The most important ports a Smart TV should have

To maximize the features of Smart TV, users need to understand popular connection ports such as HDMI, USB, LAN, Optical and ARC - each type has its own role in the visual and audio experience.

HDMI port – the “backbone” of image connection

HDMI (High-Definition Multimedia Interface) is the most popular connection port on Smart TVs today. It allows simultaneous transmission of high-quality images and sound through just one cable.

Users can connect the TV to an HD player, game console, laptop, Android box or Apple TV. When choosing to buy, you should prioritize TV models with 2 to 3 HDMI ports, especially HDMI 2.1 standard to support 4K/8K resolution and high refresh rate.

USB port – convenient for entertainment and storage

The USB port on Smart TVs allows users to easily connect hard drives, USBs, or peripherals such as mice and keyboards. This is a convenient way to play music, watch movies, or display photos from storage devices. Some high-end TVs also support USB 3.0, which allows for faster and more stable data transfer.

LAN (Ethernet) port – more stable than Wi-Fi

LAN (Ethernet) port is the ideal choice if you want a more stable network connection than Wi-Fi. In cases of watching 4K movies or playing online games, connecting directly to the modem or router via LAN port will ensure high network speed and less interruption.

Optical port – high quality digital sound

Optical port, also known as Toslink, is a port that transmits digital audio from the TV to speakers or sound systems. The advantage of this type of port is that it provides clear, noise-free sound quality. Optical is especially suitable for sound systems that do not support HDMI ARC.

HDMI ARC/eARC port – optimized sound

HDMI ARC (Audio Return Channel) is a special feature of HDMI that allows audio to be transmitted from the TV to the speaker without the need for a separate cable. Users can easily connect to a soundbar or receiver, helping to reduce the number of connecting wires.

The upgraded eARC version supports premium surround sound like Dolby Atmos and DTS:X, providing a more immersive cinematic experience.

AV, Component, and 3.5mm Jack ports – for older devices

Some Smart TVs still retain traditional connection ports such as AV (3 colors: red, white, yellow), Component (5 colors) and 3.5mm headphone jack. These ports are very useful for users who own old devices such as DVD players or retro game consoles, helping to save on replacement costs.

When buying a Smart TV, don’t just look at the size or resolution – check the ports. A TV with HDMI, USB, LAN, Optical and ARC will help you get the most out of your peripherals and enhance your home entertainment experience.
