I have (suddenly) a single dotted black line about a quarter wasy down my screen on laptop. Can I get rid of it?


Hello,

First, you need to verify if the dot is cause by faulty graphics chip/card or LCD/LED. To do this use external monitor, if you cant see dot on your external monitor then you have faulty LCD/LED if you see dot like in your laptop the you have graphics chip/card problem.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

When I connect the lcd to my laptop, the lad shows


hi atuire,

try hooking up the lcd screen toanother computer and if it shows the same double screen again then there is aomething wrong with your lcd monitor,
you may want to use another monitor with your laptop to ensure the problem is not on the laptop's side.

if issue stays same with another monitor, then just right-click onto desktop background, goto properties and have a look whether you have enabled the shared monitor feature
(meaning that u can use two screens with just one graphics card parallel, to work on a 'wider' range of sight.
Therefore your machine's graphics card sually must be equipped with both: a standard vga out and a HDMI-out as well.)

if your machine ddoes not have these capabilities but still the monitor sharing is turned on from the software side, this might cause the problem. To disable simply change the graphics card's
propertiers as descried above.

Good luck

Sony a100 distortion dots - Im getting several


If these are single pixels on the LCD screen, they are normal. From pg. 8 of the user's guide:

"The LCD monitor is manufactured using extremely high-precision technology so over 99.99% of the pixels are operational for effective use. However, there may be some tiny black points and/or bright points (white, red, blue or green in color) that constantly appear on the LCD monitor. These points are normal in the manufacturing process and do not affect the images in any way. "

This may also be helpful.

"images may trail across the LCD monitor in a cold location. This is not a malfunction. When turning on the camera in a cold location, the LCD monitor may become temporarily dark. "

HP 1740 LCD Monitor, showing 4 blue dots on screen


Does the rest of the picture come in okay? Just 4 small dots? Those are probably dead pixels. I believe you have to have 5 (in most cases) to claim it as defective. Some people have had success tapping on them (be gentle) otherwise, you can send it into a repair company.
