You can see our settings recommendations here. You should adjust 'Backlight' between night and day to avoid crushing details in the day or producing too bright an image at night. If you like some added sharpness then you can increase the 'Sharpness' slider but too high values will cause artifacts. Also adjust the 'Color Temperature' to your preference, and use a cooler value if you prefer more pop. If it is a low quality source then you should enable 'Reduce Signal Noise' and 'Reduce Block Noise'.
