LG 27GP850-B Ultragear Gaming Monitor Review
Summary
The LG 27GP850-B Ultragear Gaming Monitor brings together a 27-inch 2560 x 1440 Nano IPS display, a 165Hz refresh rate, NVIDIA G-SYNC Compatible support, and AMD FreeSync Premium for a listed $339.99. Its strongest case is the combination of picture quality, high-refresh gaming, wide viewing angles, and an adjustable stand—not uncompromising HDR performance. The advertised 180Hz overclock is best treated as a bonus because the supplied information notes that it may not work perfectly on every unit. Reports of light bleed in dark scenes also deserve attention. This review assesses the supplied specifications and reported strengths and weaknesses rather than independent hands-on measurements.

Not sure this is the right one? Answer 3 quick questions and CartGuide finds your top 3 picks in about 30 seconds.
Design and Everyday Adjustability
The LG 27GP850-B pairs its 27-inch screen with a matte surface and a stand offering tilt, height, and pivot adjustment. These are practical features for buyers who want control over screen positioning without choosing a monitor solely around gaming specifications.
A 27-Inch QHD Screen, Not an Ultrawide
The product description specifies a 2560 x 1440 resolution, while the specifications list a 16:9 aspect ratio. Those are the clearest supplied details for understanding the screen format: this is a conventional widescreen QHD monitor, not an ultrawide model.
One specification labels the resolution “QHD Ultra Wide 1440p,” which conflicts with the stated resolution and aspect ratio. Buyers should use the explicit 2560 x 1440 and 16:9 figures when deciding whether this monitor matches their needs, rather than interpreting that label as evidence of an ultrawide screen.
An Adjustable Stand and Matte Finish
Tilt, height, and pivot adjustment give the stand useful flexibility. Height and tilt let you change the screen’s position and angle, while pivot adds another orientation option. Good build quality and the adjustable stand are also identified as strengths in the supplied product information.
The matte screen surface is another relevant detail for everyday use, although no reflection-handling measurements are provided. Stand dimensions and adjustment ranges are not supplied either, so buyers with a tightly constrained desk setup should confirm those details before ordering.
Gaming Performance: 165Hz With an Optional Overclock
A 165Hz refresh rate is central to the LG 27GP850-B’s gaming appeal. The specification also lists an overclock to 180Hz and a 1ms gray-to-gray response time, but those figures should not be mistaken for independently verified performance in every operating mode.
Make 165Hz the Basis of Your Decision
The supplied assessment highlights the high refresh rate as a strength for smooth gaming. At its listed 165Hz setting, the monitor already offers the high-refresh capability that defines its positioning as a gaming display.
The 180Hz option is explicitly described as an overclock, and the supplied drawbacks warn that it may not work perfectly on all units. That makes 165Hz the more sensible basis for a purchase decision. If reliable operation at exactly 180Hz is essential to you, the stated uncertainty is a reason to reconsider.
What the 1ms Response-Time Claim Establishes
LG’s supplied specification lists a 1ms gray-to-gray response time. This is an advertised pixel-response figure, not a supplied measurement of overall input lag or proof that every transition completes at that speed.
No response-time test results, motion-artifact measurements, or recommended response settings are included. The honest conclusion is that the monitor has gaming-oriented specifications and reported smoothness, while the evidence here does not establish precisely how clean motion looks across different settings.
Picture Quality and HDR Limitations
Excellent picture quality and wide viewing angles are among the monitor’s supplied strengths. Its Nano IPS panel is therefore a major part of the appeal, but the listed contrast, brightness, and reported dark-scene issues place important boundaries around that recommendation.
Nano IPS Picture Quality and Viewing Angles
The 27-inch Nano IPS display combines QHD resolution with viewing angles identified as a positive in the supplied information. For buyers looking for both a gaming monitor and an appealing everyday display, that combination is more relevant than refresh rate alone.
However, no color-accuracy measurements, color-gamut figures, or calibration results are supplied. The reported excellent picture quality supports a favorable general assessment, but it does not establish suitability for color-critical professional work.
DisplayHDR 400 Does Not Remove the Caveats
The LG 27GP850-B lists VESA DisplayHDR 400, brightness of 400 cd/m², and a 1000:1 contrast ratio. The supplied drawbacks specifically identify limited brightness for true HDR performance, so the HDR designation should not be the main reason to buy this monitor.
Some reports also mention light bleed in dark scenes. That does not establish that every unit will show the same issue, but it is relevant if you are particularly sensitive to dark-scene presentation. Buyers prioritizing HDR impact or dark-room viewing should weigh these limitations more heavily than those focused chiefly on high-refresh gaming.
Adaptive Sync and Feature Priorities
NVIDIA G-SYNC Compatible support and AMD FreeSync Premium are both included in the supplied feature list. Alongside the adjustable stand and matte finish, these give the monitor a practical feature set, though several purchase-critical details remain unspecified.
Support for NVIDIA and AMD Gaming Setups
Having both NVIDIA G-SYNC Compatible and AMD FreeSync Premium listed is a useful consideration for buyers comparing adaptive-sync support. The monitor is not presented as offering only one of these two named compatibility options.
The supplied information does not state adaptive-sync operating ranges or connection-specific requirements. Confirm compatibility with your particular graphics hardware and intended connection rather than assuming that every feature operates identically in every setup.
Check Connectivity Before Committing
The strongest documented features are straightforward: QHD Nano IPS, 165Hz refresh, an optional 180Hz overclock, adaptive-sync support, and stand adjustment. Together, these describe a monitor focused on its display and gaming fundamentals.
The supplied facts do not identify ports, cable inclusions, audio features, or supported console modes. Their absence from this review does not mean the monitor lacks them; it means they cannot be assessed here. If a particular connection or console configuration is essential, verify it separately before purchasing.
Who Should Buy It—and Who Should Skip It
The LG 27GP850-B is most convincing when evaluated as a 27-inch QHD high-refresh gaming monitor. Its fit becomes less certain when the buying brief shifts toward demanding HDR, guaranteed overclocked operation, or specialized display requirements.
A Strong Match for QHD High-Refresh Gaming
This monitor belongs on the shortlist for buyers who specifically want a 27-inch 2560 x 1440 screen with a 165Hz refresh rate. Its reported picture quality and wide viewing angles make the case broader than speed alone, while both named adaptive-sync options add to its gaming appeal.
It is also worth considering if stand adjustment matters to you. Rather than accepting a fixed screen position as a trade-off for gaming specifications, you get tilt, height, and pivot adjustment as part of the listed package.
Less Suitable for HDR-First or Ultrawide Buyers
Buyers whose main priority is HDR performance should be cautious because the supplied assessment explicitly calls out a brightness limitation. Those especially bothered by light bleed should likewise take the dark-scene reports seriously, without assuming they describe every unit.
Skip it if you require an ultrawide format: the explicit specifications describe a 16:9 display. It is also a questionable match if guaranteed 180Hz operation is nonnegotiable, or if your purchase requires verified professional color accuracy that the supplied information does not establish.
Value at $339.99 and Alternative Categories
At the supplied price of $339.99, the LG 27GP850-B offers a clearly defined combination of resolution, refresh rate, panel type, and ergonomics. There is enough information to judge that package on its own terms, but not enough current competitor pricing to call it the best deal in its class.
Evaluate the Features You Will Actually Use
The value argument is strongest if QHD resolution, 165Hz refresh, adaptive-sync support, and an adjustable stand all match your requirements. In that case, several of the monitor’s documented strengths contribute directly to the purchase rather than serving as secondary extras.
The argument is weaker if you are buying mainly for the 180Hz overclock or the HDR designation. Both come with explicit caveats in the supplied information. Treating them as secondary features produces a more realistic assessment of what the listed $339.99 buys.
Compare Categories Without Assuming Their Specifications
Two useful comparison categories are 1080p high-refresh gaming monitors and premium HDR-focused monitors. The former is relevant if you are reconsidering whether QHD is necessary; the latter is relevant if the LG’s stated HDR limitation conflicts with your main priority.
No specific alternative models, prices, or test results were supplied, so the comparison below is a buying framework rather than a measured ranking. Check each alternative’s actual resolution, refresh rate, HDR evidence, and stand features before deciding that it offers better value.

The verdict
The LG 27GP850-B Ultragear Gaming Monitor is a compelling shortlist option at the supplied $339.99 price for buyers seeking a 27-inch QHD Nano IPS display with 165Hz refresh, NVIDIA and AMD adaptive-sync support, and a flexible stand. Its reported picture quality, viewing angles, and build quality support that recommendation, but the evidence does not justify calling it a class-leading bargain or a premium HDR performer. Buy it for its core QHD high-refresh package, treat 180Hz as an optional bonus, and weigh the reported light bleed carefully if dark-scene viewing is a major priority.
