The shutter speed should be set to variable scan mode. The variable scan mode is used to match the GY- DV300’s shutter speed with the variable scan frequency of computer screens, etc. When shooting a computer screen with the camera, bright over-exposed horizontal stripes will appear in the picture if the screen’s scan frequency is faster than the camera’s frequency, and dark under-exposed stripes will appear if the screen’s scan frequency is slower than the camera’s scan frequency.

While observing the LCD screen, adjust the shutter speed until a stable image is obtained.
