Regarding wrong black levels/brightness, when playing back Blu-Ray discs in PowerDVD 21 software.įor the video playback, PowerDVD would decode the video to a bitstream, it will not touch the color space's dynamic range that the video is encoded natively, and does not have the option to adjust the color space's dynamic range (16-235 or 0~255) for display when playing the video.
Is there a reason why there are no real options to configure video playback in the Radeon Software? But to stress, it does not appear to be PowerDVD at fault - it works correctly with an Nvidia 3060Ti swapped in.Ĭan anyone else confirm this behaviour with hardware accelerated video decoding (DXVA) using Navi? 62 version), Radeon Software (latest 21.12.1 driver) on Windows 10 Pro 21H1. The specific software versions are: PowerDVD 21 (latest. There is no option to force full dynamic range for video playback in the Radeon Software (like there is in the equivalent Nvidia control panel) - there are almost no options for video playback at all apart from the basic profiles that do no expose what settings are being applied. Using an Nvidia GPU, or by forcing video playback using software decoding and bypassing DXVA, fixes the issue and displays correct black levels. black levels are elevated and appear grey.īy testing different combinations of playback software and GPU the problem does appear to be specifically when DXVA is being used on the Radeon - the output is limited range despite the display pixel format being configured in the Radeon Software for RGB 4:4:4 PC Full Range.
When playing commercial Blu-ray discs using PowerDVD 21 on a system using a RX 6800 XT GPU, the video always plays with limited dynamic range - i.e.
