Our Verdict
Sony BRAVIA 9
TCL QM851G
The Sony BRAVIA 9 is better than the TCL QM851G. The Sony has better black uniformity and a better local dimming feature that gives it a higher contrast ratio, so it displays deeper blacks with less blooming. When it comes to accuracy, the Sony is a lot better in both SDR and HDR, so you get an image that is closer to the content creator's intent, regardless of the format of the content. The Sony has better image processing, so low-quality and low-resolution content looks better on it, and colors have less banding. Both TVs don’t have the widest viewing angle, but the Sony’s is wider, so the image doesn't degrade as quickly from the sides of the screen. On the other hand, the TCL gets brighter in HDR, so it can display some very bright highlights in HDR that the Sony can't.
