When I connect my PC to my products 15 pin VGA Computer port, the screen is displayed, but all 4 sides are clipped. What should I do?

• The projector's 15 pin VGA “Computer” connector has two video input signal modes; Analog-RGB and RGB-Video. When using this connector with your computer, make sure that you have selected Analog-RGB as the signal mode. If RGB-Video is selected, the displayed image will be clipped on all four sides.
  
  To change the setting, follow these steps:
  1. Press the Menu button on the control panel or remote control, to bring up the projector's menu.
  2. Use the arrow buttons to navigate to the Settings menu, then press Enter.
  3. Select Computer Input and press Enter.
  4. Select Analog-RGB and press Enter.
  Your computer image will now appear without any clipping.
