While Xbox One owners will be able to experience Gears of War 4 in HDR, it seems it will not be supported on Windows 10. This comes after NeoGAF user Coalition-PezRader, who is confirmed to be a Director of Community for The Coalition, confirmed this after a discussion was brought up by many on the forum. The user stated..
“Gears 4 has HDR on Xbox One S. It does not support it on PC. PC just started incorporating HDR support on cards recently and many monitors don’t have the functionality.
The PC version does support full 4K, Ultrawide, etc.”
PezRader did later state that it could be added after launch if the demand is there. Stating..
“I agree some PC users connect into HDR tvs but as of now we do not have support for it. We may incorporate it in a later update though if demand grows.”
