TCL will shortly launch the 115-inch QM89 4K QD-Mini LED Smart TV in the US. Like the European X955 Max, the model offers full array local dimming with over 20,000 dimming zones. Other features include a built-in 6.2.2 speaker system, Game Accelerator, and AMD FreeSync Premium Pro support.https://www.notebookcheck.net/TCL-reveals-new-massive-115-inch-QM89-TV-pricing.838101.0.html
Imagine the power usage, at least 3kW I'd say and 6kW if it were 8K.
