Remote Access to a Mosaic Display

Hello All,
I am helping a user with accessing their Mosaic Display remotely and we are running into some issues. Specifically, we are having issues where the the Mosaic technology is in conflict with Real VNC. I’ll include the hardware information at the bottom of the post.

There is no problem seeing all the monitors through VNC Viewer until the Mosaic is being configured. If the VNC server is running, during the configuration of the mosaic, there is a dialog box showing that there is a conflict with the following applications and lists -VNC Server-.
“VNC Server must be stopped before it will let you finish the Mosaic configuration”.

We tried stopping the VNC Server then configuring the Mosaic and then re-starting the VNC Server. After this, you can remotely connect but get black screen saying “cannot display Desktop at this time”.

Has anyone had success accessing a Mosaic display remotely through VNC or other means?

RAM: 2x Kingston DDR4-2666 8GB ECC

Thanks all for your comments.

I’m really interested in best practices for remotely administering a system with a large Mosaic display array as well.

I actually found this question on a public forum. The only response was a direction to post the question here. It’s a bit disappointing to see that after Ben asked, nobody even felt like following up.

So here’s hoping. Are there any users here who use Mosaic to configure large display arrays and remotely administer them? What tools do you use? What are the best prectices?

Thanks

Hi Flo3,

Thanks for bubbling this question back up.

I can think of a number of ways to remotely manage a display wall.

MOSAIC Utility

  • Download configuremosaic from here - Mosaic Utility Driver (nvidia.com)
  • Many customers will script the command line so it starts at run time.
  • If you have used the Control panel to setup your wall running
    * configuremosaic.exe listconfigcmd
    • will give you the command options to recreate your current wall.

NVIDIA WMI

  • NVIDIA Enterprise Management Toolkit - NVIDIA Enterprise Management Toolkit - NVWMI 2.33
  • Should be installed with the driver but the link above will allow you do a standalone install.
  • In the sample folder is a Powershell script called ManageOverlaps.ps1 which does a similar function to the configuremosaic tool. You will need to edit the script to match your layout.
  • The advantage of NVWMI is that you can run it from a remote machine.

3rd party options

TeamViewer - TeamViewer: The Remote Desktop Software

  • Most system integrators I have worked with over the years use TeamViewer.
  • Will be slow the larger the display wall.

VNC

Would be interested in what other customers have discovered over the years to help manage their display walls.

came across this additional method recently

Windows RDP Shadow mode

Shadow mode allows you to connect to an session on a remote desktop.
To setup shadow mode I recommend googling " rdp shadow windows 10". The instructions require GPO settings to allow full control of a remote desktop; remote desktop and print/file sharing enabled.

On the client the command line to launch rdp in shadow mode is:

mstsc.exe /v:servername /prompt /shadow:1 /control /noconsentprompt

servername - is the name or ip address of the machine running mosaic.
shadow:1 - is the session number for the user on the machine. It will generally be 1 but if you have multiple users you may have to double check the number.
prompt - will put up a login UI so you can enter a user login details.
