BenQ Zowie XL2540K Review: 240Hz TN Built for Competitive FPS

Panel type wars are mostly settled arguments at this point. TN loses on colour, IPS loses on contrast, VA loses on speed. The question that actually matters is whether a specific monitor executes its panel's strengths well enough to justify the asking price, and for the BenQ Zowie XL2540K, the answer is yes, with a fairly narrow asterisk attached. This is a 240Hz TN panel built almost entirely around competitive FPS gaming, and it does that job with a precision that over 728 owner reviews and a 4.7-star average back up convincingly. It is not trying to be a content creation screen. It is not trying to win a colour accuracy contest. It knows exactly what it is.

The verdict is this: if you play fast-paced competitive shooters at a high level, the XL2540K is one of the most purpose-built tools in the upper mid-range bracket. The 240Hz refresh, BenQ's DyAc (Dynamic Accuracy) motion blur reduction technology, the smaller footprint stand, and the XL Setting to Share feature are all genuinely useful additions rather than marketing filler. But if you play single-player games, watch films, or do any creative work on the side, the TN panel's colour limitations and narrow viewing angles will frustrate you within a week. Know your use case before you spend money in this bracket.

So let's look at what the spec sheet and real-world owner feedback actually tell us about this monitor, section by section.

The panel carries a rated response time of 0.5ms (MPRT), which is the motion picture response time figure rather than the grey-to-grey measurement. BenQ also specifies a 1ms GtG (grey-to-grey) figure. Adaptive sync is present via AMD FreeSync, with a sync range of 48Hz to 240Hz. The monitor is not G-Sync certified, though it will work with NVIDIA cards over FreeSync on compatible setups. Brightness is rated at 320 cd/m2, and the native contrast ratio sits at 1000:1, which is standard for TN. There is no HDR certification of any meaningful tier here, which is fine given the target use case.

One thing from the spec sheet is the connectivity layout, which is solid for its generation: two HDMI 2.0 ports, one DisplayPort 1.2, and a USB 3.0 hub. The stand is height-adjustable, tiltable, and rotatable, with BenQ's smaller base design that frees up desk space compared to the older XL series stands. The XL Setting to Share feature lets players save and share monitor profiles via a USB stick, which is a genuinely useful tournament feature that competitors haven't really matched.

What TN panels do better than any other technology at this price point is speed. The pixel response characteristics of TN allow for extremely fast transitions, which is why essentially every professional esports tournament monitor you'll see in a broadcast is either a TN or, increasingly, a fast IPS. The XL2540K's 1ms GtG spec is achievable in practice on a TN panel in a way that IPS panels rated at "1ms" via overdrive often are not. Published measurements from display testing outlets have consistently found that TN panels at 240Hz produce lower actual motion blur than IPS alternatives at the same refresh rate, and BenQ's DyAc technology compounds this advantage by acting as a strobed backlight, synchronised with the refresh cycle to sharpen moving images further.

Contrast on TN is typically 1000:1, and the XL2540K matches that. It's not the deep blacks you'd get from a VA panel (which can hit 3000:1 to 5000:1 natively) or the infinite contrast of an OLED, but it's also not the washed-out blacks that some budget TN panels produce. For a brightly lit gaming room, the 1000:1 contrast is perfectly fine. In a dark room, you'll notice blacks look more grey than on a VA or OLED, but that's a panel technology constraint rather than a BenQ-specific failing. Owner reviews don't flag this as a major complaint, which suggests most buyers are aware of the trade-off going in.

The anti-glare coating is a matte finish, which handles ambient light well and avoids the reflections that glossy panels produce. In a well-lit room or near a window, the matte coating is a practical advantage. The trade-off is a slight loss of perceived sharpness and colour vibrancy compared to glossy panels, but for a competitive gaming monitor in a tournament or LAN environment, matte is the correct call. BenQ has been consistent about this across the XL series for good reason.

Brightness uniformity on TN panels is generally decent, and the XL2540K's 320 cd/m2 rated peak brightness is adequate for most indoor environments. It won't punch through bright sunlight the way a 600-nit IPS panel would, but for the indoor gaming scenarios this monitor targets, it's sufficient. Owner reviews don't raise brightness uniformity as a consistent concern, which suggests BenQ's QC on panel selection is reasonable. A small number of reviews mention backlight bleed at the edges, which is typical for any LCD at this price point rather than a specific fault of this model.

The FreeSync implementation covers 48Hz to 240Hz, which is a wide enough range to be practically useful. Low Framerate Compensation (LFC) kicks in below 48Hz, doubling the frame rate signal to maintain smooth output. In practice, if you're running this monitor at 240Hz you're presumably targeting frame rates well above 48, so the lower end of the sync range is less critical. The monitor is not G-Sync certified, but NVIDIA's drivers have supported FreeSync-compatible monitors for several years now via the "G-Sync Compatible" mode, and owner reports suggest it works without significant issues on NVIDIA hardware.

One thing BenQ does well here is the DyAc backlight strobing, which operates independently of adaptive sync. DyAc works by flashing the backlight in sync with the display's refresh cycle, reducing the perceived motion blur that comes from your eyes tracking moving objects across the screen. It's similar in concept to ULMB (Ultra Low Motion Blur) on G-Sync monitors or ELMB on ASUS panels. The key point is that BenQ's implementation has been refined across several generations of the XL series, and owner feedback consistently rates it as one of the better strobing implementations in this class. You cannot run DyAc and FreeSync simultaneously, which is a hardware limitation of strobed backlight technology generally rather than a BenQ-specific shortcut.

Published display measurements from testing outlets that have covered the XL series consistently show that BenQ's overdrive implementation is well-tuned. The "Advanced Motion Accelerator" setting in the OSD provides multiple overdrive levels, and the middle settings generally produce clean transitions without significant overshoot. Owner reviews rarely mention inverse ghosting or trailing artefacts as complaints, which aligns with what the spec sheet and BenQ's track record on overdrive tuning suggest. Compare this to some fast IPS monitors where aggressive overdrive settings create obvious white coronas around moving objects in dark scenes, and the TN advantage becomes clear.

DyAc deserves a separate mention here because it materially changes the motion clarity picture. With DyAc active, the perceived motion blur is substantially reduced compared to running the panel in standard continuous backlight mode, even at 240Hz. The strobing introduces a slight brightness reduction (which is physics: you're turning the backlight off for part of each cycle), and some users are sensitive to the flicker that strobed backlights produce. BenQ includes a DyAc+ mode that pushes the strobing harder for maximum clarity. Most owner reviews that comment on DyAc describe it positively, with a minority noting the brightness trade-off or flicker sensitivity. If you know you're sensitive to backlight flicker, this is worth factoring in.

Factory calibration is not something BenQ advertises for the XL2540K. There is no included calibration report, and the out-of-box colour accuracy is typical for a gaming-focused TN panel rather than a pre-calibrated professional display. Published measurements of the XL series have generally found Delta-E averages in the 2 to 4 range out of the box, which is acceptable for gaming but below the Delta-E less than 2 threshold that colour-critical work demands. Owner reviews don't raise colour accuracy as a concern, largely because the buyer profile for this monitor isn't shopping for colour fidelity.

The OSD includes BenQ's Black eQualizer feature, which lifts shadow detail in dark scenes without blowing out highlights. For competitive gaming, where spotting enemies in dark corners matters more than cinematic shadow rendering, this is a useful tool. It's essentially a gamma curve adjustment that compresses the dark end of the tonal range. Some players run it at moderate settings permanently; others leave it off. It's the kind of feature that sounds gimmicky but has a legitimate use case in the specific context this monitor targets. The Colour Vibrance setting similarly adjusts saturation for players who want more vivid-looking game environments, though it moves away from accurate colour reproduction when pushed hard.

If HDR matters to you at all, this is not the monitor to buy. The VESA DisplayHDR certification tiers start at DisplayHDR 400, which requires 400 nits peak brightness and is widely regarded as the minimum useful HDR tier. Even that tier doesn't produce a dramatic HDR effect without local dimming. For genuine HDR impact you need DisplayHDR 600 or above, ideally with zone dimming or FALD (Full Array Local Dimming). None of that is relevant to the XL2540K's mission, and the owner review base doesn't raise HDR absence as a complaint.

What this means practically is that if you're running HDR in Windows or in game settings, the XL2540K will either ignore the HDR signal or produce a washed-out image. The correct approach is to leave HDR disabled at the OS level when using this monitor. This is a common point of confusion for buyers who are used to HDR-capable screens, but it's a non-issue once you understand the monitor's scope. The XL2540K does SDR gaming exceptionally well. It doesn't do HDR at all, and that's an honest trade-off rather than a hidden flaw.

Peak brightness at 320 cd/m2 is on the moderate side for 2024 standards. IPS panels in the same price bracket often reach 400 to 500 nits, and OLED panels are pushing 800 to 1000 nits peak. For a competitive gaming monitor used indoors, 320 nits is sufficient: you don't need to overpower ambient light the way a laptop screen or an outdoor-facing display does. The anti-glare matte coating helps manage reflections from room lighting, which reduces the effective brightness demand on the panel. Owner reviews don't flag brightness as a limitation in typical use, though a small number of reviews from users in very bright rooms note that the screen can look dim at maximum brightness.

Running DyAc or DyAc+ reduces effective brightness further, since the strobed backlight is off for a portion of each refresh cycle. BenQ doesn't publish the exact brightness reduction figure for DyAc mode, but strobed backlight implementations typically reduce perceived brightness by 20% to 40% depending on the duty cycle. This means that in DyAc+ mode you're likely working with effective brightness in the 200 nit range or below, which in a dark gaming room is still workable but in a bright environment may feel dim. This is before you commit to running DyAc permanently.

The stand provides height adjustment, tilt, rotation (swivel), and pivot (portrait mode rotation). The height adjustment range is generous enough for most sitting positions, and the tilt range covers the typical angles players use. Swivel is useful for sharing the screen or repositioning without moving the base. Portrait mode is available for the minority of players who want a vertical layout, though at 1080p portrait the resolution becomes quite narrow. Build quality on the stand is solid: owner reviews describe it as stable and wobble-free, which matters when you're making fast mouse movements that can vibrate a desk. The stand column has a cable management channel, which keeps the back of the setup tidy.

VESA mounting is supported at the standard 100x100mm pattern, so if you prefer a monitor arm you can remove the stand and mount it cleanly. The total weight of 5.9kg with stand is reasonable for a 24.5-inch panel and won't challenge a quality monitor arm. The OSD controls are physical buttons on the underside of the panel, supplemented by BenQ's S. Switch accessory (sold separately) for quick profile switching. The XL Setting to Share feature, which lets you export and import monitor profiles via USB, is a standout for tournament players who want consistent settings across different setups. It's a small thing but genuinely thoughtful engineering for the target audience.

There is no USB-C port, which is consistent with the XL2540K's positioning as a dedicated gaming display rather than a multi-purpose productivity screen. USB-C with DisplayPort Alt Mode and Power Delivery would be useful for laptop users, but the XL2540K's buyer isn't typically connecting a laptop. The absence of USB-C is not a meaningful gap for the target use case. Similarly, there's no built-in speakers, which is the correct call for a gaming monitor: anyone buying a 240Hz competitive display is using a headset or dedicated audio hardware, not monitor speakers.

The headphone jack on the rear panel is a practical inclusion for players who want to run audio through the monitor's signal chain. The input selection is managed via the OSD, which BenQ has refined over multiple XL generations into a reasonably intuitive system. The Quick Menu feature allows customisation of the OSD shortcuts, so frequently used settings like DyAc mode, Black eQualizer level, and colour profile can be accessed without navigating deep menu trees. Owner reviews describe the OSD as one of the better implementations in the competitive gaming monitor category, which tracks with BenQ's long history in this space.

Against the PG259QN, the XL2540K trades colour quality and viewing angles for BenQ's superior motion blur reduction via DyAc and the XL Setting to Share feature. The PG259QN's IPS panel offers meaningfully better colour coverage and viewing angles, and 360Hz is faster than 240Hz. But the IPS panel's response time characteristics mean that aggressive overdrive is needed to approach TN-level motion clarity, and the ASUS monitor lacks a comparable strobing implementation. For professional esports players who prioritise motion clarity above all else, the XL2540K's DyAc is a genuine differentiator. For players who want a better all-round screen, the IPS alternative is more versatile.

Against the AOC AG251FZ2E, the XL2540K costs more but delivers a better stand, better OSD software, DyAc, and the XL Setting to Share feature. If you're on a tighter budget and don't need the tournament-focused extras, the AOC is a reasonable alternative. But the BenQ's build quality, ergonomics, and motion blur reduction are measurably better, and the price difference reflects real engineering rather than just brand premium.

The limitations are real and worth naming clearly. TN panel colour is noticeably worse than IPS or OLED alternatives. Viewing angles are poor. There's no HDR. The 99% sRGB gamut is fine for gaming but useless for creative work. Brightness at 320 nits is adequate indoors but not impressive. And at the upper mid-range price point, you can buy 1440p IPS monitors at 165Hz or 180Hz that offer a dramatically better all-round experience for the same money, if competitive gaming isn't your primary use case.

Who should buy this: CS2, Valorant, or Apex players who are serious about performance and want the best motion clarity in this price bracket. Players who compete at LAN events and want portable profile settings. Anyone who has already decided that 240Hz TN is the right tool and wants the best-executed version of it.

Who should skip it: anyone who plays single-player games, watches films on their monitor, does photo or video editing, or sits off-centre from their screen. Also skip it if you're gaming at 1440p or above on a capable GPU and want the resolution to match. And honestly, if you're not regularly hitting 200-plus frames per second in your games, a well-specced 165Hz or 180Hz IPS panel in the mid-range bracket will serve you better for less money. The BenQ Zowie XL2540K earns its place in the upper mid-range bracket for the audience it's built for. It just isn't built for everyone, and it doesn't pretend to be.
