TIPS

•  Using this monitor’s screen-size switching or dual-screen display functions to compress or expand the screen for commercial 
or public viewing in establishments like cafes or hotels may infringe on the rights of the creators, as protected by Copyright 
Law, so please be careful.
•
  When “Enlarge” is set, the screen size is fixed to WIDE mode.
•
  When dual-screen display is selected, the screen size cannot be set to Dot by Dot or CUSTOM.
•
  The appearance of the original video may change if you select a screen size with a different aspect ratio than the original 
image (e.g. TV broadcast or video input from external equipment). 
•
  When an ordinary non-wide image (4:3) is viewed with the whole screen using the screen-size switching function of this 
monitor, the edge of the image may be lost or appear distorted. If you wish to respect the creator’s intentions, set the screen 
size to NORMAL.
•
  When playing commercial software, parts of the image (like subtitles) may be cropped. In this case select the optimal screen 
size using the screen-size switching function of this monitor. With some software, there may be noise or distortion at the 
edges of the screen. This is due to the characteristics of the software, and is not a malfunction.
•
  Depending on the original image size, black bands may remain at the edges of the screen.
