You PC may have dual display capability. Try booting into safe mode by pressing F4 or F8 key at start up. It will give you some options one of witch is start in safe mode. Save mode should have the desk top screen. Right click the desk top anywhere, but not on a icon, choose graphics properties for the drop down menu. You should find a section that says Display Devices or Display 1, Display 2 or something like that. Make sure the PC set to use Display 1 or Single Display and reboot the PC back in normal mode.
There are other thing that can cause your problem, but this is one of the more common ones.

Hope I was helpful.
Good Luck

This is because of your laptop operating system.
You need to reinstall the operating system.(Windows XP,Vista ,Windows 7,Mac Os,Linux)
How to install windows XP Professional?

The best way install Windows XP is to do a clean install. It is not difficult to perform a clean installation. Before you perform the installation I recommend that you check Windows XP Compatibility List to ensure that your hardware is supported by XP.
If your hardware is not on the compatibility list you can check your hardware manufactures website to download the drivers for Windows XP. Save all the necessary drivers onto floppy disks or CD before you start the installation.
All versions of Windows XP CD are bootable. In order to boot from CD/DVD-ROM you need to set the boot sequence. Look for the boot sequence under your BIOS setup and make sure that the first boot device is set to CD/DVD-ROM. You can then perform the following steps to install Windows XP:
1. Start your PC and place your Windows XP CD in your CD/DVD-ROM drive. Your PC should automatically detect the CD and you will get a message saying "Press any key to boot from CD".
After your press any key ,on the screen will apear this message:"Setup is inspecting your computer's harware configuration..."
2.At this stage it will ask you to press F6 if you want to install a third party Raid or SCSI driver. If you are using a an IDE Hard Drive then you do not need to press F6. If you are using a SCSI or SATA Hard drive then you must press F6 otherwise Windows will not detect your Hard Drive during the installation. Please make sure you have the Raid drivers on a floppy disk. Normally the drivers are supplied on a CD which you can copy to a floppy disk ready to be installed. If you are not sure how to do this then please read your motherboard manuals for more information.
3.You will then get a Windows XP Professional Setup screen. You have the option to do a new Windows install, Repair previous install or quit. Since we are doing a new install we just press Enter to continue.
4.You will be presented with the End User Licensing Agreement. Press F8 to accept and continue.
5. This step is very important. Here we will create the partition where Windows will be installed. If you have a brand new unformatted drive you will get a screen similar to below. In our case the drive size is 8190MB. We can choose to install Windows in this drive without creating a partition, hence use the entire size of the drive. If you wish to do this you can just press enter and Windows will automatically partition and format the drive as one large drive.

However for this demonstration I will create two partition. The first partition will be 6000MB (C: drive) and second partition would be 2180MB (E: drive). By creating two partition we can have one which stores Windows and Applications and the other which stores our data. So in the future if anything goes wrong with our Windows install such as virus or spyware we can re-install Windows on C: drive and our data on E: drive will not be touched. Please note you can choose whatever size partition your like. For example if you have 500GB hard drive you can have two partition of 250GB each.

Press C to create a partition.

6. Windows will show the total size of the hard drive and ask you how much you want to allocate for the partition you are about to create. I will choose 6000MB. You will then get the screen below. Notice it shows C: Partition 1 followed by the size 6000 MB. This indicates the partition has been created. We still have an unpartitioned space of 2189MB. Next highlight the unpartitioned space by pressing down the arrow key. Then press C to create another partition. You will see the total space available for the new partition. Just choose all the space left over, in our case 2180MB.

7.Now you will see both partition listed. Partition 1 (C: Drive) 6000MB and Partition 2 (E: Drive) 2180MB. You will also have 8MB of unpartitioned space. Don't worry about that. Just leave it how its is. Windows normally has some unpartitioned space. You might wonder what happened to D: drive. Windows has automatically allocated D: drive to CD/DVD-ROM.

Select Partition 1 (C: Drive) and press Enter.

8. Choose format the partition using NTFS file system.This is the recommended file system. If the hard drive has been formatted before then you can choose quick NTFS format. We chose NTFS because it offers many security features, supports larger drive size, and bigger size files.

9.Windows will now start formatting drive C: and start copying setup files .

10.After the setup has completed copying the files the computer will restart. Leave the XP CD in the drive but this time DO NOT press any key when the message "Press any key to boot from CD" is displayed. In few seconds setup will continue. Windows XP Setup wizard will guide you through the setup process of gathering information about your computer.

11.Choose your region and language.

12.Type in your name and organization

13.Enter your product key.

14.Name the computer, and enter an Administrator password. Don't forget to write down your Administrator password.

15. Enter the correct date, time and choose your time zone

16.For the network setting choose typical and press next

17.Choose workgroup or domain name. If you are not a member of a domain then leave the default settings and press next. Windows will restart again and adjust the display.

18.Finally Windows will start and present you with a Welcome screen. Click next to continue.

19.Choose 'help protect my PC by turning on automatic updates now' and press next.

20.Will this computer connect to the internet directly, or through a network? If you are connected to a router or LAN then choose: 'Yes, this computer will connect through a local area network or home network'. If you have dial up modem choose: 'No, this computer will connect directly to the internet'. Then click Next.

21.Ready to activate Windows? Choose yes if you wish to active Windows over the internet now. Choose no if you want to activate Windows at a later stage

22. Add users that will sign on to this computer and click next.

23.You will get a Thank you screen to confirm setup is complete. Click finish.

24. Log in, to your PC for the first time.

25.You now need to check the device manager to confirm that all the drivers has been loaded or if there are any conflicts. From the start menu select Start -> Settings -> Control Panel. Click on the System icon and then from the System Properties window select the Hardware tab, then click on Device Manager.

26.If there are any yellow exclamation mark "!" next to any of the listed device, it means that no drivers or incorrect drivers has been loaded for that device. In our case we have a Video Controller (VGA card) which has no drivers installed.

Drivers for ASUS VS229 IPS HDMI


It's possible, but it sounds more like a power saving feature is set up incorrectly. A computer monitor can be set to go dark after a specified time in these places:

  1. In the settings of the monitor itself, accessed by buttons on the monitor. Check the timeout setting.
  2. In the computer's operating system power settings. If you're using the Windows operating system, check the advanced power settings to see how long the screen will stay active when the computer is idle.
  3. In the display drivers for the computer. If you have special display drivers installed, there will be a settings application in your system. The most common ones to look for are Nvidia and ATI.
  4. In the computer's BIOS settings. This is probably not where your problem is, but you can access the BIOS settings by pressing Delete or F2 when the computer is first starting up. If you press the Escape key when the computer starts up, you should see a message that tells you how to enter the BIOS settings. Then look for a power saving feature that sets how soon to time out your display when it's idle.

I hope that helps you!

Por error desconcete el sonido del monitor y no


My Dell monitor screen goes black after I move my mouse around to get on my computer. The screen goes black and I have to hit the button on the screen (that lights up the screen) about 18 times until it finally stays lite. I don't get it, if there is a problem with the light why does it stay on after hitting the light button several times?

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

If you did not hear any beep from your CPU, then the problem is in the system not the screen.

You'll find out that either the screen or the computer...
