Dell UltraSharp U3821DW review – Front

The Dell UltraSharp U3821DW is a 38-inch curved ultrawide monitor, which is why it looks rather wide. Looking at the front, you have rather minimal bezels with the Dell logo taking a small space on the bottom-center portion. It should still be relatively pleasing if you wish to do a multi-monitor setup unless you want one that is truly seamless.

Dell UltraSharp U3821DW review – Stand

The stand isn’t pre-installed so you will have to install it yourself. It’s a rather sturdy piece of metal consisting of two parts; the base plate and the metal bar. You don’t need any tools and it’s quite easy to assemble as there’s a ring on the base plate to keep the metal bar properly attached. It follows the same colour scheme as the monitor itself, which is gray. There’s enough space on the base plate to put a gamepad or two if you wish.

Dell UltraSharp U3821DW review – Rear

Switching over to the rear, you have the Dell logo taking centerstage, right above where the stand is to be installed. Below it, you have all the ports for the monitor, which we will get into at a later section. The power button and analog navigation is towards the bottom-left corner for easier access. It’s here that you can truly tell that the monitor is curved.

Overall, the Dell UltraSharp U3821DW monitor looks attractive but is definitely one that looks more suited for an office environment. That doesn’t mean you shouldn’t get one for home use of course. It has a clean look overall and I’m sure no one would complain about how it looks…aside from space if you’re lacking in that area.

Performance

The brightness of the display when measured at 100% brightness in Standard mode was 304.6cd/m2, and it seems that the monitor was running at 80% brightness by default, which measures in at 276cd/m2. There is no HDR here in case you’re wondering, and we will be conducting the test in Standard Mode.

Dell UltraSharp U3821DW review – Screen uniformity test

As this is an ultrawide monitor, I decided to run the screen uniformity test in a 3×5 grid format for better understanding. 6 out of 15 areas here passed the recommended tolerance whereas the remaining passed the nominal tolerance. The center area isn’t counted as that is the area used for reference. I certainly have no complaints here as through my own eyes, it does seem to be even on all areas.

Colour Accuracy

Standard Standard mode, calibration with DisplayCAL
Whitepoint 8009K 7887K
Average ΔE*00 0.31 0.35
Maximum ΔE*00 1.82 1.3

By default, the Dell UltraSharp U3821DW has good colour accuracy. After calibrating it using Spyder5 and DisplayCAL, the whitepoint was brought down slightly, with average Delta E figures being slightly worse but maximum Delta E figures seeing a notable improvement.

Gamut

Gamut Standard Standard mode, calibration with DisplayCAL
sRGB Coverage 99.6% 99.6%
Volume 131.2% 132.4%
Adobe RGB Coverage 82.7% 82.6%
Volume 90.4% 91.2%
DCI-P3 Coverage 90.8% 92.0%
Volume 93.0% 93.8%

For the gamut coverage and volume, it doesn’t seem to differ much before and after calibration. Overall with 99% sRGB, 83% Adobe RGB, and 92% DCI-P3, it does offer a relatively wide gamut coverage and should be suitable enough for most content creators out there unless you have a specific need for higher Adobe RGB or DCI-P3.

Dell UltraSharp U3821DW review

The Dell UltraSharp U3821DW is designed for productivity, and the ultrawide aspect ratio is to help you maximize on that. You don’t get those fancy features like HDR, G-SYNC, FreeSync, or anything like that. It’s straightforward and I enjoy using it but it ultimately depends on what you’re using it for as I won’t game on it. For starters, you get a robust offering of ports with some clearly designed to make your life easier.

Dell UltraSharp U3821DW review – Ports

You have a DisplayPort 1.4 and two HDMI ports, so you have more flexibility in planning out how you to want to use your display, especially in a multi-monitor setup. Then, you have an RJ45 port so you can get a stable LAN connection with ease and a USB-C port which not only supports DisplayPort 1.4, but also has Power Delivery up to 90W. This means that you can charge ultraportable laptops just by using the USB-C port.

Dell UltraSharp U3821DW review – Ports

Then you have an audio line-out and an array of USB ports with one that supports Battery Charging 1.2, giving 15W of power to charge your smartphone or tablet. This is particularly great because the number of plugs you need to use become lesser, therefore allowing you have less wires and clutter overall.

Dell UltraSharp U3821DW review – Buttons

Towards the bottom-left corner of the monitor’s rear, you have a power button and a navigational joystick. It’s simple and effective to navigate through the monitor’s OSD. Speaking of which…

The OSD itself is your standard Dell UI which is relatively straightforward. For the most part, you might need a bit of time to get used to it but once you know which setting belongs to what section, it will be a breeze to use it moving forward. There are also a number of profiles you can make use of depending on what you’re using the monitor for but I foresee most people sticking to Standard and ComfortView most of the time.

If you don’t have your own pair of speakers, headphones, or audio gear, I wouldn’t really recommend using the built-in speakers of the Dell UltraSharp U3821DW ultrawide monitor. The volume is decent but it lacks the dynamic range and crips detail that would give you an enjoyable listening experience. It sounds so flat that you would be better off getting a relatively affordable Bluetooth speaker for an overall better experience.

The Dell UltraSharp U3821DW does offer some versatility in how you want to use the monitor as it can tilt, swivel, and is height-adjustable. The metallic stand itself gives some space so you comfortably place your smartphone while it’s charging. If you want, you can swap it out for a VESA mount as it supports the standard 100 x 100 mm mounting brackets.

38″ Curved Dell UltraSharp U3821DW Review

With a robust selection of ports designed to simplify your life, good colour accuracy, ultrawide aspect ratio, sharp WQHD+ resolution, and a clean look that can easily fit at home or in a professional environment, the Dell UltraSharp U3821DW monitor is certainly an attractive display to own. It may be missing out on certain notable features like adaptive refresh rate and HDR but the performance speaks for itself.

At RM5,169, it’s certainly a pricey monitor to have but if you’re not looking to play games competitively and instead look at it from a productivity standpoint, it’s definitely worth a consideration. At the end of our Dell UltraSharp U3821DW review, I award this ultrawide monitor with our Silver Pokdeward.
