Let's say I have a display which is HDR-capable with a max brightness of 1000 nits in HDR mode, and a max brightness of only 400 nits in SDR mode. I have the display connected to a HDR-capable Windows machine. As an example of SDR content, I've set the Windows desktop background to white color. Since the Windows desktop isn't HDR content, the desktop white appears as 400 nits on the display. Is it possible to force the display to show it at 1000 nits instead?
What I've tried: Some web searches pulled up this hardware being used to show content as HDR, but I haven't been able to test this. Or, there is the option to choose HDR under color settings in the NVIDA control panel (not relevant for my computer since my graphic card is Intel, and the Intel graphics command center doesn't seem to have the option to choose HDR).
