@TimGV it depends on the configuration options for the two HDMI outputs… if they are always one big screen (xwindows DISPLAY=:0) then you will have to se the size/location of each MM config to position the output on each display, instead of across the single view space if they can be configured as individual (DISPLAY=:0 AND DISPLAY=:1) then you just need to adjust the startup script (installers/mm.sh) to select the DISPLAY value

I figured out how to change the position of my center_middle. I went to the main.css file and changed the following lines. The -50% I changed to -62%. This number was selected by trial and error. Now my middle section is spaced exactly the same on the top and bottom. .region.middle.center { width: 100%; text-align: center; -moz-transform: translateY(-62%); -o-transform: translateY(-62%); -webkit-transform: translateY(-62%); -ms-transform: translateY(-62%); transform: translateY(-62%); } .region.middle.center { top: 62%; }
