I need to know the monitor resolution & refresh rate on my HP Pavilion Pentium lll 8756C computer.

The resolution your laptop is running in, or it's refresh rate is too high.
Lower the resolution, or drop the refresh rate.
It's native mode is 1440x900 at 60Hz

Are you sure the video adapter card is OK? A low-end video card may not
have the bandwith necessary to support high refresh rates at high
resolution. Just because the card will *generate* a given mode doesn't mean
that it will work well. Try the following steps.

1. Reduce the refresh rate to 60 Hz The monitor may seem to flicker a
little, but don't worry about it.

2. If there was no change, the problem is likely in the monitor

3. If that improved the resolution, then try removing any monitor extender
cables and play with higher refresh rates again. If that fixes the probem,
great, otherwise

3. Replace the videa adapter card with a better one.

The refresh rate of the hp pavilion needs to be adjusted to match that of the other PC then it will work.
I have witten a tip on adjsuting refresh rates if you need help: http://www.fixya.com/support/r9352855-adjust_or_change_monitors_refresh_rate

Your monitor does not support the display settings you have set in your operating system.
To change these settings go: (Windows 7)

Control Panel > Display > Screen resolution [Change to 1440x900]
then on the same screen, go to Advanced Settings > Monitor > Screen Refresh Rate [Set to 60 Hertz].

(This usually happened if you switched monitors, or used a TV, or maybe a projector).

You can use the same method to set up any resolution or refresh rate you want.

Did you change your monitor / resolution / card drivers / refresh rate?
Sounds like your computer resolution is out of range for the monitor. (or refresh rate)

Solution: Boot in safe mode and change the resolution, then boot to normal.

Optional: Update graphic card drivers.

Hi there,

Your monitor can easily support Windows XP resolutions. The problem almost certainly lies in your video settings. You need to lower your screen resolution and/or refresh rate.
If you can not start Windows due to this problem, you will have to start Windows in VGA compatibility mode. Follow these steps:

1. When your PC starts up, press F8 a few times
2. This will bring up a menu whereby you can select VGA mode from the list
3. Once you are logged into Windows, right click anywhere on the desktop & select "properties"
4. Then go to display settings & select a resolution of 1024 X 768.
   
5. Go to advanced settings and make sure your refresh rate is no more than 70 to 75Mhz
6. Restart Windows normally & your display should be correct.

Let me know if you have any further questions.

Best wishes,

You may need to change the resolution on the screen, in windows, you may find the "Display Options" under "Control Panel", usually this problems is caused by the computer having a hight resolution than the supported by the monitor, for your specific monitor the available resolutions are:
Support of video modes up to 1280 x 1024 at a 75 Hz refresh rate from the manual at:
http://h10032.www1.hp.com/ctg/Manual/c00264775.pdf
That means you have to chose a resolution lower than 1280 x 1024 and a frequency lower than 75 Hz. Anything higher than that on the resolution or frequency will cause the monitor to display a "Out of Sync" message and turn off shortly thereafter.
Thanks !!!

Try reducing the refresh rate of the monitor to 60Hz as you would get 1440X900 only at that refresh rate.

Refer http://h10032.www1.hp.com/ctg/Manual/c00834092.pdf

hi

reduce the resolution to a bit lower and the refresh rate to a nominal 60hz and things should get back to normal

my hunch is u r using a slightly high resolution and refresh rates

but before that try the buttons on the monitor to see if expanding the image sideways or top and bottom would help initially

cheers
pls rate if this was any help

Your resolution or refresh rate has somehow gotten altered in the display settings. Reboot the computer in safe mode and correct the display settings to fix.
