Quick question (but slightly long post) regarding HDR for those using a 2019 OLED with a 20X0 series card. I've been playing some Game Pass games using the Xbox app and I've noticed that when I'm playing a game in SDR and I unlock an achievement, the screen will briefly switch to HDR during the achievement notification and then back to HDR once the notification is finished. Oddly, with some games I notice that they look WAY better during the brief moment it switches to HDR. So my question is--is there any way to force HDR even for games that are just in SDR? Not sure if it's something I'd want to do regularly but I thought it might be fun to to experiment with how games look in HDR mode. I know I can get everything to run in HDR if I play in windowed mode so I'm mostly curious to see if there's a way to force HDR while in full screen.
Incidentally, I can't confirm this but I could have sworn when I first connected my PC to my B9 that everything was playing in HDR10, even when it wasn't supposed to be. Unfortunately, I experienced a nasty glitch when I tried running Mass Effect Andromeda in Dolby Vision to see how it looked but all I got was a blank screen and then my PC started running everything in Dolby Vision so I had to reinstall all my drivers to fix it. Once I got everything running properly that's when I noticed that all my SDR games were running in SDR, just like they should. But again, I'm just wondering if there's a way to force HDR10.
