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 Cover all of sRGB color gamut
The monitor covers all of sRGB space and with some calibration is capable of representing the colors accurately.
Pro Good contrast
Pro Smooth surface
Among the least grainy matte surfaces available for UHD monitors.
Pro Low input lag
Complete input lag time (signal delay and pixel response time) is 6.85ms or under ½ of a frame.
Pro Can automatically shut down when you're away
The monitor has a proximity sensor that allows it to be automatically set to standby mode once you're away from the monitor for more than 40 seconds.
Pro Can auto-adjust brightness throughout the day
Can be set to automatically adjust brightness due to the built in ambient light sensor.
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 A maximum refresh rate of 60Hz can be a concern for some
A 60Hz monitor, while sufficient for most people in most cases, can still cause issues with fast-moving objects on screen. It's especially important with things like gaming where the ability to react to events happening on the screen quickly is important.
Con AHVA glow
AHVA glow is the light on the sides or corners of the screen that can reduce some of the peripheral detail.
Con Poor dynamic contrast implementation
Dynamic Contrast is an optional feature meant to increase or decrease the back-lighting depending on scene that is displayed in order to get higher dynamic range. Unfortunately, the implementation tends to slightly overshoot on highs regardless of the settings used.
Con Some color temperature uniformity issues
According to Spyder5Elite tests performed by PC Monitor, BL2711U has color temperature issues that can be seen with the naked. A DeltaE deviation of over 3 can be easily noticed and there are deviation of up to 3.8.
