							Entering User Modes
The video controller signal may occasionally call for a mode that is not preset if:
●You are not using a standard graphics adapter.
●You are not using a preset mode.
It this occurs, you may 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 modes and saved in memory. The monitor 
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In 
addition to the factory preset modes, there are at least 10 user modes that can be entered and 
stored.

							Using the Auto-Adjustment Function (Analog Input)
When first setting up the monitor, when conducting a Factory Reset of the computer, or whenever you 
change the resolution of the monitor, the Auto-Adjustment feature will automatically engage, and 
attempt to optimize your screen for you.
You may also optimize the screen performance for the VGA (analog) input at any time by using the 
Auto button on the monitor (see your model's user guide for the specific button name) and the auto-
adjustment pattern software utility on the disc provided (select models only).
Do not use this procedure if the monitor is using an input other than VGA. If the monitor is using a 
VGA (analog) input, this procedure can correct the following image quality conditions:
●Fuzzy or unclear focus
●Ghosting, streaking or shadowing effects
●Faint vertical bars
●Thin, horizontal scrolling lines
●An off-center picture
To use the auto-adjustment feature:
1.Allow the monitor to warm up for 20 minutes before adjusting.
2.Press the Auto button on the monitor front panel.
●You can also press the Menu button, then select Image Control > Auto-Adjustment from the 
OSD Main Menu.
●If the result is not satisfactory, continue with the procedure.
3.Insert the disc in the disc drive. The disc menu is displayed.
4.Select Open Auto-Adjustment Software. The setup test pattern is displayed.
5.Press the Auto button on the monitor front panel to produce a stable, centered image.
6.Press the ESC key or any other key on the keyboard to exit the test pattern.
NOTE:The auto-adjustment test pattern utility can be downloaded from http://www.hp.com/support.Using the Auto-Adjustment Function (Analog Input)29   
						

							Optimizing Image Performance (Analog Input)
Two controls in the on-screen display can be adjusted to improve image performance: Clock and 
Phase (available in the main menu).
NOTE:The Clock and Phase controls are adjustable only when using an analog (VGA) input. These 
controls are not adjustable for digital inputs.
The Clock must first be set correctly since the Phase settings are dependent on the main Clock 
setting. Use these controls only when the auto-adjustment function does not provide a satisfactory 
image.
●Clock—Increases/decreases the value to minimize any vertical bars or stripes visible on the 
screen background.
●Phase—Increases/decreases the value to minimize video flickering or blurring.
NOTE:When using the controls, you will obtain the best results by using the auto-adjustment 
pattern software utility provided on the disc.
When adjusting the Clock and Phase values, if the monitor images become distorted, continue 
adjusting the values until the distortion disappears. To restore the factory settings, select 
Yes from 
the 
Factory Reset menu in the on-screen display.
To eliminate vertical bars (Clock):
1.Press the Menu button on the monitor's front panel to open the OSD Menu, and then select 
Image Control > Clock.
2.Press the + (Plus) or – (Minus) buttons on the monitor's front panel to eliminate vertical bars. 
Press the buttons slowly so that you do not miss the optimum adjustment point.
3.After adjusting the Clock, if blurring, flickering, or bars appear on the screen, proceed to adjust 
the Phase.
To remove flickering or blurring (Phase):
1.Press the Menu button on the monitor's front panel to open the OSD Menu, and then select 
Image Control > Phase.
2.Press the + (Plus) or – (Minus) buttons on the monitor's front panel to eliminate flickering or 
blurring. Flicking or blurring may not be eliminated depending on your computer or graphics 
controller card installed.
To correct screen position (Horizontal Position or Vertical Position):
30Appendix B   Support and troubleshooting   
						

							1.Press the Menu button on the monitor's front panel to open the OSD Menu, and then select 
Image Control > Horizontal Position and/or Vertical Position.
2.Press the + (Plus) or – (Minus) buttons on the monitor's front panel to properly adjust the 
position of the image in the display area of the monitor. The Horizontal Position shifts the image  left or right; the Vertical Position shifts the image up and down.
Button lockouts
Holding down the power button or Menu button for ten seconds will lock out the functionality of the buttons. You can restore the functionality by holding the buttons down again for ten seconds. This 
functionality is only available when the display is powered on, displaying an active signal, and the 
OSD is not active.
