Misleading to state that this turns your TV or set-up box into a fully hackable device, while the software just runs on a RaspberryPI

i was also googling for the supported TV sets and then i found it :D

I realize "Plasma" is the name of the KDE presentation layer across all platforms, but it's mildly awkward to see in this context considering plasma TVs have only been a dead technology for six years or so: https://en.wikipedia.org/wiki/Plasma_display

The name is generally really unfortunate, and I wish they would switch back to KDE for the Desktop Environment (and call the framework Klibs or KDElibs or something). Many people have positive associations with KDE, but associate Plasma with bloaty QML based desktop widgets from the KDE4 era. If they even associate it with KDE, and not with plasma TVs or blood plasma.

Literally what I thought the thread was about, and actually why I avoided clicking into it so long.

I hope they'll get some design help.

Unfortunately this was the first thing I thought too and is often the first undoing of open source projects. It might be an impressive technical feat but it _looks_ a mess. Software developers often make the worst UX designers and all that.

Truly modern TVs have much better scaling and frame interpolation than whatever your OS or media player can do.

Most people hang on to their TV for 10 years or way more than that. Expecting people to have truly modern TVs is a crapshoot. Only enthusiasts upgrade to the latest and greatest.

And unless you're a very informed technical savvy consumer who does his research and knows what he's buying, upgrading your TV might end up being a downgrade for you as you could end up replacing a perfectly good dumb TV with a new WiFi "smart" TV that spies on you and serves you ads.

No thanks, modern TVs!

I don't understand why people think electronics are supposed to die. Even if they do, it's often just some capacitors that died in the power supply. An easy fix!

Back in the day, there was a strong public perception/rumor that plasma screens would fail much sooner than other kinds. Maybe it was just a FUD campaign, after all.

Could have been FUD from manufacturers looking to push thier LCD TV over the competition plasmas.

I bought an LG OLED recently after giving up on my dream of finding a dumb consumer OLED. I assumed I would disconnect it from my network and use my Chromecast for media, but instead I've recently unplugged the Chromecast. The interface is surprisingly good, it has every app that I want and it's fast. I can press the Netflix button when my TV is off and be watching a show within seconds.

That would not be GPL compliant (both v2 and v3), so would not conclude the lawsuit. https://sfconservancy.org/blog/2021/mar/25/install-gplv2/ https://sfconservancy.org/blog/2021/jul/23/tivoization-and-t... https://events19.linuxfoundation.org/wp-content/uploads/2017...

A lawsuit against Vizio for GPL violation cannot compel them to open or release software from their OEMs. For example you are never going to get a functional driver for the display panel made by Panasonic. It isn't even clear that Vizio would be able to comply with GPL enforcement, since they largely just OEM TVs built by AmTran in Taiwan and don't do much more than slap a logo on it.

They should've looked better at their contract, then. It's not the consumer's task to make sure these companies and their suppliers stick to their licenses. If their suppliers ship software that's not compliant (i.e. the vendor doesn't follow GPL's requirements) then Vizio is not allowed to ship them either.

If they can't comply with the license, they shouldn't be allowed to be sold in jurisdictions where the GPL is considered legally binding; after all, they are violating copyright. Any damages from their vendors' malpractices can be resolved in a separate lawsuit if Vizio wants to hold them accountable but you can't hide behind your vendors to sell illegal wares.

As GPLv3 states:

> All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met.

If they can't or won't release the GPL source code, they can't legally ship the software as they haven't met the requirements for their license and if they do, authors of the GPL'd code could sue them for copyright violations.

In fact, this paragraph could bring them into even hotter water:

> However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

> Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

In other words, if copyright holders notify them of their violation and Vizio doesn't act in a timely manner, copyright holders could permanently retract their GPL licensed code from Vizio. Should a particularly important Linux developer choose to do so then that could effectively deny Vizio the right to ship Linux on any device it sells (to areas where GPL is upheld, such as the USA or Germany).

Actually matching framerates is a lot more common, for example to provide smooth playback of 23.976/24 or 25 fps when the native refresh is 60hz (not cleanly divisible). Usually this is done by going up to 72hz or 75hz rather than down but it's a lot better than keeping at 60hz and stuttering. Previously this was accomplished with something called telecining which.. isn't great.,

Shouldn't the optimal solution be to adjust the display refresh rate using vesa adpative sync these days? No need for shitty interpolation when most panels can run at variable refresh rates.

You can have multiple displays connected to an HDMI hub with different refresh rates. I have this problem with a projector that runs at 240 Hz in a TV that runs at 60 Hz. It confuses my receiver.

You don't typically don't want to switch output resolution to match the resolution of whatever your outputting on modern displays, but instead want to match the panel resolution and software scale the content. You're way too likely to confuse the monitor trying to match resolution. There's something to be said for matching frame rate, but there's even more dragons in that practically.

Truly modern TVs have much better scaling and frame interpolation than whatever your OS or media player can do.

What makes the TV software better than OS software?
