EOS 7D Mark II: HDMI output mirroring

When recording HD movies over the HDMI output to an external recording device, if you are outputting the data with no information overlay (in other words a clean HDMI signal out), then you should be careful when selecting Mirroring or No Mirroring. If you have No Mirroring set, then any camera warnings (for example remaining card capacity, battery capacity or internal temperature warning) will not be shown on the external device or on the camera’s rear LCD display. If you wish to see the warnings, then make sure you select Mirroring so the warnings are shown on the camera’s LCD display.
