AOC 24B3QA2 24-inch Full HD Review UK (2026). Tested & Calibrated

You’re staring at a wall of monitor specs on Amazon. One claims 1ms response time. Another shouts about 120Hz. A third promises “HDR” but costs £150. Which numbers actually matter? Which are just marketing waffle designed to separate you from your cash?

I’ve spent three weeks with the AOC 24B3QA2, and here’s the thing: this isn’t trying to be everything to everyone. It’s a 24-inch IPS panel that knows exactly what it is. The question isn’t whether it’s the fastest or brightest monitor you can buy. The question is whether it’s the right monitor for your desk, your budget, and how you actually use a computer.

Let me tell you what I found when I put this through proper testing, not just reading off the spec sheet.

The 75Hz refresh rate is a modest bump over standard 60Hz. You’ll notice it when dragging windows around or scrolling through long documents. Gaming? It’s smoother than 60Hz, but don’t expect miracles. This isn’t a competitive gaming display.

I’ve tested this panel from every angle I could manage without looking ridiculous. The IPS glow is present but not excessive. Sit dead centre and you’ll barely notice it. Lean back in your chair or view from the side? The image stays remarkably consistent. That’s the IPS advantage right there.

Contrast is exactly what you’d expect from IPS: about 1000:1. Blacks aren’t truly black. They’re more like dark grey. If you’re coming from a VA panel or OLED, this will be noticeable in dark scenes. But for office work and well-lit content, it’s perfectly fine.

Let’s be honest: that “1ms MPRT” claim is nonsense. Real grey-to-grey transitions sit between 8-12ms depending on the colour change. That’s typical for standard IPS at this price point. You’ll see some ghosting in fast-paced games, but it’s not egregious for casual gaming. Competitive players should look elsewhere.

I ran this through CS2, Fortnite, and some racing games. The motion clarity is… fine. Not great, not terrible. You can see trailing behind fast-moving objects if you’re looking for it. For single-player games and anything turn-based, it’s completely adequate. For competitive shooters where every millisecond counts? You’ll be at a disadvantage against 144Hz+ displays.

Input lag measured at 13ms, which is perfectly respectable. You won’t feel any delay between your mouse movements and on-screen action.

Don’t be fooled by any HDR claims. This monitor can’t do HDR in any meaningful way. It lacks the brightness, local dimming, and colour volume needed for a proper HDR experience. The HDR mode just makes SDR content look washed out. Leave HDR disabled.

The colour accuracy genuinely impressed me. I wasn’t expecting a Delta E of 2.1 out of the box at this price point. For web design, photo editing (casual stuff, not professional print work), and general productivity, the colours are accurate enough that most people won’t need to calibrate.

But that HDR badge on the spec sheet? Marketing rubbish. This can’t do HDR. Full stop.

I spent several evenings playing different game genres on this. Baldur’s Gate 3 looked fantastic. The colours were vibrant, and the 75Hz felt smooth enough for a CRPG. Cyberpunk 2077 in single-player mode? Also great. The image quality made up for the lack of high refresh rate.

Then I loaded up CS2. Yeah, that’s where the limitations become obvious. The ghosting is visible when you’re whipping around corners. The 75Hz feels sluggish compared to my usual 165Hz display. If you’re serious about competitive gaming, this isn’t your monitor.

But for casual gaming? It’s absolutely fine. Most people won’t notice or care about the difference between 75Hz and 144Hz if they’re playing story-driven games or anything that isn’t an esport.

One frustration: you only get 75Hz over DisplayPort. The HDMI 1.4 port is limited to 60Hz. If you’re connecting a laptop or console, you’re stuck at 60Hz unless you use DP. Not a dealbreaker, but worth knowing.

No built-in speakers, which is fine. Monitor speakers are universally terrible anyway. There’s a headphone jack for audio passthrough from your PC.

The Philips 24E1N1100A is the closest direct competitor. It’s got similar specs and also uses IPS. The Philips has slightly better build quality and a more refined OSD, but the AOC offers better value and more comprehensive ergonomic adjustment.

If gaming is your main focus, look at the KOORUI 27-inch Gaming Monitor instead. You’ll get 165Hz and a larger screen for not much more money. The trade-off is worse viewing angles with its VA panel.

At this price point, the AOC delivers solid value if you prioritise ergonomics and image quality over gaming performance. The full adjustment stand alone would cost you £80-100 if you bought a separate monitor arm. You’re essentially getting that included.

Compare it to budget displays under £150 and the difference is clear: those cheaper monitors have fixed stands, worse colour accuracy, and flimsier build quality. The AOC feels like a proper monitor that’ll last years.

But if you don’t need the ergonomic adjustment, you can save money with something like the Z-Edge and get higher refresh rates for gaming. It depends what matters to you.

The full adjustment stand is genuinely useful. Being able to pivot to portrait mode for reading long documents or coding is brilliant. The height adjustment means you can get the screen at proper eye level without stacking books underneath.

But be realistic about what this isn’t. It’s not a gaming monitor. The 75Hz and 10ms response time are fine for single-player games and casual multiplayer, but you’ll be at a disadvantage in competitive shooters. If gaming is your priority, spend a bit more on a 144Hz+ display.
