Why a cheap streaming stick beats the app built into your TV
Television manufacturers build screens. The software is an afterthought with a much shorter support life than the panel it runs on — which is why a cheap external box usually feels faster.
A television lasts a decade. The chip running its apps is specified to be cheap at manufacture, and the software stops receiving meaningful updates long before the screen shows any sign of age. That mismatch is the whole story.
What's actually going on
The processor is minimal. TV margins are thin and the silicon is sized for the apps as they existed at launch. Apps get heavier over time; the chip doesn't change.
Memory is tight. Constrained RAM is why switching between two apps reloads both from scratch rather than resuming.
Support windows are short. Manufacturers support a platform version for a few years, then move to the next one with new models. Your set keeps working, but stops getting optimisation — and eventually, apps start dropping support for the older platform entirely.
Codec support is frozen at manufacture. This one bites hardest. Video codecs improve, and decoding is done in hardware. A TV without AV1 decoding will never have it. If a service moves to a codec your set can't handle, you get a lower-quality fallback stream or nothing.
Why an external device fixes it
A streaming stick or box is a single-purpose device sold on the strength of its software, updated far more aggressively, and cheap enough to replace every few years. Replacing an inexpensive stick when it slows down is a different proposition to replacing a television.
The practical differences you'll notice: apps launch in a couple of seconds rather than fifteen; the interface responds immediately rather than lagging behind the remote; new apps and codecs arrive; and the search across services usually works properly.
Choosing one
The main platforms each have a character. Rather than ranking them, the questions that decide it:
- Does it run every app you use? Check the specific services you subscribe to, including smaller ones. This eliminates options faster than anything else.
- Does it support the formats you need? If you have an HDR set or a Dolby Atmos setup, confirm the device passes those through. Cheaper models often don't.
- How intrusive is the home screen? Some platforms fill it with promoted content. If that irritates you, it will irritate you daily.
- Does it fit your existing ecosystem? Casting from your phone, voice assistants you already use, a remote that controls your TV's volume.
- Wi-Fi or Ethernet? If your router is near the TV, a device with an Ethernet port is worth the small premium — see our piece on bitrate for why a stable connection matters more than a fast one.
Getting the most from it
Use the TV's game mode or PC mode if the picture feels laggy. Heavy image processing adds delay and often makes content look worse, not better.
Turn off motion smoothing. The setting that makes films look like video. It's on by default on most sets and named differently by every manufacturer.
Switch inputs automatically. HDMI-CEC lets the stick turn the TV on and select its own input. It's usually disabled by default and buried under a manufacturer-specific name.
Don't bother uninstalling the built-in apps. Most sets won't let you. Just stop using them.
When the built-in app is fine
On a set less than two or three years old from a manufacturer with a well-supported platform, the built-in apps are often perfectly good, and adding a box is unnecessary clutter. The case for an external device gets stronger the older the set is.
The simple test: time how long your most-used app takes from cold to playing something. Under five seconds, leave it alone. Over fifteen, an inexpensive stick will noticeably improve how often you actually use the thing.
