Remote Control Default Settings (6-bit Color Depth) Not Saved in ITCM 14.6.0

Products

• CA Client Automation - IT Client Manager

Issue/Introduction

After upgrading to ITCM 14.6.0, users are unable to save specific Remote Control settings as defaults through the Viewer GUI. Specifically, when selecting Experience > Color Reduction > TV Color: 6 bits/pixel and clicking "Save as Defaults," the setting is not persisted. Subsequent connections revert to the previous or system-default color depth.

Impact: Higher color depths on certain network or hardware configurations can cause the target computer's display to turn black for several seconds, leading to user confusion or accidental shutdowns.

Environment

Product: CA Client Automation / IT Client Manager
Version: 14.6.0, 14.5 CU7 
Component: Remote Control Viewer

Resolution

To force the 6-bit color depth default, the configuration must be set manually via the command line for each affected user profile on the machine where the Remote Control Viewer or DSM Explorer is hosted.

1. Log in to the machine as the user who requires the setting.
2. Open a Command Prompt.
3. Run the following command:

   ccnfcmda -cmd setParameterAttribute -ps itrm/rc/Viewer/General -pn colordepth -an count -v 9 -u CURRENT_USER

4. (Optional) Verify the setting has been applied by running:

   ccnfcmda -cmd getParameterValue -ps itrm/rc/Viewer/General -pn colordepth

5. Restart the Remote Control Viewer or DSM Explorer. The "TV Color: 6 bits/pixel" setting should now be the default for all new connections initiated by that user.

Note: Since this is a CURRENT_USER attribute, this command must be executed for every user account that utilizes the Remote Control Viewer on that specific workstation.
