NVIDIA releases hotfix 591.67 to address color banding and Control Panel issues

If your computer with an NVIDIA graphics card has some issues with colors, particularly in gradients in SDR mode, and the NVIDIA control panel won't let you turn off the tray icon, NVIDIA has a fix for you. The company has released a new hotfix driver to address bugs with color banding and bugs in its Control Panel.

The new hotfix driver is now available for download from the official website under version 591.67. It is based on the most recent driver, 591.59, which was released a few days ago with mostly bug fixes. Apparently, some bugs slid under the radar, and now, NVIDIA is catching up with a quick hotfix release.

Here is the changelog:

This hotfix addresses the following:

 

• Slight banding may be observed on gradients in SDR color mode [5720512]
• Colors are not applied correctly when using Digital Vibrance [5718365]
• Unable to deselect "Show Notification Tray Icon" from NVIDIA Control Panel [5622213]

NVIDIA usually releases new drivers to address bugs that require immediate attention and cannot wait for the next WHQL driver release. However, if you do not have those bugs on your system, you can skip the hotfix altogether and wait for the next driver release. If you want to update from an older driver to the latest one, download the hotfix instead, as it contains everything in the previous driver, 591.59 WHQL.

You can download NVIDIA Hotfix Driver 591.67 from the official NVIDIA support website. Release notes are available on the same page. The driver works on 64-bit Windows 10 and Windows 11 systems with NVIDIA GTX 16 Series and newer. The GTX 10 Series and GTX 900 Series are no longer supported, as NVIDIA recently dropped Pascal and Maxwell graphics card architectures.
