A recent support case showed a strange behaviour of a dual Nvidia card setup with 8x 1920x1200@50hz output. 

The symptom was that there were random pixels flickering on the outputs when Vertex (DirectX11) was rendering in Fullscreen.

The total resolution was 15360x1200. By reducing the fullscreen window size by one pixel in width the flickering went away. 

This seems to be an issue with Windows 10 and the nvidia driver. To change this setting the 'Render Window Size' can be adjusted in the system inspector of Vertex.
