Unboxing the LG UltraGear 27GP850-B gaming monitor

The LG UltraGear 27GP850-B is a relatively large monitor, and its box matches its size. Made of thick cardboard to withstand delivery, it features large stylized images of the monitor on both sides. You know that you’re looking at a gaming monitor from the first encounter.

Inside the package, LG bundled everything you need to mount and quickly start using the monitor. You get the monitor itself - disassembled in three parts: screen, leg, and desk support - together with various documents, a driver disc, cables (HDMI, USB 3.0 Type-A to B, DisplayPort), and the corresponding power adapter.

What's inside the box when you buy an LG 27GP850-B

Unboxing the LG UltraGear 27GP850-B monitor is a very pleasant experience. The tough protective box includes everything you need to use the monitor as soon as you unpack it, and the monitor itself looks good. Overall, it made a very good first impression.

Design and hardware specifications

The LG UltraGear 27GP850-B is a flat LCD monitor, and its thickness is relatively average: 5.17 centimeters (2.03 inches), which is more than most professional displays but definitely thinner than some bigger gaming screens. The 16:9 display has a 27 inches diagonal, while the whole screen measures 61.42 centimeters (24.18 inches) in length and 36.48 centimeters (14.36 inches) in height. Its support increases the monitor’s footprint on the desk to 29.12 centimeters (11.46 inches). Also, depending on how you prefer to use it, the monitor’s leg allows you to adjust its height to anywhere between 46.59 and 57.59 centimeters (18.34 and 22.67 inches, respectively).

The monitor can also tilt from -5° to 15° vertically, and it’s VESA-compatible (100 x 100 mm). In the latter case, it’s important to know that the LG UltraGear 27GP850-B weighs 4.2 kilograms (9.26 pounds) without the desk support, so you won’t have trouble finding a compatible VESA mount if you intend to place the monitor on a wall or a desk monitor arm.

The LG UltraGear 27GP850-B uses a high-performance 10-bit Nano IPS panel with a 1440p resolution (2560 x 1440 pixels) and a fast refresh rate of 165 Hz that can be overclocked to an even faster 180 Hz. In addition, the response time can also be set to 1 ms! The panel covers 98% of the DCI-P3 color gamut, which means approximately 135% of the sRGB color space. In other words, you get vivid colors and above-average saturation, which is probably what you want in games though not so much for professional work where color accuracy is essential.

The LG 27GP850 has a minimum brightness of 350 cd/m2, the typical one is advertised to reach 400 cd/m2, and the standard contrast ratio offered is 1000:1. The viewing angles are generous, as is the norm with any IPS panel, equalling 178 degrees both horizontally and vertically.

Regarding design, I can tell you that both the back of the screen, the desk stand, and the monitor’s leg look quite nice, all featuring black as the dominant color and red for emphasis. The materials used by LG are mostly plastics, keeping the price reasonable, but the inside framing is metallic, as proved by the joints, where you can see the endings and the screws that hold everything together.

Everything is matte, both the plastics and the screen’s coating. That’s something I appreciate as it helps decrease glare and reflections on the screen, as well as smudges and fingerprints on the bezels, desk stand, and otherwise on the monitor.

The back of the monitor is home to a generous selection of input and output ports. You get two HDMI 2.0, one DisplayPort 1.4, one upstream USB 3.0 Type-B, and two downstream USB 3.0 Type-A. In addition, there’s also a 3.5 mm headphone jack and the power input.

Last but not least, in terms of hardware specs, it’s important to note that the LG 27GP850 is definitely a gaming monitor: it supports both Nvidia’s G-Sync and AMD’s FreeSync (Premium) technology. To benefit from either, make sure you use a DisplayPort cable, not an HDMI one.

Using the LG UltraGear 27GP850-B gaming monitor

While I don’t have professional equipment to test and measure things like real-life color accuracy, contrast, response time, etc., I can tell you my subjective opinion on what using the LG UltraGear 27GP850-B gaming monitor is like.

First of all, even if this is a gaming monitor, I’ll tell you about my work days. In the week I had it on my desk, I used the LG UltraGear 27GP850-B for writing articles (and this review), as well as for playing games (Horizon Zero Dawn and League of Legends).

For the office part of the day, I found the monitor to be surprisingly well balanced. The most important thing for me in a monitor, besides a relatively large size, is how well it displays text. Obviously, because I read a lot and I write a lot, too. The LG UltraGear 27GP850-B manages to be great for both things: the 1440p resolution paired with the 27” diagonal size means I get smooth fonts on web pages and a reading experience that’s not tiring to the eye. After eight to ten hours of watching my monitor and my smartphone, I could still play an hour or two of my favorite games without feeling my eyes tired. That’s a big plus for me.

At the end of the day, I also enjoyed gaming, and yes, the LG UltraGear 27GP850-B really is a good gaming monitor. The 1440p resolution is great on a 27-inch monitor like this one: it offers the best balance when it comes to image quality, as the pixels are small enough to make the image look smooth, while the monitor still has a relatively large physical size. And, in games, the fast 165 Hz refresh rate is more than a regular gamer will probably ever need. 180 Hz and more really goes into the esports territory from my point of view. By the way, in Horizon Zero Dawn, the game I play obsessively these days, I didn’t notice any motion blur or any sort of trailing/ghosting. Considering that it also supports Nvidia G-Sync and AMD Freesync, I believe this monitor is an excellent choice for mid-range gaming.

Furthermore, there are a couple of other things I like about this monitor: the adjustment options, the OSD menu and navigation, and the USB hub on its back. The LG 27GP850 lets you adjust the screen height and tilting, something I find very helpful. It permits me to keep a more natural, ergonomic posture while working, which is vital for a 40-year-old like me. 🙂

The USB ports are handy too for me, as I get to connect both my keyboard and mouse directly to the monitor. The latter is something I want from my monitor because I’m also using a standing desk, and that helps quite a lot with cable management.

The USB ports on the back are very useful

And finally, I always like it when manufacturers choose to offer a miniature joystick controller for the onscreen display (OSD). Menus are much easier to navigate with a joystick as opposed to the traditional buttons found on the vast majority of computer monitors. Fortunately, LG did just that: the small power button under the screen also acts as a joystick.

Overall, I like the LG UltraGear 27GP850-B a lot. It offers top-notch performance, vivid colors, plenty of gaming features, and an attractive design. For its price, I believe it’s an excellent choice for anyone out there looking for a 27” 1440p gaming monitor.
