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.

Is it true that when one pixel goes out, others are soon to follow?


No, that's not true at all. Each pixel is its only little device - one pixel does not effect another. The pixels work together to make a picture, but are all controlled separately. If your pixel is "stuck" and not dead, then you may be able to fix it! A stuck pixel is red, blue, green or white, while a dead pixel will show up as black. Sometimes a stuck pixel can be fixed by covering a pencil eraser with a cloth and pushing down on the pixel gently while the TV is on. So, in summary - no, one bad pixel doesn't mean any other pixels are bad. Hope that helps, Alex

Hello

Make sure TV is on the correct channel or input. Check the cables for correct routing from TV to any other devices. Check cables to ensure they are tight and secure.

An analog signal converted to high defintion resolution will cause lines, blurriness or fuzziness in the picture. Change the resolution to a lower or native setting using the media device (cable box, DVD,). This may be an issue that requires a service call to cable provider.

A problem on one channel may just be a error on that channel. If using an antenna, it might need to be adjusted in order to ensure good signal strength. For digtal channels, go into TV Menu. Check the DTV signal. Weak signal can cause picture distortion.

If another device is being used such as a cable box, DVD player or VCR switch between devices and test picture. Check routing of cables that are used to control the image. This should be a series of red, white and yellow cables.

If a VCR with a cable box, make sure the VCR and TV are set to the correct channels for video signal to pass through. If problem is still occuring, try another set of cables. bad cables can cause picture distortion.

Bad cables can cause picture distortion as well. Try another set of cables. If picture is better than when using the cables replaced, this was the issue. If cables are not an issue TV may require service.

When scanning dots show up in a vertical pattern


Printer DPI and PPI Ratings, General Dots per inch stands for the maximum number of tiny spots of ink that the printer can place in a straight line where the spots are theoretically small enough (i.e. ignoring spreading or smearing effects of ink on paper) that if placed in every other such dot position leaving white space between them, the spots can be individually distinguished. Pixels per inch stands for the maximum number of unique positions in a straight line that the printer can place an ink spot under control from the outside world, namely from a computer connected to the printer. Lines per inch stands for how close thin parallel lines can be printed and still be distinguished in the finished printout. The spaces between the lines count as "lines". Pixels per inch and dots per inch originally referred to the same thing. The printer mechanism was under the direct control of the computer and was physically positioned and placed dots as directed by the computer. Back then, most printer mechanisms were limited to placing dots only in positions suggested by a grid of dots X per inch horizontally and Y per inch vertically, for example 100x100 dpi Nowadays, many printers put dots "wherever they want" as opposed to in positions suggestive of a horizontal/vertical grid. Still there is a minimum dot size and a minimum dot spacing. A picture file (image file) represents pixels in a uniform horizontal/vertical grid pattern. And the printer needs to make a finished picture of the size, say 5x7 inches, that the user chose regardless of the number of pixels in the picture file. To simplify the process of relating the pixel count in the picture file to the possibly non-uniformly spaced dots on the paper, the printer or its supporting software may generate a temporary intermediate picture file with a set number of pixels per inch. The printer may have, internally, several choices of ratio of pixels to dots and the published rating can be the largest ratio except that the published rating may not exceed the dpi rating. Therefore there might be three "per inch" values involved at a given time, the pixels of the original picture file, the pixels per inch that the printer works with, and the dots per inch of the printer mechanism. Pixels per inch is usually not mentioned with printers. All printers come with their own software (including parts called drivers) to install on your computer. Usually the software does not let you exercise control over individual dots using your picture file. Rather the printer takes your picture file or data file and uses its own built in logic to lay down the dots and create the printed output. We are led to believe that a printer's ppi is usually a fraction such as a half or a third of its dpi rating. When a temporary picture file is created, there are at least two levels of software in use. High level software (which may run in your computer) takes your picture file and creates the temporary file. Low level software runs in the printer, takes the temporary file and controls the dot size and dot placement on the paper. Sometimes a printer is advertised using a phrase such as "300 dpi 1200 dpi quality". This means that the printer has some way of making dark edges on a light background appear smoother than the first number would otherwise suggest. A printer with 300 dpi 1200 dpi quality definitely cannot resolve alternating dark and light pixels less than 1/300'th inch each. But curved and diagonal lines and color boundaries should not have jagged edges suggesting individual dots rigidly positioned on a grid with a 1/300'th inch pitch.

I have an LCD TV. All of a sudden the picture colour has gone wierd. The best way to describe it is that it is similar to either a colour negative or one of those scientific 'false colour' images. This...


TFTs can produce a wide array of colors, but it takes an enormous number of transistors to make up a display, and a problem with any one of them creates a defective pixel on the screen. Typically this shows up as a bright spot on a dark background, caused by a damaged TFT failing to turn off a pixel. Most active matrix displays contain a few bad pixels, but a few bad pixels are not going to have much of an impact on the overall picture.
The properties of liquid crystal material can create problems with viewing angle effects, causing the image to darken, disappear, or reverse the dark and light tones when the viewer is not directly in front of the display (kind of like looking at the negative of a photo). The light bulbs make LCDs heavier than the plasma TVs (though they are still lightweights compared to CRT televisions.
Benefits of LCD TVs include a picture that can't burn in and doesn't deteriorate over time. Because of their flat-panel nature, placement options are plentiful, optimizing the cool factor over standard TVs

Try uninstalling and reinstalling the video drivers. If this doesn't work, it's likely that the LCD control board or cable is damaged.
