    iPad wallpapers need to be square to account for the tablet's screen orientation. If you choose a non-square image, you'll likely be left with a stretched image once you turn your screen.

  3. Defective pixel - Wikipedia

    en.wikipedia.org/wiki/Defective_pixel

    A stuck sub-pixel or stuck pixel is a pixel that is always "on". [2] This is usually caused by a transistor that is getting power all the time (VA/IPS) or not getting any power (TN) and is therefore continuously allowing light at that point to pass through to the RGB layer. Any given pixel will stay red, blue, or green and will not change when ...

    Three distinct types of defective pixels are described: Type 1 = a hot pixel (always on, being colour white) Type 2 = a dead pixel (always off, meaning black) Type 3 = a stuck pixel (one or more sub-pixels (red, blue or green) are always on or always off) The table below shows the maximum number of allowed defects (per type) per 1 million pixels.

  5. Image persistence - Wikipedia

    The cause of LCD image retention is different from phosphor aging as in CRTs, but the visual phenomenon is the same: uneven use of display pixels. Slight LCD image retention can be recovered. When severe image retention occurs, the liquid crystal molecules have been polarized and cannot rotate in the electric field, so they cannot be recovered.

    en.wikipedia.org/wiki/Screen_burn-in

    Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set.

    Retina display is a branded series of LCDs and OLED displays by Apple Inc. that have a higher pixel density than their traditional displays. [1] Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.

  8. Compression artifact - Wikipedia

    en.wikipedia.org/wiki/Compression_artifact

    Statistically, images have more low-frequency than high-frequency content, so it is the low-frequency content that remains after quantization, which results in blurry, low-resolution blocks. In the most extreme case only the DC-coefficient, that is the coefficient which represents the average color of a block, is retained, and the transform ...

  9. Display resolution standards - Wikipedia

    The next lower standard resolution (for widescreen) before it is WSXGA+, which is 1680 × 1050 pixels (1,764,000 pixels, or 30.61% fewer than WUXGA); the next higher resolution widescreen is an unnamed 2304 × 1440 resolution (supported by the above GDM-FW900 and A7217A) and then the more common WQXGA, which has 2560 × 1600 pixels (4,096,000 ...
