I have three montiors. Two are at different heights relative to the main screen. In Windows display properties you can drag the monitors up and down to move them about, but there is a 'snap' action- so I can't precisely adjust the position of the screen,
e.g the default position is 1680, 150, as soon as I drag it down it jumps to 1680, 255. I need a value between 150 and 255!
