Not so fast. With a 100% APL (all white background) the S20 Ultra can only hit 500 nits in manual mode. That means the ambient light sensor decides when it can give you another 500 nits for a total of 1,011 nits. The 12 Pro Max can hit 825 nits at anytime. This is more with software than hardware.The Galaxy S20 Ultra has a Record Peak Brightness of 1,342 nits, which is 10% higher than on the Galaxy S10. See the Brightness and Contrast, the High Ambient Light and the Screen Reflections sections for the measurements and details. The Galaxy S20 Ultra can play 4K High Dynamic Range content made for 4K UHD TVs. 👁👅👁
