U2713H does not have the HDR/EDR certification due to its age but it is true wide gamut 10-bit display with hardware LUT calibrated by X-Rite i1 Display Pro Monitor Calibration Device. It is not fair to compare Affinity Photo with the professional software like Photoshop therefore I mentioned only the "NEC 10 bit Color Depth Demo application" but I also have "Adobe Photoshop Version: 21.0.2 20191122.r.57". Photoshop has a "30 Bit Display" setting unter "Edit" > "Preferences" > "Performance" > "Graphics Processor Settings" section > "Advanced Settings..." button (look at the screenshot in attachment). 10 bit gradients like this one https://github.com/jursonovicst/gradient are smooth in Photoshop with this setting. In Affinity I do not see any difference between 8 and 10 bit gradients just like in Photoshop if "30 Bit Display setting" is disabled. https://affinityspotlight.com/article/biggest-ever-affinity-updates-bring-unrivalled-speed-power-and-extensive-new-features/ provides only marketing information unfortunately so I still do not understand why the gradients are not smooth. Is it possible that Affinity does not support higher bit depth on Windows? Does Affinity Photo have an equivalent of the "30 Bit Display" setting in Photoshop?

Hello! NVIDIA provides 30-bit color support for GeForce users since July 2019 so it became widely available now (https://www.nvidia.com/en-us/geforce/news/studio-driver) NEC 10 bit Color Depth Demo application (https://www.necdisplay.com/documents/Software/NEC_10_bit_video_Windows_demo.zip) demonstates that my system also supports higher bit depth (Win10 with NVIDIA GTX 1070 and DELL U2713H) However it looks like Affinity Photo is not capable to display smooth 10-bit gradients. Am I missing some setting? And if not - do you have any roadmap to support higher color depth or sell some additional 30-bit extensions? Thank you! P.S.: Few older posts on the the same topic:
