Question

i just bought a 19" envision flat panel/screen monitor from best buy. i used it for a couple of days, and now that i look i see like tiny green dot in the upper right hand corner. Should i go exchange this monitor or what is wrong. Thank you

Answer 1

What you are seeing is a know as a "dead" pixel. I would return the unit.

Answer 2

A dead pixel is a defective pixel that remains unlit on an LCD screen or a CCD or CMOS sensor in a digital camera. The term "dead pixel" is often applied to other defective pixels, but there are also separate terms. A permanently lit (white) pixel is called a hot pixel, and a pixel that stays on a solid color (red, green, or blue) is known as a stuck pixel.

A stuck pixel is a common pixel defect on LCD screens. A stuck pixel will be most visible against a black background, where it will appear red, green, blue, or any combination of the three (including white, although solid red, green, or blue, are the most common.) Each pixel on an LCD monitor is composed of three subpixels, one red, one green, and one blue, which produce the visible color of the pixel by their relative brightness. A stuck pixel results from a manufacturing defect which leaves one or more of these sub-pixels permanently turned on.

Fixing stuck pixels:

Unlike dead pixels, stuck pixels have been reported to disappear, and there are several popular methods purported to fix them, such as gently rubbing the screen (in an attempt to reseat the pixel), cycling the color value of the stuck pixel rapidly (in other words, flashing bright colors on the screen,) or simply tolerating the stuck pixel until it disappears (which can take anywhere from a day to years.) Stuck pixels are not guaranteed to be correctable, and can remain faulty for the life of the monitor.

Two methods have emerged, regarded to be 'folk wisdom', which can potentially repair a stuck pixel.


Applying pressure

1. Turn off your monitor.
2. Get yourself a damp cloth, so that you don't scratch your screen.
3. Apply pressure to the area where the stuck pixel is. Do not put pressure anywhere else, as this may make more stuck pixels.
4. While applying pressure, turn on the screen.
5. Remove pressure and the stuck pixel could be repaired.
6. Repeat if unsuccessful.


Cycling RGB colors

The second method involves cycling the main RGB colors on every pixel at a very rapid rate, often sustained for a long period of time. This has recently gained public interest after a video was created to help fix stuck pixels in the PlayStation Portable. However, there has been a more recent release by a coder named "crait" called "Pixer Fixer." This program has seen the most success for the problem on that system. A Java application using this concept has also been created for computers, and a homebrew application is available for the Nintendo Game Boy Advance.

A program using this method is available, UDPixel. However UDPixel flashes single pixels or a small region of pixels around the stuck pixel, and requires you to install .NET.

Answer 3

If it is a dead pixel, return it before within 14 days or you're stuck with having to contact the manufactuer through their warrenty process.
