Ask HN: What's the best hackable smart TV?

286 points by xrd 7 days ago


I want to get a second TV which will more or less be a second monitor for my System76 laptop which is plugged into a bunch of music equipment, like a korg midi keyboard, and a novation drum pad, all of which work great with linux.

I want to buy this TV used. I'm seeing a bunch of Samsung, LG, RCA, Sony, etc on Facebook Marketplace. What a cesspool Facebook has become, right?

Any suggestions on the best brand or even model for that kind of thing? I don't really want to battle with a bunch of shit that tries to coerce me to install another app from a streaming provider slash gambling entrypoint.

I imagine mostly it will just need HDMI to work, and all the TVs will support that. But, I thought maybe there would be a fun brand that offers interesting other options.

Do recommend the LG C series (C5 or C4 are new or the C1 series if you want a deal on classifieds - same hardware as the higher end models but needs a firmware bit flip). The OS is very rootable and it makes a great TV that doubles as a monitor. Supports free sync / g-sync. OLED is nice at this scale.

Text is very readable, refresh rate is good. It uses the same panels as the fancier G series in the larger sizes. One can root the firmware to make it go brighter. (Though this is screen works well in medium or dimly lit rooms. It does not shine in very bright rooms).

Plenty of YouTube videos singing the C series praises as a TV / Monitor.[1] LG webOS is also trivial/friendly to root in developer mode and network control of the tv is a nice to have.

Would avoid Samsung. I love the matte on the Frame and the design of the Serif but the OS is frustrating / impractical to root.

For "fun and interesting" consider an LG WebOS TV. Many can be rooted[1] which allows installing a homebrew channel[2] of unauthorized apps or writing your own.

I initially did it for Jellyfin before they made it into the official app store, but the Moonlight game streaming app has unlocked many hours of entertainment.

I have Sony Bravia TV that has Android TV so I went looking for the docs to confirm you can enable developer mode, access adb, and sideload apps. While looking at the docs I discovered I can load HTML5 apps from USB! I never knew that but I'm going to do some experimentation in the near future.

Craigslist an older 1080p TV. People are getting rid of old "dumb" TV's, and sometimes you can get them free. I see seemingly undamaged LCD TV's out by garbage bins all the time. I sourced one such a TV for my wife for $100 a few years ago to use as a monitor - works great. No apps or anything - dumb as they come.

I bought a Hisense model from Costco and set it to "store mode".

For all practical purposes, it is just a dumb HDMI display attached to my computer.

Why does it need to be a TV? Why not a monitor? I don’t know why we even differentiate between the two of them these days… basically the only difference is that a TV might have an IR receiver for a remote.

I’d go with a basic monitor and factor out the “smart TV” into whatever device you prefer – Apple TV, Chromecast, Firestick, any SBC with Kodi loaded onto it… an Xbox… why couple the smart features to the display?

Best hackable smart TV should be a Linux box connected to a monitor or to a "smart" TV via HDMI without Internet access. The best thing about this setup is that you can stream Youtube ad-free though clients like VacuumTube. You can also open a browser and head straight to the high seas. Plus countless other things that are arbitrarily restricted or made difficult in locked down environments, all without your viewing habits being sent to the mothership, data brokers, and possibly the government.

The main downside is that there is currently no great "ten foot" UI for this use case on Linux. But the KDE Bigscreen project is being revived and could offer a definitive solution for free TVs.

What does hackable mean in this context, and what's the downside of any old smart TV not connected to the internet and the input left on your laptop, where you'd never see anything having to with the manufacturer's app OS?

colangelod - 3 days ago

If you just want it for the HDMI input to use as an aux screen for what ever computer your running than anything with an HDMI input in the size range you want should work. I run all the TV's in my house like this; connected to mac mini's instead of futzing with the onboard software mostly because I despise typing one letter at a time with a tv remote.

Honestly all the onboard TV OS stuff I have interacted with in the last decade has been more or less terrible and I wouldn't even consider it when buying a TV especially one that is just going to be a screen. All of the recent installs Ive dealt with (family and friend support) has revealed a ton of pay-to-play features (Samsung frame tv's cough cough). I applaud you for wanting something neat but I cant say Ive come across anything Ive ever actually wanted to use beyond "select input -> HDMI1"...

Any smart TV where some hacker could install its own build of the OS ? Kinda like LineageOS for smart TV ?

Im using a 43 inch samsung tv as a monitor. It works fine as long as you never conect it to internet.

Chroma 4:4:4 support is supposed to be important for viewing text.

I compiled/ported the mario64 port to the LG TV quite easily, so I would say that LGTV is the best for that.

th0rine - 3 days ago

Older LG sets (tested on C9 OLED) had security vulnerabilities you could use to root your TV and then do "??????" you wanted with them. WebOS as a platform causes a lot of unproductive discussion surrounding it's ecosystem and such but if you want to "hack" or actually have a shell on your TV it's great for that to do anything else you want. Personal favorites include changing the default screensaver behavior to the bouncing DVD logo, running Chocolate Doom, and a port of Space Cadet pinball natively. More info here - https://rootmy.tv/

Dpeends what your after, but a second hand NEC multisync, which has an ST slot https://www.sharpnecdisplays.eu/p/download/cp/Products/Optio...

but that might be a bit too basic. because its basically a monitor with 100% duty cycle and a PC.

What you are looking for is a digital signage display and some android tv box

I wish there were more modular tvs like this https://m.youtube.com/watch?v=-epPf7D8oMk

I think Tizen lets you write your own apps. I know I installed Emby on one of the very cheap smart tvs recently and had to install it via developer mode and pull in the package by typing the IP of my laptop into the TV (maybe vice versa).

I didn't write the code but it seemed like you can get a development account from Tizen and write your own apps.

To be clear, Tizen is not a brand of TV, it's the name of the OS. It's fairly common on various no-name hardware brand, check it out.

I use a NEC OPS module tv I got on facebook marketplace as a digital signage monitor. Best purchase I've made yet, though I will admit the feet for it being 200 dollars was quite a shock (they're made out of steel and about 2 feet long each so it makes sense) completely dumb tv, takes all inputs from HDMI to component and has features like auto-sleep without any real smarts inside. I love it.

phantomathkg - 2 days ago

As ex-Smart TV app developer, I would stay with Sony's Android TV. Reason being

- Samsung Tizen is sluggish. - LG webOS is fiddly and don't feel it gets enough attention and care from LG. - Other brand is just slow. - On hackability, Android is far easier to handle than any other brand.

Mind you Sony has a few line and some run Android, some run something else.

I ditched the whole smart TV years ago. I was never a fan of the slow, ad-ridden software, and later found that enormous packets were being sent when I monitored the DNS at the network level despite the TV being 'turned off'. Instead, I got a non-smart TV (you can find old Sony TVs) and attached a TV box or direct hdmi to an old laptop instead, far smoother and better at all levels.

Side question: what TV is best for integration into home assistant from experienced HA users...

Xelbair - 3 days ago

Any that you can put in store mode, and run all smart features off separate device.

Otherwise it will run out of updates fast, services will stop working and only way to fix that is to buy.. a separate device.

This also let's you make search easier as you can just look at the panel itself when comparing.

I have a 10yr old Insignia 1080p TV. One of the 3 HDMI inputs is a Roku stick and I have Home Assistant watch for it and load the Jellyfin app whenever the TV gets turned on. Works most of the time and it's nice to avoid the Roku ads.

Is there a reason folks don't just use a TV tuner attached to a rather large desktop monitor? (On the desktop? Linux.)

palata - 2 days ago

I actually would like to have a hackable AOSP device with some kind of open source chromecast (because chromecast comes with the Google Services, I guess?).

Then I can plug that into any dumb TV/beamer I find.

psyclobe - 2 days ago

Stay away from lg, anything with android is a good choice; custom launchers to remove the gif damn Home Screen. I stick to Sonys my one of tv is so terrible will never buy one again.

I've generally heard LG is the place to start looking, only because they are the inheritors of the hidden jewel that was/is webOS.

finnlab - 3 days ago

I can recommend The LG B2, great panel, great price. The software sucks however but you won't find OLED much cheaper.

A dumb TV with an x86 HTPC attached to the back via VESA bracket. Sceptre dumb TVs from the Wal-Mart web site are your cheat code.

palata - 2 days ago

I always wonder if there is a kind of AOSP-based alternative to Android for TV?

MisterTea - 3 days ago

I mentioned in another post here that I opened a friends TV and found just 3 PCB's: Power, LCD interface, and Video SoC. The video SoC is an Arm SoC for TVs that runs Android complete with video input switching matrix and processing. The SoC board had Wifi, bluetooth, Ethernet and USB. It's all there.

My dream is to hack that SoC to boot whatever OS. Though good luck getting the datasheets...

A dumb TV like a Sceptre with a smart hackable device.

A Vizio without accepting the agreement is a fine hdmi TV.

You could score some insane screens from recycling centers, but at least in Finland, its fucking illegal to repurpose (steal) "electronic waste" However, depending where you're located, all that stuff might go to somewhere else than smasher and smelter, so please check such places around you! Good example is https://www.youtube.com/watch?v=WbqOvBHVpbw ,he found old tobacco ad display (ips!) for cheap!

I kind of hate smart TVs -- my family got a Samsung one that got feature obsoleted in months , but I needed a cctv kiosk -- I bought a fire stick and the cheapest +speakers monitor on amazon with an HDMI port and USB power, was pleasantly surprised; 4k, tiny, performant, adb access isn't fucked up, and you can change the home screen.

By the end of the day it's just an android device with an HDMI out, and that's exactly what I wanted.

You probably want a computer monitor rather than a TV; monitors will prioritize latency which is important for music production.
