(what appears to be) color pixels on computer screen

As of this evening, there are purple and red pixels (in the form of lines and dots) on my monitor screen, whenever there is either a photo or graphics. These pixels often appear along a line in the photo or graphics. I am not sure if the problem is with the monitor or the desktop (Dell Dimension 8300). I have tried to adjust color, tried a virus scan, and tried a RegCure scan. Nothing has helped.

Hi shaidan .... start by updating your graphics card drivers.... if there is no change then reduce your resolution and see if that effects it.... are there alot of bad pixels as it is normal for an LCD display to have a few bad pixels...

Tip

"Aero features are'nt running in window's 7"


Solution: Check that your computer meets the minimum hardware requirements for running Aero:



1-gigahertz (GHz) 32-bit (x86) or 64-bit (x64) processor


1 gigabyte (GB) of random access memory (RAM)


128-megabyte (MB) graphics card


Aero also requires a DirectX 9 class graphics processor that supports a Windows Display Driver Model Driver, Pixel Shader 2.0 in hardware, and 32 bits per pixel.

For best results, you might also want to follow these graphics processor recommendations:



64 MB of graphics memory to support a single monitor with a resolution that is less than 1,310,720 pixels (for example, a 17–inch flat panel LCD monitor that has a 1280 × 1024 resolution)


128 MB of graphics memory to support a single monitor with a resolution from 1,310,720 to 2,304,000 pixels (for example, a 21.1–inch flat panel LCD monitor that has up to a 1600 × 1200 resolution)


256 MB of graphics memory to support a single monitor with a resolution greater than 2,304,000 pixels (for example, a 30–inch wide-screen flat panel LCD monitor that has up to a 2560 × 1600 resolution)


To turn on window frame transparency, the color scheme must first be set to Windows Aero.

1.Open Personalization by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Appearance and Personalization, and then clicking Personalization.


2.Click Window Color and Appearance.


3.Select the Enable transparency check box.

To change the color scheme to Windows Aero

1.Open Appearance Settings by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Appearance and Personalization, clicking Personalization, and then clicking Window Color and Appearance. If the Appearance Settings dialog box is not displayed, at the bottom of the page, click Open classic appearance properties.


2.In the Color scheme list, click Windows Aero, and then click OK.

Check that your theme is an aero theme and not a normal theme. Themes are available in normal and aero and can be confusing. Set your theme as an aero theme and you should get the aero window working.

These steps will help us to have AERO running.

Thank's and Regard's:

Acer monitor has green lines on the scren


Liquid Crystal Display (LCD) screens use less energy and display a clearer picture than the Cathode Ray Tube (CRT) displays that preceded them. These new LCD screens now dominate the computer monitor market. From time to time, however, pixels can become stuck and a green line can display on the screen. Removing this line is sometimes possible without sending the screen to the manufacturer for expensive repair.

Locate the pixels that are stuck on the screen. Download a free screen repair software program, such as UD Pixel or JScreenFix. Run the software and allow it to find and attempt to repair the stuck pixels. Turn off the LCD monitor. Apply the damp cloth directly over the stuck pixels and use a gentle pressure to spread the liquid within the screen.

A line is appearing


I would try replacing the cable that connects the monitor to the PC first. It that doesn't clear the blue line, I would try if I could another monitor. It sounds like a row of pixels went out.

My monitor turns yellowish i can still work what is the problem. the monitor is a Acer V233H


The red "gun" of your CRT monitor is going bad. You will need to get a new monitor, and you should seriously consider an LCD flat screen. It will save you allot in electricity.

A CRT monitor is a very cool piece of technology inside... even though they are going obsolete with the advent of modern LCD displays.

In every CRT (Cathode Ray Tube) monitor, there is a trio of "Electron Guns"- they fire electrons at the front of the screen, hitting it with billions upon billions of electrons... the "bullets". Each gun is aimed at a set of colored targets, called "pixels"... one gun hits red ones, one for green, and one for blue. Combinations of these colors make up everything we can see.

When the red "gun" cannot fire enough electron "bullets" at the screen, the blue and green together make the picture appear yellowish.

If you want to learn more, look up "cathode ray tube" on wikipedia for starters!

A word of warning- the technology is very cool (I used to teach how CRT screens worked as part of my job teaching Missile fire control radar for the Navy), BUT:

THERE ARE VERY HIGH VOLTAGES INSIDE A CRT MONITOR THAT CAN KILL!!! DO NOT OPEN
THE CASE!!!!

Remember- the electron "guns" inside are shooting billions and billions of electrons at the front of the screen. They are being collected from the screen by a high voltage "supply". Most CRT's operate with anywhere from 15 to 45 THOUSAND VOLTS!

2 tiny black spots on screen, one looks like a check mark and one is a dot. Toshiba laptop satellite series. Dead pixels? How can they be fixed. Ran a program that is multi colored flashing lights to no...


Unfortunatly you do have dead pixels, but you cant fix them. Lots of lcd displays have them, some are more noticable than others, it dosent mean your lcd monitor is going to fail soon or anything like that, even brand new lcd monitors have dead pixels it is a comman anoying problem with them.

Green flashing pixels on all dark colours on my computer screen? they NEVER appear on light colours, just darker colours esp black, they move to fit whatever i have up, they tend to make straight lines or...


My suggestion would be to test your computer using a different monitor. You have to find out whether it is your monitor that is bad or your computer. If you use a different monitor and everything looks fine and you see no dots then you know the computer is fine and it's the monitor that is bad. But if the screen still show dots and lines even with different monitor then your computers video card has gone bad and needs replaced. I would not try to repair the monitor that can be dangerous.
Good Luck

Balck color turns into green


are the dots appearing in diagonal lines or randoml across the screen? This would suggest to me either a loose connection in your cable or the screen is faulty and will need replacing. Sorry for the bad news
