Entering User Modes
The video controller signal might occasionally call for a mode that is not preset if:
●
You are not using a standard graphics adapter.
●
You are not using a factory preset mode.
It this occurs, you might need to readjust the parameters of the monitor screen by using the on-screen
display. Your changes can be made to any or all of these factory preset modes and saved in memory.
The monitor automatically stores the new setting, then recognizes the new mode just like it does a
factory preset mode. Also there are at least ten user modes that can be entered and stored.

LCD Monitor Quality and Pixel Policy
Your LCD monitor uses high-precision technology, manufactured according to high standards, to help
guarantee trouble-free performance. Nevertheless, the display might have cosmetic imperfections that
appear as small bright or dark spots. This is common to all LCD monitor displays used in products
supplied by all vendors and is not specific to your LCD monitor. These imperfections are caused by one
or more defective pixels or subpixels.
A pixel consists of one red, one green, and one blue subpixel. A defective whole pixel is always turned
on (a bright spot on a dark background), or it is always off (a dark spot on a bright background). The
first is the more visible of the two. A defective subpixel (dot defect) is less visible than a defective whole
pixel, and is small and only visible on a specific background.
To locate defective pixels, the monitor should be viewed under normal operating conditions and in
normal operating mode at a supported resolution and refresh rate, from a distance of approximately
50 cm (16 in). We expect that, over time, the industry will continue to improve its ability to produce
displays with fewer cosmetic imperfections, and we will adjust guidelines as improvements are made.
