    I am having the same problem. When I disabled the NVIDIA card because of some errors my computer started using VGA display but then i disabled it thinking it would re-enable the NVIDIA display but now the only thing i get after the XP logo is a blank screen. The blank screen appears but the computer seems to be running because i can hear the startup sounds and etc. In this case I have a Dell Dimension 8200 desktop. I already tried going into the BIOS menu to try and re-enable VGA but there is no option. Please help me out.

By default Windows XP displays the Graphic login screen with icons and usernames at startup.

If you would like to use the more traditional Windows NT login screen you can get to that screen by pressing Ctrl Alt Del (Reboot key sequence) twice.

If you would like to change to the traditional screen at login, instead of the graphic login screen, do the following:

  1. Log in with administrator access.
  2. Click on Start, Control Panel, and select user accounts.
  3. Click on Change the Way Users Log On or Off.
  4. Click on the Box "Use the Welcome Screen" so that there is not check mark.
If you would like to switch from the traditional login screen to the more graphic screen just click on the box in step 4 above so the "Use the Welcome Screen" box is checked

On my HP Compaq nc5220 The computer is working and the screen on the monitor is some what 'lit up' but after the initial start up and the Windows HP logo comes across that is it. It will not proceed to...


For that you need to change screen resolution settings in display property.
When you power up the computer press F8 key 5 to 6 times then you can see safe mode and other menu then enter in "enable vga mode" then go to start menu ->control panel->display->settings.
Change screen resolution to 1024*768 then apply and ok.
Then check.
If you are not able to enter in enable vga mode then enter in safe mode and uninstall graphic driver then reinstall driver then it will work.
Let me know if you need further assistance.

''help me i got a windows problem''


the most likely problem is that your display drivers crashed,start your pc press f8 you'll get black screen with options select enable vga then it will start up,when the desktop opens go to control panel and un-install the display drivers first,reboot,and then reinstall them,hope that works.

Acer notebook VGA problem


Not sure about your model as the header is Dell D600 and you mention Acer but the solution is probably the same. You need to enable the 2nd display - I'm assuming you are running XP. Go to display settings -easiest way is to Right click on the desktop, bringing the display menu and Left click on Properties (bottom entry). Then click on Settings and you should see 2 screens and you will need to enable the 2nd monitor and set up how to display on it. Additionally there is a setting in the BIOS that enables both display outputs.

Trying to connect Inspiron 6000 to TV



If there is no display on your TV, HDTV, or Projector, please make sure that all of your connections are set up properly and that you have enabled the display in the Catalyst Control Center. The connectors that you will be using would be Svideo for TVOUT, DVI-to-HDTV (Component video), VGA-to-HDTV (Component video) for HDTV, and DVI, VGA, or Svideo for the projector.
737-22474-1.jpg Here are the steps to properly setup and enable TV, HDTV, or Projector:
  • Turn off your PC and your TV, HDTV, or Projector.
  • Ensure that your card was installed correctly, as per the Getting Started Guide.
  • Determine if your TV, HDTV, or Projector has a S-Video (for TV), YPbPr for (HDTV), or VGA/DVI for Projector.
  • Looking at the back of your PC, locate the needed connector or the supplied adapter cable; attach one end of the cable to your graphics card and the other to your second display.
  • Turn on your second display then your PC.
If you are connecting an HDTV to your video card, please Click here for detailed instructions on how to set it up correctly.
Starting Windows with TV or Projector Display Enabled The TV screen may become scrambled during the initial Windows® logo display. This is only a temporary effect and your screen will be restored within a few seconds. During start up, your RADEON will go through a sequence of mode settings, during which your TV display will remain blank. This process takes only a few seconds and helps program the TV display.
  • To enable the second Display
  • Right-click anywhere on your desktop
  • Click Catalyst Control center
  • View
  • Advanced view
  • Display manager
  • Detect Displays
  • You should have the second display picture under “Attached displays currently disabled
  • Drag it to the box on top of it
  • Apply
  • OK
If for any reason the second display does not get detected, please do the following:
  • Open the CATALYST CONTROL CENTER
  • Go to Display options
  • Check “Force TV detection” *
  • Apply
  • OK
* Force TV: Allows you to force TV detection if the ATI driver does not automatically detect TV-out connected to the graphics accelerator.
Possible issues:
In case the users display does not natively support HDTV display timings in the EDID, you can add standard HDTV modes so that the usual HDTV resolutions (720p, 1080i, 1080p) are listed in the Display Manager resolutions. You can also create custom HDTV timings to solve any kind of over-scan options (for cases when the windows desktop appears to not fit on the HDTV screen, and the outside boarder is cut off).
For more information on connecting your second display to your Video card, including supported output device combinations, please refer to your user’s manual.
