I have two identical Samsung screens hooked up to my R9 380 (hdmi and hdmi>displayport) and a third TV display hooked up via VGA>DVI (plans to upgrade to hdmi>dvi once the cable arrives). My settings have the desktop to extended but I would like to limit my desktop extents based on the on/off state of TV display. Basically, the TV is only on when I want to watch a movie but my cursor can get lost off the edge of the second display because the GPU thinks there's more display space there. Is this possible?
R9 380 with fully updated Radeon Software installed.
