Laptop screen becomes noticeably darker
Laptop: MSI Katana 17 HX
GPU: NVIDIA GeForce RTX 5060
OS: Windows 11
I'm experiencing an unusual screen-dimming issue when launching games through Steam.
Whenever I launch a game, the laptop's display becomes noticeably darker. When I Alt+Tab out of the game, the screen immediately returns to its normal brightness. However, as soon as I switch back to the game, the display becomes dark again.
Things I've already tried:
Disabling HDR.
Switching between fullscreen and borderless windowed mode.
Switching between NVIDIA GPU-only mode and MSHybrid mode.
Disabling the Steam Overlay.
Checking Intel Graphics Command Center for Display Power Saving Technology (the option is unavailable).
Checking Windows adaptive brightness settings (the option is unavailable).
Checking MSI Center (no Gaming Mode available).
Checking NVIDIA Control Panel and switching to Reference mode.
Checking NVIDIA Game Filters (no active filters).
Checking Windows Color Management (no ICC profiles listed).
None of these changes fixed the issue.
One additional observation: screenshots taken in affected games also appear dark when viewed outside the game.
Has anyone experienced something similar, particularly on an MSI laptop? Could this be related to gamma correction, DirectX, NVIDIA drivers, or Windows display handling?
I'm trying to find a solution that fixes the issue globally rather than having to adjust every game's brightness individually.
