I use HDR for all my gaming. In order to use VR in MSFS
#1 -I must first disable HDR in the windows.
#2- Start sim disable HDR, (note: sometimes if not done in order a second reboot of the sim is required).
I then must repeat this process to undo it.
I hope there can be a better solution such as allowing me to keep all my HDR settings active for 2D. While the sim turns off HDR for VR proper use.
Cheers
Stay safe,
