Wifi TV sets are television sets equipped with WiFi, a wireless connection port. WiFi port enables a TV to communicate with various electronic devices (WiFi internet router, PC, gaming console, blu-ray player) without being physically connected to them. For such connection to work, electronic devices that are connected to television must support WiFi communication too.
One benefit is the possibility to connect your TV with computer, gaming console, media player without using an Ethernet cable. These can be very practical, especially if you have more than one device that you want to connect.
Other, much bigger benefit is that most WiFi TVs are internet ready TVs. This means that you can connect your TV to the internet. In this manner you get access to different internet services (internet applications). A selection of internet services depends on TV manufacturer. Majority of them offer internet browsing, video and music on demand, access to Youtube, Facebook and similar social networking application, online photo galleries sharing, Skype, weather and sport information, etc.
Different TV manufacturers have different user interfaces to interact with the internet applications. All of them have some kind of icon styled menu interface, easily operated with remote control. Some brands like Visio include remote control with keyboard so you can interact with applications like Twitter and Facebook. Others offer a possibility to connect a standard USB computer keyboard to TV set.
