This section provides information about troubleshooting steps that can help resolve the most common issues with the Dell P2423 monitor. Alternatively, to learn more about troubleshooting common issues on Dell monitors, see the Dell knowledge-base article Troubleshooting Display or Video Issues on a Dell Monitor or use our Monitor self-help Guide. Common Problem 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. Intel SME Study Disclaimer: Based on a 2018 survey of small business owners in five countries. Details here intel.com.au/smestudy The storage altitude shows the maximum possible altitude for secure storing of the display. Storing it above this limit may result in damaging the display. 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.

Designed with wellness in mind: ComfortView Plus an always-on, built-in low blue light screen reduces potentially harmful blue light emissions without compromising colour. Information about the number of pixels on the horizontal and vertical side of the screen. A higher resolution allows the display of a more detailed and of higher quality image.

Information about whether the stand can be dismounted. Usually, this is required for wall mounting.

Due to different video formats (aspect ratio) of DVDs and videos, the monitor may display in screen. 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. Accidental Damage-Additional Information: Accidental Damage Service excludes theft, loss, and damage due to fire, flood or other acts of nature, or intentional damage. Customer may be required to return damaged unit to Dell. Limit of 1 qualified incident per contract year. For more information, consumers visit Accidental Damage Service Contract (Consumer) or commercial customers visit Accidental Damage Service Contract (Commercial).

The operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. It sets a lower and an upper humidity level for safe operation and is measured in percentage. Information about the minimum amount of time, in which the pixels change from one color to another. Very often the manufacturer provides the response time for transition from grey-to-grey (G2G). Information about the maximum vertical viewing angle, within which the image on the screen is of acceptable quality.

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. IDC Whitepaper: “Optimizing Performance with Frequent Server Replacements for Enterprises” commissioned by Dell Technologies and Intel, March 2021. Results are based on interviews with 18 IT practitioners and decision makers at midsize and large enterprises and a web survey of 707 IT practitioners and decision makers at midsize and larger enterprises using Dell Technologies server solutions across 7 industries. See full whitepaper: https://www.delltechnologies.com/resources/en-us/asset/white-papers/products/servers/server-infrastructure-resiliency-enterprise-whitepaper.pdf The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10. Equipped with one USB Type B upstream port and 4 SuperSpeed USB 5 Gbps (USB 3.2 Gen1) Type-A downstream ports.

Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio. Dimensions, weight and color Information about the dimensions and the weight of the specific model with and without stand as well as the colors, in which it is offered to the market. Width The storage temperature shows the range from a minimum to a maximum temperature, within which storing of the display is considered to be safe. There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.

Wireless USB devices responding slowly or only working as the distance between itself and its receiver decreases. Conveniently connect to a variety of devices with extensive connectivity ports, including DisplayPort, HDMI, DVI, VGA and SuperSpeed USB 5Gbps. Change the color-setting mode in the Color Settings On-Screen Display Menu (OSD) to Graphics or Video, depending on the application. on Dell internal analysis using publicly available specs in August 2023 comparing maximum effective capacity for PowerStore 1200 and FlashArray //X20. Assumes average 4:1 data reduction for PowerStore, 5:1 for Pure Storage. Actual results vary. Dim or discolored video can be caused by the video cable, so try reseating the cable and swapping with a known good part.

Diagonal Size

Some USB devices like external portable hard drive require higher electric current; connect the device directly to the computer. When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade, it is always a good practice to isolate the monitor by running the Built-In Diagnostics. The operating altitude shows the maximum admissible altitude, at which the display will function flawlessly. Above this level it might not operate properly and/or might seize to function. A few permanently bright or dark pixels are considered normal by industry standards. The exact number of pixels that are allowed varies depending on the monitor. See the Dell Monitor Quality and Pixel Policy for more details.
