HP Business Monitors - Optimizing the Display on Flat Panel Monitors

HP flat panel monitors contain a digital Liquid Crystal Display (LCD) and typically contain an analog to digital conversion (ADC) module to support the legacy analog video cards. ADC modules have improved in recent years to accommodate the auto-adjust function on the most monitors. However, the ADC modules are limited by the following:

  • Graphics card

  • Operating system

  • Video driver revision

  • Graphics mode including resolution and refresh rate

NOTE: HP monitors using digital connections (DisplayPort, HDMI, or DVI connections) are not subject to the same limitations as analog connections (VGA, S-video, composite, and component connections). For more information about digital and analog connections, see TV Cable and Connection Types .

Improper resolution settings and analog adjustments can result in the following display problems:

  • Fuzzy or blurred images

  • Out-of-focus images

  • Unstable images

  • Unwanted lines or noise on the screen

Perform the follow to obtain the best possible analog output:

  1. Download and install the latest graphics card driver from the HP Support Web site .

  2. Set the desktop resolution to match the monitor native resolution. For more information, see HP Flat Panel Monitors - Changing the Screen Resolution .

  3. Set the refresh rate to 60 Hz.

  4. Download and install a monitor utility, such as the HP Display Assistant Utility , from the HP Support Web site . This utility provides a simple walkthrough procedure for setting up an analog display.

  5. Adjust the monitor's analog clock and phase to match the graphics mode with the auto-adjust function. For finer adjustments, use Image Control under the OSD Menu. Refer to the monitor User Guide for more information.
