Screen brightness dims when starting game
Here’s a rewritten version of your text, aiming for clarity and flow:
“My laptop’s screen consistently dims when plugged into power, regardless of the game I’m playing – specifically a model with an NVIDIA GTX 1070 running Windows 10. The issue seems to be related to adaptive brightness settings, as it initially resolved itself by disabling them. However, recently, this problem has reappeared, potentially triggered by a recent Windows or NVIDIA update. I've tried the standard workaround of minimizing and unplugging/replugging the laptop, but the screen remains dimmed. I’ve already confirmed that my display isn’t causing the issue, as adaptive brightness is currently disabled within the power settings. I’m seeking assistance in understanding why this is happening and finding a permanent solution.”
Here’s a rewritten version of the text:
I've been troubleshooting my computer's display behavior. When running games, the screen consistently dims to zero percent brightness, regardless of my power settings. I've tried several solutions including adjusting the built-in brightness slider (ranging from dim to full), creating new power plans with varying performance levels, and even setting the initial AC power state to different brightness percentages. I initially checked that the brightness was set at 75% on AC power, but this didn’t resolve the issue. The problem persists across all configurations.
then there could be a motherboard issue on power the the gpu on it very hard to tal what happens the other thing you could check if the settings is set on power saving mode ,or wait is someone that have similar laptop could have a clue .
I ran into the same thing with my new laptop. In addition to the screen dimming when running a full-screen game, it would also dim whenever I loaded a dark web page in a browser.
The culprit turned out to be Intel's new power saving options for the Intel integrated graphics. Yes I know you're using the Nvidia GPU. But on laptops with hybrid Intel + Nvidia graphics, the Intel integrated card is always on and always in control of the screen. The Nvidia GPU acts like a GPU. When a game finishes drawing a frame on the Nvidia GPU, the frame gets sent to the Intel integrated graphics, which displays it on the screen.
Open up the Windows menu in the bottom left (or hit the windows key) and search for Intel Graphics Control Panel. Once it's opened, click on Power. Then disable Power Saving Technology. That seems to be the one which auto-dims your screen even though you've disabled adaptive brightness in Windows. You may also want to disable display refresh rate switching.
