Adjusting screen quality

The auto adjustment feature automatically fine-tunes the image quality for display size, position, clock, and clock phase each time a new video mode is displayed. For more precise adjustments of VGA input, download and run the HP Auto Adjustment software from the HP website.

If you want additional image quality improvement, use the Clock and Clock Phase controls of the monitor to fine tune the image. Use these controls only when the auto-adjustment function does not provide a satisfactory image.

note:

The Clock controls are adjustable only when using an analog input. These controls are not adjustable for digital inputs.

The Clock must first be set correctly since the Clock Phase settings are dependent on the main Clock setting.

Clock - Increase or decrease the value to minimize any vertical bars or stripes visible on the screen.
Clock phase - Increase or decrease the value to minimize video distortion or video jitter.

Use these controls only when the auto adjustment function does not provide a satisfactory monitor image in analog mode. To obtain the best results, download and use the auto-adjustment pattern software utility from the HP website:

Allow the monitor to warm up for 20 minutes before adjusting.
Display the adjustment-pattern application provided on the CD.
Access the OSD menu, and then select Image Control.
Set the main Clock settings correctly first, because the Clock phase settings depend on the main Clock settings.

If the monitor images become distorted, when adjusting the Clock and Clock phase values, continue adjusting the values until the distortion disappears.

To restore the factory settings, access the OSD menu, select Restore factory settings, and then press OK.

Tips and recommendations

Unplug your monitor from the wall outlet before cleaning. Clean the monitor plastics with a clean cloth dampened with water. Do not use liquid cleaners or aerosol cleaners. Clean the monitor screen with an antistatic screen cleaner.
Do not open your monitor cabinet or try to service this product yourself. Adjust only those controls that are covered in the operating instructions. If your monitor is not operating correctly, or has been dropped or damaged, contact your HP authorized dealer, reseller, or service provider.
Use only a power source and connection appropriate for this monitor, as indicated on the label or back plate of the monitor.
Never disconnect the monitor by pulling the cord.
Turn your monitor off when not in use. You can substantially increase the life expectancy of your monitor by using a screen saver program and turning off the monitor when not in use.
When removing the monitor base, place the monitor face down on a soft flat area to prevent it from getting scratched, defaced, or broken.
Burn-in image damage might occur on monitors that display the same static image on the screen for a prolonged time. To avoid burn-in image damage on your monitor, always start a screen saver or turn off the monitor when it is not in use for a prolonged period.
