Short answer: buy the Samsung Odyssey OLED G6 only when the exact model is the 27-inch G60SD and its local price, ports and warranty suit your setup. The G60SD is a 2560×1440 OLED monitor rated at 360 Hz with a stated 0.03 ms response time and AMD FreeSync Premium Pro. MSI’s MPG 271QRX and ASUS’s ROG Strix OLED XG27ACDNG match that core resolution, refresh-rate and response-time class while adding different connectivity and warranty details. There is no controlled, published head-to-head test here that proves one panel looks or feels better, so the sensible choice depends on price, stock, USB-C or KVM requirements, desk fit, warranty coverage and whether your computer can actually drive high frame rates at QHD.
First, identify which Samsung G6 you are comparing
“Odyssey OLED G6” is ambiguous because Samsung now uses the G6 name for several monitors. This comparison treats it as the Odyssey OLED G6 G60SD, the model Samsung’s US product page identifies as a 27-inch, 2560×1440 OLED display running at 360 Hz. Samsung separately lists the G60SF at 500 Hz and the G61SD at 240 Hz. Those are different products, not alternate refresh-rate modes of the same monitor.
| Samsung model | Panel and resolution | Maximum refresh rate | How it relates to this article |
|---|---|---|---|
| G60SD | 27-inch QHD OLED | 360 Hz | The Samsung model compared below |
| G60SF | Not stated in the cited product summary | 500 Hz | A separate G6 variant; do not assume G60SD specifications apply |
| G61SD | Not stated in the cited product summary | 240 Hz | A separate G6 variant; not a 360 Hz alternative |
There is another naming trap. Samsung’s December 24, 2025 announcement describes a next-generation IPS Odyssey G6 called the G60H, with QHD operation up to 600 Hz and a dual-mode 1,040 Hz setting at HD resolution. That announcement concerns the 2026 lineup and should not be used as evidence about the OLED G60SD’s panel or performance.

The closest alternatives supported by the available manufacturer specifications are MSI’s MPG 271QRX and ASUS’s ROG Strix OLED XG27ACDNG. Both are 26.5-inch-class QHD QD-OLED monitors rated for 360 Hz and 0.03 ms GtG. Samsung describes the G60SD as a 27-inch QHD OLED and states a 0.03 ms response time; the cited Samsung summary does not specify a GtG test method. A response-time number from one manufacturer is therefore not automatically a laboratory comparison with another manufacturer’s number.

What 360 Hz at 1440p actually means
Refresh rate is a ceiling, not a guaranteed frame rate
A 360 Hz panel can refresh up to 360 times per second, but it cannot display 360 unique frames when the game and computer produce fewer. To exploit the full refresh capability, the system must render close to 360 frames per second at 2560×1440 in the games you play. Competitive titles with modest graphics settings are more likely to approach that range than visually demanding single-player games. The monitor does not increase the game’s frame rate by itself.
QHD changes the hardware requirement
2560×1440 renders substantially more pixels than 1920×1080. A graphics card that sustains very high frame rates at 1080p may not sustain them at QHD. Before paying a premium for a 360 Hz model, check current frame-rate results for your own processor, graphics card, game version and settings. If your normal frame rate is far below 360, a lower-refresh OLED may deliver better value, while a 360 Hz display still leaves headroom for future hardware and lighter games.
Adaptive sync is the practical safety net
FreeSync Premium Pro on all three models is intended to coordinate the display refresh with variable frame rates. ASUS also lists G-SYNC Compatible support. Compatibility can depend on the graphics card, driver and connection, so enable the appropriate mode in the monitor menu and graphics-driver control panel, then confirm that the game is actually varying refresh rate rather than running with it disabled.
Connectivity can matter more than a one-inch size difference
When MSI’s USB-C port is useful
The MPG 271QRX lists USB-C DisplayPort Alt Mode with 90 W power delivery. A compatible laptop can carry video over one cable while receiving up to the monitor’s stated 90 W charging capability. The actual charging rate depends on the laptop and cable, and a gaming laptop may still need its own power adapter under load. The monitor also lists DisplayPort 1.4a and two HDMI 2.1 inputs, giving it a clear specification advantage for mixed desktop, laptop and console setups when those ports are present on the purchased regional model.

When ASUS’s KVM and hub are the deciding features
The XG27ACDNG lists USB-C with 90 W power delivery, three USB-A hub ports and a KVM switch. KVM lets one keyboard and mouse serve two connected computers, with the monitor switching the USB peripherals along with the selected video source. This is valuable for a work laptop and gaming desktop sharing one desk. It is unnecessary if you use one computer and already have a separate USB hub.
What to verify on Samsung
The cited Samsung G60SD summary establishes the panel, refresh rate, response claim and adaptive-sync support but does not provide a complete port list in the material available here. Check the exact regional SKU before purchase, especially if you require USB-C charging, HDMI 2.1, a USB hub or a particular DisplayPort standard. Do not infer G60SD connectivity from a similarly named G60SF, G61SD or G60H.
Warranty and OLED burn-in coverage
OLED buyers should read the warranty rather than rely on a retailer’s short specification list. MSI’s cited MPG 271QRX specification says its three-year warranty includes panel burn-in. ASUS gives the same three-year, burn-in-inclusive detail for the XG27ACDNG. Samsung’s UK page says burn-in during normal use is covered, with exclusions; the applicable terms for a US or other country purchase may differ. Coverage can also depend on registration, proof of purchase, usage conditions and what the manufacturer defines as abnormal use.
- Save the invoice and record the exact model suffix and serial number.
- Read the local warranty document for burn-in exclusions, claim deadlines and pixel policies.
- Confirm whether firmware, panel-care cycles or usage limits are required for coverage.
- Buy from a seller that clearly handles returns if the panel arrives damaged or has an immediate defect.
None of these warranty statements is an independent prediction of panel lifespan. They are the manufacturers’ published coverage terms.
Price, availability and the limits of the buying-guide evidence
Prices and stock are highly time- and market-sensitive. PC Gamer’s guide, updated July 28, 2026, listed the MPG 271QRX at $799 / £999 at the time of publication and selected it as its best 1440p OLED monitor. The guide also identified its premium price and poor font rendering as drawbacks. Those figures are dated guide prices, not current quotes, and the selection is an editorial recommendation rather than a controlled victory over Samsung or ASUS.

The manufacturers themselves warn that specifications and availability can vary by region. Compare the delivered local price, return policy and warranty—not a US list price copied into another country. A discount can make the G60SD the better buy one week and the MSI or ASUS the better buy the next. If two models are within a small price difference, choose based on the connection or warranty feature you will actually use instead of assuming the 0.03 ms claims separate them.
Samsung reported that its monitors above 144 Hz represented 18.8% of global gaming-monitor revenue in 2025, citing IDC’s Worldwide Quarterly Gaming Tracker for Q3 2025. That is Samsung’s reporting of IDC data, not an independent ranking of these three models, and it does not indicate which monitor an individual buyer should select.
Which monitor should you buy?
Choose the Samsung G60SD when
- You have confirmed that the listing is the 360 Hz OLED G60SD, not the 500 Hz G60SF, 240 Hz G61SD or IPS G60H.
- Its local price is lower or its availability and return terms are better than the alternatives.
- You prefer the 27-inch size and do not need USB-C charging, a KVM switch or a USB hub that Samsung’s regional specification does not list.
- Your retailer provides acceptable local OLED warranty coverage and you have verified the exact port layout.
Choose the MSI MPG 271QRX when
- You need USB-C video with 90 W power delivery for a laptop-oriented desk.
- DisplayPort 1.4a and two HDMI 2.1 inputs match your desktop, laptop and console connections.
- The published three-year warranty including panel burn-in is stronger or clearer in your market than Samsung’s local terms.
- You accept PC Gamer’s warning that it is expensive for 1440p and can have poor font rendering, and the current price still makes sense.
Choose the ASUS XG27ACDNG when
- You will use a KVM switch to share a keyboard and mouse between two computers.
- You need USB-C 90 W charging plus three USB-A hub ports.
- You want the manufacturer-listed combination of FreeSync Premium Pro and G-SYNC Compatible support.
- Its three-year burn-in-inclusive warranty and local price beat the alternatives.
Choose none of them yet when
- Your graphics hardware rarely approaches the frame rates your games need to make 360 Hz useful.
- You cannot verify the seller’s exact model suffix, ports, return window or warranty.
- A lower-refresh OLED or a less expensive QHD display would leave budget for a graphics-card upgrade that improves your actual frame rate.
A purchase checklist that avoids the common mistakes
- Copy the full model code. It must say G60SD for the Samsung comparison. Record the MSI or ASUS suffix exactly as shown on the invoice.
- Confirm the native mode. Look for 2560×1440 at 360 Hz in the manufacturer specification, not merely “up to” language for another resolution or model.
- Match ports to your devices. Count the required DisplayPort, HDMI, USB-C, USB-A and charging connections before ordering.
- Check your computer’s output. Verify that the graphics card, cable and driver support QHD at the desired refresh rate. Use a certified cable supplied or recommended for the monitor where possible.
- Calculate delivered cost. Include tax, shipping, stand or arm accessories and any import cost. Compare local currency prices on the same date.
- Read the local warranty. Confirm burn-in language, exclusions, dead-pixel policy and who pays return shipping.
- Check desk dimensions. Measure width, depth, VESA compatibility and clearance for the stand. The 27-inch Samsung is physically larger than the 26.5-inch-class MSI and ASUS panels, even though their visible diagonal measurements are close.
- Plan OLED care. Enable the monitor’s panel-care features as instructed, vary static desktop elements and avoid leaving a fixed image on screen for long periods. These are sensible operating practices, not a guarantee against burn-in.
Setup after installation
Set the operating-system refresh rate
After connecting the monitor, open the operating system’s advanced display settings, select the monitor and choose 2560×1440 at 360 Hz. If 360 Hz is missing, check the cable, input, graphics-driver version and whether the monitor is in a mode that limits refresh rate. Some displays expose high-refresh modes only after enabling a specific input or compression setting in the on-screen display.
Configure adaptive sync and frame limits
Enable the monitor’s adaptive-sync option, then enable the matching feature in the graphics driver. Set an in-game frame limit appropriate to the refresh range you can sustain; a stable frame rate is usually more useful than an uncapped rate that repeatedly collides with the refresh ceiling. Validate with the game’s own frame counter or a trusted overlay rather than assuming the monitor is receiving 360 frames per second.
Use the connection features you paid for
For MSI or ASUS USB-C, use a full-featured USB-C cable that supports DisplayPort Alt Mode and the required power level. On ASUS, connect the keyboard and mouse to the monitor’s USB hub and configure the KVM input assignments before switching computers. If you do not need these functions, a direct DisplayPort connection from the gaming PC is the simplest path to QHD high refresh.

What is—and is not—established by the available evidence
Official manufacturer pages are the strongest evidence for model names, stated specifications, ports and warranty language. They do not establish that one monitor has lower input latency, better HDR, superior text clarity or more accurate color than another unless an independent test measures those properties under comparable conditions. The cited material contains no controlled laboratory head-to-head result for the G60SD, MPG 271QRX and XG27ACDNG.
The 0.03 ms figures should therefore be read as published response-time claims, with MSI and ASUS specifying GtG while Samsung’s cited page presents a response-time figure without the same qualification. Panel type also differs: Samsung identifies the G60SD as OLED, while MSI and ASUS identify QD-OLED. That distinction can affect characteristics such as subpixel layout and text rendering, but the supplied sources do not provide a standardized measurement that ranks them.
Samsung executive vice president Hun Lee said in the company’s December 2025 announcement, “With this year’s Odyssey lineup, we’re introducing display experiences that simply weren’t possible even a year ago.” The statement is promotional language about Samsung’s 2026 lineup, not an independent performance finding and not evidence that the G60SD beats the other 360 Hz monitors.
Bottom line for a real buying decision
Start with the exact model and local terms, not the “G6” label. The Samsung G60SD, MSI MPG 271QRX and ASUS XG27ACDNG all occupy the same compelling headline class: QHD OLED or QD-OLED, 360 Hz and a stated 0.03 ms response figure. MSI is the practical laptop-and-warranty choice when its USB-C 90 W port and three-year burn-in coverage matter. ASUS is the strongest fit for a two-computer desk because of its USB-C, hub and KVM combination. Samsung is the sensible choice when the confirmed G60SD is cheaper or easier to obtain, its 27-inch format fits your desk and its regional warranty and ports meet your requirements. If your PC cannot feed QHD at high frame rates, spend less on refresh rate or redirect the budget to hardware that will improve the games you actually play.
