HP 14" Monitor Pavilion ...

[rirusstek2]

When I start the computer system the HP logo appears, then the Windows Professional Screen shows up perfectly with the "running" dots on the bottom until they stop and then the screen changes to dark. After this the screen stays dark......
The computer keeps booting up normally until it finishes the sicle, however the screen stays dark .

I have tried another monitor and everything works perfectly and in a NORMAL way.

Any ideas or suggestions on why is this happening to that screen?

Thanks for your help.

If you tried another monitor , one of 2 things. Most likely your old monitor is bad or the computer is using a higher resolution then the old monitor can handle and the new monitor you used can handle a higher one. Im pretty much 99 percent sure though your old monitor is bad.

Yes I tried another monitor and n problem whatsoever.

Is there a way to lower the resolution that the computer puts out?

On the old monitor all the colors and shapness are perfect when the blue HP Logo Screen and the WinPro Logo and dots appear.

Also, I noticed that the 9 pin is missing from the male at the end of the cable that attachs to the video card.

Thanks so much for the help.

If the pin is gone the monitor probally is junk, and yes you can lower your resolution, connect to the monitor that works on it, go to properties on the background and you can lower it from there. Then just connect the other monitor. By the way if the monitor doesnt work on resolution 800x600, junk it.

OK I'll try to lower the resolution to 800x600 with the other monitor and try again to see what happens.

I started looking for a description of the connector and foun this, I don't know if it applies to that monitor, but here it is.

Well I cant say right or wrong on any of that part. Ive worked with electronics but I do not know much about monitors actual parts so im not going to act like I do. So I still stand with if the monitor dont work trash it lol. For working with monitors can be deadly if you dont know what your doing due to many factors.

The default in lots of cases is 640 by 480 VGA. Any VGA monitor you plug in should display at that resolution. You have that because the splash screens are OK.
Better to set everything there, then try higher as a test before you permanently set it.

I'm quite sure that's my case, however I'm not getting inside, no .. no !!!

With that monitor (HP-D3857A) I can get to the SETUP menu with no problem and I can access SAFE MODE and up to the WinXP-PRO screen.

So, as you said, it has to be that the Computer is set to a High Resolution and the monitor can't handle it. I'll get a hold of another monitor and change the resolution and that might be it.

Thank again for the help electronicsfreak

Anyways, these are the details for the Computer

Pentium III
800GHz
Video Card = AGP NVidia RIVA TNT2 ULTRA
Windows XP Professional SP2

I had the Monitor in question saved from a while back and I was given the computer without a monitor.

I'm using a Laptop to get all this information and help from the GREAT Tek-Tips Forums

Thank you all ....

Pin 9 is a "no connect" pin. It isn't broken if it isn't there! The original VGA monitors had no pin 9.

However it means that this quite an old monitor. Try to get the specifications on the web. Resolution, horizontal and vertical frequencies.

If windows does not identify the monitor (which is probably your case), it will default to a certain resolution. This default is not necessarily compatible with your monitor.

The safe mode works at the standard 640 x 480 , 70Hz VGA resolution. So from your other monitor setup, lower the resolution down to this, and then swap the monitor.

Once you get the specs of your monitor you can select the proper resolution and sync frequencies in XP that will match your monitor.

Thank you felixc for your input, now I also larned that the PIN is not broken, the monitors date is 1995 but it is in excelent condition (physically) however Tomorrow I'll find out how it is operationally when I lower the resolution with another newer monitor.

Thank you all for you great help !!!!

What hurts with WinXP is probably the vertical refresh rate. The highest vertical refresh rate the less flicker. XP tries to make it as high as it can for a given monitor. The monitors now have a "DDC" channel from which the OS will identidy the monitor and may also read a table of refresh parameters.) Most monitors can now display at 120Hz of vertical refresh rate. Ten years ago 85 Hz was very good. So try to play with the vertical refresh rate in XP. Start at 60Hz and move up. The maximum refresh rate will also vary depending on the chosen resolution. 800 x 600 @ 75Hz, and 1024 x 768 @ 70Hz for example.
