Here is the set up. One laptop connected to one HDMI cord into an HDMI splitter. From that splitter are two HDMI cords to two projectors. Currently the projectors show a duplicate of the computer screen but I want the projectors to show an extension so I can have an open window on my laptop but a different screen on the projectors. Been trying every setting for hours but when I try any other setting but "duplicate screen" it doesn't show up. Anyone out there think they know whats up?
