Michael,

Take a look at the function key combinations which toggle the display from the laptop alone, to the display with the monitor and the laptop, and the external monitor alone.

In those combinations, you should find one particular set which gives the key combinations for laptop alone, laptop and external together, and laptop off with external on. It sounds as if you have toggled the last of those three combinations. I do not use an HP laptop, so I cannot tell you which keys are the display control keys on an HP.

On my laptop, they are F5, F6, and F7. My suggestion is to look at your F Keys, to find which ones control the external output, and go from there until you discover the combinations which will contribute to displaying back to your laptop's screen alone.

Good Luck,
-a.

SOURCE: HP pavillion dv9005 no display - works fine on external monitor

If the notebook's video card (which may be on the motherboard) is successfully displaying images on an external monitor it sounds more like a problem with the notebook display or its connections. Probably the motherboard is OK.

When I turn on my HP Pavilion 1x1000 It stays on ,but there is no image on the screen, and stays on please help.


A) Post THE Product Number on the bottom of the laptop. It's in the white Service Tag. P/N = Product Number.

B) On the left/bottom side of the LCD screen frame (Display Bezel), there is a switch. Looks like a small button.

This is the Internal Display Switch. (May not be in this exact position for your model. Look around on the Display Bezel, that surrounds the LCD screen)

When the laptop is closed, the switch turns off the display, (Image on screen), with the computer still on.
Tap it a couple of times lightly, with the eraser on the end of a number 2 pencil.

See if anything happens. That switch may be bad.

C) Laptop off, monitor off, connect a VGA monitor to the VGA port on the laptop.

Example of a VGA cable, and VGA connector, (Port),

http://en.wikipedia.org/wiki/VGA_connector

You can use a CRT monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

C) Turn the monitor on. If a CRT type of monitor allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external VGA monitor.

IF not;
There are at least 3 display options,

1) Internal monitor of laptop ONLY
2) Internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key. At the same time tap once on the Display Toggle-Over key.

Don't know what exact HP laptop you have. For most HP's it is the F2 key, or the F4 key, that is the Display Toggle-Over key.
(Key has an empty rectangle on it, with a vertical line on each side)

Still no display on the external VGA monitor?
Hold the Fn key down again. (Bottom left of Keyboard)
Tap once more on the Display Toggle-Over key

NO display on the external VGA monitor, means you have a bad graphics chipset.

(By using an external VGA monitor, you are bypassing the Internal Display Switch, and the Display Assembly. (Internal monitor of laptop)

If you have a display on the external VGA monitor, you have a problem with;

1) Video Cable, (Display Panel Cable for HP)
or
2) Display Assembly

Post back with your results, and if you have a display on the external VGA monitor, we will go on.

If you do not have a display on the external VGA monitor, you are looking at motherboard replacement.

Post back in a Comment.

My hp compaq model 510 is not working with projector.projector is not working on this laptop plz provide a proper solution.


You are not providing enough information to help you.
Have you set the display to use an external monitor or dual monitor? That is how laptops work with projectors. You normally can set the system for dual display and either mirror the displays or use the second display (projector) for power point or other presentation.

If this does not fix the problem, post more information on why it is not working for you.

Using notebook display and external monitor: HP Pavilion zd8205us primary display is garbled, secondary display is clear and good, It doesn't matter which display device you set as primary or secondary


try to switch the blue VGA cable that is connected from the laptop to the external monitor. You may also restart your laptop and set aside the external monitor to check if the laptop is still experiencing garbled display... If it still is, then it is a monitor issue and need to address to HP personnel by calling HP hotline. Otherwise your issue will be resolved by simply doing that..

This could be due to presence of static charges on the notebook or hardware malfunction of the video card or defective LCD display screen of the notebook. To resolve the issue, perform the following steps.
Step 1: Hard Reset
To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.
This will discharge the static charges from the notebook. Now check if the display works fine or not. Incase, if the issue persists, then the video card or LCD screen must have gone bad, and to isolate the same, please connect an external monitor to the notebook and check for the display on it. You can follow the steps below to connect an external monitor to the notebook.
1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

If your notebook is under HP warranty, then contact HP to get the notebook repaired for free of cost.
