Why is a black screen displayed when I use the front camera after installing the TE Desktop on the Surface 3?

The reason is that no extended rear card is installed on the S5700. An S5700-EI or S5700-SI can provide only two optical interfaces for a front card. If a 4-port front card is installed, an ETPB extended rear card must be installed to provide the other two ports. Otherwise, only two optical interfaces are displayed.

The procedure for configuring dual-screen displays for virtual desktops is as follows: Prerequisites: Two monitors, a dual-screen cable, and a monitor cable 1. Use the dual-screen cable to connect the TC to the monitors. 2. On the TC login page, choose Start > Control Center > Display. 3. On the Settings tab page, deselect Optimum settings, set Display Mode to Extend, and select VGA for Primary Monitor. 4. On the DVI and VGA tabs, adjust Resolution and Refresh Rate so that their values are the same. For example, a 22-inch monitor is generally set to 1680 x 1050). 5. Contact the administrator to enable the dual-screen display policy for your VM in the management system.

Another user has logged in to this ECS using VNC.

Only one user can log in to an ECS using VNC at a time. If multiple users attempt to log in to an ECS at the same time, only the first user can log in to it successfully. For other users, the system displays a message indicating that the user is authenticated, but the screen turns blank. If this occurs, wait until the other user logs out of the ECS.

The TE Desktop can display presentation independently. Click the collapse button in the up-to-down or right-to-left layout to hide the remote and local video. Then, only the presentation pane is displayed. The video and presentation cannot be displayed on different screens.

Enable the web monitoring function on a TE series endpoint as follows: Use a remote control to choose Advanced > Settings > Security > WEB Login and select Monitor video.
