Optiplex 745 monitor goes to sleep randomly


In regards to your issue with your monitor: For a monitor to display "no signal input" there is likely a problem with the monitor making a connection to your input source (yes I know duh). First and easiest thing to fix this is to check your cables going between your computer and monitor, if your computer and monitor start out working and then fail to communicate, there is a good chance that the cable might be coming loose just enough that the connection fails. I might suggest that if you have, as you say another computer, that you try swapping monitors to check where the problem lies.

Hope this helps some.

Boots up without images on the screen


The graphics card in the PC is very likely faulty. It is possible to remove the graphics card and reconnect the monitor cable to the onboard graphics. Look on youtube for help on removing the graphics card (try a search for iq772). The monitor connector is at the front of the motherboard, near to the graphics card. re-connect it to a similar connector to the left to use the on-board graphics.

My screen is blank when I turn the computer on?


If you have recently connected a second monitor, and have since disconnected the second screen, the primary screen will be completely black. Restart your computer and this should fix it. If it continues, your screen may have over-heated, in which case it needs complete replacement, or it may need to cool down.

If you have an LCD screen, check the power cable connections on the back of your sceen making sure they are connecting properly. If all is connected and you have tried to restart - your screen will need to be replaced.

Monitor is switching off immediately after system is switched on. Again when monitor is switched on, images appear for about 3 seconds and again monitor switches off.pl give the solution.


You need to determine if you is turning off or going into standby mode. When your monitor shuts off, the power light will turn orange if it is in standby or the light will turn completely off if the monitor turns off. If your monitor goes to standby, that means that your monitor is losing signal which indicates a problem with your PC. #1 Make sure cable is firmly secured and both screws are tight #2 Check your video card make sure that it is firmly in its slot. Take it out and put it back in. *as long as your computer is open give it a good cleaning with compressed air* If those things check out it is possible that your video card has failed and needs to be replaced.
If your monitor is powering off #1Check plugins- try something else (i.e. lamp) in the outlet #2 Try your PC's power cord in your monitor

    I have an hp pavilion dv5. When I power it on the computer starts up but the monitor doesn't come on. And then it does this series of beeps. Beep beep beep. It does that series 5 times


    Before you begin
    Check the following items before using the steps in this document:
    •If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
    •Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
    •If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
    •Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
    With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
    Step 1: Connect the computer to another monitor
    Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
    After the monitor is connected, turn on the computer and the monitor. What happens?
    •If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
    •If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
    •If the new monitor works , the original monitor or its cables are faulty. Do the following:
    1.Replace the monitor power cable.
    1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    1.Replace the video cable.
    Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    1.If the monitor does not work after replacing the cables, replace or service the monitor.
    Step 2: Is the video connection damaged?
    Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
    Figure 1: Video connector
    If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
    Step 3: Resetting and updating the BIOS
    You can use these steps even though you will not be able to see anything on the monitor.
    In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
    1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
    ◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
    ◦For HP and Compaq computers that came with Windows XP, press F1 .
    ◦For Compaq Presario desktop computers built prior to 2002, press F10 .
    1.Wait another 5 seconds.
    1.Press the F5 key. This restores the default settings of the BIOS.
    1.Press the Enter key. This accepts the changes.
    1.Press the F10 key. This saves the changes.
    1.Press the Enter key. This saves the changes and exits from the BIOS.
    1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
    1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

    NO SIGNAL What do I do?


    These messages are normal when the computer truly goes into suspend mode or loses the video signal (such as when the computer is suddenly turned off).
    If the monitor displays any of these messages when the computer should be displaying video , do the following items until an image from the computer appears:

    1.
    Ensure the computer is really sending a video signal. To bring the computer out of suspend mode: move the mouse, press the spacebar, and press the suspend button on the keyboard twice (the suspend button has an icon that looks like a quarter moon).
    2.
    Ensure the video cable is connected (and connected to the correct video port).
    3.
    If you are trying to view video from a set-top box, DVD player or similar device, use its menu system to set the proper video output channel so that it matches the video connection are using. For example, if the monitor is connected to a satellite receiver via a second HDMI connection on the back of the receiver, select HDMI-2 (or similar) using the remote control for the receiver.
    4.
    Turn off the monitor using the monitor's power button and then restart the monitor.
    5.
    Cycle the power on the monitor as follows:
    1.
    Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
    2.
    Unplug the power cord.
    3.
    Wait 5 seconds.
    4.
    Plug in the power cord.
    5.
    Press the power button on the monitor to turn on the monitor.
    One of two things happens:
    1.
    The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2.
    The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution.
    6.
    Adjust the Windows display resolution to a setting that is compatible with the monitor:
    NOTE: The native resolution setting for your model of monitor can be found in the Monitor User Guide, the monitor's product packaging, and product specifications.
    1.
    Restart the computer and press F8 repeatedly after the first logo screen.
    2.
    Select Safe Mode .
    3.
    Windows should open showing a Windows desktop with lower resolution and fewer colors.
    4.
    In Windows Vista, click Start , Control Panel , and click Adjust Screen Resolution in Appearance and Personalization.
    In Windows XP, click Start , Settings , Control Panel and then double-click the Display icon and select the Settings tab.
    5.
    Move the slider bar until the native resolution for the monitor is set, click OK and restart the computer.
    6.
    If the native resolution is not available from the slider bar, click Advanced Settings , click List All Modes (from the Adapter tab), select the resolution, and click OK .
    If the native resolution setting is not available as a selection in Windows, you can temporarily use 1024 x 768 to complete these steps. However, you should update the graphics driver on the computer. Updating the graphics driver can provide more display resolutions to Windows; possibly including the native display resolution for the monitor.
    *
    Check for nVidia video driver updates at nVidia Home Page (in English).
    *
    Check for ATI video driver updates at ATI Home Page (in English).
    *
    Check for S3 video driver updates at S3 Graphics Home Page (in English).
    *
    Check for Intel video support and downloads, Intel Downloads (in English).
    *
    If you own an HP or Compaq computer, HP hosts video drivers and some video driver updates at the HP Software and Drivers site (in English)
    7.
    Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
    *
    If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
    *
    If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
