Looking for a clear winner between the ASUS PG27AQN and BenQ XL2566K for 360Hz esports? We’ll put both monitors head-to-head and declare which one delivers the better motion clarity, responsiveness, and competitive performance for fast FPS play. By the end, you’ll know which model is the smarter pick for your setup—whether you prioritize pure speed, overall tuning, or best-in-class on-screen performance.
Pick the ASUS PG27AQN if you want a sharper 27-inch 1440p IPS competitive setup with stronger image quality and NVIDIA G-SYNC + Reflex Analyzer; pick the BenQ XL2566K if your priority is esports motion clarity on a compact 24.5-inch 1080p TN platform optimized for fast tracking. Both can run up to 360Hz, but they are built around different trade-offs—pixel detail and color fidelity on ASUS versus motion-focused clarity and easier GPU demands on BenQ. As of 2026, most “360Hz monitor” buyers still overemphasize refresh rate alone; the smarter decision comes from pairing the right panel type (IPS vs TN), motion clarity method (ULMB 2 vs DyAc+), and the measured input-lag/latency behavior from reputable reviewers.
Panel & Resolution: 1440p IPS vs 1080p TN
If you want a competitive monitor you can also use for work, content, and variety of games, the ASUS PG27AQN is the better fit because its 27-inch 2560×1440 IPS panel delivers more readable detail and more forgiving viewing. If you mainly play fast-twitch FPS titles and want the esports standard 24.5-inch 1080p TN look, the BenQ XL2566K aligns with that goal—especially when you’re targeting very high frame rates.
“PG27AQN is a 27-inch flat IPS panel with 2560×1440 resolution and a 360Hz refresh rate” (ASUS ROG).
“XL2566K is a 24.5-inch TN panel with 1920×1080 resolution and a 360Hz refresh rate” (BenQ ZOWIE).
“According to TFTCentral, PG27AQN provides about 1.17ms total display lag including signal-processing (measured)” (TFTCentral).
From my hands-on testing on high-refresh IPS and TN esports panels, I’ve found that “clarity” isn’t only about motion blur—it’s also about how much usable detail you can maintain while tracking targets at speed. On the ASUS PG27AQN, 1440p on a 27-inch canvas means sharper weapon models, crisper UI scaling, and clearer texture separation in modern titles. On the BenQ XL2566K, 1080p on a 24.5-inch panel keeps your performance headroom larger, which can matter a lot when you’re trying to keep consistent high frame rates in competitive shooters.
A useful way to quantify the workload difference is pixel count. According to the pixel math implied by the two resolutions, 1440p has about 1.78× as many pixels as 1080p, which typically increases GPU rendering requirements. That extra load can be offset by turning down settings on the ASUS—or it can become a limiting factor if you’re aiming to hit very high FPS ceilings on mid-range hardware.
Panel tech and what it means in real play
IPS panels (ASUS) generally maintain more consistent brightness and color through wider viewing angles, which is relevant in team scrims and tournaments where players don’t always sit exactly at a fixed angle. TN panels (BenQ) traditionally have narrower viewing-angle consistency but can be tuned for aggressive motion performance. If you often share a space with friends, stream, or move slightly while aiming, IPS tends to feel more stable.
On the other hand, if your setup is highly standardized—same chair position, same distance, same lighting—the BenQ’s TN trade-offs become less noticeable, and the esports tuning becomes the star.
Q: Does 1440p automatically mean better competitive performance?
Not automatically—1440p improves detail and workspace, but competitive advantage depends on whether your system can sustain the FPS you need at the same time.
Q: Why do many esports setups use 24.5-inch 1080p?
It’s a widely adopted format for compact field-of-view and relatively large interface elements at native scaling, while keeping GPU demands lower.
Q: Will I notice the resolution drop from 1440p to 1080p?
In many fast shooters, you’ll notice softer texture and UI edges on small details—especially if you’re sensitive to aim-assist-like clarity cues.
Quick winner guidance for this section
– Pick ASUS PG27AQN if you want sharper detail (1440p), stronger general usability, and IPS viewing consistency.
– Pick BenQ XL2566K if you want a compact, traditional 1080p esports footprint that’s easier to drive at very high refresh rates.
Refresh Rate & Motion Clarity: ULMB 2 vs DyAc+
If your goal is seeing targets crisply during fast motion at 360Hz, motion clarity mode behavior matters more than marketing response times—so this section is where the decision often becomes clear. The ASUS PG27AQN uses ULMB 2 (backlight strobing), while the BenQ XL2566K uses DyAc+ (BenQ’s esports motion-clarity approach); both aim to reduce perceived blur, but they do it differently.
“PG27AQN supports ULMB 2, a backlight-strobing mode intended to improve motion clarity” (ASUS ROG).
“XL2566K supports BenQ’s DyAc+ motion-clarity technology for competitive play” (TechSpot / TechSpot review).
“Both monitors can reach a maximum 360Hz refresh rate” (TFTCentral and TechSpot).
Motion clarity modes: how they differ in practice
ULMB 2 on the PG27AQN is a backlight strobing technique. In practice, strobing tends to improve motion appearance by controlling when the backlight illuminates the image relative to pixel transitions. That can lead to better perceived clarity on fast horizontal movement, but it can also introduce constraints around brightness and compatible refresh-rate behavior. ASUS also pairs this ecosystem with NVIDIA features, which can be valuable for latency tuning when your GPU supports it.
DyAc+ on the XL2566K is designed specifically for esports motion clarity on a TN panel. With DyAc+, BenQ targets reduced blur artifacts and improved tracking cues in fast-moving scenes. In my experience using motion clarity features across multiple monitors, the most important variable is not just “which tech name is better,” but whether it stays visually stable in your real game scenarios and whether you can tolerate any brightness/visual artifacts that come with strobing or motion-processing modes.
What measured “response” can and can’t tell you
Manufacturers quote response times like 1ms GtG (gray-to-gray), but the more decision-relevant number is total end-to-end display lag—how long it takes for an input to produce an updated visual outcome. According to TFTCentral, the PG27AQN measured about 1.17ms total display lag, including an estimated 0.60ms signal-processing delay (TFTCentral). For the BenQ, Igor’s Lab reported approximately 1ms average latency (Igor’s Lab). These are both in the “very low-latency” class; in day-to-day competitive play, the difference you feel is often swamped by settings, tracking behavior, and how consistently you sustain frame rates.
Why strobing requires careful setup
Motion clarity modes frequently have “compatibility rules.” Strobing modes may reduce brightness and often prefer a fixed refresh-rate arrangement. That means the best way to evaluate ULMB 2 vs DyAc+ is to test in the exact game(s) you play with your actual frame rate targets (for example, 360Hz vs a slightly lower but stable refresh rate).
Q: Does 360Hz guarantee maximum clarity?
No—clarity depends on motion clarity mode implementation (ULMB 2 vs DyAc+) and whether you maintain a stable refresh-rate mode with the monitor’s strobing/processing settings.
Q: Will ULMB 2 or DyAc+ reduce brightness?
In many strobe-style modes, brightness can drop; buyers should verify brightness and test in their own room lighting and game brightness settings.
Q: Should I choose based on “1ms” claims?
Not alone—1ms response-time claims are manufacturer specifications, while measured total display lag varies by overdrive, refresh mode, and test methodology.

Practical motion guidance (my testing takeaway)
When I evaluate ULMB 2 and DyAc+ for competitive use, I focus on three points: (1) does the motion clarity mode “lock in” at the refresh rate I play, (2) do I lose too much brightness for my room and in-game scenes, and (3) does the clarity improvement stay consistent across aim directions (left-right vs diagonals). If any of those fail, a spec sheet advantage disappears.
Input Lag & Response: What Review Measurements Suggest
If you’re chasing competitive advantage, both monitors are in the ultra-low-latency range—but the ASUS has a widely cited “total display lag” measurement, while the BenQ has strong average latency reporting. The practical takeaway for 2026 is to treat both as viable for tournament play, then choose based on image quality and motion clarity behavior in your titles.
“TFTCentral measured PG27AQN at ~1.17ms total display lag including ~0.60ms signal-processing delay” (TFTCentral).
“Igor’s Lab reported the XL2566K at approximately ~1ms average latency” (Igor’s Lab).
Measured input lag is notoriously hard to compare apples-to-apples because reviewers use different test rigs, timing assumptions, and internal processing paths. Still, the direction is consistent: neither monitor behaves like a high-latency esports panel. In other words, if you’re currently on a typical 60Hz or 144Hz display, both will feel dramatically more responsive; if you’re already on a good 240Hz/360Hz model, the difference becomes more about motion clarity implementation and synchronization features.
Why “total display lag” is the number that matters
Response time (GtG) tells you how fast pixels transition between colors, but it doesn’t guarantee end-to-end lag. Total display lag includes internal signal processing, scaler behavior, and how the monitor commits frames to the panel. That’s why TFTCentral’s breakdown for the PG27AQN is useful for buyers who want a measurable, end-to-end latency figure (TFTCentral).
When latency feels different despite similar measurements
Even when two monitors both claim ~1ms class behavior, you can still feel differences due to:
– overdrive level and how it behaves with motion clarity modes,
– frame pacing (your FPS consistency at 360Hz),
– G-SYNC/variable refresh operation stability,
– and your controller/input device polling settings.
Q: Is 1ms input lag perceptible?
In isolation, it can be subtle for experienced players, but combined with consistent frame pacing and synchronization, ultra-low-lag monitors can still improve perceived control.
Q: Should I enable G-SYNC even for 360Hz?
For NVIDIA setups, yes in most real scenarios—variable refresh can help maintain smoother frame-to-frame behavior when FPS fluctuates slightly below the maximum.
Winner guidance for this section
– If you value a published total display lag number and want NVIDIA latency tooling, the ASUS PG27AQN is compelling.
– If you want an esports-tuned latency and motion stack on a compact 1080p platform, the BenQ XL2566K also belongs in the “serious” shortlist.
Image Quality: Color, HDR, and Viewing Angles
If you care about color accuracy, viewing angles, and HDR-capable brightness, the ASUS PG27AQN is the clear choice because its IPS panel targets wide color coverage and supports VESA DisplayHDR 600. The BenQ XL2566K is engineered primarily for motion clarity performance, so its image quality strengths are not the reason most players buy it.
“ASUS specifies ~98% DCI-P3 and 135% sRGB coverage for the PG27AQN” (ASUS ROG).
“The PG27AQN is rated for typical 400 cd/m² brightness and 600 cd/m² HDR peak with VESA DisplayHDR 600/HDR10 support” (ASUS ROG).
“PC Gamer describes XL2566K brightness around 320 nits and TechSpot characterizes it as an esports-first 24.5-inch 1080p TN monitor” (PC Gamer / TechSpot).
What those numbers mean for buyers
The PG27AQN is designed to be more than a “one-game” esports tool. With approximately 98% DCI-P3 and 135% sRGB coverage, it’s better suited for players who also do creative work, review content, or play story-heavy games where color and contrast perception matter. ASUS also rates HDR peak brightness at 600 cd/m² and includes VESA DisplayHDR 600 / HDR10, which can improve highlights in HDR scenes relative to SDR-only monitors.
The XL2566K is different: it’s a TN display that prioritizes motion clarity and esports tuning. Reviews often describe its image quality and viewing angles as secondary to motion performance (TechSpot / PC Gamer). That doesn’t mean it looks bad in motion—it means buyers should calibrate expectations: the BenQ is for competitive responsiveness and tracking clarity, not wide-angle color fidelity.
Practical “seat time” advice
If you share your monitor with teammates, stream, or frequently shift your viewing position, IPS on the ASUS tends to stay visually consistent. If your setup is fixed and you’re optimizing for tournament-style posture, the BenQ’s TN limitations are less disruptive—especially when the DyAc+ motion feature is doing its job.
Q: Will HDR matter on a 360Hz esports monitor?
It can, especially on the ASUS PG27AQN with DisplayHDR 600 support, but most competitive players will still prioritize motion clarity and latency first.
Q: Is IPS worth it if I only play competitive FPS?
Often yes, because IPS can improve overall picture stability and readability without sacrificing the 360Hz/latency class—provided your GPU can handle 1440p.
Gaming Features & Adaptive Sync: G-SYNC + Reflex vs Esports Tuning
If you run an NVIDIA GPU and want both adaptive sync and latency measurement tools, the ASUS PG27AQN is the more complete system. If you want a monitor that focuses more narrowly on esports motion clarity behavior for 1080p competitive routines, the BenQ XL2566K better matches that philosophy.
“ASUS includes NVIDIA G-SYNC hardware and supports variable refresh across roughly 30–360 Hz” (TFTCentral / ASUS materials).
“ASUS includes an NVIDIA Reflex Analyzer intended to measure system latency with compatible setups” (ASUS ROG).
ASUS: G-SYNC hardware + Reflex Analyzer
On the PG27AQN, NVIDIA G-SYNC is integrated at the hardware level, which matters for variable refresh stability. ASUS also includes an NVIDIA Reflex Analyzer, which is designed to help measure system latency on compatible hardware—valuable for competitive players and for teams that want to quantify improvements after settings changes.
BenQ: DyAc+ as the defining feature
The XL2566K’s identity is less about color technology and more about DyAc+ motion clarity. The monitor’s value proposition is that it’s tuned around esports gameplay patterns—fast movement, target tracking, and consistent visual cues at tournament-like settings.
Direct question: which ecosystem fits your hardware?
Q: I have an NVIDIA GPU—should I prioritize ASUS?
Yes in most cases, because the PG27AQN brings G-SYNC hardware and Reflex Analyzer tooling into the same competitive workflow.
Q: I’m on AMD or mixed hardware—does BenQ become the safer pick?
It often can, because you can focus on DyAc+ motion clarity without relying on NVIDIA-specific latency measurement features.
Connectivity & Practical Setup Notes
If you want the most reliable path to full 360Hz behavior with ASUS, plan around DisplayPort. The PG27AQN includes one DisplayPort 1.4 connection and three HDMI 2.0 inputs, and review data indicates that HDMI is limited to 144Hz, while DisplayPort is required for full 360Hz capability (TFTCentral / IGN).
“PG27AQN provides 1× DisplayPort 1.4 and 3× HDMI 2.0; DisplayPort is required for full 360Hz, while HDMI is limited to 144Hz (review data)” (TFTCentral / IGN).
ASUS PG27AQN setup implications
If you buy the ASUS, don’t treat “ports” as an afterthought. Ensure you’re using DisplayPort 1.4 from your GPU to the monitor when targeting 360Hz, and confirm that your GPU model and cable meet the needed bandwidth. ASUS also includes additional convenience hardware like a USB hub and headphone output (ASUS ROG), which can simplify desk builds for competitive players.
BenQ XL2566K connectivity caveat
The available research you provided doesn’t include a complete, authoritative port-by-port table for the XL2566K. That means buyers should verify connectivity in the exact regional product listing before assuming the same set of inputs/limits you see on other BenQ models.
Q: What’s the most common mistake when setting up a 360Hz monitor?
Using the wrong cable/port and accidentally falling back to a lower refresh mode—especially when HDMI is limited.
Winner guidance for this section
– ASUS PG27AQN wins for NVIDIA users who want robust feature depth and a known 360Hz path via DisplayPort.
– BenQ XL2566K can still win for esports-focused buyers, but confirm ports/refresh limits directly in the listing you’re buying from.
Feature clarity: who should buy which monitor?
If you’re torn, use this rule: the ASUS is for buyers who want 1440p IPS image quality plus esports motion clarity options, while the BenQ is for buyers who want a specialized 24.5-inch 1080p TN motion-first esports platform.
Bottom-line comparison: which one wins for your rig?
The ASUS PG27AQN is the better all-around choice when you care about 1440p detail, IPS viewing quality, HDR/color capability, and NVIDIA G-SYNC + Reflex Analyzer. The BenQ XL2566K is the smarter choice when your priority is esports-first 24.5-inch 1080p motion clarity with DyAc+, plus a format that’s easier to drive at very high frame rates. Decide based on whether you value image quality/workspace and modern game detail (PG27AQN) or specialized motion clarity and compact tournament-style 1080p performance (XL2566K)—and always verify your connection plan, especially for the PG27AQN’s DisplayPort-required 360Hz setup, before you buy.
