Acer Nitro ED273 S3 Review UK (2026) - Specs, Gaming Performance & Honest Verdict

You know what actually ruins a high refresh rate monitor? When the pixels can't keep up with the numbers on the box. A monitor that says 165Hz but smears through fast motion is worse than useless, because you've paid for something that actively makes games look worse than your old 60Hz panel did. That's the real test, and it's why the spec sheet alone never tells the whole story.

The Acer Nitro ED273 S3 is a 27-inch curved 1080p gaming monitor with a 165Hz native refresh rate (overclockable to 180Hz), AMD FreeSync Premium, and a 1ms VRB response time claim. It sits in the mid-range bracket, which is competitive territory right now. And with 253 owner reviews averaging ★★★★½ (4.8), there's clearly something going right here. This Acer Nitro ED273 S3 review digs into whether that enthusiasm is justified or whether buyers are just happy to have a big curved screen at this price point.

Short answer: it's a solid buy for 1080p gaming, with some caveats around the response time marketing and HDR that you should absolutely know about before handing over your money. The longer answer is below.

Connectivity is three ports: one HDMI 2.0, one HDMI 1.4, and one DisplayPort 1.2. To hit 165Hz or 180Hz, you'll want to use the DisplayPort connection or the HDMI 2.0 port. The HDMI 1.4 port caps out at lower refresh rates, so plug your PC into the right socket or you'll wonder why you're only getting 60Hz. There's no USB hub, no USB-C, and no built-in speakers. It's a focused gaming panel, not a do-everything workstation display.

The stand offers tilt adjustment only, which is a limitation upfront. No height adjustment, no swivel, no pivot. If you need more flexibility, you'll be looking at a VESA mount (the panel is 100x100mm compatible). The monitor ships with the Acer Nitro ED273 S3 product page listing a 1ms VRB response time and HDR10 support, both of which we'll come back to in detail because they need context.

The trade-off is viewing angles. IPS panels are rated at 178 degrees in both directions and largely deliver on that. VA panels are technically rated similarly but in practice colour and contrast shift more noticeably as you move off-axis. For a single-user gaming setup where you're sitting directly in front of the screen, this is basically irrelevant. If you're showing someone else the screen from the side, or you're using it in a setup where you're not centred, you'll see the shift. The 1500R curve actually helps here by angling the edges of the panel slightly toward you, which partially compensates for the viewing angle weakness.

One thing VA panels are known for is black smearing, sometimes called black level rise or the VA ghosting effect. This happens in dark scenes where dark objects moving against dark backgrounds leave a trail. It's a known characteristic of VA technology, not specific to this monitor, and it's about if you play a lot of dark, fast-paced games like horror titles or space shooters. The ED273 S3's overdrive settings can help reduce this, but there's a balance to strike between reducing smear and introducing overshoot. Owner reviews don't flag this as a major complaint, which suggests Acer's tuning is reasonable, but it's not zero. VA ghosting in dark scenes is something you accept as part of the deal with this panel type, and that's the honest version of events.

That said, the majority of owners are happy with the image quality for gaming, and that makes sense. Games don't require the same pixel-level sharpness as reading a spreadsheet. Motion and colour matter more in gaming, and those are areas where the ED273 S3 holds up well. The VA panel's strong contrast makes colours pop in a way that flat IPS panels at this price don't quite match. Several owner reviews specifically mention how good the picture looks for the money, which is consistent with what you'd expect from a decent VA panel with solid contrast.

The anti-glare matte coating does its job. There's no mirror-finish glossy surface here, so reflections from windows or overhead lights are diffused rather than thrown back in your face. Brightness uniformity is typically decent on VA panels, though some backlight bleed at the edges is common and owners occasionally mention it in reviews. It's rarely severe enough to be distracting in normal use, but if you're the type who notices every imperfection in a black screen, it's worth being aware of. The 250 cd/m2 typical brightness is adequate for most indoor environments, though it won't win any awards in a bright room.

AMD FreeSync Premium is the key sync standard here. FreeSync Premium requires a minimum 120Hz at the native resolution and mandates Low Framerate Compensation (LFC), which means FreeSync stays active even when your frame rate drops well below the monitor's minimum VRR range. That's important because without LFC, if your GPU drops below the sync range, you're back to tearing. FreeSync Premium sorts that out. The AMD FreeSync specification is worth a quick read if you want the full technical breakdown of what Premium actually guarantees over basic FreeSync.

If you're on an Nvidia GPU, the situation is a bit more nuanced. The ED273 S3 isn't G-Sync certified, but many FreeSync monitors work with Nvidia's G-Sync Compatible mode. Whether this specific panel works well with G-Sync Compatible is something Nvidia hasn't officially validated, so you'd be relying on community reports rather than a guarantee. If you're on Team Red, you're sorted. If you're on Nvidia, it may well work fine, but it's not a sure thing in the same way a G-Sync Compatible certified monitor would be. AMD GPU owners are the natural audience for this monitor, and the FreeSync Premium implementation appears to work properly based on owner feedback.

The actual grey-to-grey pixel transition time on a VA panel like this is typically in the 4ms to 8ms range depending on the transition and the overdrive setting. That's not bad, and at 165Hz the frame time is about 6ms anyway, so the panel can keep up. But 1ms GtG it is not. Acer is doing what the whole industry does with VRB numbers, and it's technically not a lie, but it's absolutely designed to look better than it is. The Wikipedia article on display response time gives a clear breakdown of the different ways response time is measured and why the numbers aren't directly comparable.

In practice, the motion performance appears to be genuinely decent for the price. Owner reviews don't report serious ghosting complaints in normal gaming use. The overdrive options in the OSD let you tune the balance between ghosting reduction and overshoot, and the consensus from buyers is that the default or medium overdrive setting works well. Fast-paced shooters and racing games are where this monitor is designed to shine, and the combination of 165Hz plus FreeSync Premium means the experience is smooth when your frame rate is up there. The VA dark-scene ghosting mentioned earlier is the main motion caveat, not general pixel response in bright scenes.

DCI-P3 coverage isn't specified by Acer for this panel, which is typical for budget-to-mid-range VA monitors. VA panels in this class often cover somewhere around 85% to 90% of DCI-P3 as a byproduct of their gamut, but without a published figure from Acer or a published independent measurement, it's not something to bank on. If you're doing colour-critical work like photo editing or video grading, this isn't the monitor for that. The factory calibration is consumer-grade rather than professional-grade, and Delta-E figures aren't published, which tells you everything you need to know about who this monitor is aimed at.

For gaming and general media consumption, the colour output is well-regarded by owners. Several reviews mention vibrant, punchy colours straight out of the box, which is consistent with VA's characteristic of producing saturated, high-contrast images. You may find the default colour temperature slightly warm or slightly cool depending on your preference, and the OSD colour settings give you enough adjustment to sort that out without needing to go near any third-party software. It's not a colour-accurate professional display. It's a gaming monitor that looks good, and for that purpose, it delivers.

What that means in practice: enabling HDR mode in Windows or in games will give you HDR-flagged output, but the visual improvement over a well-calibrated SDR image is minimal to nonexistent. The panel can't get bright enough to deliver the highlights that make HDR actually look different, and there's no local dimming to deepen blacks independently of bright areas. You're essentially getting the HDR label without the HDR experience. This is checkbox HDR, and it's extremely common at this price. The VESA DisplayHDR specification page lays out exactly what each tier requires if you want to understand the gap between HDR10 support and meaningful HDR performance.

The honest advice: leave HDR off on this monitor. Game in SDR, let the VA panel's native contrast do its thing, and you'll get better-looking dark scenes than HDR mode will deliver. The strong 3000:1 native contrast ratio is more useful than the HDR toggle here. Several owners mention this in reviews, noting that the monitor looks better in SDR than with HDR enabled, which is exactly what you'd expect given the brightness limitations. It's not a flaw unique to this monitor. It's just how budget HDR works, and Acer isn't the only brand doing it.

The 250 cd/m2 typical brightness is on the lower side. It's fine for a dim or normally-lit room, and most people don't game with bright sunlight hitting the screen. But if you're in a bright office or near a window, you might find yourself wishing for more headroom. Some monitors in this class hit 300 to 350 cd/m2, which gives more flexibility. The matte anti-glare coating helps manage reflections, but it doesn't compensate for a dim panel in a bright environment. If your gaming setup is in a well-lit space, factor this in.

Brightness uniformity across the panel is typically good on VA panels, better than FALD (full-array local dimming) edge-lit panels that can have obvious brightness gradients. Some owners mention minor backlight bleed in the corners, particularly visible on solid black screens. This is normal for edge-lit VA panels and rarely visible during actual gaming. If you're the kind of person who tests a new monitor with a pure black screen and a torch, you'll probably find something to complain about. If you just play games on it, you'll likely never notice.

The good news is the VESA 100x100mm compatibility means any standard monitor arm will work. VESA arms are cheap and genuinely transform the usability of a monitor with a limited stand. If you're already planning to use an arm, the stand limitation doesn't matter at all. If you want to use the included stand and need height or swivel adjustment, this isn't the right monitor for you, and that's before purchase rather than after.

Build quality is generally described positively in owner reviews. The plastic construction is typical for the price bracket, nothing feels premium, but nothing feels about to fall apart either. The curved panel looks good on a desk, and the relatively slim bezels on three sides keep it looking modern. The base footprint is reasonable, not one of those stands that takes up half your desk. Assembly is straightforward, and owners report it takes about ten minutes to put together. The OSD buttons are on the back-right of the panel, which is standard for this type of monitor and easy enough to navigate once you've found them.

• DisplayPort 1.2: supports 1080p at 165Hz and 180Hz OC
• HDMI 2.0: supports 1080p at 165Hz and 180Hz OC
• HDMI 1.4: limited to lower refresh rates (60Hz at 1080p in most cases)

The HDMI 1.4 port is because it can catch people out. HDMI 2.0 has the bandwidth for 1080p at high refresh rates, but HDMI 1.4 is limited to 10.2 Gbps, which caps 1080p at around 144Hz in practice. If you're connecting a current-gen console or a PC and wondering why you're not getting the full refresh rate, check which HDMI port you're using. Use the HDMI 2.0 or DisplayPort for your primary gaming device.

The lack of a USB hub is a genuine omission for anyone who wants to plug peripherals into the monitor. No USB-C means no laptop connectivity via a single cable. These are the trade-offs you make at this price point. The monitor is built to do one thing well, which is display games at high refresh rates, and it doesn't try to be a docking station on the side. If you need USB passthrough or USB-C, you're looking at a different product category and a higher price.

The AOC C27G2ZE pushes 240Hz at 1080p, which is a significant refresh rate advantage if you're a competitive shooter player who can actually push that many frames. The trade-off is that AOC's overdrive implementation at 240Hz has been noted to produce more overshoot than the ED273 S3's 165Hz setup. More Hz isn't always better if the pixel response can't keep up cleanly. The Samsung Odyssey G5 is the more interesting comparison because it offers 1440p resolution at the same refresh rate, which is a meaningful image quality upgrade. But it typically costs more, and you need a more powerful GPU to drive 1440p at 165Hz compared to 1080p at the same rate. If your GPU is mid-range, 1080p at 165Hz is the smarter choice.

The honest conclusion from the comparison: if you're on an AMD GPU and want a curved 1080p gaming monitor that looks great in dark games and runs smoothly with FreeSync Premium, the ED273 S3 is a strong pick. If you want the absolute highest refresh rate for competitive play and don't care as much about contrast, the AOC's 240Hz IPS panel is worth a look. And if you can stretch the budget and have a GPU powerful enough for 1440p at 165Hz, the Samsung G5 is the better long-term investment for image quality.

The caveats are real but manageable. The 1ms VRB claim is marketing, not a GtG pixel response figure. The HDR is checkbox HDR that you should leave switched off. The stand is tilt-only, which is annoying if you need height adjustment. And 1080p on 27 inches is noticeably softer than 1440p if you sit close. None of these are dealbreakers for the target audience, but they're things you should go in knowing rather than discover after setup.

If you're upgrading from a 60Hz or 75Hz monitor and want something curved and fast for gaming, this is a proper step up and the price makes it accessible. The VA contrast will immediately make dark games look better than whatever IPS panel you're replacing at a similar price. The FreeSync Premium range keeps things smooth across a wide frame rate range, and the 180Hz overclock is a nice bonus if your GPU can use it.

One honest note though: if your budget is tighter and you don't need the curved panel or the 180Hz OC, there are flat 1080p 144Hz IPS monitors available for less that will give you better viewing angles and sharper text for general use. The ED273 S3 earns its price for gaming specifically. For a mixed-use setup where gaming is only part of what you do, a flat IPS at a lower price might actually suit you better. Know what you're buying it for.

Editorial score: 8 out of 10. Strong value for 1080p gaming, honest about its limitations, and backed by an unusually positive owner review base. A confident recommendation for the right buyer.
