Try to adjust your computer's display setting, sometimes improper display settings causes that.
Another area to look is to see if you have any "Hot Keys" setup for that corner. Sometimes those corners are setup as shortcut key for doing something. You might have it set without actually knowing.

Dell inspiron mini 910 laptop video has lines and text is hard to read


1) Is the Screen resolution set correctly?

Native screen resolution should be set to 1024 x 600.

Right-click on an empty area of your desktop screen.
Go to the bottom of the list, and click on - Properties
The Display Properties window will come up.

Click on the Settings tab.
Down in the middle of the Display Properties window, you will see Screen resolution in blue.

There is a Slider. In WinXP it is an Arrow, with a Green tip on top, and bottom.
Left-click on the Slider, hold the left mouse button down.

Now move your mouse to the Left, to drag the Slider to Less screen Resolution, or to the Right to Increase.

Stop at 1024 x 600 pixels.

Also the Color quality should be set to Highest (32 bit)

Click on the blue down arrow to the right of the Color quality box.
In the list click on Highest (32 bit)

Go below to the Right, and click on Apply.
Now go below to the Left, and click on OK.

If that doesn't cure the problem, the problem is a hardware issue.
Problem will be;
1) Graphics chipset,
OR,
2) Video Cable,
OR,
3) LCD screen

[The Backlight used is LED backlighting. Uses a series of LED's.
Light Emitting Diode.
There is NO screen Inverter ]

Samsung screen is not calibrated properly. There is a line on the right side of the screen that I can't get rid of.


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.

Montor has colored lines on left side


Are we talking thin vertical lines that run all the way from the top of the screen to the bottom? If so, this usually indicates a failure of the chip controlling that line of pixels.Unfortunately, there is no easy repair for this and the screen will need to be replaced.

Blue vertical line


The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Please rate this if it this helps.
