user’s guide

Tilting the Display

Setting the Refresh Rate

The monitor has a tilt feature that allows you to tilt

the display back and forth as well as left and right to

find the most comfortable viewing position. To tilt

the display, grasp the sides and push the display

back or pull it toward you, or turn it left or right until

it is in the desired position. The display can be tilted

20º backward and 5º forward.

The image refresh rate is the number of times per

second that the image is refreshed; it is also known as

the vertical frequency.

Your LCD Monitor is flick-free at all supported

refresh rates.

Although your LCD monitor supports up to 75 Hz

for analog video input, we recommend that you use

60 Hz refresh rate for best performance. The table in

“Video Modes” on page 19 shows the image refresh

rates supported by the display at different screen

resolution.

To set the refresh rate with a standard Windows

installation, follow the steps mentioned in your

Windows or video card documentation.

Minimizing Power Consumption

Many PCs support industry standard power-save

signaling techniques. Power management features

reduce the display’s power consumption after a

period of keyboard or mouse inactivity.

When the monitor is in a power-saving mode, the

screen is blank and the power indicator is amber.

Pressing a key on the keyboard or moving the mouse

restores the image in several seconds. Consult your

PC documentation for information about setting the

power-saving modes.

NOTE: Do not tilt the display by grasping the

top edge.

The display accepts the signals for standard power-

saving mode, and when the PC goes into power

saving mode then the display also goes into power

saving.

Setting the Video Mode

Since the display resolution of this monitor is 1024

pixels by 768 lines, the display will perform best

when your PC is set to a screen resolution of 1024 x

768. If you use a lower resolution (such as 640 x 480),

the image is expanded to fill the screen.

Your display supports many common video modes,

as shown in “Video Modes” on page 19. Check the

documentation supplied with your PC and video

adapter card to find out which modes they support.

To see what the video mode is on your PC, check the

settings for the Display Properties in the Windows

Control Panel of your PC.

Caring for and Cleaning the

Display

To maximize screen life and prevent damage to the

LCD panel, we recommend that you:

Adjusting Your Display

This chapter contains information about how to

The HP vf52 TFT monitor uses high-precision

technology, manufactured according to HP

Display Size

304 mm x 228 mm

standards, to guarantee trouble-free performance.

Nevertheless, the monitor may have cosmetic

imperfections that appear as small bright or dark

spots. This is common to all LCD monitors used in

products supplied by all vendors and is not specific

to the HP vf52 monitors. These imperfections are

caused by one or more defective pixels or sub-pixels.

• 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.

Video Modes

Unknown Video Modes

Your LCD monitor supports the following industry-

standard combinations of screen resolution and

refresh rates. Other combinations are possible, but

may require adjustments to the image.

Like all other monitors, the your LCD monitor is

designed to work with standard video modes.

However, not all video/graphic cards use only

standard display modes.

For optimum performance, set your PC to a screen

resolution of 1024 x 768 at a 60 Hz refresh rate.

Your LCD monitor uses state-of-the-art technology,

which is designed to automatically synchronize to

any display video mode listed in the above table. We

recommend that you choose one of the supported

video modes listed above. If you choose an unknown

video mode, you will need to manually adjust the

clock, phase, and image position; the resulting

display may still be bad.

If you must use an unknown mode that is not in the

listed display video modes, you should run Auto

Setup first. If Auto Setup doesn’t provide adequate

image adjustment, then you must manually adjust

the clock, phase, horizontal position, and vertical

position. If this does not work, please chose a
