The LG 27UD58 is one of the most affordable 4K monitors yet it offers vibrant colors, crisp details, a smooth performance, and plenty of useful features.
The LG 27UD58 is one of the cheapest 4K IPS monitors available. It offers an incredible image quality with vibrant colors and eye-catching detail clarity.
It’s a great pick for everyday use, casual gaming (console and PC), and even entry-level content creation.
The LG 27UD58-B monitor features an AH-IPS panel with 10-bit color depth support through dithering (8-bit + FRC), and it’s factory-calibrated to cover over 99% of the sRGB color space which means that you get accurate, consistent, and vibrant colors.
Further, 4K Ultra HD resolution displayed on a 27-inch screen results in a rich pixel density of 163 pixels per inch.
Naturally, you will need to scale your interface by at least 150% to enlarge small items such as text to a readable size, which will, in turn, decrease the amount of screen space but increase detail clarity.
Keep in mind that 4K is quite taxing on your GPU/CPU when it comes to PC gaming, so make sure you have the proper PC gear to run your favorite games without any issues.
Other panel-related specs of the LG 27UD58 include a 1,000:1 contrast ratio, a 250-nit peak brightness, a 5ms (GtG) response time speed, and wide 178-degree viewing angles for a flawless viewing experience no matter the angle you’re looking at the screen.
Our LG 27UD58 unit showed no excessive backlight bleeding and IPS glow, nor any other defects such as dead/stuck pixels.
It has a flicker-free backlight, so those sensitive to flickering won’t get headaches after prolonged use. There’s also a low-blue light mode which filters out the harmful low-blue lights.
Moving on to the performance, the LG 27UD58 4K monitor has a very low input lag of 9ms, which makes for an imperceptible delay between your actions and the result on the screen.
The 5ms response time speed i.e., the speed at which pixels can change from one shade of gray to another, is enough to get rid of most of the trailing caused by fast-moving objects for a smooth, fast-paced gaming experience at 60Hz.
Of course, a 144Hz refresh rate would be a lot smoother, but 4K 144Hz displays are a lot more expensive.
That’s why most PC gamers opt for 1440p 144Hz displays instead as they offer a good balance between image quality and performance without breaking the bank.
The LG 27UD58 also supports AMD FreeSync, which offers a variable refresh rate (VRR) when connected to a compatible graphics card. It supports VRR only over DisplayPort, though, so it cannot be used with the Xbox One.
There are two FreeSync modes: Basic (48-60Hz VRR range) and Extended (40-60Hz). We managed to get FreeSync to work with an NVIDIA card, but only in the Basic mode, which may be narrow, but it’s still better than nothing.
Apart from FreeSync, the LG 27UD58 is equipped with plenty of useful features such as Screen Split (divides the screen into parts for easier multitasking) and On-Screen Control (a desktop application that allows you to adjust the OSD settings).
The OSD (On-Screen Display) menu can also be navigated via the joystick that’s placed beneath the bottom bezel.
Other features include Black Stabilizer (increases visibility in darker games), and pre-calibrated picture presets (two FPS modes, RTS, Custom, Photo, Cinema, Reader, Dark Room, and Color Weakness).
Additionally, you will find Dynamic Action Sync, which bypasses certain video post-processing to minimalize input lag. Standard adjustments such as contrast/brightness, gamma, sharpness, color temperature, etc.
Design & Connectivity
The design of the LG 27UD58 is fairly simple. It has a stylish glossy black finish with reasonably thick bezels that will match any environment, be it a gaming setup or an office cubicle. The stand can only be tilted by -2°/18°, but you can VESA mount the screen via the 100x100mm pattern.
Connectivity options include two HDMI 2.0 ports, DisplayPort 1.2, and a headphones jack. All display connectors support HDCP 2.2, so you can watch copy-protected content from streaming services such as Netflix in native 4K UHD resolution.
When using the monitor with 4K consoles, make sure the HDMI Ultra HD Deep Color option is enabled in OSD. Lastly, the screen has a matte anti-glare coating, which eliminates reflections.
Price & Similar Monitors
The price of the LG 27UD58 is usually around $300. On Amazon, you will also find the 24″ model of this monitor, the LG 24UD58, which is sometimes available under $250.
We recommend investing ~$30 more for the ASUS VG289Q.
It has a slightly larger 28″ screen with a wider color gamut for more saturated colors. Further, it supports AMD FreeSync over both HDMI and DisplayPort, and it has a more modern design with thin bezels and full ergonomic support.
