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 Excellent general purpose monitor
Impressive amount of on-screen real estate, excellent picture quality, exceptional connectivity, and great color accuracy puts the LG 38UC99-W above nearly all competitors in the market.

Pro Excellent for watching movies
Acing the near-cinematic aspect ratio of 21:9, the LG 38UC99-W is an excellent companion to watch movies because you won't see the black bars at the top and bottom of the screen when watching most movies.
Pro Has a pair of good speakers
The LG 38UC99-W features a built-in 20 Watt stereo speaker system which sounds fairly well compared to the 4-10 W speakers the competitors at this price point offer.
Pro Exceptional connectivity
This monitor beats most of its premium competitors in terms of connectivity because it features a USB-C downstream port which has multiple parallel functions. First, you can use it to access the monitor's onboard USB hub. Second, it can be used for charging a USB type C compliant laptop. Finally, you can use it to receive video and audio signal from a computer.
Additionally, the LG 38UC99-W has two HDMI ports, a DisplayPort, and an inbuilt Bluetooth module.
Pro Supports dual linkup
You can connect this monitor to two computers so that each machine use half of the on-screen area. This might come in handy for those who frequently use a stationary desktop computer and a laptop.
Pro Great picture quality
Only the best monitors can match the LG 38UC99-W's contrast ratio, peak brightness, gamma, and color accuracy, as the monitor features one of the finest IPS panels in the industry.
The LG 38UC99-W displays beautiful pictures, with deep and rich blacks, vibrant and accurate colors, and good-looking intermediate tones. Despite the fact that the monitor's native contrast ratio is only 1000:1, the dark scenes look deep and intense as the backlight of the 38UC99-W can drop below the brightness level of 0.15 nits, which only the best monitors can do. Colors pop and look vivid, as the 38UC99-W can sustain its brightness above the 300 nits mark. The mid-tones look lifelike thanks to the monitor's near perfect gamma value, which is only 1.3% off from the ideal value.
Moreover, the monitor's color inaccuracies can't be seen by the human eye because it only has an average color error dE of 2.12.
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 Very expensive
For the same price as this monitor, you can buy three decent 27-inch ultrawide monitors.
Con Bluetooth indicator is inconvenient
The monitor's Bluetooth indicator occupies the on-screen workspace. Unfortunately, there is no way to remove the indicator while using the Bluetooth speaker option.
Con Has an external power brick
The external power supply unit of the LG 38UC99-W might cause inconvenience especially if you want to mount this monitor on a wall since the PSU is quite bulky.
Con Wobbly
The stand isn't rigid, so you might observe some minor wobbling if your work desk is flimsy,
Con OSD is quite messy
The on-screen-display of the LG 38UC99-W does not have any programmable shortcut keys and is quite hard to navigate.
For example, to enable or disable the motion blur reduction feature, you’ll need to press more than 15 keys because the menu goes very deep.
Con Unsuitable for gaming
Gaming just doesn't feel responsive because of the monitor's massive input lag.
