OLED and high-end TV panel technologies provide vibrant colors, sharp pictures, and extreme brightness. Yet they're also expensive, with prices easily dipping into the multiple thousands depending on the size of the TV. For example, TCL's QM7K series comes in six sizes between 55 and 115 inches with QD-Mini LED technology, 4K UHD resolutions with HDR, and 120-144Hz refresh rates. This model comes with Dolby Vision and Dolby Atmos, a 120Hz refresh rate, HDR 10+ support and Alexa built-in with Amazon's Fire TV smart streaming platform. The point is, there are quite a few options out there that are less expensive but still plenty nice enough for a home theater setup.
