NVIDIA Driver 616.56 Flickers on 8-Bit Monitors, 10-Bit Fix Works

NVIDIA Game Ready Driver 616.56 introduces a display flickering bug that affects users with 8-bit monitors. This issue matters because it disrupts visual stability for gamers and desktop users who rely on standard color depth settings. The problem forces a choice between accepting visual noise or changing monitor configuration.

Switching to 10-bit color depth resolves the flickering issue

The driver version 616.56 triggers flickering specifically on displays running in 8-bit color mode. User @renan_maniero reported the issue and confirmed the behavior across multiple test setups. NVIDIA staff have acknowledged the bug and are currently testing a fix for the problem.

Switching the monitor output to 10-bit color depth resolves the flickering almost immediately. Enabling the Adaptive Color Management (ACM) feature in Windows also stops the visual artifacts. These workarounds provide immediate relief while the permanent driver patch remains in development.

Users whose monitors do not support 10-bit color depth should consider rolling back to the previous driver version. NVIDIA is actively working on a solution that will allow 8-bit displays to function without flickering. We looked at the last Game Ready Driver update while tracking these stability themes.

The flickering issue is confirmed to be specific to 8-bit mode in the current driver release. A permanent fix is under testing by NVIDIA engineers. Users can apply the 10-bit or ACM workarounds until the official patch ships.
