1. If you have another monitor try connect it to the VGA port and see if you get a
screen/ if "yes" then your monitor is in need of repair.
2. If "no" then you either have the resolution for your monitor set to high for the display and will need to set it to the proper screen resolution.
3. check the VGA or DVI cable to see if it is seated to the video card properly.
4. Check the VGA/ DVI cable for bent or broken pins.
I hope this helps. Have a great day!

Dimension 4600 no display turn on. HD spins lights lite and can turn off no bios screen display

Change the VGA cable from the monitor, first but sounds like it's the video card that's failed. I would check the monitor with another computer to make sure it's not that.

Monitor is in slef adjust mode how can i turn it off


System setup Disks do not have any relation to your Monitor unless it is an All-In-One PC or a Laptop.

If you can see display when the unit is booting, but not when Windows should be displaying the Desktop, then your Display Size has been set outside of the size limits or refresh rate of the monitor.
An IT Technician could help you boot the PC in Safe Mode to remove the Monitor and let it re-install. This should forward the instructions to Windows to re-detect the monitor and the display limits it has.

If you have no display at any period, try another monitor.

I hope this helps.

When I turn my PC on you can hear it come on but the screen is black.

It sounds like you might have a problem with your video card. If you turn it on and see nothing, not even the gateway logo, than you either have a video card issue or a monitor issue. Hook up the mahine to another monitor to test.

My monitor screen is ok for awhile but suddenly turns a dull yellow color. I just bought it a few months ago.

you must adjust the display settings in the software program that was being used to change the display setting.
  • 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.
  • follw the another steps-
  • 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.
    2. 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.
    3. If the monitor does not work after replacing the cables, replace or service the monitor

    When i turn on my monitor it shows my desktop then shuts off after 10 seconds...never stays on

    elainenemeth, Hi, Tell me more! How old is this LCD monitor? Is it out of warranty? Did the "SHUT-DOWN-IMMEDIATE" problem occur without warning? Did the BenQ display a "perfect" image the day before? Did you actually count----1001, 1002----1010 and then it shut down, after pushing the monitor on button. Did you do the "flashlight" test? With monitor connected to a "known-good", fully booted pc with Win Desktop displayed, TURN ON the monitor! Did it display the desktop for 1-2-10 seconds ? What did you see or not see when you pointed the flashlight at different angles about 1-2" inches from the now dark (black) screen? Get back to me with your results. I will offer the best advice possible to you as a consumer/user of LCD/FPD monitor. I'm louie12fix on fixya or lmistyrel @ Bye for now.

    HP desktop monitor problem

    hi try this ,,,
    1. Ensure the video cable is connected (and connected to the correct video port).
    2. Turn off the monitor using the monitor's power button and then restart the monitor.
    3. Cycle the power on the monitor as follows:
    4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
    5. Unplug the power cord.
    6. Wait 5 seconds.
    7. Plug in the power cord.
    8. 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
      3. 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.
        hope it will work for u .. little_angel
