Sounds like something a $20ish active adapter should be able to fix. The box shouldn't care what's on the other end of the cable as long as whatever it is speaks the right version of the protocol.

The box would have to decrypt HDCP, swizzle one codec into another, and re-encrypt. I spent about $50 on dongles and the better part of a weekend pursuing that angle to no avail. Sony didn't make the announcement ahead of time, so nobody had an FPGA module ready. Of course, a cynic would say that was the whole point. I wasn't alone in having this problem -- the support forums were overflowing with outraged threads ab…

Active adapters of the sort you might need probably start around $70 and go up depending on the ports required. To get a 4k hdmi 2.0 to dp adapter would cost like $120+ for example.

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.

(ot: should that be clueless^Whelpful, or is there some new convention I'm not aware of? ^ still means "ctrl" right?)

It's an old Unix convention: ^W (Ctrl-w) would remove a word using the Emacs keybindings. So in place of striking out a word, you'd put ^W and the replacement, as you would when typing it out ("clueless...err, no, wait...ctrl-W...HELPFUL").

Sony dropped playstation support for my 4K monitor in an irreversible software update, forcing me to buy a smart TV :/ Also: the new smart TV bootloops if it can't connect to the internet for more than a couple weeks at a time (it wants to refresh its screensaver ads). You can run, but you can't hide.

If you open up a smart TV, isn't the "smart" part of it basically an embedded ARM cpu SBC, with a somewhat standard connection to the LCD cable? If so, how hard would it be to rip out the smarts and put in a passive HDMI to LCD converter board?

This exact strategy is mentioned elsewhere, and it appears there are people trying to reverse engineer the base firmwares as well.

TIL about Network Error Logging[1], which is having browsers send you reports that your DNS isn't resolving, your load balancer is timing out (HTTP / TCP errors in general), or your TLS certificate is invalid. Basically all types of issues that don't end up in your own application server logs. Report URI should lead with this (it's not even mentioned on the front page)! It's super useful for every site, I can't think…

This is the actual tech, rather than a commercial solution: https://w3c.github.io/network-error-logging/#introduction https://developer.mozilla.org/en-US/docs/Web/HTTP/Network_Er...

This looks incredibly useful! It'll also probably tell you who is using Pi-hole though.

Doubt it would work. Hardware is commoditized and low margin. That's why TVs are embedding internet advertising, to make fat stacks from their otherwise barely profitable products.

Not all hardware is commoditized.

I do not understand why so many other markets have a number of luxury/craftsman brands and in computers we only have Apple. Cars have tons. Even woodworking has 2 built-to-last brands and 2 others that like to flirt with that moniker.

You will have to pay though, if you want the company to stick around. If you buy something that lasts 3x as long then they get less revenue from you, and the smaller volume means every sale includes paying off the initial R & D.

I recall when Lian Li first came onto the scene and the notch-up in ergonomics of computer cases that followed. Maybe we need something like that for consumer electronics.

The problem is that people like small and clean, which is where Apple excels (to the exclusion of accessibility), so I wonder what bomb-proof consumer electronics built for modification would look like.

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…

Do these boards support HDCP?

What about factory reset?

This is why you segment out your WiFi, I have 4 SSID's 1. Normal Traffic 2. Guest 3. Security Devices (Camera's, and other Home Automation) 4. Media Devices (Roku, FireTV, Smart TV's, etc) media devices only have access to my home Plex server and the internet nothing else

I just have a GLiNet travel router I picked up for $20 that is open and not connected to anything. Any "smart" devices get connected to that so they can talk to each other but not the internet.
