Brightness reduction, HDR and image capture

 



 

The OLED panel is not as bright as the rear monitor, including the FALD and Mini LED options. The PA32DC achieves a peak brightness of 500 nits in HDR (10% APL/patch size), or around 250 nits in full screen (100% APL). Like all OLED panels, the panel relies on "automatic brightness control" (ABL) to control the distribution of power across the panel, allowing maximum brightness for small areas, but meaning your maximum brightness will be lower for larger areas. If you would like to know more about ABL and how it works, check out our recent article here. If you want to use the display without needing ABL, Asus proart offers a nice "Even Brightness" mode in the OSD that limits the brightness to 250 nits to prevent ABL dimming. For creating and editing SDR content, the PA32DC is an excellent choice and the power of the OLED panel gives you exceptional image quality. 

The limited optimum brightness means that using the display for creating and recording HDR content is a bit more complicated as there are different brightness and HDR gamut values ​​to consider. On the plus side, you will get the amazing contrast ratio of OLED, every pixel resolution to avoid flare and halos, and excellent pictures in dark and light-controlled environments, which is how HDR content should be viewed. It can handle well-known content up to 500 nits well, and you can also set the PQ mode to hard clipping, following the standard process well to the highest brightness before reducing the main points on the surface.Brightness, HDR and Image retention mitigation
