A smart TV and a UHD TV refer to different features of a television: a smart TV has built-in internet connectivity and apps, while a UHD (Ultra High Definition) TV refers to a screen resolution, typically 4K. In essence, one describes the TV's capabilities, and the other describes its display quality.
Here's a breakdown:
Smart TV:
- Functionality: A smart TV is a television that can connect to the internet. This allows you to stream video from services like Netflix, Hulu, Amazon Prime Video, and YouTube, directly on your TV. They often come with pre-installed apps and allow you to download more from an app store.
- Key Features:
- Built-in Wi-Fi or Ethernet port
- Operating system (e.g., Android TV, Roku TV, webOS)
- App store for downloading streaming services and other apps
- Voice control compatibility (e.g., Google Assistant, Alexa)
- Screen mirroring from smartphones or tablets
UHD (Ultra High Definition) TV:
- Screen Resolution: UHD refers to the resolution of the TV screen. The most common UHD resolution is 4K, which is 3840 x 2160 pixels. This means a 4K TV has four times the number of pixels as a Full HD (1920 x 1080) TV, resulting in a much sharper and more detailed picture.
- Key Features:
- Higher pixel density for sharper images.
- Support for HDR (High Dynamic Range) content for better contrast and color.
- Immersive viewing experience.
Analogy:
Think of it like this: "Smart" is like having a computer built into your TV, allowing it to access the internet. "UHD" is like having a higher-quality monitor for that computer, displaying sharper images.
Important Note: It's common for TVs to be both smart and UHD. Many (if not most) new TVs on the market combine these features. You can have a smart TV that is also UHD, or a smart TV that is standard HD. The two features are not mutually exclusive.
