Best Overall Value
The AOC 25G3ZM/BK sits in an interesting spot in this roundup. It's a 25-inch 240Hz gaming monitor, and that refresh rate matters more than most buyers realise. Out-of-the-box colour accuracy is often poor on budget panels, and a calibrated unit means you're starting from a much better baseline.
IPS technology here gives it a clear advantage over the VA-based gaming monitors in this list when it comes to colour reproduction and viewing angles. If you're gaming but also doing some creative work, editing photos, or just want colours that look right without spending an hour in the OSD menu, this is the one to consider among the best AOC monitors under £100.
240Hz keeps it competitive for fast-paced gaming, and at 25 inches with 1080p resolution you're at a comfortable 88 PPI. Sharper than the 27-inch options, and noticeably crisper than the 32-inch C32G2ZE. The build feels solid, with a well-constructed stand and a chassis that doesn't flex or creak.
The calibrated aspect is the real differentiator here. Most budget monitors need adjustment before they look their best. This one arrives ready to go, which is a genuine time-saver and a mark of quality control that's unusual at this price point. That's why it earns the Best Build Quality badge in this roundup.
It's not the biggest screen, and 25 inches is a slightly awkward size between 24 and 27. But the combination of IPS accuracy, 240Hz speed, and calibrated quality makes it a well-rounded choice.
Pros
- Tested and calibrated out of the box
- IPS panel with accurate colours and wide viewing angles
- 240Hz for competitive gaming
- Solid build quality for the price
- Sharp 88 PPI pixel density
Cons
- 25-inch size is slightly awkward
- IPS brightness may not match VA contrast in dark gaming scenes
- Priced at the top of the sub-£100 bracket

Mid-Range Gaming Pick
A 4K IPS monitor for £99. Read that again. The AOC U27B3A is one of the most surprising entries in this roundup of the best AOC monitors under £100, and it deserves serious attention from anyone who prioritises resolution over refresh rate.
At 3840x2160 on a 27-inch IPS panel, you're looking at 163 PPI. That's genuinely sharp. Text is crisp, images are detailed, and the difference compared to 1080p is immediately obvious. For productivity work, spreadsheets, document editing, coding, or watching 4K content, this is a different class of visual experience compared to everything else in this roundup.
The IPS panel brings accurate colours and wide viewing angles, and 350 cd/m² brightness is the highest in this roundup, which helps the HDR10 implementation feel more convincing than on the VA-based panels. Built-in speakers are a genuine bonus for a monitor at this price, saving you the cost of a separate audio solution.
The compromise is clear: 60Hz. For gaming, that's a hard limit. You won't be running fast-paced titles smoothly, and there's no high refresh rate to fall back on. This is a productivity and media monitor, full stop. But if that's what you need, the value here is remarkable.
The three-side frameless design looks premium, and the HDMI 2.0 plus DisplayPort 1.4 connectivity handles 4K at 60Hz without issue. A genuinely unique option among the best AOC monitors under £100.
Pros
- 4K IPS resolution at an almost unbelievable price
- 163 PPI for sharp, detailed images
- 350 cd/m² brightness, highest in this roundup
- Built-in speakers included
- Three-side frameless design looks premium
Cons
- 60Hz only, not suitable for gaming
- 4ms response time is slower than gaming alternatives
- Requires a capable GPU to drive 4K content

Buying Guide: What to Look For in the Best AOC Monitors Under £100
Shopping for the best AOC monitors under £100 means making some deliberate trade-offs. Here's what actually matters and what the numbers mean in practice.
Panel type: VA vs IPS. VA panels offer deeper blacks and higher contrast ratios, which is great for gaming and watching films. The trade-off is narrower viewing angles and occasional smearing in very dark scenes at lower response times. IPS panels have more accurate colours and wider viewing angles, making them better for productivity, creative work, and shared viewing. At under £100, neither will be perfect, but knowing which matters more to you narrows the choice quickly.
Refresh rate: how much do you actually need? For competitive gaming, higher is better. 240Hz and 280Hz give you a real advantage in fast-paced titles if your GPU can push the frames. For everyday use, 100Hz is a noticeable improvement over 60Hz. 75Hz is fine for basic tasks. Don't pay a premium for 280Hz if you're mainly using the monitor for spreadsheets.
Resolution and screen size together. 1080p on a 24-inch screen looks sharp. On a 32-inch screen it looks softer. If you're sensitive to pixel density, stick to 24 to 27 inches for 1080p. The AOC U27B3A's 4K resolution on 27 inches is the sharpest option in this roundup by a significant margin.
Adaptive sync: FreeSync vs G-Sync. All the gaming monitors in this roundup support AMD FreeSync Premium. If you have an Nvidia GPU, check whether your card supports G-Sync Compatible mode. Most modern Nvidia cards do, and FreeSync monitors will work with variable refresh rate enabled.
Connectivity. Make sure the monitor has the ports your PC or laptop needs. DisplayPort 1.4 handles high refresh rates at 1080p without issue. HDMI 2.0 is fine for 1080p at any refresh rate and 4K at 60Hz. HDMI 1.4 limits you to 1080p at 60Hz, so check carefully if you're buying the 24B3HA2 with an older system.
Brightness. Budget monitors often list 250 to 300 cd/m² brightness. That's adequate in a controlled environment but can struggle in a bright room with windows. If your workspace gets a lot of natural light, prioritise higher brightness specs or consider positioning carefully.
