Desktop monitor p7-1254 losses at startup

My HP p7-1254 office continues to lose monitor HP 2011 x at startup. After using the Setup screen, it works very well for a short period and then start with a black screen. Go to safe mode and check Device Manager, monitor is missing device. Also when checking the menu option devices and printers, monitor is missing and icons for usb device.

Service HP replaced the motherboard last year when I got it. I've replaced the operating system to Windows 7 pro and still the problem keeps coming back.

Any help on this would be appreciated.

Problem solved!

Solution found after over a year of on and off frustrations. Here's the fix in a short description;

1. Select Control Panel

2. Select adjust the resolution

3. in the Menu of fields for multiple monitors, select "VIEW ON 1 ONLY.

Thanks for being there to help him. Solution found by chance. Twenty-eight on off cycles and no sign of back problem.

  • What is the best way to connect the Xoom to a desktop monitor?

    I would like to power mirror my screen xoom on a desktop monitor for presentations by small group to the site.  I've seen some of the threads on hdmi to vga, hdmi/DVI and hdmi to hdmi, but I'm a little confused as to what is easier.  It seems that if you go with hdmi to vga you will need some type of converter, not just a cable?  If it was just a cable that would be perfect.  In addition, another option would be to hdmi for display port (published in December 2010), has anyone tried this? Thank you!

    @uberpixels,

    I think the easiest way is using a HDMI output on the Xoom to an HDMI-> DVI Cable. or HDMI-> VGA Cable. I use an adapter at right angles (adjusted to avoid breaking), HDMI port which offers a complete female HDMI.

    Here's the thread on this adapter:

    https://supportforums.Motorola.com/message/401234#401234

    Then, connect a HDMI-> DVI Cable for the monitor. If you want to copy to VGA, you may need to add the + 5V using the applicator of tension mentioned in this thread:

  • Properties dialog boxes appear in extended desktop monitor after turning off

    I used the Office expanded shortly to develop a data model. However, when returning on the single screen of laptop, maker of data continues to display dialog boxes in extended desktop monitor and therefore invisible.

    If anyone has experienced this problem and is it possible to disable this option.


    Thank you
    Etienne Piron

    Hi Eric,.

    For some of the dialog boxes, he remembers where the dialog box is displayed, and next time the dialog box is used, it tries to display the dialog box at the same place.
    This can result in the dialog box being invisible if it was previously displayed on a subsidiary monitor that is no longer connected.

    In this case, you can move the new dialogue box on the main screen as follows:

    1 attempt to open the dialog box.

    2. tap Alt space (this opens the dropdown of the invisible dialog box).

    3 M type (this selects the Move option in the drop-down below).

    4 use the left or right arrow key to move the dialog box. (Once you've started it, you will find that you can use the mouse to position the dialog on the screen.)

    You need only this time for the dialog box. Next time it is used, it must appear in the new location.

  • What cable adapter I need to conet my elite 21.5 HP on my desktop monitor

    I bought HP elite to upgrade my monitor, but I didn't need a conection RFP, so I bought an addapter

    but also do not work. It's a way I can connect the monitor.

    Here are the specifications of your desktop HP Pavilion p7-1414 and here are the specs of your LCD display backlit LED 21.5 inch HP Elite L2201x. According to these data, the monitor only has a DisplayPort input and your computer only has a VGA and DVI output. You can't drive a monitor of DP with something other than a DP graphics card. There is no adapter that will solve your problem. You will need to purchase and install a graphics capable of DP to use this monitor. Please visit the website DisplayPort.org and this FAQ for more information on your topic;

    Q: I just bought a monitor that only has a DisplayPort connection. How can I connect to my computer that has VGA, DVI or HDMI?
    A: there is not a cost-effective way to do it. The available adapters operate only from a computer of DP to VGA, DVI or HDMI monitor and not vice versa. If you have a desktop computer, you can buy a graphics card with DisplayPort. Our best advice: before you buy a DP only monitor make sure you DP on your computer.

  • Desktop/Monitor audio best installation tips please :@)

    Hi Im new in the world of desktop computers, like Ive never had laptops before so Im used to everything being built together and would like to know any advice on the best set up with the following please.

    I just bought the 3847 Desktop Inspiron with windows 8.1 and monitor Dell S2340L.

    I am connected to the monitor using HDMI.

    I have a pair of old Genius speakers that connect using a connector headphone jack and I can put it is in the monitor or the front of the base unit.

    I don't see a connection headphone jack at the back of the device, which is where I would have preferred it to be. There is no headphone connection where the HDMI graphics card, but above of what there is pink, green and blue circular connectors. Pink has a micro top symbol but Ive means no symbol of the idea that the other two, they are circles with an arrow that goes left and another will (Im assuming that its for connectors on the left and individual right?).

    There he has a way to connect the speakers to the back of the unit rather than the front, can I 'wrong' pc by accepting the speakers via the microphone jack?

    The question because I use the software, Camstudio and Bandicam record stream videos with sound and now I can't get the sound recorded so its in headset before on taking office, he does not record when it is connected to the monitor that would be my first choice and as I say I do not see a connection headphone jack at the back.

    IM wondering if there is a way to do this via the screen or connections that are in the back of the desktop, I do not like these components to the front coming out of my cat to sniff here or pass me and break:(lol.)

    If someone things another type of speakers would resolve the issue too much, I'd appreciate this view.

    It was not any mode of employment with the bureau, if Im wondering if there is a place online that told me all about these things?

    Thanks for reading, hope, that I have not sounded too complicated or anything like that and thanks in advance.

    Ronin :)

    Here are the manuals 3847 Inspiron Desktop. Save this link for future use. Open the Inspiron 3847 PDF specification. The green back panel is your main audio "Line-out" output jack. This is where you would plug in speakers.

  • HP PAVILION 550-126: start PC Desktop Monitor question

    Installed a HP Pavillion PC with Windows 10 550-126.  I plugged my old model monitor (2009) PC Pavillion, which is a HP 2009 m.  HP 2009 m monitor had a DVI connection, so I bought a DVI adapter to HDMI to connect the new 550-126 Pavilion.  At the start of the monitor shows nothing.  It takes a long time (5-10 minutes) before the login page appears.  When starting I have pressed the "Source" button on the HP 2009 m monitor and it comes up with a block that says "Check Vidoe cable", the block is delivered on one that says DVI is scanning, then digital asset.  I'm trying to understand if the problem is I use an adapter DVI to HDMI or if there is something else that happens - or I need to get a screen that has a direct HDMI to HDMI connection.

    Thanks for the help.

    It's the adapter.

    If you want the video to appear quickly, you'll need a display more modern.

    Yours is a type of old-school LCD vice a LED modern type.

    Fortunately, most modern screens usually have a HDMI input.

  • I think that my desktop monitor is broken, how can I check for sure?

    My orange light monitor blinks after a power outage, every once in a while the led green lights but just for a second, disconnected ang plugged all back, computer tower is on but nothing comes on the screen.  I have a laptop but don't know enough about computers to hang the Tower until she.   Any suggestions how I might be able to check in with a laptop?  I need specific instructions I don't know true how all this works.  I use the color code system to connect the monitor to the tower.  The laptop has no large port to connect the monitor?

    This must be where you plug the external monitor with 15 holes. her you would go to the setting on your laptop screen it should automatically detect the new monitor
