The problem of my Acer TravelMate 3270 is no display in the LCD Monitor even the computer is power on & completely loading the OS. I tried to connect an external monitor thru the vga port but no...


Hi there,

Did you make any hardware or software changes in your computer after which this is happening?
Which is your operating system?
Do you see Black screen after os loads up? if yes then its a black screen error.

A black screen may occur if there is a problem with the video card drivers and Windows 7. To resolve this problem please follow these steps:

1. Restart the computer.
2. Press the F8 key before it enters Windows.
3. Select the Safe Mode option in the Advanced Boot Options menu and press Enter.

NOTE: If Safe Mode does not work please retry the first two steps and select the Enable low-resolution video (640x480) option instead. If this option is selected your desktop will be bigger than usual - this is by design.

4.
Once in your desktop, click on Start and select the Control Panel.
5. Select the Hardware and Sound option and then click on Device Manager under Devices and Printers.
6. Expand the Display adapters list - this should display the video card that is currently installed on your computer. Please note the make and model before proceeding.
7. Right click the video card under Display Adapters and select Disable.
8. Repeat this step if more than one video card is showing under Display Adapters.
9. Once all display adapters have been disabled restart the computer in normal mode.

At this point you should be able to get into your computer without a problem; however, your video card is disabled so you will need to download and install the latest drivers for it. If you had noted the make and model of card when you were in the device manager you can search for this on the internet and/or contact the hardware manufacturer for help. Once the drivers are installed correctly on the system you should be able to boot normally without any resolution problems.

Post back we will be happy to help you.

Hope this helps.

Cheers!!!

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.
Thanks for using FixYa.

My sound is not working its been turn off and I can't fix it. The icon at the bottom of screen is showing an x on sound icon when I try to fix it it say no sound device on computer.


You need to reinstall your sound card drivers. This software driver is available in your CD installer shipped with your laptop. Try to look for it and install it and see if your laptop will have sound.

Also, before trying to reinstall your sound driver, it is also logical if you could check if it is just "disabled" in the device manager. If you can enable it, it should fix your problem the easiest way.

  1. Right click on your "My Computer" icon on your desktop and click "Properties"
  2. Click on the Hardware Tab
  3. Click the "Device Manager" button.
  4. On the "Device Manager" window, click on the plus "+" sign near "Sound, video and game controllers".
  5. Make sure that NO sound device is disabled. If there is, ENABLE it. (Click it to select then click the "enable" button above.

Screen display size on Thinkpad A22p


your system might have damaged the systems video drivers and reverted to legacy.
try to re-install the display drivers again.
if you look in the system/device manager for the display it may just say vga , which can only give you 800x600 native mode.
if you right click on the desktop /properties
advanced /display adapter it should have the name of your video card.

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.
