Yellow screen


There are a variety of problems that can happen to the display monitor of an Acer laptop.
The most common problem is the screen fading or becoming too hard to see.
This can be corrected by adjusting the brightness levels.
Another common problem involves incorrect color, which can be resolved by adjusting the display color settings.
Yet another big problem is the display freezing or appearing jumpy, which can be resolved by updating the display driver.

Hold down the "Fn" key.
Tap the right-arrow key to brighten the display screen.

Tap the left-arrow key to darken the display screen.
Release the "Fn" key to save your display settings.
Color
Right-click on the desktop and click "Graphic Properties."
Adjust the screen resolution by clicking "Display Settings" and choosing a resolution setting from the drop-down menu.
Click "Apply" to check the resolution of the display.
Click "OK" to save the resolution settings.

Adjust the color of the screen by clicking "Color Correction" and moving the brightness or contrast slider to the right or left.
Click "Apply" to check the color resolution of the display.
Click "OK" to save the color settings.

Click "OK" to exit the Graphic Properties application.
Update the Display Driver
Right-click on the desktop. Click "Personalize," "Display Settings" and "Advanced Settings."
Click the "Intel Graphics" tab and choose "Monitor Properties."
Click "Driver."

Click "Update Driver" and choose "Search Automatically."
Click "Install" to install the updated monitor driver. After the driver has been installed, click "OK" to restart the laptop when prompted.
Yellow screen
Yellow tinting in monitors can be caused by either a software calibration issue, bad cables or a worn out display and backlight.
Before you assume that the issue is a hardware one, determine if there are software settings that affect the color or if the cables are working correctly.
After checking these items, and if the yellow tint only occurs on one monitor and you cannot eliminate it, the problem is a display hardware issue and it is less expensive to replace the monitor.

Unplug the power cord from the monitor and replace it with another one.
This is a standard power cord used in printers, monitors and desktop PCs so you can trade it for a cable from another device.
Turn on the PC and monitor to see if the yellow is still there.
Turn off the computer and monitor.
Replace the video cable with another VGA cable from another monitor.
Use one from another computer before going out to buy one.
Restart the computer to see if the yellow tint is gone.
Right click any area on the desktop and click "Properties" from the list of options that appears.
Choose "Display Settings," then "Advanced Settings."
Select "Monitor" and click the "Calibrate Color" button.
Wait to see if the yellow tint goes away.
Locate the temperature color settings on the monitor.
Adjust these to see if there is a change in the color.
A warm color setting will give the screen images more of a yellowish tint.
Click on the "Start" icon, then click "Control Panel" and "System and Security" and choose "Device Driver."
Locate the video driver and click "Update."
Select the option allowing Windows to connect to the Internet to find an updated driver.
Wait for the update to complete in a few minutes.
Expect the yellowing issue to disappear.
Connect the PC to another monitor to see if the same problem occurs.
If the yellow tint does not appear on the newly connected monitor, the problem is a bad backlight or display and the monitor should be replaced with a new one.

How to troubleshoot video issues?


Instruction:
To troubleshoot video issues, follow these steps and test your video after performing each one:
  1. Check the video signal cable connector for bent or missing pins. Check the cable for cuts.

  2. Check to see if moving the monitor connections slightly causes color changes. Tighten loose connections.

  3. In the case of systems with multiple video output connections, verify that the correct connection is being used.
    • Some systems ship with two video connectors on the back, however only one is enabled.
matrix12.jpgExample of a desktop computer equipped with 2 video output connectors.
  1. Standard on board video connection
  2. Optional video adapter connection (some models)
  1. If the monitor has multiple inputs, remove the secondary connections from the computer.

  2. Remove all signal cable extensions and Keyboard, Video, and Mouse (KVM) switch boxes.
    • Use of these devices can result in severely degraded video quality or no video symptoms.

  3. Eliminate wire bundles and magnetic fields from nearby appliances, such as those from speakers, as possible influences on color quality.

  4. If applicable, remove and reseat the video adapter card.

  5. Check to see if the display is visible and check for proper color during startup.

  6. Verify that the video is working by booting to the operating system in Safe Mode.
    • To enter Safe mode press F8 when the Windows logo first appears on the screen during system startup.

  7. Ensure that the most recent video driver has been installed.
    1. Right click on the Windows desktop.
    2. Click Properties.
    3. Click the Settings tab.
    4. Click the Advanced button.
    5. Click the Adapter tab.
    6. Click the Properties button.
    7. Click the Driver tab.
    8. Compare the Driver Version: with the current version and update if needed.
  8. Run the monitor setup program.
    • Some monitors are supplied with setup programs on CD-ROM or diskette. Follow the manufacturers directions.
    • Readability can be improved on some systems by running the Microsoft ClearType tuner.
  9. Check video quality by changing the hardware video adapter to the lowest available resolution.
    1. Right click on the Windows desktop.
    2. Click Properties.
    3. Click the Settings tab.
    4. Use the Screen resolution sliding selector to change resolution.
      The resolution selections available should be limited to the capabilities of the video adapter.
    • Some of the selections available may exceed the monitor capabilities and result in a temporary black screen.
    1. Click OK.
    2. Compare results with other screen resolution selections.

  10. Ensure that the display being used can support the video refresh rate and screen resolution specified in display properties.
    • The manual for your monitor should list the supported refresh rates and screen resolutions.
    • Open the Display Properties dialog box to verify that the refresh rate and screen resolutions are set properly:

      1. In the Properties window, click Settings.
      2. Click Advanced.
      3. Select the Monitor tab to view or change the refresh rate for the monitor.
Notes:
  • Some system boards ship with the AGP slot disabled and plugged. These slots have been disabled at the chipset level and do not work. The plugs should not be removed.
  • Some AGP adapters use a retaining clip, which must be moved to one side to prevent damage when removing the adapter.
  • Setting the video resolution to 640x480x16 colors in Device Manager is not the same as changing the hardware to a VGA adapter. You must change the adapter selection from the installed adapter, i.e. ATI, nVidia, or Matrox, to a standard VGA adapter in the Display Properties dialog box.
  • Some Intel chipsets uses Dynamic Video Memory technology (DVMT) for video memory. The initial memory count can indicate less than expected system memory count.
  • Signal cable extensions and keyboard, video, mouse (KVM) switches are not supported.

Color quality is lowest (4 bit), cannot change also font is very large and I also cannot change.


The video driver is missing or corrupted. Go into Device Manager - Display Adapters - your video card and right click on it and uninstall the driver from there. Reboot , go to the manufacturer of the video chip and download and install a new one.

Medion monitor shows analog out of range and will not turn on


Two options here. 1) Boot into safe mode, open control panel, display, settings, change the screen resolution to the lowest setting and color quality to their lowest setting and reboot. If that works move your setting up to where you used to have it (i.e. 800x600 pixels. Another option is to use System Restore to restore your system to an earlier date...a program you recently installed could be the culprit. System Restore is located at Start, All Programs, Accessories, System Tools.

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!!

Windows has lost the display driver for your particular card. You will need to determine what the card is (it may say when you first start the machine) and redownload the drivers for it.

My monitor is stuck in the lowest resolution


Distorted video after increasing the resolution in Windows. The resolution has been set higher than what is supported by the monitor, ... we recommend 640 x 480 with 256 colors or the lowest available setting.
Computer always boots into Windows safe mode. When booting into safe mode, the lowest settings are used, including your video card. This means that the resolution is 640x480, 16 colors when in safe mode.

Monitor nor driver acknowledged


If you just want to adjust the display settings so that they are more to your liking go to Control Panel and open Display. When the Display Properties box opens click on the settings tab. Use the slider bar in Screen Resolution to adjust to 1024x768 or whatever resolution your monitor displays best at. To the right use the pull down arrow to select the highest color quality you can select. Then click on the Advanced button on the bottom left and you should see a Monitor tab. Click on that and ensure your refresh rate is 60 Hertz. Save your settings, accept the change confirmation when it appears and your monitor should be good to go. I have about 90 Dell LCDs and the default Windows drivers for the LCDs usually work great.
