Ranked in these QuestionsQuestion Ranking
Pros
Pro Good image quality
Vibrant, sharp & good overall color responsiveness with 1.073 billion colors and a 5ms response time.
Pro Full swivel stand
You can turn it fully to a horizontal or vertical position.
Pro Good selection of connectors
Dell P2815Q has HDMI 1.4, Thunderbolt, 2 DisplayPorts (1 in, 1 out) and 4 USB 3.0 ports. HDMI 1.4 & Thunderbolt are capable of 4K @ 30Hz.
Pro VESA mount
So you can mount it to a desk stand or a wall.
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.
Cons
Con Bad viewing angles
Since it's a TN monitor, it has worse viewing angles compared to IPS displays.
Con Bad refresh rate
At 3840 x 2160 it's max 30Hz and at 1920 x 1080 it's max 60Hz.
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.
