Jeff,
I believe the HDMI port isn't activated yet. I've tried connecting my desktop monitor but to no avail.
I've been looking at cheap ebay HDMI viewfinders to solve the brightness probem. So far I've been using a jacket draped over my head and the camera to do adjustments. I suspect a proper shade will help but a viewfinder would be ideal.
Love your Youtube channel, by the way :-)
