Screen keeps flashing green-blue-red

The manual for the monitor can be found here (
Mitsubishi DiamondPoint V50LCD User Manual ) The specific Red Green Blue cycle isn't noted.
  1. I'd start with toggling on the on screen set-up display. if that comes up and is legible, then you know that the screen is working.
  2. What is your video set up to push to the V50? If it's not a supported resolution, the display may respond this way. try downgrading it something like VGA (640x480) and see if that works. (The max resolution shown in the manual is 1024 x 768, so don't go higher than that. It's also 24 bit color (8 bits each for R,G,B, so don't try to push 32 bit color to it)>
  3. Set the output to your primary monitor to 1024 x 768, thousands of colors. Make sure the monitor sees it OK. Now you know the first monitor and cable are OK. Now switch the cable to the V50 monitor. Do you get a signal now? Then the display works. Try putting your primary display on the second cable. Does it pick up anything now? No. Maybe a bad cable.
  4. You can try swapping the cable going to the V50 to go from your primary monitor output port on the computer to your primary monitor. if the primary monitor works OK, then the cable is good.
  5. Depending on the computer system you're on, make sure that you at least have a generic monitor driver installed for the V50 output. Ideally, get the driver for the monitor You can get the driver here (
Mitsubishi Monitor drivers ) amongst other places.

Good luck!

Signal out of range, the display can't manage the resolution setting being sent to it by the video card.
- - - - - - > The following applies to Microsoft XP and newer OS a) Try booting into your OS in safe mode. Repeatedly press f8 key as computer starts to power up.
b) Right click on empty area on the desktop and select properties or personalize.
b) Select display settings.
c) Select the lowest resolution and color bit depth available (usually 16 bit).
d) Apply or click OK.
e) Restart CPU.

It should be working now, but mega big & ugly.
Set your monitor resolution to next higher setting. If that works, keep futzing with it till it's to your liking.

Dell E177FPB monitor has ghost images "bleeding"

I had dual monitor with color bleed to the right. The solution was
1) identify optimal resolution for both monitors ( Dell 198wfp @ 1400 x 900) and (Laptop @ 1200 x 800) 2) check colour setting (32 bit or 16 bit) 3) reduce colour setting down to 16 bit) 4) Check performance 5) reduce screen resolution 6) check 7) cycle between screen color and screen resolution 8) if no luck, check updating the drivers for graphic card 9) if no luck, check updating monitor drivers 10) if no luck, check altering memory set aside for graphics (onboard memory for example or off-graphics-chip-on-RAM-memory) 11) Monitor checking software is very helpful : try "" for the Nokia Monitor Test (a CRT tester) or any other freeware/shareware testing program such as passmark's products etc.,
You might just have to suffer with a large workspace and mungy grapics performance though ... I am.

My monitor setting will not stay set on 32bit, it keep on going back to an low 8 bit setting that cause my colors to be off. How can I make this stay on the 32 bit. I have a Phillips 107MB 17 inch/CM2300...

The color bit depth is controlled by your PC Video card, monitor will show what it is being fed with. Please check to see if you have correct video card driver installed in your PC and the video card has enough memory to provide the 32bit color depth.

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.

Monitor color display problem

Go to the control panel. Click on display. The display applet is your next stop. The display applet is your central location for all of your display settings, including resolution, refresh rate, driver info., and color depth. The display applet has 5 tabs: Thmes, Desktop, Screen Saver, Appearance, and Settings. The 5th tab is where you make adjustments that relate directly to your monitor and video card. Look at the Settings tab. At the bottom of the dialog box, you'll see 2 options. Screen Resolution and Color Quality. By moving the Screen Resolution slider, you can change the resolution. The most common resolutions are 640x480, 800x600, 1,024x768, and 1,280x1,024.Your system may have more or fewer resolution options.

The color quality is the number of colors displayed on the screen .You can change the screen resolution with a simple slider and adjust the color depth from 4-bit all the way up to 32-bit color.

Running a 32-bit color gives a nice, realistic tone to images, and many games insist on it.

Clicking the Advance button opens another dialog box with 4 or more tabs.

The monitor tab gives you details about the currently installed monitor and enables you to make changes to the driver and the refresh rate.

After you make your changes to your monitor and it still is not working properly, it must be your video card which is not seated.
In layman term, your video card is not plugged in firmly in the slot!!

Dell M922 monitor problem

To change the resolution back to something more reasonable go to the control panel (start, settings, control panel) and double left click on the Display icon. Click on the settings tab. The color quality should be set a high as possible, usually 32 bit or true color. Then click on the Advanced button in the lower right corner and on the next screen click on the Monitor tab. In the Monitor settings make sure the Screen refresh rate is set between 70 and 75 Hertz (the higher the number the less obvious the screen flicker will be but don?t set any higher). Click on the OK button to go back to the previous screen. Once that is set you want to increase the Screen Resolution using the slider bar to the left. For a 19? screen you would want to set it to a minimum of at least 1024 x 768. The typical setting is 1280 x 1024 depending on monitor / video card capabilities and personal tastes. Once you get the resolution back to the original settings your screen will display as it did before the ?change?. If you find another resolution setting you like better we?ll need to make some adjustments to the monitor itself. Just let us know. Ordinarily screen resolution changes doesn?t just happen, it?s usually the result of a program, user or problem. If that is the case you?ll need to post anther question along with details about what is happening just before the change occurs along with your operating system and any other pertinent information.

Out of frequency means your video card is trying to display a resolution beyond the capability of you monitor. Typically it is really a combination of too high a resolution and too many colors. Typically a 19? CRT will be set to display at a screen resolution of 1024 x 1024 with the color quality at 32 bit or *true* color. Personal preferences differ and you can set it lower or higher, depending on the capabilities of the monitor. Let us know if you have any other questions and please don?t forget to rate this post.
