For US buyers seeking a 1440p IPS monitor, the best fit depends on whether you value price, a very high refresh rate, or esports-focused features. The Dell Alienware AW2725DM is a sensible gaming pick if 180 Hz is enough; LG’s 27G640A-B raises the ceiling to 300 Hz; and ASUS’s ROG Swift PG27AQN goes up to 360 Hz. These are use-case picks, not a claim that IPS beats OLED or VA for every buyer.
What a 1440p IPS monitor offers
1440p means a resolution of 2560 × 1440 pixels. It provides more image detail than 1080p without the higher processing demands associated with 4K. In RTINGS’ 2026 US roundup, 27 inches is described as the most common size for a 1440p display, though the right size depends on your desk and viewing distance. RTINGS’ 1440p monitor guide says its recommendations consider review performance, visitor feedback, price, and availability, and its page reports that it has bought and tested more than 405 monitors.

This guide narrows the choice to IPS models. That is useful if viewing angles and image consistency matter to you, but it is not a universal panel recommendation: broader 1440p roundups also include OLED and VA options. IPS also does not guarantee strong contrast or dark-room HDR.
Top 1440p IPS picks by use case
| Monitor | Best suited to | Published resolution and refresh rate | What to know |
|---|---|---|---|
| Dell Alienware AW2725DM | Gaming where 180 Hz is sufficient | 27-inch, 2560 × 1440, 180 Hz (RTINGS) | RTINGS reports good motion handling and wide viewing angles, but weak contrast and HDR performance. |
| LG UltraGear 27G640A-B | High-refresh gaming and mixed use | 27-inch QHD IPS, 300 Hz (LG) | LG lists FreeSync Premium and G-Sync compatibility, plus an adjustable stand. Its response-time and color figures are manufacturer specifications, not independent test results cited here. |
| ASUS ROG Swift PG27AQN | Esports and high-frame-rate FPS gaming | 2560 × 1440, up to 360 Hz (ASUS) | ASUS lists G-SYNC, ULMB 2, and NVIDIA Reflex Analyzer. The published features do not by themselves establish comparative real-world performance. |
Dell Alienware AW2725DM: a measured 180 Hz gaming option
RTINGS lists the 27-inch AW2725DM as a 2560 × 1440 IPS monitor with a maximum 180 Hz refresh rate. Its review describes good motion handling and wide viewing angles, but finds that blacks look gray and HDR performance is weak. RTINGS recommends gaming outside HDR on this model. Those are findings from RTINGS’ review, not tests conducted for this article. See RTINGS’ 1440p gaming monitor recommendations.

LG UltraGear 27G640A-B: 300 Hz with useful ergonomics
LG’s US specification page lists a 27-inch QHD IPS panel with a 300 Hz refresh rate, up to 95% DCI-P3 color, VESA DisplayHDR 400, FreeSync Premium, G-Sync compatibility, and built-in speakers. The stand supports height, tilt, swivel, and pivot adjustments. LG also advertises a 1 ms response time; treat that as a manufacturer claim rather than an independently verified result. A DisplayHDR 400 label alone does not establish strong dark-room HDR contrast. Check LG’s product specifications for the exact model you are considering.
ASUS ROG Swift PG27AQN: the highest listed refresh rate
ASUS specifies a QHD (2560 × 1440) Ultrafast IPS panel with refresh rates up to 360 Hz. Its US product page lists NVIDIA G-SYNC, ULMB 2, and NVIDIA Reflex Analyzer and positions the monitor for esports and fast-paced FPS games. These are ASUS’s published specifications and positioning, not independent test findings. Verify the features and ports on the exact regional model before buying. See ASUS ROG’s PG27AQN page.

How to choose between them
Match refresh rate to the games and PC
A monitor’s maximum refresh rate is most useful when your PC can deliver frame rates that take advantage of it. The options here step from 180 Hz to 300 Hz to 360 Hz; paying for the highest figure makes little sense if your games and hardware rarely approach it. For competitive play, also consider motion handling and adaptive-sync support rather than relying on refresh rate alone.
Separate HDR labeling from actual contrast
HDR performance depends on more than a certification badge. Consider brightness, local dimming, and contrast, especially if you play in a dark room. RTINGS’ AW2725DM review is a practical warning: it reports weak HDR and contrast despite the monitor’s otherwise useful gaming characteristics. The cited product specifications do not provide independent comparative HDR test results for the LG or ASUS models.
Rank #3
- High-Resolution QHD Gaming Display: 27-inch QHD (2560 x 1440) gaming monitor with 180Hz refresh rate designed for professional gamers and immersive gameplay
- ASUS Extreme Low Motion Blur Sync Technology: ELMB Sync technology enables ELMB and variable-refresh-rate technologies to work simultaneously to eliminate ghosting and tearing for sharp gaming visuals with high frame rates

- High Dynamic Range Support: HDR technology supports HDR-10 format to enhance bright and dark areas for improved visual depth and contrast
- Package Contents: DisplayPort cable, L-shaped Screwdriver, Power cord, Power adapter, Quick start guide, Warranty Card
Check comfort, ports, and purchase terms
- Viewing setup: IPS viewing angles may help when several people watch the screen, but consult a review of the exact model for image consistency.
- Stand: LG lists height, tilt, swivel, and pivot adjustments for the 27G640A-B. Confirm the stand features of the alternatives if ergonomic positioning matters.
- Connectivity: Check the exact regional SKU’s ports, including whether it meets any USB-C or laptop-docking needs. The cited specifications do not establish a common port configuration across all three.
- Price and availability: Compare live prices, warranty coverage, return terms, and stock with retailers in your region. Prices and promotions change, and the cited sources do not establish a current price comparison.
- Region: RTINGS’ recommendations target products available in the United States. Outside the US, confirm the local model number and specifications rather than assuming every feature carries over.
Which one should you choose?
Choose the Dell if you want a 27-inch 1440p IPS gaming monitor and 180 Hz is adequate, while accepting RTINGS’ warnings about HDR and contrast. Consider the LG if you can use a 300 Hz refresh rate and value its listed stand adjustments and adaptive-sync support. Choose the ASUS only if its 360 Hz ceiling and esports-oriented features fit your setup and priorities. Compare the live price and exact SKU before deciding; the available evidence does not establish a current least-expensive or best-value winner.
