I am trying to connect 3 monitors up to our radeon r7 200 series card. One main monitor and two side monitors for our chroma key (green screen) studio setup. Only have 1 VGA port, 1 DVI port and 1 HDMI port. The main monitor is hooked up via DVI and when I hook up one of the side TV monitors via HDMI the resolution stays at 1920x1080 for both monitors. Great, but I need to get the 3rd monitor involved. To do this we used an HDMI splitter but now the main display is still 1920x1080 and the other two TV monitors went all the way down to 640x480. I tried hooking up the third monitor via VGA but it doesn't recognize the third display. Not sure how to fix this issue.
