OLED panels have quickly become the norm among premium gaming monitors, but few offer refresh rates as high as MSI's MPG 271QR QD-OLED X50 ($799). With a whopping 500Hz ceiling and excellent color range and contrast, MSI’s latest 27-inch display is the best of both screen worlds, offering impressive visuals alongside esports-level performance. It's got some other neat features to boot, such as a USB Type-C port with 98 watts of power delivery, as well as a range of quality-of-life features powered by AI.

We're not 100% sold on the AI stuff, and the monitor itself looks a bit plain, but those are quibbles. The MSI MPG 271QR QD-OLED X50 is one of the best 27-inch gaming panels to visit PC Labs in some time, and this 1440p/500Hz monitor earns our Editors' Choice award for esports monitors. The MSI MPG 271QR QD-OLED X50 measures 16.4 by 23.9 by 9.5 inches (HWD) with its stand, and it weighs 18.5 pounds.

The panel itself is remarkably thin; the stand, though, is solid and bulky, with a wide, chunky base. It takes up some extra space on the desktop, but I put the big footprint to good use: The base was flat enough to store simple stationery items like Post-It Notes and pens atop it. All in all, MSI delivers a no-frills look here, but that may not be a problem for some. In keeping with that, the color scheme is just as plain: all black, with thin bezels framing the screen.

The only aesthetic flourishes show up on the rear of the machine, where you’ll find MSI’s familiar dragon branding, with a touch of RGB lighting at the top of the panel, just beside the vents. MSI expects you to use this panel with a headset, presumably; the MSI MPG 271QR QD-OLED X50 has no built-in speakers. The port hub, however, offers plenty of connection options: two USB Type-A connections, one USB Type-B, and a headphone jack, alongside four video inputs.

Those comprise two HDMI 2.1 ports, a DisplayPort 2.1, and one Type-C DisplayPort Alt-Mode port with 98 watts of power delivery. You probably know that HDMI 2.1 ports allow smoother, low-latency experiences on the Sony PlayStation 5, Microsoft Xbox Series consoles, and even the Nintendo Switch 2 at up to 120Hz, but DisplayPort 2.1 is a lot newer. It offers more than double the bandwidth of DisplayPort 1.4, allowing you to maintain higher resolutions and refresh rates without the compression demanded by DisplayPort 1.4.

It's crucial on a panel with this kind of refresh rate. The OLED panel supports a 2,560-by-1,440-pixel (1440p) native resolution at a whopping 500Hz refresh rate. It’s only 27 inches, but for some competitive gamers, a smaller display is ideal. With less screen real estate, your eyes don’t have to move very far to react to what you're seeing. And thanks to the OLED panel, gamers won’t have to sacrifice visual quality for high performance.

There’s even an option for the panel to limit the picture to a 24.5-inch window size. That's an option some esports gamers may appreciate toggling on, under some circumstances. A 24.5-inch-diagonal picture may allow them to fit the entire game screen into their field of view in a way the full 27 inches might not. But the MSI MPG 271QR QD-OLED X50 packs in a lot more than just a pretty picture. The monitor has some of the best HDR I’ve seen in a gaming display, and it also offers something called "EOTF boost." EOTF stands for Electro-Optical Transfer Function (not terribly telling by itself, I must admit), and this feature, exclusive to MSI monitors, ostensibly delivers higher, more consistent brightness and more accurate HDR implementation, according to the company.

My eyes tell me there's something to it; when viewing HDR-specific content, you can really see the difference in overall image brightness. Now, as for the AI stuff. MSI has equipped the monitor with a neural processing unit (NPU), giving it some genuine local artificial-intelligence clout. Let me set your expectations: It's not like MSI plugged ChatGPT or Claude into your monitor; most of the monitor features here powered by AI center around power-saving and privacy, while some actually help you in-game.

The AI Care Sensor, for instance, uses a CMOS sensor to capture images of the area in front of the monitor every 0.2 second. Working in tandem with the NPU, the monitor can identify when a person is in front of it. This lets the AI do some pretty useful tricks, such as waking automatically when you approach and going to sleep when you leave. It can also determine whether what it's dealing with is an actual human, so the monitor won’t accidentally be triggered by, say, a pet or a stuffed animal.

Another NPU-powered feature dims your screen when you’re not looking at it, saving power and protecting your screen, not to mention enhances privacy if used in a collaborative environment. On the privacy topic, MSI claims that all visual data is processed locally in real time and instantly converted into digital signals without any storage. No images are saved or transmitted. Additional AI features include AI Vision, which automatically adjusts brightness and saturation to match the scene you're watching, and an AI Crosshair that changes color so it doesn't blend into the game's background at any given moment.

In my experience, I found these two features interesting but marginal, though I’m sure some gamers would feel otherwise. The monitor also supports AMD FreeSync Premium Pro and is Nvidia G-Sync Compatible, with an HDR True Black 500 certification. It's VESA ClearMR 21000 certified, too, which ensures motion clarity by reducing ghosting and blur. Whether you’re playing casually or competitively, the MSI MPG 271QR QD-OLED X50 makes for an impressive gaming monitor.

But our analysis wouldn’t be complete until we put it through our standard series of benchmark tests, employing Portrait Displays' Calman calibration software and our Klein K-10A colorimeter. We also ran it through a gauntlet of games to measure input lag and judge its real-world performance. We took these readings with out-of-the-box settings. In our first test, we benchmarked brightness using the MPG 271QR’s default SDR profile.

Under these conditions, we measured a maximum brightness of 276 nits, just below the 300-nit SDR rating. Peak HDR brightness was much better: 440 nits at an 18% window and 900 nits at a 2% window. This comes in slightly under the typical HDR listed on the monitor’s product page, but remember that these are out-of-the-box settings. There’s potentially room for improvement through calibration or toying with other presets.

The MPG 271QR has a rated contrast ratio of 1,500,000:1. This sky-high figure indicates the display's deftness at producing deep blacks alongside bright whites, resulting in improved image quality in both light and dark scenes. OLED contrast ratios are essentially infinite, so number comparisons in the millions are mostly meaningless. On the whole, OLED panels deliver superior, deep blacks and vibrant detail, and they are the choice for gamers and content creators who play HDR-enhanced games or work with HDR content.

When measuring the monitor’s color gamut, I found that the MPG 271QR spans 98.9% of the Adobe RGB color space, 156.3% of the sRGB gamut (see the chart above), and 98.9% for DCI-P3 (see the chart below). That’s excellent color coverage, albeit what we’ve come to expect from OLED panels. The MSI MPG 271QR QD-OLED X50 doesn't just deliver sterling visuals—it also promises superior game performance.

With a 500Hz refresh rate at the ready, the display supports all kinds of gaming scenarios, from casual to competitive play. To see whether the MPG 271QR can compete with other esports-ready displays, I used the Leo Bodnar 4K Input Lag Tester to measure its performance across various refresh-rate and resolution combinations. I started my input-lag tests at full HD (1080p). At 1080p/60Hz, I recorded 9.9ms of input lag, and at 1080p/120Hz, noted down 5ms.

At 1080p/240Hz, the measurement was a stellar 2.5ms. Moving to QHD (1440p) resolution, the monitor recorded 6.3ms of input lag at 60Hz, and 9ms at 120Hz. The Bodnar device can't measure above 120Hz at 1440p, or above 240Hz at 1080p, due to the limitations of the hardware, but in general, input lag decreases as refresh rate increases. These results compare favorably with the premium-priced Alienware 27 280Hz (AW2725D), which has 13.8ms of lag at 1080p/60Hz and 7.5ms at 1440p/60Hz, as well as the AOC Q27G4ZD, which recorded 14.6ms at 1080p/60Hz and 7.5ms at 1440p/60Hz.

It also easily clears the LG 27 UltraGear OLED (27GX790A)’s input lag of 26.7ms at 1080p/60Hz and 7.3ms at 1440p/60Hz. The MSI MPG 271QR QD-OLED X50 is an impressive 1440p/500Hz gaming monitor, with panel quality, speed, and AI smarts that make it formidable for esports and productivity alike.
