Best 1440p 240Hz Monitor in 2026: 7 Top Picks Reviewed

If your search for a 1440p 240Hz monitor keeps coming back to overpriced options, the AOC Q27G41ZE is worth a look. It hits the exact spec combo this roundup is built around: a 27-inch QHD IPS panel running at 240Hz, without the premium markup that usually comes attached. The 0.3ms MPRT response time keeps motion clean in fast games, and G-Sync compatibility plus Adaptive-Sync handle tearing across a wide range of graphics cards. QHD on a 27-inch IPS panel also means you get noticeably better text clarity and color accuracy than a 1080p screen, which matters if this monitor doubles as a work display. The frameless design looks tidy on a desk, and the tilt-adjustable stand covers basic ergonomic needs. For anyone assembling a shortlist of 1440p 240Hz monitors and weighing value against features, this one earns its spot on practical grounds rather than flashy extras.

Features: Blue Light Filter, Flicker-Free, Shadow Control, Game Mode presets, graphical OSD menu

Warranty: 3-year manufacturer coverage

Buy this if you want a 1440p 240Hz IPS panel without paying for extras you won't use, and you're comfortable with a basic stand and no built-in speakers. Skip it if you need height and swivel adjustment out of the box, or if edge-of-screen brightness uniformity is a dealbreaker for your work. It's a solid pick for gamers prioritizing speed and clarity over design flourishes.

A monitor earns a place in a 1440p 240Hz guide by delivering the required resolution and refresh rate without making image quality an afterthought. The 27-inch Odyssey OLED G6 does that with a QHD QD-OLED panel, 240Hz refresh rate, and stated 0.03ms response time. This gives it a specification set focused squarely on rapid gaming, while its 1,000,000:1 contrast ratio and HDR10 support give the image side equal weight. Samsung lists a matte Glare Free finish, making this version especially relevant for setups where reflections are a consideration. Its QD-OLED screen has a 178-degree viewing angle, 400 cd brightness, 0.23 pixel pitch, and 99% color gamut. The display is Pantone validated for more than 2,100 colors, extending its appeal beyond games to color-sensitive creative work. Height, tilt, and swivel adjustments provide stand flexibility, while OLED Safeguard with thermal modulation is included to help prevent burn-in. The single HDMI input is the main connection constraint, but for someone shopping specifically for QHD at 240Hz, the panel, motion, contrast, and ergonomic package make the G6 a compelling candidate.

Display Technology: QD-OLED panel with 27-inch screen, 2560 x 1440 (QHD) native resolution, 16:9 aspect ratio, and 178-degree viewing angles. Contrast ratio reaches an exceptional 1,000,000:1 with zero pixel light bleed characteristic of OLED technology.

Refresh Rate and Response Time: 240Hz refresh rate paired with 0.03ms gray-to-gray response time eliminates motion artifacts and screen tearing when combined with AMD FreeSync Premium support. This combination creates buttery-smooth visuals in fast-paced competitive titles.

Color and Brightness: 400 cd/m2 brightness delivers excellent visibility even in well-lit rooms. Pantone-validated color accuracy reproduces the full 110+ skin tone shades and 2,100+ lifelike colors. HDR10 support provides enhanced dynamic range with brighter highlights and nuanced shadow detail.

Thermal Management: OLED Safeguard technology includes automatic thermal modulation and brightness adjustment to prevent burn-in while maintaining performance. Logo and taskbar dimming features activate automatically during idle periods to reduce static image retention risk.

Buy Samsung's Odyssey OLED G6 if you want a 27-inch 1440p, 240Hz QD-OLED monitor with a matte Glare Free finish, 0.03ms response time, and strong listed contrast. It is also a sensible match for users who need height, tilt, and swivel adjustment or value Pantone validation and HDR10 alongside gaming specifications. Skip it if your setup needs more than one HDMI connection without adapters, or if you specifically prefer a glossy display surface. Those buyers should look at a model with connectivity or finish better aligned to their setup.

The KTC H27E6S is a 27-inch 2K gaming monitor designed for competitive gamers and content creators seeking high refresh rates without breaking the bank. Its 240Hz native refresh rate, overclockable to 275Hz, positions it squarely in the performance gaming space while maintaining the 2560x1440 resolution that creative professionals demand.

The standout feature is the combination of Fast IPS panel technology with those high refresh rates. Most 240Hz+ monitors use TN panels, which sacrifice color accuracy. Here you get 123% sRGB color gamut and HDR400 support alongside the speed, making it genuinely versatile. The 1ms MPRT response time and Adaptive Sync eliminate ghosting during fast-paced shooters and racing games, while the wide viewing angles and color accuracy serve photo editing and design work equally well.

Build quality is solid. The white matte finish looks modern and integrates well with contemporary setups, though it requires regular wiping. The stand offers exceptional adjustability including height, tilt, swivel, and full 90-degree pivot for portrait mode. Four video inputs (dual HDMI 2.0 and dual DisplayPort 1.4) make multi-device switching hassle-free, and built-in speakers plus a 3.5mm jack handle audio without clutter.

The main limitation is that the 275Hz overclock requires manual tuning and stable performance depends on your graphics card and driver support. Additionally, the single USB 2.0 port won't satisfy users needing a full hub. The white finish, while attractive, demands more maintenance than black alternatives.

The KTC H27E6S delivers genuine gaming performance and creative-grade color at a competitive price. It's best suited for gamers who play fast-paced titles and occasionally work with media, or creators who want gaming-capable hardware without compromise. With its 3-year warranty and strong reviews, it's a reliable choice for a high-refresh, high-resolution desk.

Choosing a 1440p 240Hz monitor is largely about balancing speed with a panel that makes the resolution worthwhile, and the MSI MAG 274QP QD-OLED X24 addresses both points. Its 27-inch, 16:9 Quantum Dot OLED screen runs at 2560 x 1440 and 240Hz, while the listed 0.03ms response time and Adaptive-Sync support put fast, fluid motion at the center of its specification. That is the essential combination for this roundup's target category. The display credentials add another reason to consider it over a conventional panel. MSI lists a 1,500,000:1 contrast ratio, HDR picture-quality enhancement, Quantum Dot technology, and a 178-degree viewing angle. A glossy screen finish is part of the design, as are HDMI 2.1 and DisplayPort 1.4a inputs. The stand offers height and tilt adjustment, which helps when positioning a 27-inch screen. With WQHD resolution, OLED display technology, and the required 240Hz refresh rate all explicitly present, this is a direct fit for buyers prioritizing the article's 1440p high-refresh brief.

Buy the MAG 274QP QD-OLED X24 if your priority is a 27-inch 2560 x 1440 monitor with a 240Hz refresh rate, 0.03ms response time, and Quantum Dot OLED display technology. It also suits shoppers who value Adaptive-Sync, HDR, HDMI 2.1, DisplayPort 1.4a, and an adjustable height and tilt stand in the same model. Skip it if a matte screen is non-negotiable, since this monitor has a glossy finish, or if you want a screen larger than 27 inches or a format other than 16:9.

For shoppers who want a 1440p 240Hz monitor but are open to more screen real estate, the Sansui 34-inch curved model reframes the question entirely. Instead of a standard 27-inch QHD panel, this is a 3440x1440 ultrawide running at the same 240Hz refresh rate, giving you the resolution density this roundup targets stretched across a 21:9 curve. The VA panel brings a 3000:1 contrast ratio, well above typical IPS competitors in this category, along with 450 cd brightness and HDR400 support for punchier highlights. AI PQ visual enhancement and Adaptive Sync round out the gaming-focused feature set. The 131% color gamut coverage suggests vivid, saturated output for both games and media. If part of your criteria for the best 1440p 240Hz monitor includes immersion and multitasking space rather than a strict 16:9 frame, this curved ultrawide is a legitimate alternative worth weighing against the standard-format picks in this list.

Display: 34 inches, curved, 21:9 ultrawide aspect ratio, VA LED panel, matte finish, 3440x1440 native resolution

Performance: 240Hz refresh rate, 1ms MRPT response time, 3000:1 contrast ratio, 450 cd/m2 brightness, HDR400 support

Physical Dimensions: 31.77 inches wide, 7.48 inches deep, 17.91 inches tall

Warranty: 1-year manufacturer warranty, 30-day money-back guarantee, lifetime technical support

Buy this if you want the 240Hz smoothness this roundup is about but prefer a wider, curved canvas for immersion and multitasking. Skip it if you specifically need a standard 16:9 QHD panel, or if you're set on IPS viewing angles rather than VA. It suits gamers and multitaskers who value screen real estate over panel type.

The LG 27GR83Q-B checks every core box for a 1440p 240Hz monitor while adding headroom most budget options skip. It's a 27-inch IPS QHD panel at 240Hz with a 1ms response time, so the fundamentals this roundup is built around are all present. What sets it apart here is the extras layered on top: HDMI 2.1 for next-gen console or GPU compatibility, DisplayHDR 400 certification, and 95% DCI-P3 color coverage that makes it genuinely useful for creative work or HDR content, not just competitive play. The fully adjustable stand with height, tilt, and pivot gives it an ergonomic edge over monitors that only tilt, and the 4-pole headphone jack with DTS Headphone:X is a thoughtful touch for gamers using headsets. If you're comparing 1440p 240Hz monitors and want one that also holds up for color-sensitive tasks and future-proof connectivity, this is one of the stronger all-rounders on the list, provided you're comfortable inspecting the unit closely on arrival.

Display: 27-inch IPS LCD, 2560x1440 (QHD), 16:9 aspect ratio, 178-degree viewing angles, 0.23mm pixel pitch

Refresh Rate & Response: 240Hz via DisplayPort or HDMI 2.1, 1ms (GtG) response time, matte screen finish

Color & HDR: 1000:1 contrast ratio, 95% DCI-P3 color gamut, VESA DisplayHDR 400, 400 cd/m2 brightness

Buy this if you want a 1440p 240Hz IPS monitor with strong color accuracy, HDR support, and a fully adjustable stand for a mixed gaming and creative setup. Skip it if quality control issues like dead pixels are a concern for you, or if you need fast, reliable warranty support. Best suited to gamers who also value display versatility beyond pure competitive play.

If you're hunting specifically for a 1440p 240Hz panel, the Nitro XV272U hits that exact spec without compromise. It's an IPS display, so you get the wide 178-degree viewing angles and 99% color gamut that TN panels at this refresh rate can't match, meaning fast motion and accurate color aren't a tradeoff here. AMD FreeSync Premium keeps the 240Hz refresh rate free of tearing and stutter, which matters more at this pixel count than on lower-res displays since the GPU load is heavier. The 27-inch size is a natural match for 1440p, giving you sharp detail without needing to scale up to 4K. A fully adjustable stand (height, tilt, swivel, pivot) and DisplayPort 1.4 plus dual HDMI 2.0 round out a setup that's easy to fit into most desks. Just run it over DisplayPort, since HDMI caps out at 144Hz. For anyone comparing 1440p 240Hz monitors on panel quality and color accuracy rather than just headline refresh rate, this one belongs on the shortlist.

Display: 27-inch QHD IPS, 2560 x 1440 resolution, 16:9 aspect ratio, 0.233mm pixel pitch

Performance: 240Hz refresh rate (DisplayPort), 144Hz (HDMI), 1ms response time (0.5ms GtG), 1000:1 contrast ratio, 400 nits brightness

Power and Warranty: 26W power consumption, 3-year manufacturer warranty covering parts and labor

Buy this if you want a 1440p 240Hz IPS panel with strong color accuracy for both gaming and creative work, and you have a GPU that can push that resolution at high frame rates. Skip it if you're on HDMI-only hardware, since you'll be capped at 144Hz, or if you're sensitive to backlight bleed, a known IPS weakness that shows up in some units.
