Short answer: the operating system (OS) is the software that runs your smart TV’s menus and apps. Samsung uses Tizen, LG uses webOS, Sony and TCL mainly use Google TV, Hisense mainly uses VIDAA, and some TVs use Roku TV or Fire TV. All run the big streaming apps, but UK app support, speed and update length differ.
| OS | Main brands | Strengths | Things to check |
|---|---|---|---|
| Tizen | Samsung | Fast, polished, wide app support | Adverts on home screen |
| webOS | LG | Easy to use, strong gaming features | Some menus busy with content |
| Google TV | Sony, TCL, some Philips & Hisense | Huge app store, Chromecast built in | Needs a Google account |
| VIDAA | Hisense | Quick and simple | Smaller app store |
| Roku TV | Some budget brands | Very simple, brand-neutral | Fewer advanced settings |
| Fire TV | Some Toshiba & others | Alexa built in, Amazon content | Amazon-focused home screen |
Which smart TV OS is best?
There is no single winner. If you want the most apps, Google TV is hard to beat. If you want a fast, simple interface, Tizen and webOS are both excellent. If you only use a few big apps, any mainstream OS will do.
What about UK apps?
BBC iPlayer, ITVX, Channel 4, 5, Netflix, Prime Video, Disney+ and YouTube are available on all mainstream platforms, but availability can depend on model year. See our smart TV apps guide and free TV apps UK.
Can I change my TV’s operating system?
No — the OS is built in. If you do not like it, or apps stop updating, add a streaming stick such as a Fire TV Stick, Roku or Google TV device.
FAQ
Is Tizen or webOS better?
Both are fast and easy to use. Choose based on the TV itself — picture quality matters more than the OS.
Is Google TV the same as Android TV?
Google TV is the newer interface built on Android TV, with a more content-focused home screen.
