When a computer monitor screen or display is shot with the camera, a bright horizontal line indicating excessive exposure is displayed in cases when the scanning rate of the monitor is faster than the shutter speed of the camera. A dark horizontal line indicating insufficient exposure is displayed in cases when the monitor's scanning rate is slower than the camera's shutter speed. The scanning frequency of a monitor varies due to various reasons during the computer operation. Adjust the scanning rate to obtain a stable image while observing the image in the viewfinder. Ⅲ Variable Scan [V.SCAN] • Basic operation Set the SHUTTER item on the OPERATION MENU screen to VARIABLE. Then move the SHUTTER knob upwards or downwards to change the shutter speed.
