Has anyone else experienced a USB to HDMI adapter slowing down the changing of slides? We have a Plugable USB 3.0 to HDMI Video Graphics Adapter. The speed slow down does not seem to occur when we are only attached to our main projector via a direct HDMI connection. When the USB adapter is plugged in to connect the confidence monitor that is when the slow down shows up (but now 100% of the time).
Thanks!
