Monitor hood having light-shielding door

A monitor hood having a light-shielding door and mounting on a monitor having a top plane, a left plane, and a right plane, the monitor hood comprising:

• a left plate mounted on the left plane;
• a right plate mounted on the right plane;
• and
• a top plate mounted on the top plane, the left plate and the right plate connecting to both sides of the top plate respectively, the top plate being composed with an upper component and a lower component and having an opening on the upper component and the lower component for allowing a color calibration device to pass through, the top plate comprising a track along a first direction and comprising:
• a door having an indentation at a front end and having a groove at one side along the first direction for coupling with the track and allowing the door for moving along the first direction at the opening and for selectively moving to an opened position or a closed position, the door being configured between the upper component and the lower component, the color calibration device being allowed to pass through the opening when the door moves to the opened position, and the indentation matching closely to the edge of the opening facing the front end for shielding lights when the door moves to the closed position.
