Pros
Pro Designed for productivity
The 21:9 aspect ratio, 3440x1440 resolution adds horizontal space which helps with productivity. It allows for two apps to be open at the same time without turning them into a tall, skinny rectangle where you need to scroll back and forth (or, you could have 3 tall skinny windows open at once).
Pro Good adjustability
This monitor can be adjusted up or down 115cm, tilted up 21 degrees, down 5 degrees, or left/right 30 degrees. This lets you use the monitor comfortably in virtually every position.
Pro Light anti-glare coating
By using a light anti-glare (AG) coating, it prevents the screen from being too glossy, but without adding a grainy filter over the screen.
Pro Lots of ports
With an HDMI 2.0, MHL, DisplayPort, Mini DisplayPort, and a DisplayPort out port for easy Daisychaining, the U3415W has lots of connectivity options.
It also has 4 USB 3.0 ports for connecting a mouse, keyboard, and other peripherals to the monitor instead of the computer, allowing for easier access.
Pro Immersive experience
The curved, ultrawide display really helps make the experience immersive. Any games or videos that support the resolution wrap around you, immersing you into the experience even more - especially for racing games or flight simulators.
Pro Can charge a laptop
You can connect the S2718D to a USB-C compatible laptop and charge it.
Pro Works well in bright room
The Dell S2718D is an excellent option for those who are looking for a monitor for reasonably well-lit, office-like environment because of the excellent overall picture quality this monitor can achieve when placed in a bright room. The S2718D can display crisp and lifelike colors thanks to its IPS panel that offers fair peak brightness and the high resolution of 2540x1440 pixels.
Cons
Con Not all content is 21:9 compatible
Not all content will stretch well to fit the Ultrawide resolution. Games or videos that don't support the resolution will have vertical black bars on the left and right sides of the screen which take away the benefit of having an Ultrawide monitor.
Con Needs to be calibrated
You'll need to spend some time calibrating the S2718D because the monitor's out of the box color inaccuracy is very high - it measures at the dE of 5.46, which means that the color inaccuracies will appear perceivable by a human eye.
