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+. Use the buttons at the bottom of the monitor to access the On-Screen Display (OSD) menu of the monitor. To access the On-Screen Display (OSD) menu, press Button 5 ( Figure 1) at the bottom of the monitor.

When mounted on the wall or on a monitor arm, the set up must comply to the recommended panel orientation and working angle. 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. To navigate the On-Screen Display (OSD) menu, use the buttons on the monitor. The monitor control buttons are usually on the right side , either on the side, front or bottom of the monitor. To access the On-Screen Display (OSD) menu, press Button 5 on the monitor. Solid white light indicates the monitor is On and fully functional. Blinking white light indicates the power save modeWindows Display Settings and the resolution settings on the laptop's video or graphics utility may not be compatible Note: This is applicable for a monitor with a stand.

Additional monitor information like the model number, firmware version and Service Tag can be accessed from the monitor's OSD (On Screen Display). Press Button 3 or Button 4 to highlight Factory Reset option in the menu and press Button 5 to select. The U4919DW's resolution is much higher—5,120 by 1,440 pixels, as opposed to 3,840 by 1,080 for the Samsung. This means that the U4919DW has a higher pixel density, 106 pixels per inch (ppi), compared with 81ppi for the Samsung. Too low a pixel density can affect image sharpness. Text and photos rendered by the CHG90 were not particularly sharp, but the U4919DW handled both well. The native resolution of 5,120 by 1,440 is functionally equivalent to two 1440p (2,560 by 1,440) displays, side by side in one enclosure.

A potential deal-breaker is the U4919DW's hefty price. Even discounted off of MSRP at this writing, it was costly. You could opt for the Samsung CHG90 and still spend hundreds less. The tradeoff for the savings is the lower native resolution and correspondingly lower pixel density of that gaming-centric monitor, which could adversely affect image quality. True to its UltraSharp moniker, the U4919DW rendered sharper images in our testing than we saw with the CHG90. Dell U4919DW monitor uses a curved IPS panel, the corners of the screen may appear slight yellowish or pinkish, especially when viewing in dark room. This is normal IPS panel behavior and typically does not affect the overall viewing performance.Display mode changes from "Second screen only" to "Extended mode" after opening and closing the laptop LCD
