Just to confirm: It’s OK that I have the power cord attached (laptop to wall) AND have the D6000 cord attached. That “double” source of power isn’t harmful, right? It sounds like you’re saying that the D6000 is too weak and therefore using both is not only acceptable but necessary, right? Below is a chromaticity chart of the sRGB color space, 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 my measurements, mostly lie a bit outside the triangle and are fairly evenly spaced.

Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. This model offers a pixel density of around 117PPI which isn’t close to 4K monitors, but sharp enough to produce clear and detailed images. Small objects like text can become less legible for some users, but as long as your eyesight is healthy you won’t have any problems. Gaming and videos look great since the pixels aren’t noticeable on this device when it viewed at a normal distance. The Dell U2520D also has a wide array of connectivity options that you won’t find on its competitors or gaming variants in the market. The monitor uses its DisplayPort 1.4 and HDMI 2.0 slot as primary inputs, but it can also utilize its 90-watt USB-C port for single cable operation with laptops like the MacBook Pro. You will also find a second DP 1.4 slot for output which supports daisy-chaining for a seamless dual monitor setup. The Dell U2520D is a well-designed and equipped monitor for a variety of roles in business and home use cases. The monitor’s connectivity layout is easily one of the best in the market now, while the functional features such as the ergonomic stand make it a good buy if you want something that’s very user-friendly. The IPS panel also provides great image quality which does not need calibration to get a balanced or correct image output.Use the USB-C cable that came with the U2520D to connect the USB-C input on the U2520D to the USB-C port on the XPS. At that point you'll have both video and USB data (to enable the USB ports built into the display) running over that single cable, rather than just video as you would have if you got a USB-C to DP cable. You'll also have 90W of power coming from the display, which is better than the 65W available from the D6000 but still not ideal for your XPS 15. Massive and sincere thanks for all that info. Very helpful. Point taken about providing all relevant tech info up front. Will try to do so in the future. Dell claims color-gamut coverage of 99 percent of the sRGB color space, the standard color space used on the web and in many other applications, out of the box. The U2520D surpassed that, covering 99.9 percent of sRGB.

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 I would say that the D6000 is fine as a typical everyday productivity solution, but games would definitely be a problem, because on top of the loss of the NVIDIA GPU, you'll have the additional performance and image quality penalties of DisplayLink's compression that exist even with systems that only have a single GPU. You might even find that full screen video is a bit of an issue in terms of motion and/or compression artifacts, though this might depend on the resolution of your display and what else is going on with your system when trying to watch it. The buttons make it easy to navigate through the OSD. You can change color space, input source, brightness, contrast, and a host of other parameters. Note that if you daisy-chain a second monitor, you will first want to enable the MST setting in the Display menu. It Nails the sRGB Color Space Rated luminance and contrast ratio are 350 nits (candelas per meter squared) and 1,000:1, respectively. In Standard mode, it turned in 280 nits, a bit shy of its Dell rating but still bright enough for its intended tasks, and an 1,141:1 contrast ratio, somewhat better than its rating. (See how we test monitors.) The U2520D is a good choice for a multi-monitor array. You can use the DisplayPort-out connection to daisy-chain a second monitor, which will be automatically detected and configured using Dell Express Daisy Chaining, which I first tested in the Editors’ Choice Dell 27 USB-C Monitor (P2720DC) mentioned up top.

The stand on the Dell U2520D is fully flexible, so its easier to arrange your desktop in a suitable way that is both comfortable and functional. It also comes in handy if you want to set up multiple displays, especially since this model supports daisy-chaining. You can opt for a VESA mount with a 100 x 100 bolt pattern, but we only think it’s necessary in extreme or special circumstances. The Dell U2520D doesn’t have FreeSync, so naturally, it also won’t work with Nvidia’s G-Sync Compatible mode. You don’t get protection from tearing with this model, so optimizing your graphics settings to stabilize the framerate is necessary. Input lag sits at 10ms, so there will be no delays between your inputs and the display. Thoughts on the Dell U2520D Dell also reduced the footprint of its 2020 offerings without sacrificing its stability once propped up on a desk. The base on this model only needs 7.28 inches of depth, and it won’t consume more horizontal space than your average office display. The chassis itself is also noticeably slimmer, giving you that minimalistic and modern vibe that not a lot can offer.

Display and Performance

But if you ever wanted to ditch the D6000 -- which you may want to -- then since the XPS 15 supports video output and system charging on all of its USB-C ports, then no you would not need a separate DisplayPort cable for video. Again, USB-C is capable of carrying power, video, and USB data all simultaneously and all over a single cable, as long as your laptop's USB-C port supports all of those things, which is the case here. When I said "send video to your display", I didn't mean movies. I just meant that you could send a video signal to your display that will allow it to display an image, and therefore would not need DisplayPort when using a USB-C to USB-C cable. If you’re looking for a compact but elite productivity monitor that displays color well, the U2520D is well worth your consideration. It costs less than the Lenovo P27u-10, and it features much better OSD navigation. It has a similar feature set but a smaller screen than the Editors’ Choice Dell 27 USB-C Monitor (P2720DC). They both have very good color accuracy, a full range of ergonomic features, and a generous port selection, plus both support automatic daisy chaining of a second monitor. Hard drive retention: Hard drive retention is not available on models with a soldered hard drive, including XPS 9315 2in1, Chromebooks or Venue tablets, except the Venue 11 Pro. The U2520D has a VESA DisplayHDR 400 rating, the most basic level of VESA’s HDR scale. It has several HDR settings: DisplayHDR, Movie HDR, and Game HDR. It’s worth experimenting with them to see which you find the most pleasing. The U2520D handled both still and moving images well. Colors looked reasonably true and rich, and both contrast and dynamic range were spot-on. Our sample videos looked sharp and fluid, and showed a modest improvement in contrast with the Movie HDR setting enabled. A Whiz at Image Handling

Responsiveness isn’t a strength of the Dell U2520D since it was not designed for gaming and its refresh rate is limited. Swiping or panning the screen too fast will reveal some trails in contrasting transitions, making this variant unsuited for fast-paced gaming. Casual titles won’t have an issue, but there are cheaper and better monitors if you want a display that’s dedicated to entertainment. Navigation through the U2520D’s onscreen display (OSD) is easy and intuitive. It is controlled by four small, physical buttons next to the power button on the right side of the monitor’s bottom bezel. When you press any of them, all four buttons become labeled by illuminated icons above them. Once you enter the menu system, they are identified by up, down, and right arrows, plus close. Build quality is fantastic like most Dell monitors, so you have no reason to doubt the Dell U2520D’s reliability and durability. The plastics feel reinforced and sturdy, while the seams and edges are straight and smooth. The device doesn’t exhibit any kind of wobbling so you won’t see annoying vibrations on the screen if you are a heavy typer. You can improve the color dE to an average of only 1.13 if you have a colorimeter, but we think it is unnecessary unless you are into editing and content creation. The extra cost of the gadget plus the high-side price of the Dell U2520D is too much, and the total can get you a higher-tiered model that will perform better in this regard. The only setting you need to touch right away is brightness since you need to find a perfect level that is comfortable for your eyes during extended use.
