Overview
The LG UltraGear 27GS85Q-B is a 2024-model 27-inch gaming monitor built around LG's Nano IPS panel technology, targeting the competitive sweet spot between fast-paced gameplay and colour-accurate visuals. It succeeds the popular 27GP850-B with a higher native refresh rate, VESA AdaptiveSync certification, and the addition of a USB 3.0 hub — changes that collectively address some of the predecessor's most common buyer requests without pushing the price upward.

Who This Monitor Is For
The 27GS85Q-B is aimed at PC gamers who want more than a budget 1080p panel but aren't ready to invest in a premium OLED or 4K display. Specifically, it suits:
- Competitive and mid-tier gamers who need a fast, smooth experience (180Hz native, 1ms GtG) without sacrificing image quality entirely
- Multi-GPU-household setups, since it carries both NVIDIA G-SYNC Compatible and AMD FreeSync certification alongside the broader VESA AdaptiveSync standard — one monitor that works cleanly with either camp
- Buyers upgrading from a 27GP850-B who want a meaningful spec bump without a price increase
- Users who also want a capable colour gamut for creative work alongside gaming — the Nano IPS panel's near-P3 colour coverage (98% DCI-P3 typical, 90% minimum, both measured in the CIE1976 colour space) makes it more versatile than a typical gaming-only TN or VA panel
It is a 27-inch, 16:9 format monitor at 2560 × 1440 (QHD), which at 109 PPI delivers noticeably sharper image density than a 27-inch 1080p screen. At that resolution, mid-range GPUs can still achieve frame rates that make 180Hz genuinely useful in many titles.
Verified Strengths
Panel and Colour
The Nano IPS technology underpins the key image quality story here. Nano IPS uses nanosized particles applied to the LED backlighting to widen the colour gamut beyond what standard IPS achieves. LG's verified specs for the 27GS85Q-B show a typical colour gamut of 98% DCI-P3 (CIE1976), with a minimum guaranteed figure of 90% DCI-P3 — an important distinction, since monitors with wide typical coverage can vary in consistency. The 10-bit colour depth (1.07 billion colours) further supports the colour story, and the unit ships with factory colour calibration included.
Refresh Rate and Response Time
The native 180Hz refresh rate is the headline specification, with an overclocked mode at 200Hz available via DisplayPort 1.4. The verification notes confirm that 200Hz requires DisplayPort — it is not achievable over HDMI. LG rates the response time at 1ms GtG, but the verification records clearly note this figure applies specifically when the OSD is set to "Faster Mode." Buyers should be aware that response time mode selection involves a trade-off with potential overshoot artefacts; LG provides multiple response time presets in the OSD for this reason.
Adaptive Sync Breadth
VESA AdaptiveSync certification, NVIDIA G-SYNC Compatible status, and AMD FreeSync support together cover the widest possible range of GPU pairings. The verification notes flag that AMD FreeSync is available over DisplayPort only — not HDMI — which is a relevant detail for console users or PC builders routing through HDMI.
Connectivity and USB Hub
The connectivity loadout is solid for the class: two HDMI 2.0 ports (HDCP 2.3), one DisplayPort 1.4 (HDCP 2.3), a 3.5mm headphone output, and a USB 3.0 hub comprising one USB-B upstream and two USB-A downstream ports. The USB hub addition distinguishes the 27GS85Q-B from its predecessor and is a practical convenience for desk setups where the monitor acts as a central connection point.
Ergonomics
The stand supports tilt (−5° to +15°), 110mm height adjustment, and clockwise pivot to portrait orientation. The VESA mounting pattern is 100 × 100mm for those preferring a third-party arm. The three-side virtually borderless design suits multi-monitor arrangements.
HDR
The monitor carries DisplayHDR 400 and HDR10 certification. DisplayHDR 400 is the entry-level tier of the VESA DisplayHDR standard, requiring a minimum peak brightness of 400 cd/m². LG's verified specs show a typical brightness of 400 cd/m² with a minimum of 320 cd/m², which aligns with that certification tier.
Eye Care Features
LG includes Flicker Safe (DC dimming), a Reader Mode, and a Colour Weakness mode in the software feature set.
Software
OnScreen Control (LG Screen Manager) is included for software-side display management.
Trade-offs and Limitations
HDR performance ceiling. DisplayHDR 400 is an entry-level certification. Buyers expecting dramatic HDR highlights or deep blacks should be aware that this tier has material limitations compared to DisplayHDR 600 or higher, and compared to OLED panels with near-infinite contrast ratios. The native contrast ratio is rated at 1000:1 typical (700:1 minimum), which is characteristic of IPS-class panels. IPS panels generally cannot match the deep blacks of VA or OLED displays.
HDMI bandwidth constraints. Both HDMI ports are version 2.0, not 2.1. HDMI 2.0 has sufficient bandwidth for 1440p at up to 144Hz, but not 180Hz or 200Hz. At the native 180Hz, DisplayPort is required. Console users connecting current-generation hardware should note this carefully; they will be limited in what frame rate or resolution combinations HDMI 2.0 can carry.
Adaptive Sync and FreeSync over DisplayPort only. As confirmed by the verification notes, AMD FreeSync (and by extension, the full G-SYNC Compatible variable refresh experience) operates over DisplayPort. HDMI connections lose that feature.
External power adapter. The power supply is an external adapter rather than an internally housed unit. This is a minor desk-management consideration rather than a performance factor. Power consumption is rated at 32.16W on-mode, with ErP-mode consumption of 26W — modest figures for a 27-inch QHD display.
No built-in speakers. The specifications list a 3.5mm headphone output but no built-in speaker system. Buyers relying on monitor speakers should factor in a separate audio solution.

Buying Considerations
DisplayPort is the primary gaming connection. To use 180Hz, 200Hz, or AMD FreeSync, you need to be on DisplayPort 1.4. If your PC only has HDMI outputs or you are connecting a current-generation console, confirm the bandwidth and feature limitations before purchasing.
Response time mode trade-offs. The 1ms GtG figure is tied to Faster Mode. If you notice overshoot or inverse ghosting at that setting, the OSD provides alternative modes to tune. LG's Dynamic Action Sync (DAS) and Black Stabiliser are additional gaming features accessible through the OSD.
Factory calibration value. The inclusion of factory colour calibration is a meaningful addition for buyers who intend to use this monitor for colour-sensitive creative work alongside gaming. It suggests the unit ships closer to accurate colour targets out of the box, though individual panel variation always exists.
USB hub usefulness depends on your setup. The USB 3.0 hub requires the USB-B upstream cable to be connected to your PC for the downstream ports to function. It is a convenience feature rather than a standalone one.
Overclocking to 200Hz. The 200Hz mode is achieved through overclocking via DisplayPort. LG ships the monitor with this capability, but overclocked modes are by definition operating outside the panel's native rated specification. The practical stability and visual difference between 180Hz and 200Hz will vary.
Verdict
The LG UltraGear 27GS85Q-B occupies a well-defined position: a Nano IPS gaming monitor that delivers a wider colour gamut and more versatile GPU compatibility than many competitors in the class, at a native 180Hz with an overclock path to 200Hz. The USB hub addition over its predecessor is a practical improvement, and VESA AdaptiveSync certification alongside both G-SYNC Compatible and FreeSync support makes it a genuinely GPU-agnostic choice.
The trade-offs are real but largely characteristic of the class and price tier: DisplayHDR 400 is entry-level HDR, HDMI 2.0 limits HDMI-connected users to below 180Hz, and the IPS contrast ratio will not satisfy buyers who prioritise deep blacks. There are no built-in speakers.
For a PC gamer seeking a QHD 180Hz Nano IPS panel with broad adaptive sync support, factory calibration, and a USB hub — the 27GS85Q-B makes a coherent case. Buyers with specific requirements around HDMI bandwidth, HDR performance, or contrast depth should weigh those limitations against the competing options available at a similar price point.
