Brendan, does the Red LCD have the heads-up display visible? You should be seeing the roll and clip numbers, frame guide overlays, and a histogram at the bottom with various indicator lights. That is all enabled by default. If you are seeing all that but not seeing the little red dot or Roll/Clip# turn red when recording, then that is very odd. If you're not seeing any of that, but only seeing the video feed on the Red LCD, then the default overlays have been turned off in the menu and you need to turn them back on.
Usually, tapping once on the Touch LCD will bring up the menus if 'Auto Hide Menus' has been enabled. If there is a lock symbol in the top corner of the screen, then you need to hold your finger on the lock symbol for a few seconds to unlock the screen.
Next go to Menu > Settings > Display > Monitor Control. Select the 'Monitor' tab and select Brain LCD from the drop down scroll menu on the left. Go to the 'Overlay' tab and select 'Standard.' Back out of the menus and your LCD should now have all the info back on. Here's the relevant page from the Manual:
