Choosing the best 240hz 1440p monitors comes down to balancing panel technology against your primary gaming genres. Modern 2560×1440 displays hit a performance sweet spot, providing sharper pixel density than standard 1080p screens without demanding the raw graphical horsepower of a 4K panel. At 240Hz, motion clarity improves noticeably during fast-paced competitive shooters, provided your graphics card can drive high framerates at this resolution.
While standard IPS monitors prioritize reliable brightness and zero burn-in risk at accessible costs, modern OLED panels provide unmatched response times and infinite contrast ratios. If you are also weighing wider aspect ratios, you might explore our guide to the best ultrawide monitors to see how standard 16:9 displays compare against 21:9 alternatives.

Detailed Product Breakdown
Acer Nitro XV272U W2bmiiprx
The MONITOR Acer Nitro 27in QHD 2560×1440 IPS 240Hz is an entry-level option built around an IPS panel. It features a 2560×1440 resolution, 1ms standard response time, and AMD FreeSync Premium support. The fully adjustable stand offers 4.7 inches of height adjustment, 360-degree swivel, and 90-degree pivot options for ergonomic placement.
One critical port limitation involves its input standards. The display achieves its full 240Hz refresh rate exclusively through the DisplayPort 1.4 connection, while the two HDMI 2.0 ports cap at 144Hz. This model suits PC desktop players on a budget who connect through DisplayPort, but console users or multi-device setups will encounter refresh rate limits over HDMI.
ASUS ROG Strix XG27ACMG
The ASUS ROG XG27ACMG 27 Inch 1440p 270Hz USB-C G-SYNC expands past standard 240Hz limits with a factory overclock reaching up to 270Hz. Its Fast IPS panel covers 95 percent of the DCI-P3 color space, ensuring smooth color gradation for mixed gaming and creative work. The monitor includes ASUS Extreme Low Motion Blur Sync, which enables backlight strobing alongside variable refresh rate technologies.
Connectivity is a key strength due to a built-in USB Type-C port that supports DisplayPort Alternate Mode. This port lets laptop users route video over a single cable to reduce desk clutter. However, backlight strobing technologies can reduce perceived panel brightness during operation, which users in sunlit rooms should keep in mind.
Samsung Odyssey OLED G6 (G61SH)
The Samsung 27″ Odyssey OLED G6 (G61SH) QD-OLED employs a Quantum Dot OLED panel with an ultra-low 0.03ms gray-to-gray response time. Because each pixel generates its own illumination, the screen delivers true black levels alongside vibrant color output. The screen surface features Glare Free matte coating technology to suppress reflections from nearby lamps and windows.
Samsung includes OLED Safeguard, an integrated thermal modulation system intended to minimize image retention risks over long operating hours. While QD-OLED panels offer superior motion handling for fast shooters, potential pixel wear remains an operational factor for users displaying static desktop software all day.
SANSUI 34-Inch Curved UWQHD Monitor
The SANSUI 34 Inch Curved Monitor 240Hz UWQHD departs from standard 16:9 formats by utilizing a 34-inch curved ultrawide 21:9 layout at 3440×1440. Built with a Fast VA panel, it offers higher native contrast than typical IPS screens. Dual HDMI 2.1 ports and dual DisplayPort 1.4 connections each handle up to 240Hz natively.
The ultrawide form factor provides significant extra horizontal space for immersive simulation games or side-by-side multitasking windows. Buyers should note that driving 3440×1440 at 240Hz requires roughly 34 percent more graphics rendering power than a standard 2560×1440 display, requiring a stout GPU.
LG UltraGear 27GX704A-B
The LG 27GX704A-B 27-inch Ultragear QHD (2650×1440) delivers a 240Hz refresh rate and a 0.03ms response time on a glossy OLED panel. Certified for VESA DisplayHDR True Black 400 and covering 98.5 percent of the DCI-P3 color gamut, it provides intense contrast with peak brightness up to 1300 nits in small HDR highlights. It supports both NVIDIA G-Sync Compatible and AMD FreeSync Premium Pro modes.
Equipped with dual HDMI 2.1 inputs, DisplayPort 1.4, and a USB 3.2 hub, this unit provides straightforward compatibility across modern PCs and current-generation consoles. Because the panel finish is glossy, ambient lighting and unshaded windows behind the user can cause noticeable surface reflections during dark gameplay sequences.

Buying Considerations for 240Hz 1440p Displays
To learn more about general 1440p panel selection, check out our guide to the best 1440p gaming monitors for broader context. When moving up to the 240Hz tier specifically, several technical elements dictate actual in-game performance.
IPS panels remain the most balanced choice for daytime environments, sustained static desktop use, and general productivity. They suffer no burn-in risks and maintain stable color accuracy across wide viewing angles. However, IPS monitors feature limited contrast ratios, meaning dark game scenes can appear gray in unlit rooms.
OLED and QD-OLED options eliminate motion blur almost completely due to their 0.03ms pixel response times, making targets easier to track during fast camera pans. The trade-off centers on panel care routines and ambient light management. Matte coatings handle reflections well, while glossy finishes offer cleaner perceived contrast at the cost of mirror-like reflections in bright rooms.
Display connection standards also impact your real-world refresh rates. As seen on older HDMI 2.0 ports, bandwidth limits can cap 1440p output to 144Hz. Make sure your desktop GPU provides an open DisplayPort 1.4 or HDMI 2.1 port to realize the full 240Hz capability of the screen.
Frequently Asked Questions
Can HDMI cables output 1440p at 240Hz?
Standard HDMI 2.0 lacks the bandwidth for uncompressed 1440p at 240Hz and generally caps at 144Hz. You need a monitor and graphics card equipped with HDMI 2.1 to achieve 240Hz at 1440p over an HDMI cable. Otherwise, you must use a DisplayPort 1.4 connection.
What GPU power is required for 240Hz at 1440p?
Demanding modern games will not reach 240 frames per second without high-end graphics hardware and adjusted visual settings. Competitive titles like esports shooters are far easier to drive at 240 FPS on midrange graphics cards than visually heavy action games.
Final Verdict: Which 240Hz 1440p Monitor Fits Your Desk?
If you want top-tier motion clarity and deep contrast for gaming in dimmer environments, the LG 27GX704A-B and Samsung Odyssey OLED G6 stand out through their 0.03ms response times. For practical desk setups that combine office productivity with high-refresh competitive gaming, the ASUS ROG XG27ACMG offers versatile USB-C connectivity and strong Fast IPS performance without burn-in maintenance. Budget-conscious players using DisplayPort will find straightforward high-speed value in the Acer Nitro XV272U.
