Re: distorted picture

It's possible your video card or monitor is going bad. Which type of monitor do you have? If it's a CRT then my guess is....monitor.
Check all your cables and connections first.
If possible hook up a known working monitor to rule out memory or video card problems.Monitors have a refresh rate but I don't
recommend doing this without supervision or complete knowledge.
Check to make sure you don't have any interference close to your monitor. Interference would/could be: magnets/speakers/radio's/televisions/microwaves (not sure about micros.
If your have a LCD monitor I'm not sure all these suggestions apply.

How do i enlarge the print on the screen

there are several things you can do, change the screen resolution, or change the size of the text, to do this go to Control Panel - Appearance and Personalization - Display then click the 125% radio button and apply. in versions of windows older than windows 7, this process may be slightly different, this option may be in the ease of access centre. if you have trouble changing either of these things type your operating system and change screen resolution or change text size into google. to change the screen resolution go to control panel and in appearance and personalisation click adjust screen resolution, this will make everything look bigger, try to keep near the same aspect ratio or photos and text will look distorted or stretched.

My monitor suddenly has become distorted. It appears scrunched horizontally, from both the right and left sides. The whole monitor image is visible, but it is distorted. I have checked the cables, reset...

Try connecting the monitor to a different computer (desktop/laptop).

If the symptoms persist, it's time to responsibly recycle the CRT, and to replace it with a 19-inch LCD monitor.

Signal outof range

  • Make sure the pins on the video cable are not bent or damaged.
  • Make sure there are no extension cables or switch boxes attached to the monitor.
  • Verify that you have the proper drivers installed for the video card.
  • Verify the problem at all possible resolutions and refresh rates.
  • Make sure the refresh rate does not exceed maximum value for any resolution.
  • Test the monitor on a different computer.
  • Contrast is recommended to be set at a higher range while the brightness should be set at middle range. This helps to increase the text clarity while reducing the bright background.
  • If your monitor is equipped with moire control, adjusting this may improve the clarity of the text. Moire is a wavy distortion pattern caused by interference between the dot pitch of the CRT and the picture signal. The pattern may vary depending on the screen amplitude, contrast, brightness, and other characteristics of the input signal.
  • Monitor's performance may be affected by the Earth's magnetic field. Try rotating the monitor to different directions to improve misconvergence.
  • Most video cards offer a software utility that changes the frequencies and sync polarities for all resolutions. If the setup does not match with the monitor's characteristics, an incorrect signal may be displayed on the screen. Sometimes, the image may also appear blurry.

    I have an HP 2009m monitor. When I try to have

    The problem is that your picture is not of high enough resolution. You need to get a higher resolution picture. There is nothing wrong with the monitor. The picture is distorted because the picture does not contain enough photographic data to scale to the size you are stretching it to. Higher resolution = larger picture without distortion.

    this sounds like an electrical fault or failing component, within the Monitor.

    Check the cabling, to ensure it,s not damaged-broken-kinked et,c. by carefully moving the cable gently side to side and up and down.
    If it puts itself right for a second or two. you can assume its a broken internal wire, within the lead.
    Or a dry soldered joint-Connection.

    "Waves" generating from the right of the screen.

    It's power distortion. If you move the monitor away from the pc, the waves will stop. It's magnetic distortion causing this interference. Your monitor is fine.

    Screen Distortion at certain Refresh Rates

    Have you connected the laptop to another monitor and use the same refresh rates that cause the distortion? If the distortion appears on a different monitor, then I would have your laptop examined by a pc engineer, but, if the distortion only appears on the 997DF monitor, I suggest having the monitor checked at a repair shop, also, have you tried connecting the 997DF to a desktop PC, and use the same refresh rates?
