Hi all
Im building PC for video wall using 3x2 monitor
For 6 monitor i use 2 RTX A4000
I’ve configure mosaic for 6 monitor successfully, but i want 1 more monitor configured as non mosaic.
I’ve plugged 7 monitor in 2 RTX A4000, in non mosaic mode, all the monitors are active, but when i activated mosaic mode for 6 monitors, the 7th monitor was deactivated by system. What should i do.
I found setting named MOSAIC +1 but i can not implement it on my PC,
Thanks in advanced for your help.
Hello,
I have the same problem.
We made a configuration with 6 monitors in 3x2 using 2 T1000 cards.
We have another one to make a Mosaic +1 and control the videowall from it.
All seven monitors work when connected to the workstation and we can configure the 6 monitors in mosaic mode, but if I try to activate the option MOSAIC +1 from de CMD line it gives an error and the configuration is not applied.
The 7th monitor doesn’t appear in the Nvidia configuration panel when MOSAIC is applied.
My questions are:
It is possible to configure a MOSAIC + 1 with our cards (QUADRO T1000)?
If not, What cards do we need?
Is it necessary a Quadro Sync card to make this configuration?
In case it helps, I have attached the error file.
Regards

Hi MadbyTech,
Thanks for the question. MOSAIC+1 should work with Quadro T1000. Generally speaking we QA with the larger GPUs being used to set MOSAIC and the +1 being on a smaller GPU. Your setup is the opposite so my be causing issues.
Quadro Sync II is not needed (not supported on T1000). The message in the error test is just for information only.
<info infoString="No QuadroSync Devices found on this system" />
Can you share the commandline text you are using to set the display and confirm which displays are connected to which GPUs.
thanks
Hi DougT.
Thanks for your answer.
The command I use taking in account that we want the “+1” monitor will be the main screen, is the following:
Configuremosaic.exe set rows=1 cols=1 res=1920,1080,60 out=1,3 nextgrid rows=2 cols=3 res=5760,2160,60 out=0,0 out=0,1 out=0,2 out=1,0 out=1,1 out=1,2
The monitors are 6 x Samsung 55" VM55B-U with a resolution of1920x1080 ppp each, connected via DP.
For the "+1 " monitor we have tried differents models with differents resolutions, but the one with the resolution of the command is an HP P24 G4 connected via DP.
The first row (the upper part of the videowall) is connected to the first card.
The botton row of the Samsung monitors and the HP monitor is connected to the second card.
We have done tests changing the card to which the HP monitor is connected and changing the command, but the results have been the same.
I would appreciate it if you could help us on this issue.
If you need more information, please, tell me.
Regards
For +1 display you will need to add a 3rd GPU to the system which will host the +1 display,
Unfortunately, although you are using only 6 of the 8 displays, with multi-GPU in MOSAIC mode the unused display outputs join the MOSAIC GRID and cannot be re-used for the +1 display.
So with a 3rd GPU the command line would look like:
configuremosaic.exe set rows=1 cols=1 res=1920,1080,60 out=2,0 nextgrid rows=2 cols=3 res=1920,1080,60 out=0,0 out=0,1 out=0,2 out=1,0 out=1,1 out=1,2
Also the res is the per display resolution and not the total resolution of the MOSAIC GRID.
Hello DougT,
What you say clarifies many things and confirms what we already suspected.
Apart from changing the command parameters, we need a third graphic card.
A few days ago we tried it with a non-Quadro graphics card, and it didn’t work. I understand that it has to be another graphic card of the same type or at least that uses the same drivers to work correctly.
I appreciate the support offered and when we carry out more tests I will comment again.
Thank you very much for the help.
