If your HP 1740 flat panel monitor display looks and acts funny, some simple troubleshooting steps may help. Common problems include a screen that is blurry, too dim or too bright, or shows images that appear off-centre. Any one of these symptoms could spring up from time to time. Resist the urge to replace your monitor. Instead, apply a few solutions to extend its life cycle and squeeze each cent out of your investment.

Skill level:


  1. 1

    Turn off the computer and then verify that the computer cables are connected properly. The DVI-D signal cable must be securely connected to the computer's DVI connector. Alternatively, the VGA to DVI-I cable must be connected securely to the computer's VGA connector.

  2. 2

    Press the "Auto Adjust" button on the front of the monitor if images are blurry, too dark or too light. Alternatively, press the "Menu" button to access the on-screen display menu and move the sliders for brightness and contrast until the image appears clearer. If your flat panel monitor is still not working correctly, go to the next step.

  3. 3

    Adjust the horizontal or vertical image position if the image is not centred. To access the settings, press the "Menu" button, press "Select Image Control" and select "Horizontal" or "Vertical." If your flat panel monitor is still not working correctly, go to the next step.

  4. 4

    Lower the refresh rate or video resolution if an "Out of Range" message appears on the screen. For Windows 7, click the "Start" button, click "Control Panel" and click "Adjust screen resolution" under "Appearance and Personalization."

  5. 5

    Click "Advanced settings," click the "Monitor" tab and click a lower screen refresh rate. Click "Apply" within 15 seconds to keep the changes. If you have another operating system other than Windows 7, please refer to your operating system's "Help" resources or user's manual. If your flat panel monitor is still not working correctly, contact HP support for additional assistance.

Tips and warnings

  • Before you call a service technician or e-mail HP support, collect some pertinent data. Write down the name of your monitor, hardware and main software you are using. Include the model number serial number and purchase date. Describe the problem and any error messages displayed. Even if you do not contact a service technician, it is a good idea to keep a log of computer problems for your own reference.
