Missing Panels when setting up Mosaic

I am setting up a Video Wall using (2) NVS-810’s. I have used this setup in the past but now for some reason I can only see 8 out of the 12 panels when selecting my wall layout. I can see all 12 panels in windows regularly, but only 8 when I am in the Mosaic menu. Mosaic shows GPU’s 1, 2, and 3 with 4 panels each, but it will not give me the availability to select 12 when I move forward.

Hi asylvester,

what is the resolution of each panel and what is the layout of the MOSAIC Grid.

The rules for MOSAIC is that all the displays are identical in resolution/timing and the total horizontal and/or vertical display resolution is less than 16k pixels.
