Size class of the display as declared by the manufacturer. Often this is the rounded value of the actual size of the diagonal in inches. The percentage of the approximate area, taken by the active part of the screen, to the total front area. Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.

If the power is on, reboot the computer to see the initial screen (the login screen), which can be seen. If the initial screen (the login screen) appears, boot the computer in the applicable mode (the safe mode for Windows 7/8/10) and then change the frequency of the video card. Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.After calibration, you’ll be surprised about how AOC’s display expertise and high-quality panels ensure that most AOC monitors require only small amounts of calibration or no significant changes at all. However, if you need to execute colour-critical tasks, such as colour grading videos or editing images, you need to make sure that the monitor displays the colours correctly. Without a proper calibration, colours might be displayed in different hues on other displays. For instance, what you see as a true red in your digital creation might be displayed as more of a pink or orange on another person’s display – assuming their monitor shows accurate colours. In short, without calibrating, the colours displayed might not be true and therefore make colour-sensitive jobs unnecessarily complicated. Information about the brightness of the screen. It is measured in candela per square metre (cd/m²). Approximate height of the display. If the manufacturer does not provide such information, the height is calculated from the diagonal and the aspect ratio. Approximate diagonal size of the display. If the manufacturer does not provide such information, the diagonal is calculated from the width and height of the screen.

Try on a different computer. Windows only — if it works on a different computer, then the issue might be related to a USB chipset driver.You can see this message when the signal from the video card exceeds the maximum resolution and frequency that the monitor can handle properly. Information about the maximum horizontal viewing angle, within which the image on the screen is of acceptable quality. Windows only — try a different USB port. If it makes a difference, try updating the motherboard USB chipset driver. The monitor’s 16:9 aspect ratio accommodates widescreen content, allowing users to comfortably view movies, videos, and other multimedia. The viewable size measures 476.64 mm horizontally and 268.11 mm vertically, providing ample screen real estate for multitasking and productivity. Information of the number of pixels in a unit of length. With the decrease of the display size and the increase of its resolution, the pixel density increases.

The static contrast shows the ratio between the brightest and the darkest color, which the display can reproduce simultaneously, for example, within one and the same frame/scene. The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen. While colorimeters are good for transmissive media – emitted light (such as displays), spectrophotometers are also good for reflective media (such as paper). So if you want to make sure that what you see on the display is also what you will see when it’s printed out, than opting for a spectrophotometer might be a better idea. However, these come at a considerably higher price point than monitor-only colorimeters.With a display brightness of 200 cd/m², the AOC e2270Swn offers a clear and well-illuminated screen, facilitating visibility even in brightly lit environments. The pixel pitch of 0.248 x 0.248 mm ensures precise image reproduction, resulting in sharp and crisp visuals. The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC. Plug the device into a different USB port on your computer. If possible, don't use a USB hub or other similar device. If using a different USB port works, try updating the motherboard USB chipset driver.
