My problem is the displayed windows on my monitor/screen

Unfortunately the line didn't show up in the video.

1) New LCD screen?
Should have an Installation CD Disk that comes with it. Use it if so.
Has the Drivers on it.

Driver: Small piece of software that allows the Operating System to communicate with a device.

Don't know which version of the Windows O/S you have.
The device in this case is the LCD monitor.

2) What is the NATIVE screen resolution for the LCD monitor.
Look up the specs on the monitor using it's Model Number on back.

For example I installed an HP 2009M 20-inch widescreen monitor, along with the 26-inch RCA ENV HDTV I use for a monitor.

I had to use the drivers from the disk, but could still not set the native resolution in Display Properties.
There is an alternate resolution to the native one that can be used.
The drivers from the disk made it so.

The 20 inch widescreen is 1600 x 900 (Pixels)
The 26 inch HDTV is set at 1360 x 768 (Pixels)

Right-click on an empty area of your desktop screen.
Left-click on Properties at the bottom of the list.
In the Display Properties window click on the Settings tab.

What is the Screen resolution setting? What is it supposed to be?
The Slider on the line is clicked on with the left mouse button, left mouse button held down; then the Slider is slid to the left to decrease screen resolution, or to the right to increase with the mouse.

Color quality should be set to High (32-bit)

1) Installing software (Drivers) from the Installation disk, (Or from the monitor manufacturers support website);
And,
2) Setting the screen resolution;

doesn't help, replace the monitor cable with a known to be good one.

Still no? Your LCD monitor is going out.

You did not supply vital information, what is brand of your monitor and what is your operating system? Indicated problem suggest display settings error.

I assume that you are running some sort of windows?

1. if comes with monitor installation disk, run it first, reboot the computer
2. check on internet on manufacturer site if they have specific driver for they monitor, if yes, download and run
3. click anywhre on desktop right mouse button
4. select with left mouse button "properties" ("screen resolution" in win7),
5. select display settings
6. adjust settings to proper size and resolution
7. sometime frequency need to be adjusted, if this is the case, got to "advanced" and check several different frequencies available for your monitor (this is true in case of windows xp and older, vista and win7 detect usually frequency automaticaly)

Hope this solved your problem, if you require more detailed instructions, do not hesitate to follow this thread.

control panel - display - settings There is a slide bar on the lower left. slide it to the left and click apply. That will change the size of the display so all you need to do is find out what you like or what the 'native mode' is if you have a lcd monitor. That is the display size it want to have and should be show in the manual.

You may also want to click on advanced which will be to the right of that slide and then makre sure the display adapter has the right drivers. You may want to download and install the drivers directly from the manufacturers website. sometime windows update will install a update and it just doesn;t quite work so best to get the one from the factory if that is the case. Also make sure the monitor is in there correctly. Most major brands will let you download a inf file and make sure the only selections available are those that the monitor can safely handle.

There may have been a software driver for your monitor for windows Vista to set the correct parameters
- here’s what I found on Microsoft’s site but only for Windows 7

https://support.microsoft.com/en-us/help/14108/windows-7-change-screen-resolution

Here’s some info about drivers for monitors on windows vista and 7 :

https://uk.answers.acer.com/app/answers/detail/a_id/4085/~/monitor-driver-installation-in-windows-vista-and-windows-7

In such cases the buttons do not work. Go to start->Control Panel->Display->Settings->Advanced->Monitor->Properties->Drivers. Here you will find an option of Uninstall drivers. Select it. and close all windows. Reboot the PC. Start->Control Panel->System->Hardware->Device Manager->Action->Scan for New HW. Windows will scan for new display and load its drivers. Your display would be alright.

Windows XP and Vista should "auto-detect" the capabilities of this LCD screen.

If not, access http://WindowsUpdate.Microsoft.com
and scan for updates.
When the scan is done, look for "optional hardware" updates.
If Microsoft has a driver, it will be offered for download.

Getting dual monitors to work correctly seems to be a hit or miss affair. In many cases, it's just a matter adding a second video card and monitor and rebooting the computer. In other cases, you need to do some cyber gymnastics to get things working correctly.
The process is the same no matter which version of Windows you are using. First, be sure that your system is working correctly. Boot into safe mode and verify that you have only one video adapter and monitor showing in the Device Manager. If there are more, but you only have one adapter and monitor, you'll need to remove the extras.
Once you're sure that your video setup is working fine, turn off the system and look inside. Remember that you'll need a video card for each monitor that you plan to run under Windows. That means that your system must have a free expansion slot for each one. You may find that you have problems with IRQ sharing or DMA channels, depending on your motherboard and video card, although many video cards seem relatively intolerant of IRQ and DMA conflicts. Install your video card in the appropriate slot, and then connect the monitor.
Restart your system. If all goes well, your computer will boot the same way that it always has…the second monitor will still be dark. If your system prompts you to login, do it. You may need to install drivers for your second video card, depending upon whether or not Windows has built in drivers or not. Just follow the on-screen instructions.
Once the drivers are installed, check the Device Manager to make sure that the display adapter is properly detected:
Once the drivers are installed, open the Display Properties window. In the settings screen, you should see something like this:

You'll see that a second display is shown. Click on the grayed out display marked as "2". The window will change slightly to look like this:

You can then change the desktop resolution and color depth. Once you've done that, click your mouse on the "Extend my Windows desktop onto this monitor" to enable it. Remember that the resolution, color depth and refresh rates of each monitor adapter combination don't have to be the same. The window should look something like this now:
Click on OK and your second monitor should activate itself as an extension of the first:


You'll find that you can change the relative geometries of the two monitors by moving their respective boxes around in the Settings window.

Please reply to me if that doesnt help!!!

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.

This is a problem with the video drivers not the monitor. I would download the newest drivers for your video card, uninstall the current drivers, then install the new ones.
