They are exploring the way to lower the brightness of the touchscreen control panel. If brightness setting is not available, is it possible to enable screen saver on both touchscreen control panel and the main video screen after certain inactivity period? 

Use case:

Currently these devices don't have any setting to control brightness of the MIMO touch screens. If one would be in a dark room this would affect a meeting or presentation because of the brightness.

Motivation:

Since this is a touchscreen device, it would be great to have the setting to calibrate the brightness of them as you would do with almost any other screen.

Existing workarounds:
None
