The LG 27UD58-B is a good 4k IPS gaming monitor with passable picture quality. It has a few gaming-oriented features such as FreeSync and very low input lag for a 60Hz monitor. Motion handling is also good but limited by the relatively low refresh rate. Unfortunately, backlight bleed is bad when viewed in a dark room and the reflection handling isn't as good as some other monitors when viewed in a bright room.
Our Verdict
The LG 27UD58 is a decent monitor for mixed usage. Gaming-oriented features such as FreeSync and the low input lag result in good gaming performance, but the picture quality is only passable. The sides of the image do remain accurate when viewed from up-close due to the wide viewing angles, which is good.
- Input lag is very low.
- Solid colors and backgrounds are uniform.
- High resolution is great for multitasking.
- Blacks appear gray and blotchy.
- Prominent backlight bleed.
The LG 27UD58 is decent for office use. The limited ergonomic adjustments make it less convenient to show images to coworkers or to find a comfortable viewing position for long periods of time. The high resolution is a bonus for productivity and multitasking, which is good. The picture quality of the LG 27UD58-B is only passable, but the image remains accurate when viewed at an angle, which is good.
The LG 27UD58 is a good monitor for gaming. The combination of FreeSync, low input lag, and good motion handling results in a responsive and tear-free experience, which is good. Unfortunately, the 60Hz refresh rate limits the performance for fast-paced games and the picture quality is only decent.
The LG 27UD58 is a decent monitor for media consumption. Coverage of the most used sRGB color space is great, and the gray uniformity is good. The image also remains accurate when viewed at an angle, which is great. Unfortunately, the picture quality is only passable and is limited by the low native contrast ratio and poor black uniformity of the IPS panel.
The LG 27UD58 is decent for editing photos or videos. The out of the box image accuracy is great, and the image also remains accurate when viewed at an angle. Unfortunately, the low native contrast ratio and poor black uniformity reduce the picture quality.
The LG 27UD58 doesn't support HDR.

Differences Between Sizes And Variants
We tested the 27" model (27UD58B-P). However, the monitor is also available in 24" (24UD58B-P). It is also closely related to the higher end 27UD68, which is available in white (27UD68P-W) and black (27UD68P-B) variants.
If someone comes across a different type of panel or if their 27UD58B-P doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Popular Monitor Comparisons
The LG 27UD58B-P is a decent 4k monitor with an IPS screen and FreeSync support. It is one of the best gaming monitors under $300 we have tested. See our recommendations for the best monitors for Xbox One X and the best PC gaming monitors.
The LG 27UD68P-B is better than the LG 27UD58-B, but overall, performance is very similar between the two. The 27UD58-B has a fixed stand that has extremely limited flexibility, whereas the 27UD68P-B has a telescoping stand and can rotate between a portrait and landscape orientation. The 27UD58-B is brighter as well.
The LG 27UD58-B is better than the LG 29UM69G-B. The LG 27UD58-B has a 4K UHD resolution with more detail that makes it easier to multitask, like when you're creating media or watching multimedia while browsing the net. On the other hand, the LG 29UM69G-B has a slightly better refresh rate, a faster pixel response time, and supports black frame insertion (BFI) to clear up blur. All these features are good news for those who plan to use it for video gaming.
The LG 27UD58-B is much better than the Samsung UE590. The LG 27UD58-B has much wider viewing angles, and there are no duplications in moving objects as the backlight is flicker-free. The 27UD58 has better gray uniformity, which is great for watching streaming sports.
The LG 27UD58-B is slightly better than the Dell U2717D. The 27UD58-B has wider viewing angles and is better suited for gaming with much lower input lag and support for AMD's FreeSync technology. The higher resolution of the 27UD58-B makes it easier to multitask, but can be a bit more demanding on a PC. The Dell U2717D has far more ergonomic options, so it is easier to place it in a comfortable position.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
