Ranked in these QuestionsQuestion Ranking
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 Convenient controls
You can access the monitor's setting using your keyboard and a mouse because the monitor supports LG's On Screen Control software.
Moreover, the software features the Screen Split function which lets you organize the real estate of your monitor according to your needs.
Pro Not power-hungry
On average, running this monitor will cost you $2 because the monitor consumes only around 24 W of electricity.
Pro Accurate colors
The monitor is suitable for media editing applications in the sRGB color space because the 25UM58-P can accurately display 99% the sRGB color gamut. You can use this monitor, for example, in web design since all the web applications use sRGB as a default color space.
Pro Good for widescreen gaming
The monitor's extended field of view can give you some actual advantage in games such as Battlefield 1 and Team Fortress 2 which offer a broader field of view for those running 21:9 monitors.
Pro Can be locked
You can be sure that no one borrows the LG 25UM58-P from your work desk without you knowing it because this monitor has a Kensington lock.
Pro Decent viewing angles
The LG 25UM58-P does look good from an angle because of its high-quality IPS panels. While the exact numbers for the 25UM58-P are still not available, the entire line-up of the LG’s ultrawide monitors from 2016 and 2017 suggests that the maximum, horizontal viewing angle of this monitor should be higher than 40 degrees.
Pro Suitable for casual gaming
High responsiveness and proper motion handling make the LG 25UM58-P a suitable companion for enjoying an occasional CS:GO or Overwatch round.
The monitor feels responsive because of its 9 ms input lag. Only a handful of other general purpose monitors in this price range can match such high responsiveness.
The motion appears clear and almost free from the artificial motion blur effect because even the most rapidly-moving objects leave just some minor trails as the panel's pixels need only 5 ms to change their colors.
Pro Excellent value for money
Priced just a bit above $150, this 25-inch ultra-wide monitor offers a generous amount of on-screen workspace, good picture quality, decent gaming performance, and some premium functions, like LG's On Screen Control and the Split Screen feature. You’ll struggle to find the LG 25UM58-P a matching competitor in its price range.
Pro Lots of on-screen real estate
This monitor has enough workspace for you to edit two Word documents side by side - something you could never do on a 25-inch FHD monitor comfortably.
Additionally, the large workspace does not come at the cost of resolution as the LG 25UM58-P offers 20% higher pixel density compared to the regular 25-inch FHD panel.
Pro Nice for watching media
You won't see the black bars on the top and bottom of the screen while watching media filmed in the widescreen cinema standard because of the monitor's near-cinematic resolution of 2560x1080.
An aspect ratio of 21:9 is currently the de facto standard in the film making industry.
Pro Good picture quality
The monitor's contrast ratio, brightness, and color gamut are on par with what the vast majority of competitors in this price range offer.
The LG 25UM58-P can display rich images, with eye-catching and vivid colors and deep dark spots. The colors look good because of the monitor's peak brightness of 250 nits and the full support of the sRGB color gamut. Dark scenes appear deep thanks to the native contrast ratio of 1000:1, which pushes the monitor's blacks to reasonably intense levels.
Moreover, the LG 25UM58-P produces sharper and more saturated images than the corresponding 25-inch FHD competitors because it has 20% higher pixel density.
Pro Excellent for general usage
The LG 25UM58-P is one of the most versatile monitors in its price range because of its good picture quality, a massive amount of on-screen workspace, and the near-cinematic aspect ratio of 21:9.
Additionally, the monitor is suitable for casual gaming.
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 Bad for dark rooms
The monitor doesn't look good in dark rooms because its panel can't absorb all the light emitted by the backlight. Such effect is called backlight bleeding. Note that this is a widespread problem for most monitors in this price range.
Con Requires calibration
To pull the monitor's maximum color accuracy, you need to get it calibrated because the LG 25UM58-P lacks factory calibration. The calibration is required only if are going to do some color-critical work in the sRGB color space.
Even though the calibration process itself is not complicated, it’d require you to have the specific testing equipment. The usual rental price of such equipment is around $10 a day.
Con Lacks some adjustability
Setting up an ergonomically correct workspace might cause you a bit of a hassle because the monitor does not have a height or swivel angle adjustment.
Also, there is no way to use this monitor in a portrait mode since its stand does not support it.
Con Can't fight glare
The monitor doesn't look good in overly bright rooms with lots of windows as its backlight can't get bright enough to fight glare and heavy reflections.
Con Has an external power brick
You'll need to find a space for the monitor's PSU because the LG 25UM58-P comes with a bulky external power brick.
