Most users will buy this monitor for general use, and for that, it excels. We ran Windows 10 at 100 percent font scaling, which provided the best possible quality when rendering small icons and fonts. Text of all sizes looked smooth without visible jaggies or anti-aliasing. The connectors on the U4919DW comprise two HDMI 2.0 ports, two upstream and five downstream USB ports, one DisplayPort 1.4 port, and a USB Type-C port. You can use the last one to charge or power devices while the USB-C can also transfer data over the cable. You won’t need to do much in the OSD for most applications. The Standard picture mode provides good color accuracy in the sRGB gamut along with a 6500K white point and 2.2 gamma. There are five additional modes for games or movies. One preset allows you to change the color temp by Kelvin value. Our favorite, however, is "Custom Color". There you can benefit from RGB gain and bias controls, along with hue and saturation sliders for all six colors. Surprisingly, there are no gamma options. 2.2 is the one and only supported spec. Caution: Dell U4919DW setup must comply to the recommended panel orientation and working angle only. Setting up the monitor in an orientation that is not recommended may damage the monitor and / or cause a safety hazard. Use a USB-extender cable to position the wireless USB receiver as far away as possible from the USB 3.0 port.
When monitor is connect to the PC via HDMI, the video or graphics card (GPU) controls the YCbCr setting When mounted on the wall or on a monitor arm, the set up must comply to the recommended panel orientation and working angle. Above is a color accuracy or chromaticity chart, which was generated when testing in standard mode. The area within the triangle represents all the colors that can be made by mixing the primary colors red, green, and blue. The circles, representing our measurements, lie just outside the triangle and are fairly evenly spaced, indicating a slightly expanded color gamut.
The next button over lets you control brightness and contrast, with sliders for each. The fourth lets you choose an input source (the two HDMI ports, DisplayPort, USB-C, or Auto-Select). The fifth offers a menu to access all the settings listed here plus some additional ones, while the final button lets you cancel a command.
When you close and then reopen the lid on a laptop, the Connecting and Configuring Displays (CCD) feature in Windows automatically reverts the display mode to the last active selection. This behaviour is by design in Microsoft Windows. The Picture-By-Picture (PBP) mode is especially useful given the U4919DW’s width. You can have two full resolution QHD images side-by-side from two different sources. It’s also possible to adjust contrast independently between the two sources, very nice.The monitor sits on a stand with a sturdy base that takes up a substantial (10-by-14-inch) footprint. The stand has some ergonomic chops, supporting 3.5 inches of height adjustment, and 26 degrees in tilt adjustment. Also, it's set on a ring that can rotate up to 170 degrees in either direction. Multi-tasking takes on a whole new meaning with a screen this wide. The curve put everything easily in view without distorting graphics or square objects. We could sit anywhere in front of the U4919DW and see the image clearly. Viewing angles were excellent, and the monitor can easily be shared by two people. Color was vivid and natural with an accurate white point that made reading white screens easy on the eyes. We also enjoyed using the PBP feature to show two sources at once. For versatility, this Dell gets an A+. Disable the YCbCr setting from the video or graphics card (GPU) utility like Intel HD Graphics Control Panel
