How do I fix dead ( not stuck) Pixels on my acer laptop? It appears like a smll hole in screen


You can't fix dead pixels, the transistor is faulty. This is indicated by black spots.

Stuck pixels remain a solid color other than white. This cane sometimes be fixed using software that flashes solid colors on the screen. Hot pixels remain solid white. this can be fixed in the same manner.

White spot on screen


Sounds like you are describing stuck/dead pixel.

There is no fix, it is a Pixel gone out in display panel, good chance it is just stuck and will right itself but sadly sometimes they dont and the only fix is to replace the entire display panel
Manufactures warrant such defects different depending on amount of dead pixels on screen is considered faulty, ie 3 pixels grouped or 5 separate ones .

Why the white or black spot on LCD Display


Dead and Stuck Pixels <br /> Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel. <br /> A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background. <br /> A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed. <br /> Hope this helps, if so do rate the Tip

Tiny black spot lcd


Erika, Do you mean you have a black spot on the LCD of your camera?
We call that a dead pixel. Can be black and can be white. Most LCD's sooner or later have a one or more dead pixel(s). As long as they are not in the centre of the screen you won't notice them. Even dead pixels on the camera sensor can happen. These you won't see at all, because the software does calculate what that pixel would look like in that specific shot. And the software will place a correct colour on that spot.
Try to live with the dead pixel(s). you won't see them on the actual pictures. Not on the computer to tablet and not on a print.

Samsung DLP white spots


Are the spots fixed or do they move with the image? Verify that all venting is clean of dust. If the spots are fixed and upon close examination are a square shape, The device is overheating of failing. If the spots are moving with image it's a front end problem, and can be overheating as well.

Bubble-like spots on lcd


Your Licquid Crystal Display appears to have gone bad... much like a dead pixel in a TV, you get a dead spot on the display of your lcd that looks like a bubbe.

You need to have the screen replaced or you will have to live with the bubbles. If the PC is still under warranty I'd send it in for repair. You may be able to pick up an inexpensive replacement on eBay, but make sure you are careful if you replace the screen yourself.
