Not all smart TVs will receive updates for long, and some don't have any specific policy.
No matter the price of a TV you buy, you likely consider it as a long-term investment. You thus expect it to receive support from the manufacturer for as long as possible.
In olden times, when you bought a TV, the only worry you had was it eventually breaking. But with smart TVs, there's also software to consider. Most modern TVs come with their own operating systems and apps, and need to be updated semi-regularly for the best performance and to patch security issues.
Unfortunately, there's no universal standard for how long you can expect a TV to get support for. It varies significantly by manufacturer, and the relevant information isn't always easy to find. But you're in luck, as we've done the tedious work of finding out.
If you have a Samsung TV from 2024 or later, Samsung will provide seven years of software updates for its Linux-based Tizen OS. This commitment, made in 2024, also applies to select models from 2023. That means if you have a Samsung TV from 2024, you can expect apps to work smoothly and firmware updates to roll out until at least 2031. Older models won't get major new versions of Tizen. They'll likely receive occasional maintenance or security firmware updates, though.
In early 2024, LG introduced the webOS Re:New program, which guarantees four years of webOS updates for TV models from 2022 onwards. These come with a one-year delay compared to the latest webOS release on the newest TV models.
