Lcd Panel Illumination During Bulb; Recording Card, Image Size Setting - Canon EOS-1DX Instruction Manual

When the shooting mode is set to "Bulb", the viewfinder information will not
be displayed even if [Enable] is set.

LCD panel illumination during Bulb

You can set the LCD panel illumination behavior during Bulb exposures,
such as whether it stays on during the exposure, and whether it turns off or
stays on when the <U> button is pressed.
OFF: Off
When the Bulb exposure starts, the LCD panel illumination turns off.
Pressing the <U> button during a Bulb exposure illuminates the LCD
