To watch 3D content on a TV, you can install a 3D-compatible TV and pair it with 3D glasses. A 3D-compatible TV has the necessary technology to display 3D images, and 3D glasses are required to view these images in 3D. According to a report by Statista, the global 3D TV market size was valued at approximately $10.5 billion in 2020 and is expected to grow at a CAGR of 5.5% from 2021 to 2027. This indicates a significant demand for 3D TVs and accessories, including 3D glasses.

A 3D-compatible TV typically features a 3D-ready display, which can be either an active-shutter or passive 3D technology. Active-shutter TVs use battery-powered glasses that open and close rapidly to alternate between the left and right eye images, while passive 3D TVs use polarized glasses that filter the image for each eye. Both types of TVs require a 3D source, such as a 3D Blu-ray player, streaming service, or a 3D game console, to deliver the 3D content.

3D glasses are essential for viewing 3D content on a 3D TV. These glasses come in various types, including active-shutter and passive 3D glasses. Active-shutter glasses are rechargeable and provide a more immersive experience, as they sync with the TV's refresh rate. Passive 3D glasses are more affordable and comfortable to wear for extended periods, but they may not provide the same level of immersion as active-shutter glasses.

In conclusion, to watch 3D content on a TV, you need a 3D-compatible TV and 3D glasses. The global 3D TV market is growing, indicating a high demand for 3D entertainment. Both active-shutter and passive 3D glasses are available to enhance the 3D viewing experience.
