thanks for reply ...which may 'work ' however if I want to use a TV for a bigger screen and I am mirroring the Mac
screen then this is still an issue ???
Although unplugging the TV [hdmi] from the Mac does allow Resolume to resize the monitors [ since when btw did the output monitor [ on tutorials from resolume site] become the composition monitor ??!! and remain so when the TV is plugged back in ...
Well almost .... the screen monitor still has black edges ..which may have something to do with the Mac display settings which I havent tried yet !!
OK .... the Mac display settings have to be on the middle of the scaled settings for the monitors to be to be optimally functioning ... omg what a palaver ???!!!
