AOC 24G4ZR Gaming Monitor Review UK (2026). Tested & Calibrated

You see a monitor listing: 260Hz, 1ms response time, HDR ready. Sounds brilliant. Then you dig deeper and realise half those numbers are technically true but practically meaningless. The “1ms” is measured in a lab under conditions you’ll never replicate. The HDR barely qualifies. I’ve been testing displays for over a decade, and I can tell you this much: what matters isn’t what’s printed on the box, it’s what actually happens when you plug the thing in and use it for real work or gaming. So let’s see if the AOC 24G4ZR Gaming Monitor delivers on its promises or if it’s just another spec sheet that looks better than it performs.

The 260Hz refresh rate is the real story here. This isn’t some overclocked panel running at the edge of stability. It’s a native 260Hz Fast IPS panel from AU Optronics that’s been appearing in several budget gaming monitors lately. I’ve tested this exact panel in other housings, and it’s properly quick.

After about a month of testing, the panel characteristics became clear. The Fast IPS tech here is genuinely fast – response times are competitive with older TN panels, which is impressive for IPS. But it’s still IPS, so you’re getting that familiar greyish black level and noticeable glow in the corners when viewing dark content.

Colour consistency is solid across the screen. No major tinting or brightness variation that I could detect. The panel coating is semi-matte, which handles reflections reasonably well without adding too much grain to the image.

The 260Hz refresh makes a noticeable difference over 144Hz or 165Hz panels, especially in fast-paced shooters. Is it as dramatic as going from 60Hz to 144Hz? No. But if you’re playing competitively, every bit of motion clarity helps. The higher refresh rate gives you more recent frames to react to, reducing the effective latency between what’s happening in the game and what you see on screen.

I tested motion clarity with UFO Test and Blur Busters patterns, then verified in actual games. CS2, Valorant, and Apex Legends all looked sharp during rapid camera movements. There’s some trailing on dark-to-light transitions (typical for IPS), but it’s not enough to impact competitive play.

Input lag measured at 2.1ms, which is excellent. Combined with the 260Hz refresh, the total system latency is about as low as you can get without spending significantly more money.

Let’s be clear: this monitor has no meaningful HDR capability. It accepts an HDR10 signal and tone maps it down to the panel’s limited brightness and contrast. The result looks worse than just using SDR. Don’t buy this for HDR. If you want actual HDR, you need at least DisplayHDR 600 with local dimming, which means spending considerably more.

I tested HDR with several games and the Windows HDR calibration tool. In every case, SDR looked better. The lack of local dimming and limited peak brightness means HDR content just looks washed out. Leave HDR off and use SDR mode.

I spent most of my testing time in CS2 and Valorant, where this monitor makes the most sense. The motion clarity is genuinely impressive. Tracking enemies during rapid strafing or spray transfers is easier than on my reference 165Hz panel. The difference isn’t massive, but it’s there.

For console gaming, the HDMI 2.0 ports limit you to 120Hz at 1080p, which is fine for PS5 and Xbox Series X. You’re not getting the full 260Hz via HDMI, but 120Hz is still a significant upgrade over 60Hz for console players.

Build materials are budget-appropriate plastic, but it doesn’t feel cheap. The bezels are slim on three sides with a slightly thicker bottom bezel. The back panel has a simple geometric pattern that’s inoffensive. Cable management routing is basic but functional.

There are no built-in speakers. Use headphones or external speakers. The 3.5mm audio jack is there for headphone passthrough from your PC.

If you’re considering the Z-Edge 24-inch, understand that you’re getting a 75Hz VA panel. It’s fine for casual gaming and office work, but not in the same performance category as the 24G4ZR. The price difference reflects the capability difference.

For those who want to step up, the Philips Evnia 27-inch 4K offers better image quality and proper HDR, but at a significantly higher price and with a lower refresh rate. Different priorities entirely.

The value proposition is straightforward. If you prioritise refresh rate and response time over image quality, this delivers performance that competes with monitors costing 50-70% more. If you want good contrast, accurate colours, or meaningful HDR, you’ll need to spend considerably more or accept lower refresh rates.

This isn’t a jack-of-all-trades monitor. It’s a specialist tool for competitive gaming. Buy it for that purpose and you’ll be pleased with what you get. Buy it expecting good HDR or cinematic image quality and you’ll be disappointed.
