Is there any way to use a game's built-in HDR with borderless full screen or windowed full screen?

Hi there,

I've got an MEG 342C (3440x1440), and I've tried playing a couple of games today (Immortals of Aveum and Lords of the Fallen, the new one) and enabling the in-game HDR settings with HDR enabled in Windows, I use this screen with HDR enabled pretty much exclusively, as everything looks better. But when I set the in-game HDR to 'on', it goes back to full screen mode, but then the full screen mode is squashed into a small window with two black bars down either side, like watching an old 4:3 aspect ratio TV show on a new TV.

Is there any way to fix this? Either to allow a game's built-in HDR to be used in borderless full screen, or windowed full screen mode, or to make exclusive full screen the correct size, and not squashed into a Window.

Thank you.

4. The way your screen is behaving when you switch to HDR sounds v odd - will need more info from you to help out but @Varys is on the right track there potentially. In the NV control panel go to "adjust desktop size and position" and tell us what radio button is selected in the Scaling tab, and is scaling being performed on GPU or display in the dropdown?
Also, your monitor's own OSD/settings might have options for aspect ratio and scaling behaviour, so you may need to look into that too....

This is what my Nvidia control panel is set to at the moment:
