Relevant Background: "Computer display standards are a combination of aspect ratio, display size, display resolution, color depth, and refresh rate. They are associated with specific expansion cards, video connectors and monitors...The aspect ratio of a display device is the proportional relationship between the width and the height of the display. It is expressed as two numbers separated by a colon (x:y). Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10 and 16:9...As of 2016, most computer monitors use widescreen displays with an aspect ratio of 16:9,[1] although some portable PCs use narrower aspect ratios like 3:2 and 16:10[2] while some high-end desktop monitors have adopted ultrawide displays...On 2D displays, such as computer monitors and TVs, the display size (or viewable image size or VIS) is the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels...The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels...The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays...It is usually quoted as width × height, with the units in pixels: for example, 1024 × 768 means the width is 1024 pixels and the height is 768 pixels..Color depth or colour depth (see spelling differences), also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video framebuffer, or the number of bits used for each color component of a single pixel. For consumer video standards, the bit depth specifies the number of bits used for each color component.[1][2][3][4] When referring to a pixel, the concept can be defined as bits per pixel (bpp). When referring to a color component, the concept can be defined as bits per component, bits per channel, bits per color (all three abbreviated bpc), and also bits per pixel component, bits per color channel or bits per sample (bps)...Color depth is only one aspect of color representation, expressing the precision with which the amount of each primary can be expressed; the other aspect is how broad a range of colors can be expressed (the gamut). The definition of both color precision and gamut is accomplished with a color encoding specification which assigns a digital code value to a location in a color space....The refresh rate (or "vertical refresh rate", "vertical scan rate", terminology originating with the cathode ray tubes) is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every second by the device driving the display..." ("Computer Display Standard", https://en.wikipedia.org/wiki/Computer_display_standard).. To measure the size of the monitor or screen, one may measure the height and the width of the screen and then use the Pythagorean theorem to figure out the diagonal distance in inches. This distance in inches will be the size of the screen.

Relevant Background: "The performance of a monitor is measured by the following parameters:
  • Luminance is measured in candelas per square meter (cd/m2 also called a Nit).
  • Color depth is measured in bits per primary color or bits for all colors. Those with 10-bits or more are HDR monitors, which can display more shades of colors (approx. 1 billion shades) than traditional 8 bit monitors (approx. 16.6 million shades or colors), and can do so more precisely without having to resort to dithering, which would also reduce image sharpness. HDR monitors are required to be brighter than conventional montors while simultaneously showing deeper blacks (higher contrast ratios). The minimum brightness and contrast ratios are defined by the HDR standard the monitor adheres to.
  • Gamut is measured as coordinates in the CIE 1931 color space. The names sRGB or AdobeRGB are shorthand notations.
  • Aspect ratio is the ratio of the horizontal length to the vertical length. Monitors usually have the aspect ratio 4:3, 5:4, 16:10 or 16:9.
  • Viewable image size is usually measured diagonally, but the actual widths and heights are more informative since they are not affected by the aspect ratio in the same way. For CRTs, the viewable size is typically 1 in (25 mm) smaller than the tube itself.
  • Display resolution is the number of distinct pixels in each dimension that can be displayed. For a given display size, maximum resolution is limited by dot pitch or DPI.
  • Dot pitch is, in CRTs, the distance between sub-pixels of the same color in millimeters. In LCDs it is instead measured in pixels per inch or dots per inch (PPI or DPI), In general, the smaller the dot pitch, or the higher the PPI or DPI, the sharper the picture will appear.
  • Refresh rate is (in CRTs) the number of times in a second that the display is illuminated. (The number of times a second a raster scan is completed) In LCDs it is the number of times the image can be changed per second. Measured in Hertz (Hz). Maximum refresh rate is limited by response time. Determines the maximum number of frames per second (FPS) a monitor is capable of showing.
  • Response time is the time a pixel in a monitor takes to go from active (white) to inactive (black) and back to active (white) again, measured in milliseconds. Lower numbers mean faster transitions and therefore fewer visible image artifacts such as ghosting.
  • Display lag is the time (measured in miliseconds (ms) it takes for a monitor to display an image after receiving it.
  • Contrast ratio is the ratio of the luminosity of the brightest color (white) to that of the darkest color (black) that the monitor is capable of producing simultaneously. For example, a ratio of 20,000:1 means that its brightest white can be 20,000 times brighter than its darkest black. Dynamic contrast ratio is measured with the LCD backlight turned off.
  • Power consumption is measured in watts.
  • Delta-E: Color accuracy is measured in delta-E; the lower the delta-E, the more accurate the color representation. A delta-E of below 1 is imperceptible to the human eye. Delta-Es of 2 to 4 are considered good and require a sensitive eye to spot the difference.
  • Viewing angle is the maximum angle at which images on the monitor can be viewed, without excessive degradation to the image. It is measured in degrees horizontally and vertically...

  • Universal features

    Power saving

    Most modern monitors will switch to a power-saving mode if no video-input signal is received. This allows modern operating systems to turn off a monitor after a specified period of inactivity. This also extends the monitor's service life. Some monitors will also switch themselves off after a time period on standby.

    Most modern laptops provide a method of screen dimming after periods of inactivity or when the battery is in use. This extends battery life and reduces wear.

    Integrated accessories

    Many monitors have other accessories (or connections for them) integrated. This places standard ports within easy reach and eliminates the need for another separate hub, camera, microphone, or set of speakers. These monitors have advanced microprocessors which contain codec information, Windows Interface drivers and other small software which help in proper functioning of these functions.

    Touch screen.....

    These monitors use touching of the screen as an input method. Items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.

    Consumer features....

    Glossy screen...

    Some displays, especially newer LCD monitors, replace the traditional anti-glare matte finish with a glossy one. This increases color saturation and sharpness but reflections from lights and windows are very visible. Anti-reflective coatings are sometimes applied to help reduce reflections, although this only mitigates the effect...Newer monitors are able to display a different image for each eye, often with the help of special glasses, giving the perception of depth. An autostereoscopic screen can generate 3D images without headgear...

.....Ultrawide screens.....Monitors that feature an aspect ratio of 21:9 or 32:9 as opposed to the more common 16:9. 32:9 monitors are marketed as super ultra wide monitors....

Windows Disk Partition Too l *** Q: How does one access disk partition tool using Administrative Tools under Control Panel? How does one check for different disk partitions?  A: As shown in the video **** Applications: Create disk partition for Windows , Memory Dump , Data Corruption , Data Back up & Recovery ***** Relevant Background: " Disk partitioning  or  disk slicing [1]  is the creation of one or more regions on  secondary storage , so that each region can be managed separately. [2]  These regions are called partitions. It is typically the first step of preparing a newly installed disk, before any  file system  is created. The disk stores the information about the partitions' locations and sizes in an area known as the  partition table  that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk.  Sy...
