# Main screen view
The main display may be temporarily turned off due to some reason. In this case the OS will move the TrueConf Room main window to the second display. If you want TrueConf Room to switch to the first display automatically as soon as this display is turned on, you need to check the Pin Main Screen on the current display box.
With TrueConf Room Pro, you can adapt the main screen view to your preferences and corporate branding.
The main screen parameters are configured in the Main screen section of the settings menu.
Here you can set your own background for the video area. To this end, select the Custom in the Video area background and click the Upload an image button.
When setting a custom background, please pay attention to the pixel size of your image. It should match the resolution of the display that shows the application’s main screen.
You can enable or disable:
- Logo
Select the Custom option and click the Upload an image button to use your logo. The supported image type is svg.

# Sleep mode
TrueConf Room supports sleep mode in which the microphone and camera connected to the endpoint are turned off, and the "away" status 
is set for the account authorized in the endpoint.
The background image with a clock and QR code with a link to the control panel will be displayed instead of the main screen if TrueConf Room is launched with TrueConf Room Service:
# Activation
Sleep mode can be activated in three ways:
Automatically when TrueConf Room is inactive; the timeout is set in TrueConf Room Service settings
When the operating system, where the endpoint is installed, enters sleep mode
Manually from the control panel by clicking the button
.
Sleep mode will be activated on all displays except for the monitors that were specified at startup with the --ignore_monitor parameter (check the section "Using command line parameters").
# Exiting sleep mode
The TrueConf Room endpoint exits sleep mode in the following cases:
When you start using the mouse (movement, click) or keyboard connected to the PC where the endpoint is installed
When an incoming call is received
If a call is made from the endpoint, including the cases when it is initiated via API
When the OS, where the endpoint is installed, exits sleep mode
When one clicks on the control panel web page with a mouse.
