4.0 out of 5 stars If you have a Macbook Pro, look no further!
Reviewed in the United States on 31 March 2018
I purchased a top-of-the-line 15" MacBook Pro this year and struggled to use it for work since I heavily rely on dual monitors. This meant I had to run two USB-C to DisplayPort cables, a USB-C to USB-A hub, and another cable to power my MacBook. With this monitor, I run ONE Thunderbolt/USB-C cable to my MacBook and it works flawlessly. There are four USB-A ports on the monitor (2 in rear, two on the side), which I use to connect my wireless keyboard and mouse. Although these ports only run at USB 2.0 speeds when connected via USB-C, it doesn't bother me since I'm not using it for high speed data transfer.

Almost all other ultrawide monitors that have USB-C connectivity (besides the LG UltraFine) only supply a maximum of 60W of upstream power. Since a 15" MacBook Pro takes 85 watts to charge, you can end up relying on your battery to make up for the difference. The Dell U3818DW provides 100W of upstream power!

Now onto the display itself...

Picture Quality:
This thing is absolutely amazing when it comes to picture quality and text readability. I purchased an LG 34UC79G and hated using it for anything that required staring at text for any length of time. The Dell U3818DW runs at 3840 x 1600 (~111 PPI) and has roughly 40% more pixels than my old LG 34UC79G, which runs at 2560 x 1080 (~82 PPI). I can run Excel spreadsheets all day long on the Dell and my eyes don't feel fatigued, whereas the LG almost instantly gave me a headache. I occasionally play some Call of Duty and have to say it is pretty impressive on this monitor. Although it only has a 5ms response time and 60Hz refresh rate, it suits my needs for the small amount of gaming I use it for.

This thing is built like a tank! It arrived via UPS double-boxed with many "heavy" stickers slapped on it. The manufacturer's box is extremely thick with plenty of packaging to keep it safe during transport. The monitor alone weights about 27 lbs and feels very sturdy using the supplied stand. It can be VESA mounted if you want to keep the space underneath the monitor clear (which I may eventually do).

1 x DisplayPort 1.2 (HDCP 2.2)
2 x HDMI 2.0 (HDCP 2.2)
2 x USB 3.0 Upstream port
2 x USB 3.0 Downstream port (side)
2 x USB 3.0 Downstream port (bottom)
1 x USB Type-C (Alternate mode with DP1.2, Power Delivery, and USB2.0)

The built-in speakers are decent but are definitely not going to give you the low-range thump that you'd get with an external set of computer speakers.

Overall, this monitor is everything I have been looking for to complement my 2017 15" MacBook Pro with a single-cable solution. Yes, it is a bit pricey, but you will be very happy once you see it in person.

UPDATE: After using this monitor for a few weeks, I had to take off one star for the following reasons:

1) No display manager software for Mac. This means you’re limited to snapping two windows side-by-side. If you want more windows, you have to manually resize and arrange them.

2) Built-in monitor speakers cannot be controlled by the keyboard volume controls. Again, a limitation due to lack of Mac software/driver.

3) Changing inputs is a bit cumbersome. The auto detect can get annoying and manual input selection requires too many button presses.

Although these are minor complaints, it’s not a lot to ask for Mac drivers & software when it’s a $1,000+ computer monitor with USB-C support.
