But they will work with external displays! If you have a laptop with one of those hybrid Intel+NVIDIA GPU combinations, then HDR games don't work at all with the built-in display, they all report HDR support as N/A. Then it worked again after a few weeks when it updated.īut it might not be Firefox's fault, because Windows also seems to randomly turn color management off, or force it back to sRGB silently. Speaking of color: Firefox for a while just. Why? Because Microsoft employees test using Azure VMs, which. Windows Server 2022 can't activate its license unless it uses the UTC time zone. We're back to 8-bit RGB arrays in sRGB only as the only option. As in, Microsoft literally removed a wide swath of floating-point color support along with the wide-gamut scRGB color space. The Win UI SDK regressed from WPF and lost all wide-gamut or HDR support at the API level (which probably explains the above). It kinda-sorta works for some things, sometimes, but most apps that used to work with HDR back in Windows 10 just can't any more and are forced to use SDR with sRGB gamut only. Windows 11 almost but not entirely broke HDR. I just got a new laptop, and the amount of things that get shipped totally broken is just crazy. I've spent the last 3 days angrily submitting bug ticket after bug ticket, including one for Firefox.
