Overview
The LG UltraGear 27GP850-B is a 27-inch QHD (2560 x 1440) gaming monitor built around a Nano IPS panel, with a native 165Hz refresh rate and overclockable support up to 180Hz. Released in 2021 and still listed on LG Australia's official product page, it sits in a well-established segment of the AU gaming monitor market — the value-oriented 1440p IPS panel — and has shown consistent interest from Australian buyers, with documented recurring deal activity on community deal-sharing sites for the model.
This review is based on verified product documentation from LG's official channels and an official LG IT product portal specification sheet. It is not based on hands-on testing.
Who This Monitor Suits
Based on the verified specifications, the 27GP850-B is most relevant to:
- Australian PC gamers building or upgrading around a 1440p target resolution, particularly where an RTX 4070-tier build is the reference point. The QHD panel at this price band has been highlighted in Australian buyer guidance as a practical match for that tier.
- Buyers who want a flat, wide colour-gamut IPS panel rather than a curved VA screen — the 27GP850-B is a flat Nano IPS panel with a typical DCI-P3 gamut coverage of 98% and factory colour calibration.
- Multi-system users who want both DisplayPort and HDMI connectivity on the one desk, including a dual-HDMI setup alongside a DisplayPort connection for a primary GPU.
- Tilted, height-adjustable stand users — the supplied stand supports tilt, height, and pivot adjustment, and the panel is VESA-compatible (100 x 100 mm) for alternative mounting.
It is less obviously a match for:
- Buyers who specifically need built-in speakers — this model does not include them.
- Buyers whose primary inputs are limited to HDMI and who need the full 165Hz (or 180Hz overclock) at QHD resolution from an HDMI source alone — the HDMI 2.0 ports top out at 144Hz at QHD.
- Buyers seeking a curved screen, a higher-tier HDR certification above DisplayHDR 400, or USB-C video input — none of those are part of this model's verified feature set.
Verified Strengths
1. Colour performance for an IPS panel in this price band
The standout verified spec on paper is the typical DCI-P3 coverage of 98% (CIE1976), with a minimum of 90%. This is backed by LG's official Canadian product page and is consistent across the official sources reviewed. For an IPS panel, 98% DCI-P3 is well above the sRGB-only expectation many buyers have for gaming monitors in this segment, and it is one reason the model has been referenced in Australian buyer guidance as a notable value proposition at the A$449 price point.
The panel is also factory colour calibrated and supports 10-bit colour (1.07 billion colours) on paper, which supports the colour-accuracy framing more than a standard 8-bit IPS panel would.
2. Refresh rate and adaptive sync on a single DisplayPort connection
The panel's native refresh rate is 165Hz, overclockable to 180Hz, and the DisplayPort 1.4 port supports the full 2560 x 1440 at 165Hz, with overclock to 180Hz. For the primary gaming connection, that is the headline figure buyers are usually looking for.
The panel also carries both major adaptive sync credentials: NVIDIA G-SYNC Compatible and AMD FreeSync Premium. For buyers with either an NVIDIA or AMD GPU, the adaptive sync support is there on paper without needing a dedicated G-SYNC module.
3. Flat Nano IPS panel with anti-glare surface
The 27GP850-B uses a Nano IPS panel with an anti-glare surface treatment, which is the panel family LG uses to improve colour expression and viewing angles relative to conventional IPS in its gaming range. Viewing angles are listed at 178° R/L and 178° U/D, typical for this panel type. The screen is flat, not curved.
4. Ergonomic stand and VESA compatibility
The included stand offers tilt, height, and pivot adjustment — useful for a monitor in this class where many competitors in the same price band ship with a fixed or tilt-only stand. The panel is also VESA-compatible (100 x 100 mm) for arm or wall mounting.
5. Reasonable connectivity for multi-device use
The rear I/O includes:
- 1x DisplayPort 1.4
- 2x HDMI 2.0
- 1x USB 3.0 upstream + 2x USB 3.0 downstream
- 3.5mm headphone output (sound only)
For a gaming desk with a PC and a console, the two HDMI ports and one DisplayPort are a practical combination. The USB hub supports a basic upstream/downstream arrangement for peripherals. The headphone jack is a small convenience for late-night gaming without a separate headset setup on the desk.
6. Support for in-monitor gaming features
LG lists an extensive set of on-screen gaming features for this model: Black Stabilizer, Crosshair, Dynamic Action Sync, FPS Counter, HDR Effect, Motion Blur Reduction, Reader Mode, Flicker Safe, Smart Energy Saving, and a User Defined Key. These are monitor-side processing features rather than panel improvements, but they are a real differentiator against panels that offer no on-screen adjustment tools at all.
Trade-offs and Limitations
These are drawn directly from the verified specification set rather than from testing.
1. HDMI is capped below the DisplayPort ceiling
At QHD, each HDMI 2.0 port supports a maximum of 144Hz, while the DisplayPort 1.4 supports the full 165Hz and the 180Hz overclock. If you are pinning your gaming refresh rate to 165Hz or 180Hz, DisplayPort is the required connection. That is not unusual for HDMI 2.0 at QHD, but it is worth knowing if your setup relies on HDMI — for example, a console that does not expose a DisplayPort option.
2. DisplayHDR 400, not a higher HDR tier
The panel is certified to VESA DisplayHDR 400, with a typical peak brightness of 400 cd/m² and a minimum of 320 cd/m2. DisplayHDR 400 is the entry tier of the VESA HDR certification programme — it confirms the brightness floor and basic HDR metadata support, but it is not the same as the brighter HDR400/600/1000 tiers some buyers look for in a "premium" HDR gaming monitor. If HDR impact is a primary purchase driver, this panel's HDR credentials are modest rather than standout.
3. No built-in speakers
The panel does not include built-in speakers. You will need separate headphones or external speakers for audio. The 3.5mm headphone output provides a sound-only output for headphones.
4. 1000:1 typical contrast is IPS-standard, not VA-level
The typical contrast ratio is 1000:1, with a minimum of 700:1. That is standard for an IPS panel and is lower than what many VA panels can deliver. For buyers who prioritise deep blacks above colour and refresh performance, a VA alternative may be more appealing on contrast alone — though that is a trade-off across the whole feature set, not a weakness in isolation.
5. Gaming feature set is monitor-side processing, not a substitute for panel quality
The large list of on-monitor gaming features is useful, but features like Motion Blur Reduction and HDR Effect are post-processing aids rather than underlying panel improvements. They can be helpful, but they do not change the underlying panel's response time or contrast characteristics.
6. 2021 release — not a current-generation panel
The model was released in 2021. It remains available through LG Australia and has active AU deal history, but it is not a 2024 or 2025 release. For buyers comparing it against newer panels in the same size and resolution class, the purchase decision is partly about whether the verified feature set still holds its own rather than assuming it represents the current best-in-class.

Buying Considerations
Connection choice matters for the highest refresh rate
If your goal is the full 165Hz (or 180Hz overclock) at QHD, use DisplayPort 1.4 from your GPU. HDMI 2.0 is perfectly serviceable for 144Hz at QHD, but it does not carry the panel's top refresh figure on its own. This is a practical distinction for buyers who are thinking about the highest refresh they can extract from the panel.
Colour and HDR are two different stories
On paper, this panel's colour story — 98% DCI-P3, factory calibration, 10-bit colour — is stronger than its HDR story. DisplayHDR 400 is a real certification, but it sits at the entry end of VESA's HDR tiers. Buyers who care most about colour volume for games and content may find the panel's colour specs more relevant than its HDR headline. Buyers who want the most impactful HDR from a monitor in this size class may want to look at what higher HDR tiers offer and weigh that against the rest of the feature set.
Stand ergonomics are above-average for the price band
The tilt, height, and pivot adjustability on the included stand, plus VESA compatibility, is a meaningful plus if you compare against competing panels in the same broad segment that ship with tilt-only stands. If you plan to use a monitor arm anyway, the VESA mount means the supplied stand is optional rather than limiting.
Multi-input households get practical use from the two HDMI ports
For a desk that mixes a gaming PC and a console, or a secondary device, the two HDMI 2.0 ports are convenient. Just remember that neither HDMI port reaches 165Hz at QHD — so a console that targets a lower refresh rate is fine on HDMI, but a high-refresh PC gaming setup is best on DisplayPort.
Deal history and Australian availability
The model has shown repeated Australian deal activity — including community deal posts with significant upvote volume — and remains listed on LG's Australian product page. That does not guarantee any particular current price, but it does indicate the model is not a hard-to-find import in the AU market and has an active buyer base. The A$449 price point has been referenced in Australian buyer guidance for this model; treat any specific price as a point-in-time figure and verify it at checkout.
Comparison Context: Nano IPS vs Conventional IPS vs VA
Because this panel's identity is "Nano IPS, flat, 165Hz, 1440p," it helps to be clear about what that does and does not imply relative to other common gaming monitor panel types.
| Factor | Nano IPS (27GP850-B) | Conventional IPS gaming panel | VA gaming panel | |---|---|---|---| | Colour gamut on paper | DCI-P3 98% typical | Typically sRGB-focused | Varies; often sRGB-oriented | | Contrast ratio (typical) | 1000:1 | ~1000:1 | Often higher (deeper blacks) | | Response time (fast mode) | 1ms GtG on paper | Similar 1ms GtG claims common | Can be slower in practice than IPS | | Refresh rate | 165Hz native, O/C 180Hz | Common in this class | Available, but panel suitability varies | | Adaptive sync | G-SYNC Compatible + FreeSync Premium | Frequently available | Frequently available | | Viewing angles | 178° R/L, 178° U/D | Strong | Can be narrower than IPS | | Screen shape | Flat | Flat or curved | Flat or curved | | Built-in speakers | No | Variable | Variable |
What this means in practice:
- Nano IPS vs conventional IPS: The Nano IPS label is LG's branding for a panel with improved colour expression relative to a basic IPS panel. The 98% DCI-P3 figure here is the clearest evidence-backed differentiator — a conventional IPS panel in the same price band is less likely to reach that level of colour gamut on paper.
- Nano IPS vs VA: The trade-off is colour/viewing angle/speed versus contrast. The 27GP850-B offers stronger colour gamut and IPS-style viewing angles; a VA panel in the same size class typically offers deeper blacks and higher contrast on paper, but may introduce more motion blur or slower response in fast scenes. Which is "better" depends on whether the buyer prioritises colour and speed or contrast and black levels.
There is no single winner here on the available evidence — the right choice depends on whether the buyer values the Nano IPS colour and speed profile or wants the deeper contrast a VA panel can provide.
Verdict
On the verified evidence available, the LG 27GP850-B is a well-specified 27-inch 1440p gaming monitor whose strongest, most defensible claims are its Nano IPS colour performance, 165Hz (overclockable to 180Hz) refresh via DisplayPort, G-SYNC Compatible and FreeSync Premium support, and an above-average ergonomic stand for the segment. The 98% DCI-P3 typical gamut and factory colour calibration are the clearest points in its favour for buyers who care about colour as well as gaming performance.
The limitations are equally real and evidence-based: DisplayHDR 400 is an entry-level HDR claim rather than a premium one, HDMI tops out at 144Hz at QHD, there are no built-in speakers, and the 1000:1 typical contrast is IPS-standard rather than VA-level. For a buyer whose priorities are colour, refresh rate, and a flexible stand on a flat IPS panel, the 27GP850-B holds together well on paper. For a buyer whose priorities are deep blacks, high-impact HDR, or a built-in speaker solution, the evidence suggests looking at alternatives before assuming this panel is the right fit.
