I have two monitors connected to my computer (via vga and DVI-D). I am using the plugable USB 3.0 HDMI to Connect my Projector via the HDMI port on projector. Displays Identifies all three in Extend, But I can not duplicate (1 and 3) or (2 and 3).
I need my power point duplicated on either (1 and 3) or (2 and 3).
I can only duplicate (1 and 2). The projector is on 3 (via the plugable. Please advise. Thanks
