    From the cheapest to the most expensive.. Important criteria for buying a suitable computer monitor

    0
    By umer shafi on June 2, 2021 The technology

    Usually one gets confused when wanting to buy a new computer monitor; Due to the large number of advertising promises and the diversity of models available in the electronics markets. A suitable monitor can be purchased by following some important criteria such as panel type, connection ports, and pixel density.

    And Andreas Roth – from the German technology portal Prad.de, which specializes in screens – explained, “Although many international companies provide screens at low cost, this is clearly at the expense of equipment, connection ports and practical functions.” In addition, the choice in the lower price category is limited to the 23-inch models, which are considered the minimum for a home office computer.

    And the German expert Andreas Roth added, “If the user is willing to pay more money to buy a new computer screen, he will get a 24-inch screen equipped with comfortable practical features and good technical equipment for office use.”

    Panel “TN”

    The user can only expect standard equipment with low cost screens. “Simple desktop screens usually include a Full HD TN panel,” explained Matthias Willendorf of Germany’s technology portal Inside-digital.de. The panel is the beating heart of computer screens, and it consists of millions of bright pixels that create the image.

    The acronym “TN” refers to the term “Twisted Nematic”, which means the arrangement of liquid crystals in the screen, and Matthias Willen dorf added, “TN panels are relatively simple and can be produced at low cost.” In addition, these screens offer a very fast response time and require very little electrical power; Therefore, almost all major monitors include TN panels.

    However, TN monitors have some drawbacks, including a limited viewing angle. “If the user looks diagonally down the image, the image cannot be checked immediately due to lack of contrast and distortion of color display,” Andreas Roth explained.

    IPS panel

    Screens with IPS panel provide a much better picture. Andreas Roth explained that the abbreviation “IPS” refers to the “In-Plane Switching” technology, in which crystals are arranged parallel one above the other, which leads to better color display and a greater viewing angle, Andreas added. “IPS monitors are a good choice for office use,” she said.

    VA technology

    There is a third technology that is being relied upon in the world of computer monitors, which is the “Vertical Alignment” technology, known as “VA”, which is a compromise between “TN” and “IPS” screens.

    Andreas Roth explained, “VA panels have the best contrast values, darker blacks and more stability in the viewing angle, even if they don’t come close to the level of IPS screen technology.”

    This is due to the vertical arrangement of the crystals, and the disadvantage of the VA screens is also its relatively high production cost, in addition to it consumes a large amount of electrical energy, and in terms of response speed, it is behind TN and IPS screens.

    Pixel density كثافة

    If a user wants to buy a large screen they have to take into account the pixel density, Matthias Willen dorf explained, “A large screen with a lower resolution provides a bad picture compared to a small screen of the same resolution.”

    The German expert advises to rely on a 27-inch IPS screen with a resolution of “2560 x 1440” pixels, and instead of using two screens, it may be better to use one screen in a widescreen format, but it will be at a significantly higher cost. NB.

    connection ports

    In addition, the user has to check that all necessary connection ports are available in the monitor to be purchased. Here, Andreas Roth advises, “Even in lower-priced models, the monitor should include a digital HDMI port with an additional port.”

    The deciding factor is the quality of the outputs on the computer graphics card, and Andreas Roth said, “The analog VGA port is still very important for the user used by computers or older devices.”

    USB hub

    Also useful equipment is that the computer monitor has a built-in USB hub. Wolfgang Boehler – from the specialized magazine “Chip” explained, “The user can find a “USB” hub in low-cost screens, but the “USB-C” port is rarely available in the category “USB-C”. Pricing for the basic models of screens.

    In addition, the user has to take into account some additional equipment such as built-in speakers, and Matthias Willen dorf said, “The speakers are often of poor quality, to the point that any external speaker is better.”

    Screen installation position

    Light sources play an important role when choosing the placement of the new screen, and Matthias Willendorf said, “It is better not to shine other light sources such as lamps or windows directly on the screen, because this increases the difficulty of reading or working on the screen.”

    In addition to the need to take into account the correct sitting height in front of computer screens, and it is preferable that the line of vision go down a little and that the distance between the eye and the screen is about 50 cm at least.
