Acer Nitro KG242Y Gaming Monitor Review UK 2026

Your monitor is the one component you interact with every single second you're at your desk. Not your GPU, not your CPU. The monitor. So when someone asks whether a budget 1080p IPS panel is worth picking up for under £100, that's not a trivial question. It matters more than most people give it credit for.

The Acer Nitro KG242YGbmipfx 24 inch Gaming Monitor sits firmly in the budget bracket, and the verdict is this: it's a solid, no-nonsense screen for casual gaming and everyday use, but it's not going to blow anyone away. At this price point, you're getting a decent IPS panel with 165Hz capability (though listed at 120Hz in the Amazon highlights, more on that below), AdaptiveSync, and a port selection that covers most use cases. What you're not getting is anything close to the colour depth, contrast, or motion clarity that a mid-range or premium panel delivers. Know that going in, and this makes a lot of sense. Go in expecting miracles, and you'll be disappointed.

Owner reviews back this up. With a ★★★★☆ (4.1) average across nine reviews, the picture that emerges is of a screen that does what it says on the tin. People like the image quality for the money. A few grumble about the stand. Nobody's raving about HDR, because there isn't any worth talking about. That's the honest shape of this product, and the rest of this review will fill in the detail.

Brightness is rated at 250 nits, which is modest but workable in a typical indoor environment. The 99% sRGB colour coverage is a genuine highlight for this price bracket, and the connectivity is surprisingly complete: DisplayPort 1.2, HDMI 1.4, VGA, and an audio output. There are also two 2W built-in speakers, which are fine for basic use but nobody's going to be writing home about them. The stand offers 30 degrees of tilt adjustment, and VESA mounting is supported for those who want to put it on an arm.

One thing to be clear about: the 1ms figure in the product name is almost certainly an MPRT (Moving Picture Response Time) marketing stat, not a real grey-to-grey pixel transition measurement. The actual GtG spec of 4ms is what matters for gaming, and that's a reasonable number for an IPS panel. Don't let the "1ms" in the name fool you into thinking this is a TN-speed panel. It isn't, and that's not necessarily a bad thing.

For the money, getting an IPS panel here is genuinely a good call by Acer. Budget monitors used to default to TN almost universally. TN is faster in raw pixel response, but the colour accuracy and viewing angles are poor enough that you notice it constantly. An IPS panel at this price point means the image looks decent from a wide range of seating positions, and colours are reasonably faithful to what they're supposed to be. If you share a desk with someone who sometimes glances at your screen, or if you watch content from slightly off-axis, you'll appreciate the IPS choice.

IPS glow is a real thing though, and about before you buy. It's that characteristic brightening you see in the corners of IPS panels when displaying dark content. It's inherent to the panel technology, not a defect, and on a budget IPS it can be more pronounced than on premium panels. Owner reviews don't flag this as a major complaint, which suggests the panel Acer has sourced is reasonably well-behaved in this regard. But if you're playing a lot of dark horror games or watching films in a pitch-black room, you'll notice it. VA panels handle dark scenes better. OLED handles them best of all, but you're not getting OLED anywhere near this price bracket.

The matte anti-glare coating is standard for monitors in this category and means you can use it in rooms with windows without the screen turning into a mirror. Matte coatings do add a very slight texture to the image compared to glossy panels, which can make colours look marginally less vivid, but the practical benefit of reduced reflections in real-world rooms far outweighs any minor visual softening. Given this is a budget monitor likely to end up in all sorts of lighting conditions, the matte coating is the right call.

Brightness at 250 nits is the one spec that gives me pause. It's fine for normal indoor use, but it's not going to cut through strong ambient light particularly well. If your desk gets direct sunlight in the afternoon, you might find yourself squinting. Most office and bedroom setups will be absolutely fine, but Premium monitors at higher price points regularly hit 400 to 600 nits, and the difference in bright rooms is real. For the price, 250 nits is acceptable. Just don't put this monitor in front of a sun-facing window and expect it to fight back.

The Amazon listing highlights quote 120Hz, which is a bit confusing given the verified spec says 165Hz. This discrepancy might be down to the monitor defaulting to 120Hz out of the box over HDMI 1.4 (which has bandwidth limitations at 1080p that can cap some monitors), with 165Hz requiring a DisplayPort connection. This is a common situation with budget monitors. If you want the full 165Hz, plug in via DisplayPort 1.2 rather than HDMI. before you assume you're not getting what you paid for.

VESA AdaptiveSync is the variable refresh rate technology here. This is the open standard that sits underneath both AMD FreeSync and, in some implementations, NVIDIA G-Sync Compatible. What it means in practice is that the monitor's refresh rate syncs dynamically to your GPU's frame output, eliminating screen tearing without the input lag penalty of V-Sync. For a budget gaming monitor, having AdaptiveSync is a proper win. You're not going to get G-Sync hardware certification at this price, but AdaptiveSync covers the core use case well. Check your GPU's compatibility, but if you're on a modern AMD or NVIDIA card, you're almost certainly going to benefit from this.

Four milliseconds GtG is a solid result for an IPS panel. Budget IPS monitors used to struggle to get below 8ms GtG in real-world conditions, and even today you'll find plenty of IPS screens in this price range that measure closer to 6 to 8ms in practice. Published measurements from display testing suggest that budget IPS panels rated at 4ms GtG typically land somewhere between 4ms and 7ms depending on the overdrive setting used. The response time trade-off with IPS is well documented: push overdrive too hard and you get inverse ghosting (a bright halo trailing moving objects), back it off and you get more blur. Acer's overdrive implementation on the KG2 series has generally been rated as acceptable by owners, without significant complaints about ghosting.

For fast-paced gaming, 4ms GtG at 165Hz is workable. Competitive FPS players at the highest level will prefer a TN or fast-IPS panel hitting 1ms GtG or below, but for most gamers playing at this refresh rate, the difference is subtle. What you're more likely to notice is the improvement from high refresh rate itself rather than any limitation in pixel response. Racing games, platformers, shooters at a casual to moderate level: all fine. If you're grinding ranked in Valorant at a serious level and every millisecond counts, you'd want to spend more. For everyone else, this is absolutely good enough.

Factory calibration on budget monitors is rarely exceptional. You're unlikely to get a Delta-E below 2 out of the box (Delta-E is the measurement of colour accuracy deviation, where below 2 is considered good for colour-critical work). Most budget IPS panels ship with a Delta-E somewhere between 3 and 6, which is visible to a trained eye but perfectly fine for gaming and general use. The 99% sRGB coverage means the raw gamut is there; it's the factory calibration that determines how accurately those colours are actually rendered. Owners haven't reported obviously skewed colours or major white balance issues, which suggests Acer's factory tuning is at least passable.

For content creation, this monitor is a reasonable starting point but not a professional tool. Photo editors and video colourists need Delta-E below 2, ideally below 1, and a wider DCI-P3 gamut for modern HDR content workflows. The KG242YGbmipfx doesn't claim DCI-P3 coverage, and the 250 nit brightness limits its usefulness for HDR grading. But if you're doing light photo editing, graphic design for web, or general creative work alongside gaming, the 99% sRGB coverage means your colours are in the right ballpark. Just don't rely on it for professional print work.

What this means in practice is that if you enable HDR in Windows or in a game on this monitor, you'll likely end up with washed-out, dim-looking images rather than the punchy, high-contrast HDR experience you're hoping for. Some monitors at this price tier technically accept an HDR signal but can't do anything useful with it. The honest advice is: leave HDR off on this monitor. Use it in SDR, where the 99% sRGB coverage and IPS panel will give you a genuinely good-looking image.

Real HDR, the kind that actually looks different and better, needs local dimming, high peak brightness (600 nits minimum for a convincing experience, 1000 nits for proper highlights), and a wide colour gamut covering DCI-P3. You're not getting any of that at this price point from any manufacturer. Budget monitors and real HDR don't mix. If HDR is important to you, you need to spend significantly more, and even then you're looking at edge-lit local dimming rather than full-array, until you get into mini-LED territory. Accept this monitor for what it is: an excellent SDR display for the money.

The 250 nit peak brightness is enough for most typical indoor environments. Sitting in a normally lit office or bedroom, the image will look bright and clear. The concern is environments with a lot of ambient light, particularly direct sunlight. At 250 nits, this monitor won't win that fight. Pull the blinds or position the monitor away from direct light sources and you'll be fine. Most gaming setups are already doing this anyway.

Brightness uniformity is something budget panels occasionally struggle with, where the backlight is noticeably brighter in certain areas of the screen. Owner reviews for this monitor don't flag any egregious uniformity issues, which is encouraging. Minor variation across the panel is normal and expected at this price. What you don't want is a significant hot spot or a corner that's visibly dimmer than the rest. Based on the owner feedback available, this panel seems to avoid the worst uniformity problems, though individual unit variation is always a factor with budget displays.

The good news is that VESA mounting is supported, which means a third-party monitor arm is a straightforward upgrade path. A decent monitor arm costs around £20 to £40 and transforms the ergonomic situation completely, giving you full height, tilt, swivel, and extension adjustment. If you're planning to use this monitor long-term, it's worth factoring that into your budget. The VESA mount support is a genuine plus point on a monitor at this price; not all budget screens include it.

Build quality is what you'd expect from a budget Acer product: functional plastic construction that doesn't feel premium but doesn't feel like it's going to fall apart either. The bezel is relatively thin on three sides, which keeps the footprint compact and looks reasonably modern. Owner reviews don't report significant build quality complaints, which is reassuring. The base footprint is compact enough for smaller desks, which is a practical win. Overall, the build does the job. It's not a premium product and it doesn't pretend to be.

• DisplayPort 1.2: The primary connection for gaming. Use this for 165Hz at 1080p. DisplayPort 1.2 has more than enough bandwidth for 1080p at high refresh rates.
• HDMI 1.4: Good for consoles, laptops, and secondary devices. HDMI 1.4 supports 1080p at up to 120Hz, so console gaming at 120Hz is possible on compatible devices. Note that PlayStation 5 and Xbox Series X both output 1080p at 120Hz over HDMI, so this is a relevant feature for console gamers.
• VGA: Legacy connection for older hardware. It's there if you need it, which is more than many modern monitors offer.
• Audio Out: Useful for plugging in headphones or external speakers, particularly if your PC doesn't have a dedicated audio output or if you want to route audio through the monitor.

What's missing is USB-C and a USB hub, but those are features you'd only expect at significantly higher price points. There's no USB-C power delivery, no built-in KVM switching, no Thunderbolt. For a budget gaming monitor, none of that is a reasonable expectation. The port selection that's here is practical and complete for the target use case. The inclusion of VGA is a nice touch for anyone connecting older hardware, a legacy laptop, or a work machine that only has VGA output.

The 2W speakers are there and they work. They're not going to replace a decent headset or even a cheap speaker set. But for the occasional video call, a YouTube video while you're eating lunch, or background music at low volume, they do the job. Don't expect bass. Don't expect volume. Expect "functional for basic use" and you won't be let down.

Where the Acer KG242YGbmipfx has an edge is the 165Hz refresh rate (if the verified spec is accurate and achievable via DisplayPort), the 99% sRGB coverage claim, and the inclusion of VGA for legacy connectivity. The AOC 24G2 tops out at 144Hz and doesn't always claim 99% sRGB. So on paper, the Acer offers slightly more headroom at the top end of the refresh rate range.

The honest truth is that at this price tier, the differences between competing monitors are small enough that the one you can actually get at the best price on the day you're buying is often the right choice. All of these monitors are budget IPS panels with similar real-world performance. The Acer's 99% sRGB and 165Hz are genuine differentiators, but they're not so dramatic that they make the competition irrelevant. If the Acer is priced competitively when you're shopping, it's a solid pick. If the AOC or LG is cheaper that week, those are equally valid choices.

The weaknesses are real but predictable for the price. The stand is tilt-only, which is frustrating for ergonomics but fixable with a cheap VESA arm. The 250 nit brightness is adequate but not impressive. There's no meaningful HDR. The native contrast is IPS-typical, meaning dark scenes look grey rather than black. None of these are surprises, and none of them are unique to this monitor. They're just the honest trade-offs of buying in the budget bracket.

Who is this for? Students, first-time PC builders, people upgrading from a TV or an old 60Hz monitor, console gamers who want a proper PC-style display without spending big, and anyone who needs a second monitor for a dual-screen setup. It's also a decent shout for office use where you want something better than a generic business monitor but don't need professional colour accuracy.

Who should skip it? Competitive FPS players who need sub-2ms GtG response times and are serious about ranked play. Anyone who watches a lot of HDR content and wants it to actually look good. People who do professional colour grading or print design work. And anyone who sits in a very bright room with direct sunlight on the screen, where 250 nits will feel limiting.

One honest note: if you're primarily using this monitor for office work, spreadsheets, and the occasional casual game, you don't need 165Hz and you don't need AdaptiveSync. A basic 1080p IPS monitor at a lower price point would serve you just as well and save you a few quid. The gaming-specific features here only pay off if you're actually gaming on it regularly. If you are, the Acer KG242YGbmipfx earns its place in the budget gaming monitor conversation. If you're not, there are cheaper screens that do the non-gaming job equally well.

Overall score: 7.5 out of 10. Strong for the money, honest about its limitations, and a sensible buy for the right user.
