Multiview 4 HD Output Question

Hi,

I want to use the Multiview 4 HD with two SDI Signals. Is it possible to show only 2 pictures on one screen?

No, the MultiView 4 HD has a fixed quad split output layout.

You could display two inputs on a single screen using the Picture-in-Picture feature of the ATEM Mini. Or you could look at something like the Decimator DMON-QUAD which has more control over the number and layout of the windows in its multiviewer
