1. Turn on the "Sharpness" adjustment button of the TV and adjust the sharpness value to "0". The higher the sharpness value, the sharper the edges of the picture, the more distorted the picture will be, and even noise will appear.
2. Set the TV's "Image Noise Reduction" to "Off". The image noise reduction function of the TV is similar to the "freckle removal" function of computer picture processing. The spots on the face are removed, but the details are also gone.
3. We can adjust the saturation of the picture according to our own preferences. If you like brighter colors, increase the saturation, and vice versa.
4. The contrast of the picture refers to the degree of layering of the image. If the contrast is strong, the layering of the picture will be reduced, the image will appear stiff, some image details will be lost, and the accompanying sound may interfere with the picture. If the contrast is low, it will also lead to a reduction in gradation, making it difficult to watch.
