I absolutely hate "smart" TVs! You can't even buy a quality "dumb" panel anymore. I can't convince the rest of my family and friends that the only things those smarts bring are built-in obsolescence, ads, and privacy issues.
I make it a point to NEVER connect my new 2022 LG C2 to the Internet, as any possible improvements from firmware updates will be overshadowed by garbage like ads in the UI, removal of existing features (warning: reddit link), privacy violations, possible attack vectors, non-existent security, and constant data breaches of the manufacturers that threaten to expose every bit of personal data that they suck up. Not to mention increased sluggishness after tons of unwanted "improvements" are stuffed into it over the years, as the chipset ages and can no longer cope.
I'd much rather spend a tenth of the price of my TV on a streaming box (Roku, Shield TV, etc.) and replace those after similar things happen to them in a few years. For example, the display of my OG 32-inch Sony Google TV from 2010 ($500) still works fine, but the OS has long been abandoned by both Sony and Google, and since 2015-16 even the basic things like YouTube and Chrome apps don't work anymore. Thank goodness I can set the HDMI port as default start-up, so I don't ever need to see the TV's native UI, and a new Roku Streaming Stick ($45) does just fine on this 720p panel. Plus, I'm not locked into the Roku ecosystem. If they begin (continue?) enshitifying their products, there are tons of other options available at similar price.
Most people don't replace their TVs every couple of years. Hell, my decade old 60-inch Sharp Aquos 1080p LCD TV that I bought for $2200 back in 2011 still works fine, and I only had to replace the streamer that's been driving it twice during all this time. Sony Google TV Box -> Nvidia Shield TV 2015 -> Nvidia Shield TV 2019. I plan to keep it in my basement until it dies completely before replacing it. The Shield TV goes to the LG C2 so that I never have to see LG's craptastic UI.
Sorry, just felt the need to vent. Would be very interested in reading community's opinions on this topic.
I have some practical annoyances, most surrounding multiple remotes and the clunkiness of it. I have two TVs in my house: a Samsung smart TV from 2019 and a Hisense Google TV I purchased earlier this year. The Google interface is not the most responsive, but it packs in all of the stuff I would want. Android is the most supported platform for apps. Samsung's OS has good app support, but open source projects and more niche apps aren't there. I think there is a nebula app now, but for a while there wasn't, for instance. So, I bought one of the Chromecast with Google TV sticks to bridge the gap. It works well most of the time, but unlike the Hisense, it doesn't support airplay. So if someone airplays, you get kicked back to the native OS and have to use the native remote. It's possible to configure the Chromecast to use the native remote, except the home button doesn't map, it is the home menu for the native OS. So it's just kinda clunky. I do think newer Google tvs with airplay built in (varies by brand) are going in the right direction here. If you're concerned about privacy, they're still gonna be a nightmare though.
I have a Logitech Harmony Ultimate remote with Hub. It was the best thing ever for me, because in my living room setup I have the TV, A/V receiver, Nvidia Shield TV for streaming, and an Xbox Series X for my kids and occasional BR/DVD movies. With programmable activity buttons, a single tap on the remote turns on the appropriate devices, switches them to the correct inputs, and provides appropriate controls. Tap another activity, and it turns on devices that are required, turns off the ones not in use, and switches controls to the proper device.
Unfortunately Logitech discontinued the Harmony line. It's only a matter of time before they take down the servers that host device databases and allow you to reprogram the remotes. I've been looking into replacements, but there aren't many that have feature parity with Harmony.
Seems the best way is with IR blasters and learning remotes. There is software for PCs/Macs that will let you capture the IR remote functions, then you can assign that to a "smart/learning" remote to relay those signals. Not nearly as easy as the Logitech setup, and I'm dreading the day the Harmony remotes stop working.
