As of my knowledge cutoff of April 2023, the cheapest 85-inch TV available in India is the Realme Smart TV 4K (SLED) 85-inch, priced at around INR 1,49,998 to INR 1,99,999. However, it's important to note that this is still a high-end TV with advanced features like a 4K resolution, HDR support, and a smart TV interface with access to streaming apps.
If you're looking for a budget-friendly option, you may want to consider a smaller screen size or a non-4K resolution. Some brands like Power Guard, TCL, and Vu offer affordable TVs in larger screen sizes, but they may not have the same level of features and picture quality as the high-end models.
