Smart TVs 101: What They Are and How to Choose

What is a smart TV?

A smart TV is a television with built‑in internet connectivity and apps. This means you can stream movies and shows, browse the web, and use services without needing a separate streaming box or computer. For many people, a smart TV serves as an all‑in‑one home entertainment hub.

How it works

Smart TVs run specialized software that lets you install apps, access streaming services, and sometimes integrate with voice assistants. They connect to your home Wi‑Fi (or ethernet) and pull content from the internet, often using built‑in processors to render apps and picture in real time.

How they differ from regular TVs

Regular TVs are primarily designed to display video from antennas, cable boxes, or external devices. Smart TVs include internet access and apps built into the set, removing or reducing the need for additional streaming devices. However, you can still connect external devices like streaming sticks or game consoles if you need more apps or performance.

Key features to look for

Operating system options

Different brands use different software stacks. Common options include Google TV/Android TV, Samsung Tizen, LG webOS, and Roku TV. The OS affects app availability, updates, and how you navigate menus.

App library and compatibility

A robust app store with your favorite streaming services is important. Check that the TV supports the apps you use most, and look for compatibility with casting and screen mirroring from phones and tablets.

Voice control and assistants

Many smart TVs include built‑in voice control (Google Assistant, Amazon Alexa, or the TV’s own assistant). Voice control can make searching for content, changing inputs, or adjusting volume quicker and hands‑free.

Connectivity and gaming features

Look for HDMI ports, USB inputs, Bluetooth, and built‑in Wi‑Fi. If you game, features like HDMI 2.1, VRR (variable refresh rate), ALLM (auto low latency mode), and high refresh rates can improve gameplay.

Privacy and updates

Smart TVs occasionally collect usage data. Check privacy settings, review what data is shared, and ensure the TV can receive firmware updates to stay secure and add features.

Buying tips

Screen and picture quality

Decide on panel type (LED/LCD, OLED, QLED) and resolution (4K is standard; 8K is available but with limited native content). HDR support (HDR10, Dolby Vision) can improve color and contrast. Consider brightness, local dimming, and viewing angles for room conditions.

Sound considerations

Many TVs have decent picture but average built‑in speakers. If you care about sound, consider a dedicated soundbar or home theater system, or check for better internal speakers and audio processing features.

Smart features and updates

Prioritize a TV with a well‑supported OS, a generous app library, and regular firmware updates. Ask about how long updates are provided and what privacy options are available.

Budget and value

Prices vary widely. Focus on the features you’ll actually use and pick a model that balances picture quality, app availability, and longevity with your budget.

Setup tips

Connect to Wi‑Fi and accounts

Power on the TV, connect to your home network, and sign in to your streaming services and app stores. Having everything tied to the same account makes switching between devices smoother.

Update firmware

Check for software updates after setup. Updates can improve performance, add features, and patch security issues.

Privacy settings

Review automatic data sharing options and disable or limit data collection if you’re concerned about privacy. Some TVs offer guest mode or limited data sharing as safer defaults.

Common concerns

Ads and clutter on the home screen

Many smart TVs show promoted content or preinstalled apps. You can usually customize the launcher and uninstall or hide unused apps.

Privacy concerns

Smart TVs can collect viewing data. Regularly review privacy settings and limit data sharing where possible. Be aware that some apps may request permissions you wouldn’t expect.

App compatibility and updates

App availability can change over time. If you rely on a specific service, confirm it remains available on the platform you choose.

Quick buying checklist

• Do you prefer OLED, QLED, or LED/LCD picture quality?
• Which OS do you prefer (Google TV, Samsung Tizen, LG webOS, Roku)?
• What apps are essential for you, and are they available on the TV’s app store?
• Do you plan to game on the TV? Are VRR/ALLM and HDMI 2.1 features available?
• How important are privacy settings and firmware update support to you?
• What’s your budget and screen size target?
• Do you need built‑in speakers strong enough for a small room, or will you pair a sound system?

Future trends

AI upscaling and processing

New TVs use advanced upscaling and image processing to improve older content and streaming quality, often leveraging on‑board AI.

Gaming features and consoles compatibility

More models support gaming features like higher refresh rates, VRR, and low‑latency modes, making TVs viable for console‑based gaming alongside streaming.

Voice assistants and cross‑device integration

Tighter integration across phones, speakers, and smart home devices is creating more seamless experiences for searching content and controlling displays.

Conclusion

Smart TVs offer built‑in streaming, apps, and internet connectivity that can simplify living room entertainment. By understanding the operating system, app availability, picture quality, and privacy options, you can choose a model that fits your viewing habits and space.
