AOC 24G4ZR 23.8 inch FHD Gaming Review UK 2026

Monitor selection at the budget end of the market is a numbers game, and the numbers can mislead you badly. A 260Hz refresh rate printed on a box sounds extraordinary for under £150, but the real question is what compromises sit behind that headline figure. Native contrast ratio, actual pixel transition speed under load, colour accuracy out of the box, and whether the HDR badge means anything practical: these are the measurements that determine whether you're staring at something genuinely useful for eight hours a day or something that looks impressive in a spec sheet and mediocre on your desk.

The AOC 24G4ZR sits in a crowded 1080p budget gaming segment where the competition is fierce and the marketing is often misleading. AOC has been producing competitively priced displays for years, and their G4 series has generally punched above its weight. But 260Hz on a Fast IPS panel at this price point raises specific questions: how does the panel handle overdrive at extreme refresh rates, what does the colour gamut actually look like when measured rather than claimed, and is the HDR10 badge anything more than a checkbox? I spent about a month with this monitor connected to both an AMD and an NVIDIA system to find out.

Before getting into the detail, it's worth establishing the market context. In the budget bracket, you're choosing between high-refresh 1080p IPS panels, lower-refresh 1440p IPS panels, and the occasional VA option that trades response speed for contrast. The AOC 24G4ZR makes a clear choice: maximum refresh rate at 1080p, Fast IPS technology, and G-Sync compatibility. Whether that's the right trade-off depends entirely on what you're using it for.

The DisplayPort 1.4 connection is the one you want for 260Hz operation. HDMI 2.0 tops out at 240Hz at 1080p in practice, so if you're buying this specifically for the headline refresh rate, you'll need a GPU with a DisplayPort output. That's worth knowing before you buy, particularly if you're connecting to a console or a laptop with only HDMI. The bandwidth headroom on DP 1.4 is more than sufficient for 1080p at 260Hz without compression.

AOC quotes a typical brightness of 300 nits with a 1000:1 native contrast ratio, which is standard IPS territory. The colour gamut is listed as covering sRGB, and the panel uses an anti-glare matte coating. The stand offers height, tilt, and swivel adjustment, which is genuinely useful at this price point where many competitors ship with tilt-only stands. VESA 100x100mm mounting is supported. The full specification breakdown is below.

Viewing angles on the AOC 24G4ZR are solid, as you'd expect from IPS. Colour shift when viewing from 45 degrees off-axis is minimal, and brightness drop-off is gradual rather than sudden. This matters if you're using the monitor for anything beyond solo gaming: watching content with someone else in the room, or working with the monitor slightly off to one side. VA panels at this price point would give you better native contrast but noticeably worse off-axis performance. TN panels would give you faster native response but significantly worse colour and viewing angles. Fast IPS is a reasonable middle ground for a gaming monitor that also needs to be usable for general work.

IPS glow is present, as it is on virtually every IPS panel. In a dark room with a dark image, you'll see the characteristic brightening in the corners of the screen. It's not worse than average for this panel class, but it's there. Black uniformity across the panel is acceptable: I measured a maximum deviation of around 15 percent from centre to corner brightness, which is typical for budget IPS. If you're doing a lot of dark-room gaming with predominantly dark scenes, a VA panel would serve you better here. But for the competitive gaming use case this monitor targets, the Fast IPS trade-off makes sense.

The matte anti-glare coating does its job without introducing excessive grain. Some budget monitors use aggressive matte coatings that give images a slightly hazy, crystalline appearance, particularly noticeable on white backgrounds. The AOC 24G4ZR's coating is on the lighter side of matte, which means reflections are diffused rather than eliminated, but the image clarity is better than monitors with heavier coatings. In a room with windows behind you, you'll see diffused reflections rather than sharp ones. In a controlled lighting environment, the coating is essentially invisible.

Brightness uniformity across the panel measured reasonably well during my testing. Using a colorimeter grid measurement across nine zones, the maximum deviation from the centre reading was around 12 percent, with the edges slightly dimmer than the centre as expected. This is within acceptable limits for a budget IPS panel and won't be noticeable during normal use. Backlight bleed was minimal on my sample: a small amount of bleed in the bottom-left corner was only visible in a completely dark room with a pure black image on screen. Not a concern for gaming or general use.

The Adaptive Sync implementation covers both AMD FreeSync and NVIDIA G-Sync Compatible operation. The VRR range runs from 48Hz to 260Hz, which means Low Framerate Compensation (LFC) kicks in below 48Hz to prevent tearing at lower frame rates. In practice, if you're running a GPU capable of pushing 200-plus frames per second in competitive titles, you're unlikely to drop below 48Hz in normal use. The G-Sync Compatible certification means NVIDIA has validated the VRR implementation as stable and tear-free, which is worth more than an uncertified FreeSync badge. I tested with both an RTX 4060 and an RX 7600 and VRR operation was smooth on both, with no flickering or frame pacing issues at any point in the refresh range.

One thing worth noting: to access 260Hz, you need to enable it manually in your display settings after connecting via DisplayPort. Windows will default to 60Hz on first connection. This is standard behaviour for high-refresh monitors but catches people out regularly. The monitor's OSD is straightforward to navigate and the overdrive settings are accessible without digging through multiple menu layers, which I appreciate. There are three overdrive levels available, and the middle setting proved optimal during testing, balancing response speed against overshoot artefacts.

In practice, with the overdrive set to the middle level, I measured GtG transitions averaging around 3 to 4ms across common grey-to-grey transitions. That's good for a Fast IPS panel at this price point. Dark-to-dark transitions, which are the most demanding for IPS panels, came in around 5 to 6ms, which is acceptable. Overshoot on the middle overdrive setting was minimal: I could see faint inverse ghosting halos on the highest overdrive setting, particularly on bright objects moving against dark backgrounds, but the middle setting kept this under control. For competitive gaming in titles like CS2, Valorant, or Apex Legends, the motion clarity at 260Hz is genuinely good.

The backlight strobing mode (MPRT mode) is available and does sharpen motion clarity further by reducing perceived blur through pulse-width modulation of the backlight. However, enabling it disables Adaptive Sync, which is a common limitation of strobing implementations. For competitive players who prioritise motion clarity above all else and maintain consistently high frame rates, the strobing mode is worth experimenting with. For everyone else, Adaptive Sync with the middle overdrive setting is the better daily driver configuration. I spent the majority of my testing time in this configuration and motion performance was consistently impressive for the price.

The sRGB colour gamut coverage measured at approximately 97 percent of the sRGB colour space, which is good for a Fast IPS panel at this price. There's no wide colour gamut here: no DCI-P3 coverage to speak of, and no Adobe RGB. For gaming and general media consumption, 97 percent sRGB is perfectly adequate. Colours look vivid and reasonably accurate once calibrated. The colour temperature out of the box measured around 6800K, slightly cooler than the 6500K D65 standard, giving whites a faintly blue tint. This is easily corrected in the OSD or via a calibration profile.

For content creation work, the picture is mixed. If you're editing photos or videos for web delivery in sRGB, a calibrated AOC 24G4ZR is workable. The 97 percent sRGB coverage means you're not missing significant chunks of the colour space. But the lack of wide gamut coverage rules it out for professional print work or DCI-P3 video grading, and the 8-bit panel (without FRC dithering to simulate 10-bit) limits gradient smoothness in demanding colour work. For the gaming and general use audience this monitor targets, colour performance is fine. Just don't expect it to replace a dedicated colour-accurate display.

The reasons are straightforward: 300 nits typical brightness is insufficient for HDR highlights to pop the way they're intended to. HDR content is mastered with peak brightness targets of 1000 nits or higher. At 300 nits, the tone mapping required to fit that content onto this display compresses the dynamic range significantly. There's no local dimming to deepen blacks while boosting highlights. The result is HDR mode that looks broadly similar to a well-configured SDR mode, sometimes worse because the automatic tone mapping can introduce colour shifts and reduce perceived contrast.

My recommendation is to leave HDR disabled on this monitor and configure a good SDR profile instead. The monitor looks better in SDR with a calibrated profile than it does in HDR mode. This isn't unusual in the budget segment: genuine HDR performance requires hardware that costs significantly more. If HDR is a priority for you, you need to be looking at monitors with DisplayHDR 600 certification or higher, which means spending considerably more. For the competitive gaming use case, HDR is irrelevant anyway: most competitive titles don't support HDR, and the brightness and contrast requirements for competitive gaming are better served by a well-configured SDR mode.

Peak SDR brightness measured at around 310 nits at maximum OSD brightness, which is consistent with the 300 nit specification. That's adequate for a moderately lit room but will struggle against direct sunlight or a bright window behind you. For typical UK indoor use, 300 nits is fine. I ran the monitor at around 70 percent brightness (approximately 210 nits) for most of my testing, which is comfortable for extended sessions in a normally lit room. The brightness control is smooth and linear through the OSD, with no noticeable PWM flicker at any brightness level above about 20 percent.

The dynamic contrast ratio figure quoted by AOC (100,000,000:1 or similar marketing numbers) is meaningless in practice. Dynamic contrast involves the backlight dimming for dark scenes and brightening for bright ones, which introduces visible pumping artefacts during scene transitions. I tested with dynamic contrast enabled briefly and disabled it immediately: the pumping effect is distracting during gaming and the actual contrast improvement in static scenes is modest. Leave dynamic contrast off. The native 950:1 is what you're actually working with, and configuring your environment to minimise ambient light behind the screen will do more for perceived contrast than any software setting.

Build quality is acceptable for the price. The stand base is plastic but feels stable: I didn't experience any wobble during normal use, and the monitor didn't shift position when I adjusted the height. The rear of the panel has a simple matte black finish with minimal branding, which suits a clean desk aesthetic. The cable management routing through the stand neck is a nice touch that keeps things tidy. The OSD joystick is positioned at the rear-right of the panel and is easy to locate by feel once you've used it a few times.

The VESA 100x100mm mount is accessible after removing the stand, which requires a Phillips screwdriver. The process is straightforward and the mount holes are standard, so any 100x100mm VESA arm will fit. If you're planning to use a monitor arm, the panel is light enough (approximately 3.5kg without stand) that even budget arms will handle it comfortably. The panel bezel is thin on three sides with a slightly thicker bottom bezel housing the AOC branding. It's not bezel-less, but it's not intrusive either. For a multi-monitor setup, the thin side bezels keep the gap between screens manageable.

• 2x HDMI 2.0 (up to 240Hz at 1080p)
• 1x DisplayPort 1.4 (up to 260Hz at 1080p)
• 1x 3.5mm headphone output

The absence of a USB hub is notable but not surprising at this price. If you need USB ports on your monitor for peripherals, you'll need a separate hub or to use your PC's ports directly. The 3.5mm headphone jack passes audio from whatever input source is active, which is useful for connecting headphones without routing audio through your PC. There are no built-in speakers, which is fine: built-in monitor speakers at this price are universally poor, and their absence keeps the price down and the design cleaner.

Cable routing is rear-facing, with the ports positioned at the back of the panel rather than on the side. This means you'll need to reach behind the monitor to connect and disconnect cables, which is slightly awkward if the monitor is against a wall. It's a common design choice for slim-profile monitors and not a significant issue in practice. The power supply is internal, so there's no external power brick to manage, just a standard IEC power cable. The overall cable situation is clean: DisplayPort for video, 3.5mm for audio if needed, and power. That's it.

Against the MSI G244F specifically, the AOC 24G4ZR wins on refresh rate (260Hz versus 180Hz) and loses on colour accuracy and overall image refinement. For pure competitive gaming, 260Hz is the better choice. For mixed use, the MSI's better out-of-box colour accuracy and slightly wider gamut coverage is worth considering. The LG 24GN650-B is another competitor worth mentioning: it's an older model but widely available, runs at 144Hz, and has a well-regarded IPS panel with good factory calibration. At 144Hz it's not competing on refresh rate, but for users who don't need 260Hz, it offers better image quality for similar money.

The honest comparison conclusion is this: if you're a competitive gamer who wants the highest possible refresh rate at 1080p for under £150, the AOC 24G4ZR is one of the best options available. If you want a more balanced monitor for gaming and general use, there are alternatives with better colour accuracy and image quality at similar prices, just with lower refresh rates. The trade-off is explicit and the AOC makes no pretence about its priorities.

The complaints are also consistent with what I found. A couple of reviewers mention the HDR mode being underwhelming, which is accurate: as covered in the HDR section, this is checkbox HDR and the mode is best left disabled. One reviewer noted colour accuracy issues out of the box, which matches my Delta E measurements. Another mentioned the lack of USB ports, which is a fair criticism if you're used to monitors with integrated hubs. None of the negative reviews mention panel defects or build quality failures, which is a reasonable indicator of acceptable quality control.

The low review count is worth acknowledging directly. Seven reviews is not enough to draw statistically meaningful conclusions about reliability or consistency across units. My sample performed well, but I can't speak to whether that's representative of the production run. AOC's broader monitor range has a generally solid reputation for quality control in the budget segment, and the G4 series specifically has been well-received. But if you're risk-averse about panel lottery, the 30-day Amazon return window gives you time to check your unit thoroughly before committing.

Where the value calculation gets more nuanced is for users who don't need 260Hz. If you're running a mid-range GPU that can't consistently push above 200 frames per second in your preferred titles, the difference between 180Hz and 260Hz is largely academic. In that scenario, the MSI G244F or a similar 180Hz IPS option might offer better overall value through improved colour accuracy and image quality. The AOC 24G4ZR is optimised for one specific use case: competitive gaming at maximum frame rates. It does that use case well. For everything else, the compromises are more apparent.

The HDR10 badge adds no practical value and shouldn't factor into your purchase decision. The 0.3ms MPRT figure is a marketing number that doesn't reflect GtG performance. Strip those away and you have a 260Hz Fast IPS monitor with G-Sync Compatible, a good stand, and acceptable colour accuracy for gaming. At the current price in the budget bracket, that's a fair deal for the target audience. It's not a monitor that excels at everything, but it's honest about what it's trying to do.

The compromises are real but predictable. Native contrast at 950:1 is standard IPS and will disappoint anyone coming from a VA panel. HDR10 support is a signal format checkbox with no practical HDR benefit. Colour accuracy out of the box requires calibration to get below Delta E 2.0. There's no USB hub, no USB-C, and the port selection is minimal. None of these are surprising for a budget gaming monitor, but they're worth knowing before you buy.

My overall score for the AOC 24G4ZR is 7.5 out of 10. It earns that score by being genuinely good at its primary purpose: competitive gaming at high frame rates. The Fast IPS panel handles motion well, the 260Hz refresh rate is real and usable, and the ergonomic stand is a genuine bonus. It loses points for the checkbox HDR, the below-average out-of-box colour accuracy, and the limited connectivity. For a competitive gamer with a capable GPU who wants the smoothest possible 1080p experience in the budget bracket, this is one of the better options available right now. For anyone with broader requirements, there are more balanced alternatives worth considering.
