Question about Mitsubishi Diamond Computers & Internet

Open Question

Screen image sporadically changes between 2 sizes.

For a given resolution setting the image size varies from a normal 100% to about 85% size. This happens particularly on startup or when screen goes from screensaver powerdown to active. When the screen shrinks it always brightens significantly and black levels become poor. It will switch back and forth between these 2 states (100%/normal and 85%/too bright) about evry 15 seconds to 2 minutes until the screen has been on for 1/2 hour to one hour. What is the defect and how can this be repaired. This is an otherwise very satisfactory monitor and I don't want to ditch it.

SOURCE: Screen goes black with white horizontal line.

WHEN does this problem occur? Does it ONLY happen after the computer loads Windows (or another OS), or does it happen as soon as you turn the monitor on? We really need more information before we can provide specific advice or suggestions... IF this happens as soon as you turn the monitor on, switch it with a different monitor. If the problem goes away, the original monitor is defective, and probably not worth the cost of repairing it. If the problem ONLY happens after you load Windows, boot the system into Safe Mode (press the F8 key during bootup until you see the menu which allows you to select Safe Mode), then reboot and see if the problem has been resolved; simply booting into Safe Mode, then rebooting the system into Windows MIGHT solve this WITHOUT requiring you to change any system settings... IF the problem remains in Windows AFTER you've booted into Safe Mode AND rebooted back to Windows, the videocard driver might be corrupted. In that case, you'll have to reinstall the vidcard driver to correct this problem... If all else fails, it IS possible that the videocard itself is defective; if installing an updated driver doesn't work, try swapping the videocard with a different one. BE SURE to uninstall the OLD videodriver, and install the proper one for the new videocard; if you don't install the correct driver, you could create MORE problems than you have right now...

SOURCE: C840 resolution difficulties...

The type of screen you have is a UXGA screen. the optimal resolution for that is 1600 x 1200. changing the resolution for that will distort the screen causing black borders. If a computer has a 15.0+" SXGA+ screen with an optimized resolution of 1400x1050 and the screen's current resolution is set to 1280x1024 pixels, the display will shrink resulting in a black border surrounding the edges of the screen. Also, all other lower resolutions may be stretched to fit the screen. No border will be visible, but fonts may appear slightly fuzzy.

SOURCE: Image appears for 2-3 seconds then screen goes black

The following steps are how to examine what's wrong with your LCD monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,
Tan

SOURCE: Screen shrinks monentarily then zooms in untill screen is blank, then turns off.

I had a similiar issue that caused all my Microsoft applications to zoom out to 500%. It also caused PDF documents to shrink and go the the last page. The issue was caused by the Intellatype software that came with my ergonomic keyboard. The issue was resolved by disabling the zoom feature of the sofware on the zoom tab.

Check connections, Hertz rate, and settings (if you can read them). Otherwise, it may be time to whip out the cash and get a new monitor and/or computer.

How do I make my screen size on my computer smaller. Too big for the size of my comp.


Right click on the desktop and select Properties right at the bottom of the pop-up menu. Then a "Display Properties" window will open. Click on Settings. In this tab you should see a slider bar with the title "Screen resolution", (drag this to the right to make the screen more detailed/smaller and your icons smaller) or (drag it to the left to make the icons larger and the screen size less detailed/larger). Then hit Apply.

NB: If your screen goes blank it means that your display card cannot handle the given resolution. If this happens immediatelly hold down the"Enter" key on your keyboard until the display comes back. Then try a lower resolution.

Please rate me high.
Thanks.

How to use change resolution


Hi,

The screen resolution of the Camera cannot be changed. The option in the Camera is to change the Image size which will increase the MegaPixel rate of the Camera. This can also be called as resolution. This can be changed by touching the Image Size icon displayed on the Camera screen. The settings available for Still Image Settings and Movie Image Settings in the DSCT70 Camera are given in the image given below:

Images scan set at 300 dpi, end up 72 dpi


It depends on the physical size of the images. Size and resolution are related to each other. Let me explain:
You have an original, say, 2 inches by 2 inches.
You scan it with resolution of 300dpi (dots per inch).
You will get a file that's 600 by 600 pixels, right?
Then you look at it on screen, which has a resolution of 72dpi - if it's displayed without magnification, what size the picture will be? 600 divided by 72 = 8 and 1/3 of an inch, so on screen it will be 8 1/3 by 8 1/3 inches.

So, there's no such thing as a picture file's "real" resolution - we can talk about a resolution at a given size, because it's the horizontal and vertical size in pixels what's "real".

Therefore you have to ask what size the scanned picture is, and then look at the file you receive; in it's properties you will find it's number of pixels horizontally and vertically, and from that you can easily calculate (dividing the height in pixels by the height in inches) the actual resolution the file has been scanned at.
Then you'll know for sure if need to complain to the friend ot not :)

My HP monitor (f50) has malfunctioned


Try these 2 steps if they don't work get back to me :)

Step 1. Connect the video cable and turn on the computer. What happens?
  • If the monitor screen remains blank (no startup screens or onscreen display messages), the monitor must be connected to another computer using a different cable to determine if the monitor is bad. Skip to the Step to connect the monitor to another computer.
  • If the monitor is capable of displaying boot screens but is unable to display Windows, use the following steps to set the computer to a compatible resolution:
    NOTE: Find the native display resolution for your monitor in the User Manual or in the product specifications for the monitor model. If you are unable to find the native display resolution for your monitor model, temporarily use 1024x768 for troubleshooting purposes.
    1. Turn on the computer and press the F8 key repeatedly when the first startup screen appears.
    2. If you are using Windows Vista, select Enable low resolution video (640 x 480) , press Enter , and wait until Windows opens. To set display settings that match the monitor, use the steps in the HP support document, Changing Display Settings, Background Image, and Screen Saver in Windows Vista . If you are using Windows XP, select Enable VGA Mode , press Enter , and wait until Windows opens. Continue using these steps to set display resolution. If you are using Windows 98 or ME, select Safe Mode and perform the following steps to enter into a standard VGA mode:
      1. Once Windows opens to the desktop in Safe Mode, click Start , and Run .
      2. In the Open field type msconfig and press Enter . The MS Configuration Utility window appears.
      3. Click the Advanced button, and select VGA 640 x 480 x 16 if it is available.
      4. Click OK and restart the computer.
      5. After Windows opens, click Start , and then click Run .
      6. In the Open field type msconfig and press Enter .
      7. Click the Advanced button, and remove the checkmark next to VGA 640 x 480 x 16 .
      8. Click OK . Do NOT restart the computer.
    3. After Windows opens, right-click on an open area of the desktop and select Properties (Windows XP, 98/Me) or Personalize (Windows Vista).
    4. In Windows Vista, Scroll down and click Display Properties . In Windows XP, 98, or Me, click the Settings tab.
    5. In Windows Vista, select the native display resolution size using the Resolution slider. Set Colors to Highest (32 bit) . In Windows XP, select the native display resolution size using the Screen resolution slider. Set Color Quality to Highest (32 bit) . In Windows 98 or Me, select the native display resolution size using the Screen Area slider. Set Colors to True Color .
    6. Click Apply after you have made your adjustment. The screen should blank out temporarily and come back.
    7. If you are satisfied with the new display settings, click Yes on the Monitor Settings windows. If you are not satisfied or if the screen just goes black, wait: Windows sets the screen back to the way it was before. Try another setting until you find a display configuration that is compatible with the monitor and meets your needs.
      NOTE: If the native resolution is not available, download and install updated video driver software for your computer. Updating the video driver software can add more resolutions (graphics modes).
    8. Restart the computer. The monitor should now display a full screen image in high quality. You are done.
Step 2: Connect to another monitor
Using a different cable, connect the monitor to another computer that has video. Turn on the monitor and the newly connected computer. What happens?
  • If the monitor works, the video hardware on the original computer is likely to be the source of the problems. You can try connecting the original computer to another monitor that works to update its video drivers.
  • If the monitor remains blank, repair or replace the monitor.

No Signal when desktop wants to load


It does not hate that monitor. I believe the problem is in the settings on your video. Your monitor cannot display them. You will most likely need to start your computer in safe mode and change the display settings on your video card or, alternatively, download updated video drivers. Also, if you can't get Windows to start in normal or safe mode, one of the options you get when you press F8 on startup is to start in VGA mode. That will get you in so you can tweak your settings, which are probably set to a resolution too high for your monitor.

Try changing the keystone. Also you may have the projector too far away from the screen. Changing the resolution on your laptop will not solve that particular problem.
