Hi, I'm suffering a problem for a few months. I can't remember the exact date it started but is really annoying. I usually use custom resolutions for gaming. And I usually prefer exclusive fullscreen mode because a lot of games have better framepacing in this mode. The problem is that downsampled resolutions show crushed blacks when used in games in exclusive fullscreen mode. This problem doesn't happen in desktop if I use a higher custom resolution, and doesn't happen if I play the game in borderless mode after increasing the desktop resolution. For example, in my 1080p TV, using 4K downsampled in desktop, colors and contrast is perfect. But if I start a game at 4K in exclusive mode, I lost a lot of shadow detail. It's like contrast values are wrong. Ideas? Thank you!
