercial applications have a higher price tolerance than consumers. Despite the common trope, "selling data" doesn't lower the price of consumer devices. You only see price-less-than-cost plays when companies are trying to buy market share (think Alexa, Google Home, early Kindle, etc).

Umm, no - this is not just a 'common trope'. The CTO of Vizio has stated in multiple interviews that removing the data collection capabilities of their TVs would increase the prices. Direct quote: "The greater strategy is I really don't need to make money off of the TV. I need to cover my cost." and "It's not just about data collection. It's about post-purchase monetization of the TV." [1] https://www.theverge.com/20…

Right, but the value of the data pulled from a single TV is probably around $10/yr (how could it be higher?). Over 10 years that’s $100 - sure - but do people keep Vizio TVs around that long?

AVRs are a huge hassle to deal with, and overkill when you only have 2 or 3 devices to switch between and/or don’t have many audio-only devices. AVRs made more sense during the days when we’d have CD players, tape decks, VCRs and DVD player, vinyl record players, cable/satellite STBs, and a game console or two all hooked up. Now it’s just an STB (if you aren’t a cord-cutter), a Roku/AppleTV/Chromecast/FireTV, and maybe a Blu-ray player (or BD-capable games console, which also doubles as a Roku/AppleTV/etc).

Or just keep hitting company officers with a tire iron until they fix it.

This might be a stupid question, but... Why do root certificates have to expire at all? The article presents this as if it's an immutable law of physics.

We have no real means of revoking certificates whose private keys have leaked. Eventual expiration seems better than nothing. Also, ciphers tend to become obsolete, so enforcing churn will help keep things moving forward. I'm not an expert here though, there may be other reasons.

I begrudgingly bought a 'Smart TV' just because I wanted a 4K monitor. But I use it as a dumb monitor and watch app-based content through an Apple TV. At least I'm reasonably sure the Apple TV will be updated for 5-10 years, and is a lot more disposable than a giant TV. My last TV worked great for about 12 years. No way Panasonic would've kept supporting it that long. Honestly, the thing I hate most about smart TVs,…
