Important Monitor Features

LG L3020A - Important Monitor Features - 1

Swapping Function

You can swap the main screen and the sub-screen when the PIP/POP/PBP function is used.

LG L3020A - Swapping Function - 1

Spectacle Function

The screen center area is close to a 4:3 ratio and the outskirt area is expanded by more than 16:9. Therefore, the different screen ratio is applied for each area. Because most ordinary people concentrate their focus on the screen center, a non-linear ratio increase at the outskirt area is not recognized, which makes it possible to watch 4:3 screen with a wide screen.

However, the spectacle function is useful in watching motion pictures but is not suitable for the PC environment in which you perform graphic or document work.

LG L3020A - Spectacle Function - 1

Sleep Function

When watching AV/DVD/HDTV – The monitor will be automatically turned off after a certain period of time.

The vertical frequency or refresh rate is the times of image display per second. The unit is Hz. \* Horizontal frequency: The horizontal interval is the time to display one vertical line. When 1 is divided by the horizontal interval, the number of horizontal lines displayed every second can be tabulated as the horizontal frequency. The unit is kHz.

The screen image looks abnormal.

● Is the screen position wrong? Do thin lines appear on the background screen? ● Horizontal noise appears or the characters look blurred. - Unable to adjust the horizontal/vertical position in the Zoom menu. - Screen size is automatically adjusted when connected to the PC. ● Brightness differs in the main and sub screen when connected to the PC. - D-Sub analog signal – Press the "AUTO" button in the remote controller to automatically select the optimal screen status that fits into the current mode.
