AOC has released two high-refresh IPS gaming monitors targeting different needs. The first is aimed at those who prefer clearer motion, offering up to 320Hz refresh rate at an easier to run 1440p resolution, while the second is meant for those who require a large, 32in format and a higher 4K resolution. Both feature great specs for their price, making them prime choices for any build.
Q27G4SRU
Starting with the Q27G4SRU, we have an option suited for competitive players who can’t or are unwilling to pay the exorbitant prices of 500Hz OLEDs. It offers QHD (2560×1440) resolution at 320Hz, marking an acceptable compromise between image detail and speed. Its 27in size is also right where you want it to be at 110.84 PPI (pixels per inch) – not large enough to affect image sharpness, and not small enough to impact your competitiveness (targets small and hard to hit).
At the same time, QHD 320Hz is an easier combo to drive on current hardware, where even mid-range GPUs can pull their weight as long as you don’t max out those graphics. The comfortable step up from the 144Hz and 240Hz solutions should provide a noticeable reduction in blur during intense camera movement. Understandably, this won’t be anywhere near the capabilities of an OLED monitor, but it won’t be as expensive either.
The remaining specs are typical of IPS-type panels, including 1ms GtG response time, 450nits of peak brightness, and up to 136.9% sRGB / 93.7% DCI-P3 colour gamut coverage. AOC also advertises DisplayHDR 400 certification, which should give supported content a little punch. Just don’t expect it to blow you away.
Connectivity is covered by two HDMI 2.1 ports plus one DisplayPort 1.4, providing ample bandwidth to handle modern consoles, with two 2W speakers conveniently placed to project their audio. Lastly, a four-port USB hub is also handy, enabling easy peripheral installation.
U32G4U
The U32G4U, on the other hand, focuses on image quality and versatility, combining a sharp 4K (3840×2160) resolution with dual-refresh technology. This means that you get to choose between 4K at 160Hz or FHD (1080p) at 320Hz, depending on the content you intend to consume at any given moment. Want to try the latest ray-traced game? 160Hz is fast enough even for modern GPUs. Received a friend invite for the latest competitive shooter? Switch to FHD 320Hz and track every enemy movement with great clarity.
Despite being larger than the Q27G4SRU, the combination of the 32in size and 4K resolution results in a sharper 139.87 PPI presentation. A fantastic pairing to any modern console, taking advantage of their maximum resolution and frame rate outputs without compromise. This also makes it a strong productivity display, thanks to the increased screen space and PiP/PbP modes, handy for multitasking. To put it simply, you get the same high refresh as its sibling, when needed, plus a comfortable size and resolution for daily use.
Once more, we find IPS’s typical 1ms GtG response time, 1,000:1 contrast, and 450nits peak brightness, granting it the DisplayHDR 400 certification. Both sRGB and HDR content should look vibrant, with a reported 129.3% coverage of sRGB and 93.7% coverage of DCI-P3 gamut. Lastly, connectivity is managed by two HDMI 2.1 ports, one DisplayPort 1.4, plus a four-port USB hub.
The AOC Gaming Q27G4SRU and U32G4U will be available from mid-October 2025 at £249.99 and £339.99, respectively, backed by a three-year warranty. Both are extremely competitive price-wise, sitting among the cheapest monitors with such specs.
