Image persistence (image sticking)
•Image persistence is when a residual or "ghost" image of a previous image remains visible on
the screen. To alleviate image persistence, turn off the monitor for as long as the previous
image had been displayed.
•Try not to operate the LCD with a "fixed" image on the screen for more than thirty minutes.
The screen has green / red / blue / white dots or defective pixels.
This is due to the characteristics of the panel itself, and is not a malfunction of the product.
The display is green or purple.
Make sure that the RGB / YPbPr setting of the input connector is correct.
