For 4 thousand, an excellent buy! Alza discounted a 27″ QHD monitor with a refresh rate of up to 260 Hz

A 27″ QHD monitor with a Fast IPS panel and 240Hz refresh rate is a great buy for four thousand. The AOC Q27G4ZR is now available on Alza with code ALZADNY25 for 3 999 Kč instead of the usual 5 332 Kč. While it’s not a new historical low, but a continuation of last month’s promotion, it’s still a deal you should note if you’re currently considering upgrading your gaming setup.

Quick summary:
✅ Makes sense if you’re looking for a 27″ QHD gaming monitor with a high refresh rate and IPS panel under 4 000 Kč.
⚠️ Consider if you’re concerned about quality HDR (here IPS without local dimming) or want to avoid the risk of backlight bleed on some units.
💡 For 3 999 Kč you get a combination of Fast IPS, 240 Hz (260 Hz after overclocking) and a fully adjustable stand, which competitors don’t offer at this price point.

Why this monitor is interesting

AOC Q27G4ZR targets players with a limited budget who want higher resolution than FullHD and simultaneously a high refresh rate – it boasts a 27″ Fast IPS panel with QuadHD resolution, a native refresh rate of 240 Hz, and the option to overclock to 260 Hz. This is a combination that only recently was offered by monitors in the 7–8 thousand Kč price range, today you can buy it for under 4 000 Kč.

The second reason to look at this model is the price range it falls into. As recently as June 2025, the monitor cost over 6 000 Kč, today it’s available with discount code ALZADNY25 for 3 999 Kč. As we noted above, it had the same price during the last campaign, so while it’s not a price record, Alza still has the best offer on the domestic market.

Key parameters: panel, refresh rate, response time

At the heart of the monitor is a Fast IPS panel with a native refresh rate of 240 Hz, which can be overclocked to 260 Hz. The manufacturer states a response time of 1 ms GtG – in practice, this means significantly less motion blur than with classic IPS panels and an image suitable even for fast-paced titles where reflexes are key. The panel covers 123.6% sRGB and 91.4% Adobe RGB, so colors have enough space even for casual photo editing.

In terms of synchronization, the monitor supports Adaptive-Sync and is G-Sync Compatible, so with both NVIDIA and AMD graphics, you eliminate screen tearing. The VESA DisplayHDR 400 certification is present, but set your expectations realistically – it’s an IPS panel without local dimming, so HDR is more of a formality. This is also confirmed by users themselves, who recommend turning off HDR in reviews. However, a maximum brightness of 400 cd/m² and an anti-reflective surface make the monitor usable even in a well-lit room.

An important note that you will repeatedly encounter in reviews: DisplayPort 1.4 is required to achieve the full 240/260 Hz refresh rate. Via HDMI 2.0, you will only get a maximum of 144 Hz. So, if you want to utilize the full potential of the panel, you must account for a DisplayPort cable (only HDMI is included in the package).

Practical aspects: ports, ergonomics, speakers

Connectivity is standard for this segment – HDMI 2.0 and DisplayPort 1.4, built-in 2× 2 W speakers, Kensington lock. What is noticeably missing here is a USB hub, which some users have pointed out in reviews. If you have many peripherals on your desk, it’s good to consider this beforehand. For wall mounting or an arm, VESA 100×100 is used.

The stand is above average in this price category. It offers height adjustment, tilt, swivel, and pivot – meaning the ability to rotate the monitor 90 degrees vertically, which is useful for working with documents or programming. The base is designed to save space on the desk, so a keyboard can fit underneath it. The weight of 5.32 kg is not extreme for a 27″ display, but if you plan to move the monitor frequently, it’s not among the lightest.

From the perspective of eye health, the monitor features Flicker-Free technology, and in the menu, you’ll find modes for reducing blue light. The warranty is 36 months, which is a pleasant bonus for gaming monitors in this price range and generally standard for AOC.

What users say

On Alza, the AOC Q27G4ZR has a rating of 4.1 out of 5 (35 ratings, 16 user reviews) and 77% of customers recommend it. Positive aspects repeatedly mentioned in reviews include low input latency, sharp motion image, fully adjustable stand, and price/performance ratio. The return rate is low, Alza states 1.27%, and over 1,000 units have been sold.

However, the criticism is significant and worth noting. Several users mention backlight bleed – light leakage in the corners, mainly visible in dark scenes. Some call it “non-negligible IPS glow,” while others write that they don’t see the problem at normal brightness around 20%. The second recurring point is a quiet buzzing from the power supply at 240 Hz on QHD, audible in a quiet room without headphones. The third criticism targets the HDR mode – users agree that HDR has no practical meaning on an IPS panel without local dimming.

It’s worth noting that some critical reviews are based on comparisons with specific alternatives (e.g., the cheaper 24″ AOC Q24G4RE without the same issues). One user described a unit with dead pixels, but such a case is a statistical reality for IPS panels, not a systemic problem with the model.

If this particular model didn’t appeal to you, but you’re looking for a gaming monitor on sale, you can also browse the current Alza Days, where other discounted 27″ and 32″ models continuously appear. Stock levels change quite quickly.

When it doesn’t make sense

If you’re looking for quality HDR for movies and games with a wide dynamic range, this monitor won’t provide the HDR effect – users themselves recommend turning it off. Similarly, if you need a USB hub for peripherals or a monitor with an integrated laptop charger, you’ll be moving up a price class (typically models U27B3A or Q27V5CW).

The second case is when you don’t have a DisplayPort cable or a GPU with DisplayPort – via HDMI 2.0, you’ll only get a maximum of 144 Hz, and the entire advantage of the 240/260 Hz panel will be lost. In such a case, a cheaper IPS monitor with a lower refresh rate, where HDMI won’t be a bottleneck, might make more sense. And if you have very sensitive hearing and will have the computer on in silence, be aware of the risk of audible power supply buzzing at 240 Hz.

Verdict: who it’s worth it for

The AOC Q27G4ZR for 3 999 Kč makes sense for anyone looking for a 27″ QHD gaming monitor with a high refresh rate and a Fast IPS panel at a reasonable price point. For playing fast-paced games, e-sport titles, and general work, it’s a strong compromise – at this price, its main competitors are the 31.5″ AOC Q32V4 (roughly similar price, larger diagonal, but only 165 Hz) and the 25″ 25G4SXU (smaller and faster, cheaper). Conversely, if you’re looking for HDR, a USB hub, or a flawless panel without the slightest hint of backlight bleed, expect a price tag above 6 000 Kč or go straight for OLED.

Is a higher refresh rate or a larger diagonal more important to you for a gaming monitor?
