Part of the display of the middle main screen will be blocked by the master of ceremonies or newcomers, which will affect the effect.

When a newcomer stands in front of the main screen, the camera will affect the light absorption because the background light is always changing, thus affecting the photo taking effect.

Generally, the stage will be lighted for newcomers, and if there is light in the background, the lighting effect will be affected.

The small screens on both sides can also be used as the background of the stage, which is more natural and unobtrusive.
