The all-new TVs are powered by hands-free voice control.
"With these latest additions, perhaps, a new benchmark will be established within the segment. We are confident that all three feature-rich televisions will generate a positive traction within the market and create new milestones for the brand," Mike Chen, General Manager, TCL India, said in a statement.
The 4K QLED TV C815 with built-in Subwoofer is available at a starting range of Rs 69,990 and comes in three variants: 55-inch (Rs 69,990), 65-inch (Rs 99,990) and 75-inch (Rs 1,49,990).

"The combined Dolby Vision and Dolby Atmos experience will allow TCL customers to experience their favorites as the producers and directors originally intended them to be."
