  • Size

    The diagonal is the number used to describe the size of the screen. The most popular sizes are 24 and 27 inch screens.

  • Response Time (GTG)

    The time it takes for a pixel to change from one shade of gray to the next. A low response time provides faster response to our actions (input lag) and a cleaner image (less ghosting) which are important in gaming. Response times below 5ms are considered acceptable, but for gaming, monitors with 1ms are recommended.

  • Connection Type

    DisplayPort

    Modern way of digital transfer of image, sound and data, compatible with HDMI and DVI cables through an adapter.

    HDMI

    The type of connection used by popular gaming consoles such as Playstation 4/5, Xbox X/S, Nintendo Switch, etc. (Support for HDMI 2.1 is required for high fps and 4K resolutions.)

  • Refresh Rate

    Refers to how many times the screen image is refreshed per second. Screens with a high refresh rate offer a competitive advantage as their image is clearer (less motion blur).

    2. Typically, for office applications and simple gaming, 60-75Hz is common. In recent years, screens with 120, 144, and even 240Hz have emerged, mainly aimed at competitive gaming.

    240

    It offers a competitive advantage compared to screens with lower refresh rates as the image is clearer (less motion blur).

    If the computer does not exceed 165fps (frames per second) in games, there is no difference with a 165Hz screen.
