Windows 10: Windows 10 version 1903: banding on gradients issue

Microsoft released KB4501375 for Windows 10 version 1903 recently to fix a number of issues. One of the fixed issues affected calibration loaders and applications like the popular F.Lux program that make use of the SetDeviceGammaRamp API.

The changelog confirms that Microsoft fixed the issue in KB4501375:

Addresses an issue that may cause Night light, Color Management profiles, or gamma correction to stop working after shutting down a device.
​

It appears, however, that Microsoft introduces a new bug that causes banding on gradients even when calibration is not active. Any program or game that loads an ICC profile may be affected by the issue.

The issue is that severe that Eizo published a support page on the company website in which it recommends to avoid PCs installed with Windows 10 version 1903 at the time.

The company notes that tones are not displayed correctly, and that the issue affects all monitors and all graphics boards.

We highly recommend not using a PC installed with Microsoft Windows 10 (1903) for the time being, especially for diagnostic imaging or graphics editing which requires tone accuracy.
​

Windows 10 version 1903 users may look at gradients, e.g. on this monitor test page, to find out if they are affected by the issue. The gradient should be smooth; a device is affected by the bug if stripes are noticeable when you look at the gradient.

A workaround




A workaround has been published, e.g. on the DisplayCal forum, that suggests to disable the Calibration Loader task in the Windows Task Scheduler.

1. Open the Start menu, type Task Scheduler, and select the item from the list of search results to open the Task Scheduler.
2. Navigate to Microsoft > Windows > WindowsColorSystem
3. Double-click on the Calibration Loader task.
4. Switch to the Triggers tab.
5. Double-click on "At log on.
6. Remove the checkmark from "Enabled".
7. Repeat the process for "On connection to user session" to disable the trigger as well.
8. Log out and back on again.

Note that it is required to make the change again if the associated profile is changed.

Microsoft released the final version of Windows 10 version 1903 at the end of May 2019 to the public.

Banding issues on 6300

Hi,

are there any known issues with the display of the Nokia 6300, especially concerning colour gradients and "banding" effect?

On my 6300 which I received a few days ago (production date 08/2007, FW 4.71), gradients do not appear to be as smooth as expected and show a slight banding effect. This can best be seen when using the original "Noir" theme, both in active standby and on the
default background..

Best wishes,

Karsten

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
