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.
