Dell Wyse ThinOS Version 8.6 and ThinOS Lite 2.6 Operating System Release Notes

PDF

Disable DisplayPort audio

By default, the DisplayPort audio is disabled on Wyse 3040 thin client from this release onwards. This is the factory default setting. You can enable the audio by using the GUI option or the INI parameter.

If you upgrade ThinOS version from 8.5 to 8.6, the DP audio is not disabled by default. This is because the DP audio is enabled by default on thin client running ThinOS version 8.5. You must reset the thin client running ThinOS version 8.6 to factory default settings to load the default setting.

However, thin clients shipped with the latest version of ThinOS are already configured with the default settings.

On Wyse 3040 thin client, if you set the display resolution higher than 1920 X 1080, and enable the DisplayPort audio, a black screen is displayed for 10 seconds after the system reboot.

Do not enable the DisplayPort audio.
