@sdetweil said in Getting MMM to open on the second monitor and correctly size:

electronOptions: { x:1920,fullscreen:false , width: 600, height:800},

the first option gives me this error

var config = {
electronOptions: { x:1920,fullscreen:false , width: 600, height:800},

WARNING! Could not validate config file. Starting with default configuration. Please correct syntax errors at or above this line: C:\Users\Dell Server\MagicMirror\config\config.js:11

The second option
