None is universally best: price and stock vary by country, while room lighting, gaming platform, input, ergonomics and tolerance for panel-specific flaws can change the right choice.
What a 27-inch QHD monitor gives you
All three monitors in this guide pair a 27-inch diagonal with a 2560 × 1440 (QHD or 1440p) resolution. That combination gives office applications more working area than 1080p while remaining easier to drive than 4K at high refresh rates. Text, spreadsheets and browser layouts benefit from the extra pixels, and modern graphics cards can target high frame rates at 1440p without the performance demand of a 4K panel.

The models are gaming-capable rather than ordinary 60 Hz office displays. Their refresh rates run from 165 Hz to 180 Hz, so a compatible PC can show substantially more frames and smoother cursor and camera movement. You still need the right cable, graphics output and game settings to reach those rates; a high-refresh specification does not make every game run at that speed.
Panel technology matters as much as the headline resolution. The Dell G2724D and LG 27GR75Q-B use IPS panels, generally chosen for consistent viewing angles and versatile work use. The AOC Q27G3XMN uses VA with a Mini LED backlight, a design aimed at stronger HDR contrast in games but accompanied by a reported dark-scene smearing caveat.

Specifications above come from the manufacturers where identified; brightness, colour coverage and refresh figures are product specifications rather than independent measurements. RTINGS conclusions refer to its tested samples and published reviews, including a Dell test-bench update on February 21, 2025 and an LG review update on March 30, 2026. Regional suffixes can differ.
Dell G2724D: the balanced IPS option
What you get
Dell lists a 27-inch Fast IPS QHD panel, 165 Hz over DisplayPort and 144 Hz over HDMI. The same specification lists 400 cd/m² brightness and support for VESA Adaptive-Sync, G-SYNC Compatible and FreeSync Premium. Those input-specific refresh rates are important: connecting a PC by HDMI limits the display to the listed 144 Hz, while DisplayPort is required for 165 Hz.
Why it suits mixed use
RTINGS characterizes the G2724D as an entry-level gaming monitor with fast response, low input lag and common variable-refresh-rate formats. In its comparison with the LG, RTINGS reports that the Dell is brighter, handles glare better and has better motion handling. That combination makes it a practical single-screen solution for documents by day and fast games at night, especially in a room with windows or overhead lighting.

Trade-offs and buying cautions
The same review describes the Dell’s extra features and picture quality as basic. It is not a feature-rich creator display or a premium HDR monitor. Dell’s US listing was observed at $149.99 but temporarily out of stock when accessed in 2026. Treat that figure as a dated US availability snapshot, not as a permanent worldwide price or a promise that the monitor is currently obtainable.
Check the exact stand configuration and current official specifications before buying if height adjustment, swivel or pivot is important. The available evidence does not establish a full ergonomic comparison with the LG.
LG 27GR75Q-B: the desk-friendly IPS alternative
Specifications that matter for work
LG’s US product page specifies a 27-inch QHD IPS panel running at 165 Hz. It states 99% typical sRGB coverage and 95% minimum, and lists both G-SYNC Compatible and FreeSync Premium support. The stand explicitly adjusts for height, pivot and tilt, giving you more options for aligning the screen with a seated workstation or rotating it for portrait-oriented documents.
Where it falls behind the Dell
RTINGS calls the 27GR75Q-B a decent budget gaming monitor but reports that the Dell is brighter, better at rejecting glare and better in motion handling. RTINGS also reports PS5 VRR support for the Dell and not for the LG model it reviewed. If a PlayStation 5 is a primary source, confirm the exact console compatibility of the regional model before relying on variable refresh.

Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Who should choose it
Choose the LG when the stand’s height and pivot range solve a real desk problem, or when the local price and return terms are more favorable than the alternatives. Its stated sRGB coverage is useful for ordinary web and office work, but it is not a substitute for a factory-calibrated professional colour monitor. Current price and stock were not established in the available manufacturer and review material, so check a live local listing.
AOC Q27G3XMN: the gaming and HDR specialist
Mini LED is the reason to consider it
RTINGS’ 2026 budget-monitor roundup names the Q27G3XMN its best budget 27-inch gaming monitor in that roundup. The display uses a VA panel, QHD resolution and a maximum 180 Hz refresh rate. Its Mini LED backlight is the distinctive feature: more precise backlight control can make HDR game scenes look more impactful than a conventional edge-lit budget panel.
Rank #4
The dark-scene caveat
RTINGS’ 1440p gaming roundup also reports dark-scene black smearing. This can appear as trails behind moving objects in shadows or dark interfaces, a VA behaviour that may be noticeable in certain games and videos. Mini LED HDR strength does not make the monitor equivalent to an OLED display; bright highlights, local dimming behaviour and motion artefacts remain separate considerations.
When it is the right fit
Pick the AOC when gaming and HDR have priority over the most predictable office motion and text experience. If you spend many hours scrolling dark documents, editing in dark applications or playing shadow-heavy competitive titles, use the retailer’s return window as protection against a sample whose smearing is distracting. Verify the exact regional suffix, included cables, stand features and current adaptive-sync details before ordering.

1. Start with the exact local price and SKU
Monitor prices, inventory and suffixes change quickly. A US listing at a particular moment cannot establish the cheapest option in another country. Search for the complete model name, including any regional suffix, and compare the delivered price, tax, warranty and return period. Make sure the listing describes a new unit rather than an open-box or refurbished product if that matters to you.

2. Match the stand to your desk
If you need to raise the panel, rotate it for portrait work or fine-tune the viewing angle, the LG’s documented height, pivot and tilt adjustments are a clear selection point. For the Dell and AOC, confirm the current official stand specification rather than assuming that a similarly named revision has the same adjustment range. A VESA-compatible arm can solve a stand limitation, but check the monitor’s mounting pattern and the arm’s load range first.
3. Account for room light and glare
Brightness on a specification sheet is not the same as measured brightness in a review, and a bright panel cannot eliminate reflections from a window. RTINGS reports better glare handling for the Dell than the LG. Place any monitor so the strongest light is not directly behind you or reflected into your eyes, then use the display’s brightness control for comfortable text viewing rather than leaving it at maximum.
4. Choose the connection that delivers your target refresh
The Dell’s maximum depends on the input: DisplayPort reaches 165 Hz, while HDMI is listed at 144 Hz. LG lists 165 Hz, but the computer, cable and port still need to support that mode. The AOC is listed at up to 180 Hz; confirm which connector provides it on your exact unit. Older HDMI or DisplayPort cables, docks and adapters can silently limit refresh rate or resolution.
Recommended Free Tools
5. Check variable refresh for your platform
Variable refresh rate (VRR) synchronizes the panel’s refresh timing with a compatible graphics source, reducing tearing when frame rates fluctuate. Dell lists VESA Adaptive-Sync, G-SYNC Compatible and FreeSync Premium. LG lists G-SYNC Compatible and FreeSync Premium. RTINGS reports PS5 VRR support for the Dell and not for the reviewed LG. Console support can depend on firmware, resolution, cable and game, so confirm your console’s supported mode before purchase. For the AOC, verify the current regional documentation for the exact VRR formats you need.
6. Decide whether HDR or predictable office behaviour comes first
The AOC’s Mini LED backlight makes it the obvious candidate when HDR gaming is a primary goal, but its reported dark-scene smearing is a meaningful compromise. The Dell and LG are simpler IPS choices for mixed office and gaming work. Neither should be treated as a guaranteed premium HDR experience merely because a game or operating system offers an HDR toggle.

- Confirm the physical fit. Measure desk depth, stand footprint and viewing distance. Leave room for the cable bend and ventilation, and verify that the screen can be centred without blocking speakers or a webcam.
- Use the correct port. For the Dell’s full 165 Hz mode, connect through DisplayPort. Use the monitor’s supplied or certified cable where possible, and avoid an unverified adapter between the graphics card and display.
- Install or update the graphics driver. A current driver helps expose the monitor’s native 2560 × 1440 mode and VRR options. Restart after installation if the operating system does not show the new refresh choices.
- Select native resolution and refresh. In Windows, open Settings, System, Display, Advanced display, then choose 2560 × 1440 and the highest refresh rate available for the connected input. On other operating systems, use the display settings panel and select the same native mode.
- Enable VRR in the right control panel. Turn on Adaptive-Sync or the monitor’s equivalent in its on-screen menu, then enable G-SYNC or FreeSync in the GPU software when supported. If the screen flickers, test a lower maximum refresh or disable VRR temporarily to isolate the cause.
- Set a comfortable work profile. Lower brightness until white backgrounds are comfortable in your room, choose a neutral colour preset, and use operating-system scaling if text is too small. QHD gives more space, but scaling can improve readability without changing the panel’s native resolution.
- Test your real games and applications. Check a bright office document, a dark game scene and a fast camera pan. Look for reflections, unreadable shadow detail, smearing or intermittent signal loss during the return period.
Common buying and setup mistakes
- Assuming every HDMI connection reaches the advertised maximum. On the Dell, HDMI is specified at 144 Hz rather than 165 Hz. Other models can also assign different limits to different ports.
- Comparing a temporary deal as if it were a permanent price. The Dell’s $149.99 US listing was also marked temporarily out of stock. Recheck stock and delivered cost on the day you order.
- Ignoring stand ergonomics until the monitor arrives. A screen that cannot rise high enough can cause neck strain. The LG documents height, pivot and tilt; verify equivalent details for other SKUs or budget for a monitor arm.
- Treating a specification as an independent test result. Dell’s 400 cd/m², LG’s 99% typical sRGB and all refresh figures are manufacturer specifications. RTINGS’ brightness, glare, motion and smearing conclusions come from its tested samples and may not describe every revision.
- Buying the AOC solely for the HDR label. Mini LED is a real hardware distinction, but RTINGS’ dark-scene smearing warning matters if you are sensitive to trails in shadows.
- Skipping the return policy. Pixel defects, backlight variation and motion preferences are sample- and person-dependent. A clear return window is especially valuable when buying a VA gaming monitor or an unfamiliar regional suffix.
Which monitor fits which buyer?
| Your priority | Best starting point | Why | Check before purchase |
|---|---|---|---|
| One screen for office work and PC gaming | Dell G2724D | Fast IPS, high refresh, broad listed sync support, 400 cd/m² specification and stronger glare and motion results than the LG in RTINGS’ comparison | Current local price, stock, stand adjustment and DisplayPort availability |
| Adjustable work-desk ergonomics | LG 27GR75Q-B | Height, pivot and tilt are explicitly listed, with 165 Hz and 99% typical sRGB | Glare and brightness expectations, PS5 VRR requirement, exact suffix and return terms |
| HDR-focused PC gaming | AOC Q27G3XMN | Mini LED backlight and up to 180 Hz make it the most gaming-specialized option here | Dark-scene smearing tolerance, regional ports, VRR documentation and return policy |
| PlayStation 5 VRR | Dell G2724D, based on RTINGS’ reviewed model | RTINGS reports PS5 VRR support for the Dell and not for the reviewed LG | Console firmware, cable, exact monitor revision and supported resolution |
Final buying advice
For most mixed-use buyers, begin with the Dell G2724D if a current local listing is available at a competitive price and you can use DisplayPort for 165 Hz. Select the LG 27GR75Q-B instead when its fully adjustable stand is valuable or its local deal and return policy are better. Choose the AOC Q27G3XMN when Mini LED HDR is worth accepting the possibility of dark-scene smearing. Recheck the exact SKU, input limits, platform support, stock and return terms immediately before checkout; those details, rather than a universal ranking, determine which 27-inch QHD monitor is actually worth buying for your desk.
