Our Picks at a Glance
How To Choose The Best 240Hz OLED Monitor
Picking your first OLED gaming monitor involves a few key decisions. The most important are the panel type (WOLED vs QD-OLED), the resolution that matches your graphics card, and the physical size that fits your desk. Here is what each choice really means for your gaming experience.
Panel Type: WOLED vs. QD-OLED
WOLED (White OLED) panels, like the ones LG uses, produce colors by passing white light through color filters. This typically gives you truer blacks in a bright room and a matte finish that cuts down reflections. QD-OLED (Quantum Dot OLED) panels, from Samsung and MSI, use blue OLEDs with quantum dots to create a wider color gamut and often a glossy finish that makes colors look punchier. In a dark room, QD-OLEDs usually pop more, but they can show a slight purple tint to blacks in direct sunlight.
Resolution Balancing
1440p (QHD) is the balance for hitting a full 240Hz without needing the most expensive graphics card on the market. 4K (UHD) at 240Hz is incredibly demanding and requires a top-tier GPU like an RTX 4090 to push that many frames in modern titles. However, a 4K OLED at 240Hz gives you the sharpest desktop experience and incredible image clarity when gaming.

In‑Depth Reviews
1. ASUS ROG Strix 27” 1440P OLED Gaming Monitor (XG27AQDMG)
Our pick — over 4★ from 750+ verified ratings; the strongest balance of quality and price.
A glossy 26.5-inch WOLED that makes colors pop like a premium TV on your desk.
This ASUS ROG Strix uses a third-generation glossy WOLED panel at 2560×1440 with a 240Hz refresh rate and a 0.03ms response time. The glossy finish eliminates the hazy look of matte coatings, making the 99% DCI-P3 color gamut look punchier and more vibrant in a controlled lighting environment. It also includes ASUS OLED Anti-flicker technology and a custom heatsink to help prevent burn-in, backed by a 3-year warranty with burn-in coverage.
Shoppers say that the picture quality is a “crazy difference” compared to their old 165Hz IPS monitor, and that “the blacks and contrast in color is the best I’ve ever seen.” The monitor has an optional uniform brightness setting that keeps luminance levels consistent, which is handy for desktop work. The main drawback is that glossy screens reflect room light, so you will want to control window glare or use it in a darker room. It is a specialist choice for image-quality purists who prioritize pop over anti-glare practicality.
Compared to the matte LG 27GS93QE, the ASUS glossy WOLED looks visibly punchier in a dark room, but the LG handles bright room reflections better.
The Glossy Advantage
- Glossy WOLED delivers the punchiest, most vibrant image in a 1440p monitor
- 3-year warranty with burn-in coverage included
- Custom heatsink and anti-flicker tech reduce burn-in risk
The Catch
- Glossy screen shows reflections in a bright room
- 26.5-inch size is slightly smaller than typical 27-inch panels
Best for: gamers who play in a controlled lighting setup and want the richest possible colors and deepest blacks from a glossy OLED.
Reconsider if: your desk faces a window or you need an anti-glare screen for daytime work.
2. ASUS ROG Swift 32” 4K OLED Gaming Monitor (PG32UCDM)
The 32-inch 4K QD-OLED that balances stunning image quality with blistering speed for every genre.
You get razor-sharp 4K resolution at 240Hz with a 0.03ms response time, meaning even the fastest camera movements stay perfectly clear without ghosting. The QD-OLED panel covers 99% DCI-P3 and delivers VESA DisplayHDR 400 True Black compliance, so bright highlights and dark shadows appear in the same scene without washing out. ASUS backs this premium pick with a custom heatsink and graphene film to manage heat and reduce the risk of burn-in.
Buyers report that the glossy screen makes computing enjoyable again, with vibrant colors that make games feel rich. The main trade-off is that hitting a full 240Hz at 4K requires a very powerful graphics card. If you are building a top-tier rig and want one monitor for both serious gaming and daily use, this is the one to beat. Unlike the cheaper 1440p options, this gives you a true 3840×2160 desktop canvas that makes text and UI elements noticeably sharper.
Why It Leads
- 4K resolution at 240Hz is the highest-end gaming combo available today
- QD-OLED delivers vibrant HDR and deep, inky blacks
- Graphene film and custom heatsink for passive cooling
The Trade-Offs
- Requires a top-tier GPU (RTX 4090) to push 4K 240Hz in new titles
- Premium investment over 1440p options
Reach for this if: You want the ultimate single-monitor setup for both competitive gaming and 4K content creation without compromise.
Look elsewhere if: Your budget is tighter or your GPU cannot reliably push 4K above 120Hz.
3. Alienware AW2725DF OLED Gaming Monitor
A 360Hz refresh rate gives you a 50% motion-clarity advantage over standard 240Hz panels.
This Alienware uses a 26.7-inch QD-OLED panel at 2560×1440 resolution with a 360Hz refresh rate and a 0.03ms response time. For competitive gamers, that extra smoothness means you see and react to in-game movements faster. The QD-OLED technology delivers DCI-P3 99.3% color coverage with Delta E <2 accuracy, so visuals look true-to-life. It also meets VESA DisplayHDR True Black 400 certification, giving you deep blacks and bright highlights.
Owners mention that the deep blacks and vibrant colors make this a “god-like” monitor for gaming, praising its infinite contrast ratio and adjustable stand. One reviewer called it a “Jack of All Trades” for both competitive and casual gaming. The catch is that text clarity can look slightly less sharp than an LCD due to the QD-OLED subpixel layout, and the coating can show a slight purple tint in direct light. It also comes with a 3-year burn-in warranty for confidence.
Compared to the ASUS ROG Strix XG27AQDMG, the Alienware delivers a 360Hz refresh rate versus 240Hz, giving you the edge in fast-paced esports titles.
Speed First
- 360Hz refresh rate is a measurable advantage over 240Hz monitors
- QD-OLED color accuracy (Delta E <2) is excellent from the start
- 3-year burn-in warranty included
One Caveat
- Minor text clarity issues due to the subpixel layout
- Some customers note a purple tint to the anti-glare coating in bright rooms
Grab it for: esports enthusiasts who want the highest possible refresh rate in a 1440p QD-OLED package.
skip it if: you do a lot of text-based productivity work and need perfect font rendering.
4. MSI MPG 321URX QD-OLED
A 32-inch 4K QD-OLED that gives you premium HDR and a built-in KVM without the top-tier price.
The 31.5-inch UHD panel runs at 240Hz with a 0.03ms GtG response time, meaning you get smooth motion and crisp detail across 1.07 billion colors (10-bit). It covers 99% DCI-P3 and is VESA DisplayHDR True Black 400 certified. A big plus for multi-device users is the built-in KVM switch with PiP/PbP, and the USB Type-C port delivers up to 90W of power to a laptop — so you can run a second computer with just one cable.
Reviewers point out that switching from an IPS panel to this QD-OLED is “breathtakingly beautiful” for HDR gaming, and that the 32-inch size is a large step up from 27-inch screens. One reviewer called it “the best 4K OLED I’ve ever used.” The main downside is that Mac users sometimes face a flickering issue with dual-monitor setups that requires a specific fix (disabling DSC and locking to DisplayPort). If you want a 4K gaming powerhouse that also handles workstation duty, this is a smart pick.
Unlike the more premium ASUS PG32UCDM, the MSI offers a similar QD-OLED experience at a lower entry point while adding a sturdy KVM for mixed PC and console setups.
Why It Works
- 4K resolution with 240Hz for sharp, smooth gaming
- Built-in KVM and 90W USB-C charging for dual-device use
- OLED Care 2.0 software for burn-in prevention
Heads Up
- Mac users may need to adjust settings to fix dual-monitor flicker
- Stand is large; you may want a monitor arm for desk space
Perfect for: gamers and creators who need a sharp 4K OLED that also functions as a productivity hub with KVM and fast laptop charging.
Not for: anyone who needs an ultrawide format for racing or flight sims.
5. ROG Strix XG27AQDMES Gaming Monitor
A 27-inch QD-OLED that knows when you walk away and protects itself from burn-in.
This ASUS model uses a 26.5-inch QD-OLED panel at 2560×1440 with a 240Hz refresh rate and 0.03ms response time. Its standout feature is the Neo Proximity Sensor, which detects when you are not nearby and switches the screen to black to reduce burn-in. This works alongside ASUS OLED Care Pro, accessible through the DisplayWidget Center application, giving you mouse-based control over monitor settings — no fiddling with OSD buttons.
Buyers mention that the image is “absolutely stunning” and that “OLED makes all the difference,” especially for games like Cyberpunk. However, buyers report that it lacks a USB hub and KVM switch, which might be a dealbreaker for those who switch between a PC and a laptop. The build quality is described as excellent, with fast menus, but some find the OLED cleaning reminders too frequent. It hits a nice balance of features for gamers who want smart burn-in prevention without paying for a full premium flagship.
Unlike the Neo Proximity sensor on this model, the cheaper Pixio PX277 OLED relies only on period pixel refreshes for burn-in management.
Smart Protection
- Neo Proximity Sensor automatically helps prevent burn-in
- DisplayWidget Center for mouse-controlled settings
- QD-OLED delivers excellent color and contrast
Missing Bits
- No USB hub or KVM for multi-device setups
- Some buyers find the pixel refresh reminder too frequent
Reach for this if: You want a 1440p QD-OLED with proactive burn-in protection and easy software control.
Look elsewhere if: You need a built-in USB hub or KVM to switch between a PC and a laptop.
6. LG 27GS93QE 27-inch Ultragear OLED Gaming Monitor
A 27-inch WOLED that gives you true blacks and a matte finish at a price that makes sense for your first OLED.
This LG Ultragear uses a 27-inch WOLED panel at 2560×1440 with a 240Hz refresh rate and a 0.03ms GtG response time. It is VESA DisplayHDR True Black 400 certified, which means you get deep, rich blacks and impeccable detail in dark game scenes. The matte anti-glare finish minimizes light reflections so you can play without distractions, and it covers up to 98.5% DCI-P3 for vibrant HDR colors.
Buyers call this their “first OLED, a revelation,” noting that the colors and contrast are a massive upgrade from any non-OLED screen. One reviewer explicitly states, “this panel beats QD-OLED easily” in bright rooms because the WOLED blacks stay true black rather than turning slightly purple. The main limitation is that peak brightness is lower than some QD-OLEDs, so you will get the best HDR experience in a darker room. It also includes a 2-year warranty covering the OLED panel.
Compared to the ASUS XG27AQDMG, the LG is a better choice if your room has lots of ambient light, as the matte finish handles reflections much better than a glossy panel.
Solid Foundation
- True WOLED blacks that do not shift purple in bright rooms
- Matte finish reduces glare effectively
- 2-year warranty covering the OLED panel
The Limits
- Lower peak brightness compared to QD-OLED alternatives
- Best HDR performance requires a dimmer room
Ideal for: first-time OLED buyers who want a reliable, well-priced monitor with great blacks and a practical matte screen.
Not for: anyone who needs the absolute highest HDR peak brightness or a glossy screen.
7. Pixio 27″ WOLED Gaming Monitor (PX277 OLED Max V2)
A budget-focused 27-inch WOLED that undercuts the premium brands while keeping a 240Hz panel and USB-C charging.
The PX277 OLED Max V2 features a 27-inch WOLED panel at 2560×1440 with a 240Hz refresh rate and 0.03ms response time. It is DisplayHDR True Black 400 certified. A key feature for laptop users is the USB-C port that delivers up to 65W of power and supports 1440p at 240Hz over a single cable. It also includes a built-in KVM switch, letting you control two devices with a single keyboard and mouse.
Owners mention the monitor is a “beautiful” performer for the price, but one reviewer noted that the built-in speakers are “terrible” — tinny and with noticeable audio latency. Others mention that the included DisplayPort cable is only DP 1.2 despite the monitor supporting DP 1.4, and no HDMI cable is included. It is a straightforward, no-frills OLED that saves you money by leaving out premium extras while delivering the core 240Hz WOLED experience.
Unlike the LG 27GS93QE, the Pixio adds a USB-C port with 65W charging for laptop users, making it a more versatile budget option for mixed setups.
Budget Edge
- USB-C port with 65W charging and display support
- Built-in KVM for switching between two devices
- WOLED panel with 240Hz at a lower entry point
Cut Corners
- Built-in speakers are very poor quality
- Includes a DP 1.2 cable instead of the advertised DP 1.4
Grab it for: a budget gaming OLED where you want laptop charging, a KVM, and do not need premium extras.
pass on it if: you rely on built-in speakers or want a premium unboxing experience with the right cables.
8. Samsung 27” Odyssey OLED G6 (G60SD)
A 27-inch QD-OLED with a 360Hz refresh rate and a dynamic cooling system that fights burn-in.
The Samsung Odyssey OLED G6 packs a 27-inch QD-OLED panel at 2560×1440 with a 360Hz refresh rate and a 0.03ms response time. It uses a Pulsating Heat Pipe Dynamic Cooling System — a first for monitors — that evaporates and condenses coolant to dissipate heat 5x better than older graphite sheets. Samsung also includes a Thermal Modulation System that predicts surface temperature and adjusts brightness automatically to reduce heat and prevent burn-in.
Buyers call this a “360Hz OLED beast” and report that the improved fluidity in competitive games like COD and Apex was a bigger upgrade than their PC components. The monitor also features Samsung’s Glare Free technology, which significantly cuts down reflections. The major downside, noted in reviews, is that the monitor only includes an HDMI 2.0 port (not the advertised HDMI 2.1), requiring DisplayPort with DSC to hit 360Hz. This can cause a brief black screen when alt-tabbing.
Compared to the Alienware AW2725DF, the Samsung G60SD offers a similar 360Hz speed but adds a unique active cooling system for burn-in prevention. However, the Alienware includes DisplayPort 1.4 from the start without the HDMI confusion.
Speed & Cooling
- 360Hz refresh rate with QD-OLED color and contrast
- Dynamic Cooling System with heat pipe for burn-in protection
- Glare Free coating reduces reflections
The Catch
- Samsung includes HDMI 2.0, not HDMI 2.1 as some expected

Look elsewhere if: you need full HDMI 2.1 bandwidth or are sensitive to DSC-related black screens.
9. LG 34GS95QE 34-inch Ultragear OLED Curved Gaming Monitor
A 34-inch ultrawide WOLED that wraps around your field of view with an aggressive 800R curve.
This LG Ultragear uses a 34-inch WOLED panel with a 21:9 aspect ratio, a steep 800R curve, and a 3440×1440 resolution running at 240Hz with a 0.03ms response time. The curve draws the game into your peripheral vision, making you feel more surrounded by the action than a flat screen can. It is VESA DisplayHDR True Black 400 certified with a 1.5M:1 contrast ratio, so dark scenes retain impeccable detail with deep, true black levels.
Buyers describe the blacks as so true that “the first time my desktop loaded, I thought the monitor was off.” The 240Hz motion clarity is noticeably sharper than lower refresh rates, and the anti-glare coating keeps reflections minimal. A few reviewers mention that text clarity is a weakness of the OLED subpixel layout, and the 800R curve is very aggressive, which can be distracting for desktop productivity but fantastic for FPS gaming.
Unlike the flat ASUS PG32UCDM, the LG 34GS95QE offers a much wider 21:9 field of view, but the text clarity is less sharp for productivity tasks compared to a high-PPI 4K monitor.
Wrap-Around View
- 34-inch ultrawide with 800R curve for deep immersion
- True WOLED blacks with 1.5M:1 contrast ratio
- 240Hz with 0.03ms response for smooth motion
Trade-Offs
- Aggressive curve can be distracting for productivity work
- OLED text clarity is less sharp than a similar IPS panel
Ideal for: rich single-player and FPS gaming where you want the widest field of view and deepest curve.

This MSI monitor uses a 34-inch UWQHD (3440×1440) QD-OLED panel with a 240Hz refresh rate and a 0.03ms response time. It features a graphene film and custom heatsink for efficient fanless heat dissipation, which means zero fan noise during use. The USB Type-C port delivers up to 98W of power delivery, so you can drive and charge a high-end laptop from a single cable. It also supports 1.07 billion colors (10-bit) with 99.3% DCI-P3 and Delta E ≤2 color accuracy.
Buyers call the image “gaming heaven” and say the QD-OLED colors and contrast are stunning, especially for racing and flight sims on the 21:9 aspect ratio. The built-in KVM is listed as reliable for hybrid work-play setups. One downside is that the large 34-inch size requires a deep desk or a monitor arm. Another is the OLED burn-in fear — though customers note that MSI’s OLED Care 2.0 and the 3-year burn-in warranty make it a safe bet.
Compared to the LG 34GS95QE, the MSI uses a QD-OLED panel that delivers more vibrant colors, but the LG’s WOLED blacks stay truer in a bright room thanks to the matte finish.
Hybrid Hero
- Silent fanless heatsink with graphene film for cooling
- 98W USB-C charging for powerful laptops
- QD-OLED with 99.3% DCI-P3 for stunning HDR
Space Needed
- Large 34-inch size requires a deep desk or monitor arm

Best for: users who want a silent, versatile ultrawide QD-OLED that charges their laptop and handles work and play.
it’s not for you if: you have a shallow desk or do not need the wide 21:9 screen real estate.
11. Samsung 32″ Odyssey OLED G8 (G80SD)
A 32-inch 4K QD-OLED that doubles as a smart TV with a built-in streaming platform.
The Samsung Odyssey OLED G8 features a 32-inch 4K (3840×2160) QD-OLED panel with a 240Hz refresh rate and a 0.03ms response time. It includes Samsung’s NQ8 AI Gen3 Processor, which upscales lower resolutions to nearly 4K. The monitor runs Samsung’s Tizen smart TV platform, giving you built-in apps like Netflix and YouTube without needing a separate device. It also has the same Pulsating Heat Pipe cooling system as the G6 for burn-in protection.
Reviewers point out that the 4K OLED display is “gorgeous” with vibrant colors, deep blacks, and a 240Hz refresh rate that works great for games like Destiny 2. Some shoppers say a quirk: the monitor may briefly go to a black screen for about a second once nightly. A more serious complaint is that the smart TV UI can be intrusive, blocking the taskbar on wake, and the monitor requires a remote to manage output switching. It is a niche pick for someone who wants a monitor and a smart TV in one unit, but the software friction is real.
Unlike the pure-monitor-focused MSI MPG 321URX, the Samsung G8 adds smart TV functionality but introduces software annoyances that a simple monitor does not have.
Two-in-One
- 4K QD-OLED with 240Hz and AI upscaling
- Built-in smart TV platform for streaming
- Dynamic Cooling System with heat pipe
Software Friction
- Intrusive smart TV UI can interfere with desktop use
- Requires remote control for some settings
Perfect for: someone who wants a 4K OLED monitor that also functions as a bedroom TV for streaming.

This Alienware uses a 34.2-inch WQHD (3440×1440) QD-OLED panel with an 1800R curve, a 240Hz refresh rate, and a 0.03ms response time. The 1800R curve is less aggressive than LG’s 800R, providing a natural field-of-view expansion that is comfortable for both gaming and productivity. It covers DCI-P3 99.3% with Delta E <2 accuracy and is VESA DisplayHDR TrueBlack 400 certified, with a peak HDR brightness of 1000 nits.
Buyers report that the upgrade from a 144Hz VA panel to this QD-OLED is “a visual upgrade on the level of a GPU upgrade,” praising the smooth motion clarity and rich color contrast. Another reviewer bought it as a gift for a serious gamer who was blown away by the immersion in open-world games. The main downsides are the usual QD-OLED quirks: slight text clarity issues compared to a standard LCD, and lower brightness in very bright rooms. It also comes with a 3-year burn-in warranty.
Compared to the MSI MPG 341CQPX, the Alienware has a more conservative 1800R curve that is easier to use for desktop work, while the MSI offers a higher 98W USB-C power delivery.
Easy Immersion
- 34.2-inch QD-OLED with 1800R curve for natural ultrawide viewing
- 1000 nits peak HDR brightness
- 3-year burn-in warranty included

The INNOCN 49Q1S is a 49-inch OLED panel with a 1800R curve, a 5120×1440 resolution (essentially two 27-inch 1440p monitors side by side), and a 240Hz refresh rate with a 0.03ms response time. It includes a versatile connectivity hub with 2x DP 1.4, 1x USB-C 90W, 1x HDMI 2.1, and even an RJ45 ethernet port. The PiP/PbP mode lets you show content from two separate input sources on one screen, perfect for streaming and gaming simultaneously.
Buyers describe the image as “clear, crisp image with amazing resolution” and say the 240Hz refresh rate eliminates choppiness in games. One buyer mentioned that the screen feels “too short” compared to its width, causing excessive scrolling in long documents. The built-in speakers are described as “lacking,” though most gamers use external speakers anyway. The 1800R curve is a good fit for a monitor this wide, reducing eye strain while keeping the whole screen within your field of view.
Unlike any other monitor on this list, the INNOCN 49Q1S gives you a 49-inch dual-QHD canvas that is like having two 27-inch 1440p monitors with no bezel gap. However, it lacks the QD-OLED vibrancy of Samsung or MSI panels.
Massive Canvas
- 49-inch 32:9 ultrawide replaces two 1440p monitors
- USB-C with 90W charging and built-in RJ45 ethernet
- PiP/PbP mode for dual-source input

Ideal for: sim racers, flight sim enthusiasts, and multitaskers who want a bezel-free dual-monitor replacement.
Not for: productivity users who need a taller vertical screen for long documents or code.
Understanding the Specs
Refresh Rate (Hz)
This is how many times per second the image on your screen refreshes. A 240Hz monitor updates 240 times each second, making motion look incredibly smooth and reducing the blur you see when you spin the camera quickly. Jumping from a standard 60Hz or 144Hz monitor to 240Hz is a big difference — you will see enemy movements more clearly and your mouse cursor will feel more responsive. The Alienware AW2725DF goes even higher at 360Hz, which gives competitive gamers an extra edge in fast-paced titles.
Response Time (ms)
This measures how quickly a pixel can change from one color to another, measured in milliseconds. A 0.03ms response time is nearly instantaneous, which means you will not see any ghosting or trails behind fast-moving objects. Traditional LCD monitors typically have response times around 1ms to 4ms, so OLED panels are in a league of their own for motion clarity. This is why OLED monitors feel so much sharper during fast gameplay — the pixels simply keep up with your movements.
