Best 27-Inch 240Hz OLED Gaming Monitors Compared

The LG 27GS95QE and Asus ROG Swift PG27AQDM sit in the sweet spot for competitive PC gaming: a 27-inch OLED panel, 2560×1440 resolution and a 240Hz refresh rate. Both deliver exceptional response times, deep blacks and superb motion clarity, but they approach brightness, connectivity, ergonomics and long-term ownership slightly differently.

For Australian gamers building a new system or upgrading from a 144Hz IPS display, the decision is less about basic image quality and more about priorities. The LG is the newer, more feature-rich option with a strong focus on console compatibility and practical usability, while the Asus remains a compelling choice when discounted and properly updated with the latest firmware.

What Separates These OLED Gaming Monitors

Both screens use a 26.5-inch OLED panel marketed as 27 inches, with a 16:9 aspect ratio and 2560×1440 resolution. That combination provides a noticeably sharper image than 1080p without demanding the same graphics card power as 4K. It is a particularly sensible match for GPUs such as the Radeon RX 7800 XT, GeForce RTX 4070 Super and faster models.

The key specifications are closely matched. Each monitor reaches 240Hz, supports adaptive sync, offers a quoted 0.03ms grey-to-grey response time and carries DisplayHDR True Black 400 certification. OLED pixels switch individually, so dark scenes have effectively perfect black levels and there is no conventional LCD backlight bleed around bright objects.

The biggest practical difference is generation. The Asus launched earlier and established the 27-inch 1440p 240Hz OLED category, while the LG 27GS95QE arrived with refinements aimed at brightness management, connectivity and everyday gaming use. Neither is automatically the right purchase at every price, so Australian sale pricing matters.

OLED Image Quality And HDR

In games such as Cyberpunk 2077, Alan Wake 2 and Resident Evil 4, both monitors produce a dramatic contrast advantage over IPS and VA alternatives. Shadows look genuinely dark, bright UI elements remain crisp and colours appear rich without the grey haze common on LCD panels in a dim room. Their wide-gamut coverage also gives modern games a vivid, cinematic appearance.

HDR performance is impressive in a dark or moderately lit room, although the True Black 400 rating should be understood correctly. OLED screens can show small bright highlights very effectively, but their full-screen brightness is limited compared with a high-end Mini-LED monitor. A white webpage or bright snow scene will not remain as intense across the entire panel.

The LG has an advantage for users who dislike glossy reflections because its anti-glare coating is more forgiving near windows and ceiling lights. The Asus can look especially clean and punchy in controlled lighting, but reflections may be more noticeable depending on desk placement. Neither display replaces a strong Mini-LED model for bright-room HDR impact.

OLED text clarity is another consideration. The subpixel layout can produce subtle colour fringing around small fonts, especially on white text against a dark background. It is usually far less distracting in games than on a desktop, but anyone spending all day in spreadsheets, browser tabs or code editors should inspect both displays in person where possible.

240Hz Gaming Performance

The main reason to choose either monitor is motion performance. At 240Hz, each refresh takes approximately 4.17 milliseconds, and the OLED response is fast enough to keep up with that refresh rate. Fast camera movements in Counter-Strike 2, Valorant, Apex Legends and Overwatch 2 look exceptionally clear when the graphics card can produce high frame rates.

OLED also avoids the dark-level smearing seen on many VA gaming monitors. Character silhouettes remain clean during rapid movement, while low input latency makes mouse control feel immediate. The improvement over 144Hz is most apparent in competitive shooters and racing games, though the difference is still visible when navigating ordinary games at high frame rates.

Adaptive-sync support helps prevent tearing when frame rates fluctuate. The exact experience depends on the graphics card and connection, so enable the monitor’s variable refresh setting and the appropriate FreeSync or G-SYNC-compatible option in the driver. A Radeon and a GeForce card can both work well, but users should check current driver behaviour after installation.

A 240Hz panel does not guarantee 240 frames per second. New releases at 1440p may need upscaling, reduced ray tracing or carefully selected settings to reach that level. For esports titles, mid-to-high-end current GPUs are much more likely to take advantage of the refresh rate; for single-player games, the OLED contrast and response speed remain valuable even at lower frame rates.

Design, Ergonomics And Connectivity

The LG includes a more versatile stand with height, tilt, swivel and pivot adjustment, making it easier to position for a long gaming session or a portrait-oriented secondary setup. It also has a relatively practical rear layout and a USB hub, which can reduce cable clutter around a keyboard and mouse.

The Asus uses an attractive ROG design with strong build quality and a compact stand footprint. Its cooling approach and heatsink help manage the OLED panel during extended use, while the on-screen display offers detailed gaming controls. Desk space is still worth measuring, as the angular stand can occupy more room than a simple monitor arm.

Connectivity is an important point of difference. The LG provides HDMI 2.1 inputs, DisplayPort 1.4 with Display Stream Compression and USB connectivity, giving it better flexibility for a gaming PC and current consoles. The Asus uses DisplayPort 1.4 and HDMI 2.0. Its HDMI inputs can still support high-refresh 1440p gaming according to the monitor’s specifications, but the LG is the safer long-term choice for mixed PC and console ownership.

Neither model should be selected for built-in audio. Headset users will get better results from a dedicated DAC, motherboard audio or wireless headset receiver, while console players should check how audio is routed through HDMI and the console’s settings. A monitor arm can improve both models, but confirm VESA compatibility and leave room for the rear cables.

Burn-In Protection And Daily Use

OLED ownership requires a little more awareness than using an ordinary IPS screen. Static elements such as a Windows taskbar, browser controls, game HUDs and fixed news tickers can contribute to image retention over long periods. Permanent burn-in is not guaranteed to occur, but the risk increases with repeated, unchanging content and high brightness.

Both monitors include protection features such as pixel shifting, screen refresh routines, logo brightness controls and automatic dimming. Keep these enabled. The LG also provides OLED care settings through its menu, while Asus offers its own panel protection system and firmware-based refinements. Do not interrupt a required panel refresh simply because the screen appears ready to turn off.

For a mixed-use desk, set the screen to sleep quickly, use a dark desktop theme and allow the monitor to run its maintenance cycle. Reducing brightness for office work is sensible, particularly in a dim room. These habits are easy to adopt and help make a 240Hz OLED more suitable as a daily monitor rather than a screen reserved for gaming nights.

Warranty terms deserve close attention in Australia. OLED burn-in coverage can vary by model, retailer and the exact written policy, so do not rely only on a sales listing. Keep the receipt, record the serial number and check the manufacturer’s Australian warranty conditions before buying. Australian Consumer Law may provide additional remedies when a product is faulty or fails to meet acceptable quality, but it does not remove the need to follow reasonable care instructions.

LG 27GS95QE Versus Asus PG27AQDM

The LG is the stronger all-round choice for most new buyers. Its newer design, HDMI 2.1 support, useful stand adjustment, anti-glare finish and practical OLED care features make it easier to recommend for a gaming PC that may later share time with a PlayStation 5 or Xbox Series X. The combination of excellent motion handling and deep contrast also suits both esports and cinematic single-player titles.

The Asus remains attractive when its price is clearly lower. It offers the same core resolution, refresh rate and OLED contrast, and its ROG styling may appeal to buyers who prefer a more aggressive gaming aesthetic. Updated firmware is important, particularly for brightness behaviour and panel management, so check the installed version and available updates rather than assuming an older unit is fully optimised.

In a bright Sydney apartment, a Melbourne home office near a large window or an Adelaide gaming room with strong daytime light, the LG’s anti-glare treatment may be more forgiving. In a controlled room used mostly at night, the visual difference between the two becomes smaller. Buyers who use a desktop for many hours should also consider whether OLED’s text rendering is acceptable before committing.

Value can change quickly during Australian retail promotions. Compare authorised retailer pricing, delivery costs and return policies across major electronics chains, specialist PC stores and online marketplaces. A substantial discount on the Asus can make it the better deal, but a small price gap generally favours the LG’s broader feature set and newer platform.

Choosing The Right Monitor For Your Setup

The most suitable display depends on the way the computer is used, the GPU installed and how much daylight reaches the desk. Use the following checks before placing an order:

Both monitors are excellent upgrades from a 60Hz or 144Hz LCD, but they are not identical purchases. The LG is the safer recommendation for a flexible modern setup, while the Asus makes financial sense when a retailer offers a strong clearance or promotional price and the buyer is comfortable with its older HDMI implementation.

For Australian PC builders, the final decision should include the total delivered cost in Australian dollars, GST-inclusive pricing and the support offered by the seller. A good monitor can remain on a desk for many years, so a modest saving is less valuable than dependable warranty assistance, suitable connectivity and a panel that fits the room.

Choose the LG 27GS95QE for the most complete feature set, or take the Asus ROG Swift PG27AQDM when its discount makes the same core OLED gaming experience substantially better value. Check current Australian stock, firmware status and warranty terms before buying, then pair the display with a GPU capable of making the most of 240Hz.
