For a monitor the size of an average TV from the American company Dell, there may not be room on every desk — stretching nearly a meter wide, the 37.5-inch "giant" requires ample space for installation.
Giant
The support for the truly enormous IPS panel with a resolution of 3840x1600 pixels and an unusual aspect ratio of 24:10 is a massive "stand" with a round hole for cable management. Instead of desktop installation, the monitor can be wall-mounted using a 100x100 mm VESA mount.
Color Gamut
The factory calibration of the monitor covers 99% of the sRGB color space. In reality, this figure turns to 93-94%, which is still quite good. Although the screen refresh rate is limited to the standard 60 Hz, this is often more than enough when using the model in "work-games-entertainment" mode.
Two-in-One
The software modes "Picture-by-Picture" and "Picture-in-Picture" allow simultaneous display on the monitor screen from two different sources. Connecting external devices is done through a wide array of interfaces, including a USB Type-C port for audio and video transmission alongside laptop charging (with a power consumption level not exceeding 100 W).
Strong Player
The monitor also earns a solid "five" for its high-quality materials and assembly. Direct competitors to the model can be counted on one hand (for example, LG 38UC99), so in its niche, the Dell U3818DW is a very strong player that confidently outpaces its closest contenders.
