Cons
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.
Con Requires calibration
To get the most out of the monitor’s performance, you need to calibrate it. The procedure will take you 5-10 minutes as the monitor’s optimized ICC profile is available on the Internet.
Con Lacks speakers
Not a huge dealbreaker, but it's something to consider.
Con Not suitable for Adobe RGB content
This monitor is not the right tool for those who work with Adobe RGB as it supports only 70% of the Adobe RGB colors.
Con Doesn’t look good in a dark room
In a dark room, you can notice some minor backlight bleeding that occurs towards the lower part of the screen. Backlight bleeding appears when the panel can’t absorb the 100% of the monitor’s backlight and limits the monitor’s use in a dark environment.
However, this is a widespread issue for the IPS panels in this price range.
