The primary reason why TVs struggle to display 3D content effectively is due to limitations in technology and viewer experience. Firstly, the technology required to produce and display 3D content is complex and expensive. According to a report by Statista, the global 3D TV market size was valued at approximately $3.3 billion in 2020, indicating the significant investment needed for 3D technology. Secondly, the viewer experience can be compromised due to issues like eye strain, motion sickness, and the need for specialized glasses. These factors contribute to the overall difficulty in achieving a seamless 3D viewing experience on standard TVs.
