How to Choose a Streaming Device: The Complete Buying Guide

A streaming device is the cheapest way to make any TV smarter — or to make an old smart TV feel new. But the shelves are crowded, and the specifications look similar.

Here’s how to choose a streaming device step by step, so you get the right features for each TV without overspending. If you’re new to streaming, our beginner’s guide to how streaming works covers the basics first.

Step 1: Decide which TV it’s for

Start with the screen, because it determines what you need.

TV	What to prioritise
Main 4K HDR TV	4K, HDR formats your TV supports, Atmos, fast processor, Ethernet
Older 1080p TV	Smooth interface, good app support — 4K optional
Bedroom or kitchen TV	Compact stick, simple remote, low price
Projector	4K/HDR to match the projector, good audio output

Step 2: Choose a platform

The platform — the software and interface — affects how you find things to watch, which apps are available and how long the device is supported. The main ones are:

• Fire TV (Amazon) — tight Alexa integration, strong value, home screen promotes Amazon content.
• Roku — simple, app-grid interface, broad app selection, platform-neutral search.
• Apple TV (tvOS) — polished and fast, excellent for iPhone/iPad households, premium price.
• Google TV (Google) — content-first interface with personalised recommendations and Google Cast built in.

Each has strengths. We compare the most common pairs in Fire TV Stick vs Roku and Apple TV vs Google TV Streamer. Confused by the Google naming? See Android TV vs Google TV.

Platform questions to ask

1. Does it have all your apps? Check every service you use is available in your country.
2. Which ecosystem are you in? Apple, Google or Amazon smart home and phones work best with their own platforms.
3. How is search? Universal search across apps saves a lot of time.
4. How long will it be supported? Established platforms update devices for years.

Step 3: Match picture formats to your TV

Resolution

If you have (or plan to buy) a 4K TV, get a 4K device. The price gap between HD and 4K models is small.

HDR

Check which HDR formats your TV supports, then make sure the device supports them too:

• HDR10 — universal baseline.
• Dolby Vision — widely used by streaming services.
• HDR10+ — supported by some TVs, notably Samsung.
• HLG — used for live broadcasts.

Our guide to HDR10 vs Dolby Vision explains why this matters.

Frame-rate and dynamic-range matching

Look for match frame rate and match dynamic range settings. They let the device switch the TV into the correct mode for each title, avoiding judder and over-bright menus.

Step 4: Check audio support

For a soundbar or surround system, look for:

• Dolby Atmos support (delivered in Dolby Digital Plus by most services).
• Passthrough of surround formats to your soundbar or receiver.
• Bluetooth audio if you want to use wireless headphones.

See Dolby Atmos streaming for the full audio chain.

Step 5: Connectivity

Wi-Fi

Prefer Wi-Fi 6 (802.11ax) or newer for a busy home. Older Wi-Fi 5 devices are fine for HD and many 4K setups.

Ethernet

A wired connection is the most reliable for 4K. Some boxes have a built-in Ethernet port; many sticks need an adapter. Our guide to Wi-Fi vs Ethernet for streaming explains when it’s worth it.

HDMI

Make sure your TV has a free HDMI port that supports 4K and HDCP 2.2 for the device.

Step 6: Performance and storage

Cheaper sticks can feel sluggish, especially with many apps installed.

• Processor and memory: affect how fast menus and apps open.
• Storage: matters if you install lots of apps or games.
• Cooling: boxes stay cooler than sticks, which can throttle when hot.

A stick vs box comparison:

	Stick	Box
Price	Lower	Higher
Size	Hides behind TV	Sits on a shelf
Speed	Good to very good	Usually best
Ethernet	Often via adapter	Often built in
Storage	Limited	More

Step 7: The remote and voice control

You’ll use the remote every day, so it matters:

• Voice search (Alexa, Siri, Google Assistant or the platform’s own).
• TV controls — power, volume and input buttons via HDMI-CEC or IR.
• Remote finder — some remotes can beep when lost.
• Backlighting — handy in dark rooms.
• Shortcut buttons — often preset for particular services.

Step 8: Privacy and ads

All major platforms show recommendations; some also show ads on the home screen and collect viewing data. Review the privacy settings after setup — limit ad tracking and personalised ads where available. Our guide to smart TV privacy settings covers similar options.

Step 9: Budget

Budget	What you get
Entry level	HD or basic 4K stick, fine for secondary TVs
Mid-range	4K HDR stick with Dolby Vision, Atmos and Wi-Fi 6
Premium	Fast box with Ethernet, more storage, best formats and longest support

Spend more on the device for your main TV, and save on secondary rooms.

A quick decision guide

• iPhone/Mac household, main TV: Apple TV.
• Android phone / Google home devices: Google TV device.
• Alexa home, best value 4K: Fire TV.
• Want the simplest interface and neutral search: Roku.
• Budget bedroom TV: an entry-level stick from any platform you already use.

Common buying mistakes

• Buying an HD stick for a 4K TV to save a small amount.
• Ignoring HDR format support — check it matches your TV.
• Forgetting the HDMI port — older TVs may have only one 4K/HDCP 2.2 port.
• Powering a stick from the TV’s USB port, which can cause restarts.
• Choosing a platform that lacks a must-have app in your country.
• Overspending on a bedroom TV that only needs a basic stick.

After you buy

Setup takes about 15 minutes. For a walkthrough, see how to set up a Fire TV Stick — most platforms follow a very similar process. Then fine-tune your TV with our guide to TV picture settings for streaming.

The bottom line

Choose the platform that fits your phone and smart home, make sure the device supports your TV’s resolution and HDR formats, and prioritise speed and a wired option for your main screen. Everything else is personal preference.
