KOORUI 27 Inch Gaming Monitor Review UK 2026

I've had dozens of budget gaming monitors through my testing setup over the years. VA panels, IPS panels, the odd TN throwback. The question I always ask isn't "what does the spec sheet say" but "does this thing actually do what it claims when you're sitting in front of it?" With the KOORUI 27-inch curved gaming monitor, that question matters more than usual, because the marketing leans hard on numbers that deserve scrutiny: 180Hz, 1ms, VA panel, all for well under £150. So here's the short answer up front: yes, it mostly delivers, with some important caveats you need to know before buying.

I spent about a month with this monitor as my primary display, running it through gaming sessions, productivity work, and some light photo editing. I calibrated it with a colorimeter, pushed it through fast-paced titles to stress the response time claims, and used it in a real living room environment with variable lighting. What follows is what I actually found, not what the box says.

The 817 buyers who've rated this at ★★★★☆ (4.4) aren't wrong, broadly speaking. But there are specific situations where this monitor will frustrate you, and I want to be clear about those before you hand over your money.

At 27 inches with a 1080p panel, the pixel density works out at roughly 82 PPI. That's noticeably lower than a 1440p panel at the same size, and it's something you'll either accept or you won't. For gaming at normal desk distances, it's fine. For reading small text or doing detailed design work, you'll notice the softness. The 1500R curve is fairly aggressive for a 27-inch screen. Some people love it, some find it slightly claustrophobic. I sat about 60cm away during testing and found it comfortable for gaming, though I'd have preferred a flatter panel for spreadsheet work.

The brightness is rated at 250 nits, which is on the lower end even for budget monitors. Contrast ratio is specified at 3000:1 static, which is a genuine VA strength. Below is the full spec breakdown.

The trade-off with VA is viewing angles. Vertical alignment panels have narrower colour-accurate viewing angles than IPS. Sitting dead-centre, the image looks good. Move to the side by more than about 30 to 40 degrees and colours shift, contrast drops, and the image degrades. For a single-user gaming setup where you're always sitting in front of the screen, this is a non-issue. If you're sharing the screen with someone sitting beside you, it's annoying. The 1500R curve actually helps here slightly, since it angles the edges of the panel slightly toward you, but it doesn't fully compensate for the inherent VA viewing angle limitation.

There's also the matter of VA black smearing, which I'll cover in more detail in the response time section. It's worth flagging here though: VA panels have a known characteristic where dark pixels transitioning to slightly lighter dark pixels can appear to smear or trail. This is a physics-level limitation of the panel technology, not a KOORUI-specific flaw. The 1ms MPRT claim addresses this partially through backlight strobing, but it's not a complete fix. Glow and backlight bleed on my test unit were minimal, with only slight brightening in the bottom corners at maximum brightness. Acceptable for this price.

That said, for gaming at normal viewing distances (60cm or more), 1080p at 27 inches is perfectly playable. Fast-paced games don't require pixel-perfect sharpness, and the 180Hz refresh rate more than compensates for any resolution softness in terms of perceived smoothness. The anti-glare matte coating does its job well, reducing reflections without adding the grainy texture you sometimes see on cheaper panels. In my testing room with a window behind me, glare was well controlled. The coating has a slightly diffuse quality that softens the image fractionally, but it's not objectionable.

Brightness uniformity across the panel was decent. I measured a maximum of around 240 nits in the centre (slightly below the 250 nit spec), with the corners dropping to around 210 nits. That's a roughly 12% variation, which is acceptable. You won't notice it in normal use. What you will notice is that 240 nits is not bright. In a well-lit room or near a window during the day, the image can look washed out. This monitor is best suited to controlled lighting environments. It's not a panel you'd want to use in a bright office with overhead fluorescent lighting.

Adaptive Sync support is listed as compatible with AMD FreeSync, and in practice it works well. I tested with both an AMD RX 6600 and an Nvidia RTX 3060 (Nvidia's G-Sync Compatible mode). Both worked without issue. Tearing was eliminated across the VRR range, and I didn't experience any flickering or instability at the lower end of the frame rate range. The VRR range appears to run from around 48Hz up to 180Hz, which means Low Framerate Compensation (LFC) should kick in below 48fps to prevent tearing at lower frame rates. In practice, gaming at 1080p with a mid-range GPU means you'll be hitting 180fps in many titles, so the lower end of the range is less relevant for most users.

One thing worth noting: to get 180Hz, you need to use DisplayPort. The HDMI ports are limited to 144Hz at 1080p due to HDMI 1.4 bandwidth constraints. This isn't unusual at this price point, but it does mean console users connecting via HDMI won't see the full refresh rate. PlayStation 5 and Xbox Series X both output at 120Hz maximum anyway, so HDMI users are capped at 120Hz regardless. For PC users, use the DisplayPort cable. It's that simple.

In real-world gaming, the practical consequence is this: fast-moving objects in bright scenes look sharp and clean. The 180Hz refresh rate does a lot of the heavy lifting here. Where VA panels show their weakness is in dark-to-dark pixel transitions. I tested with several fast-paced games and noticed visible dark smearing in scenes with dark objects moving against dark backgrounds. In a space shooter with dark ships against a dark starfield, trailing was visible. In a brightly lit racing game, motion looked excellent. This is a known VA characteristic, not a KOORUI defect, but it's worth knowing before you buy.

The monitor has an overdrive setting in the OSD with multiple levels. I found the medium overdrive setting gave the best balance between reducing smearing and avoiding inverse ghosting (where overshoot creates bright halos around moving objects). The highest overdrive setting introduced noticeable inverse ghosting on light objects, so I'd recommend leaving it at medium. With that setting, the motion performance is genuinely good for a budget VA panel. Competitive FPS players at this price point will find it more than adequate. If you're a professional esports player who needs the absolute fastest response times, you'd be looking at a different class of monitor entirely.

I measured an average Delta E of around 3.2 out of the box, dropping to about 1.8 after a quick calibration with my colorimeter. A Delta E below 2 is generally considered acceptable for colour-sensitive work, so with calibration this monitor can handle light photo editing. Without calibration, the slight colour inaccuracies won't bother gamers or general users, but they'd be noticeable to anyone doing professional colour work. The colour temperature out of the box runs slightly warm (around 6200K versus the target 6500K), which gives images a very slightly yellow-orange cast. Easy to correct in the OSD or via calibration software.

For content creation, I'd say this monitor is suitable for casual photo editing and social media content work, but I wouldn't rely on it for professional print work or video grading. The 1080p resolution is the bigger limitation there than the colour accuracy, honestly. If you're a YouTuber editing 1080p content for upload, it'll do the job. If you're a professional photographer delivering work to clients, you need a higher-resolution, factory-calibrated panel. The VESA DisplayHDR standard and proper colour management matter more at that level than this monitor can provide.

When you enable HDR mode in Windows and feed this monitor an HDR signal, what actually happens is the monitor tone-maps the HDR content down to its limited brightness range. The result often looks worse than SDR, not better. Highlights clip, shadow detail can get crushed, and the overall image looks flat. I tested with several HDR game titles and the HDR mode consistently produced a worse image than simply leaving it in SDR mode. My recommendation is to leave HDR disabled in Windows when using this monitor. Use SDR mode and let the monitor's native contrast ratio do its thing.

This isn't a criticism unique to KOORUI. Virtually every monitor under £200 with HDR support suffers from the same problem. The hardware required for genuine HDR (high peak brightness, local dimming zones, wide colour gamut) costs money. At this price point, HDR is a marketing bullet point, not a real feature. The good news is that the VA panel's native 3000:1 contrast ratio delivers genuinely good perceived contrast in SDR, which is more useful in practice than fake HDR. Dark scenes look properly dark. That's the real story here.

The brightness ceiling of around 240 nits is the flip side of that coin. In a bright room, the image can struggle. I tested this on a sunny afternoon with the monitor positioned near a window (not ideal, I know, but real-world conditions matter) and found the image looked washed out and uncomfortable to use. For a bedroom gaming setup with controlled lighting, it's fine. For a bright home office or a room with lots of natural light, you might find yourself squinting. The matte anti-glare coating helps with reflections, but it can't compensate for insufficient brightness.

Brightness uniformity across the panel is acceptable. The slight corner dimming I mentioned earlier is visible if you're looking for it on a plain white screen, but in normal gaming and productivity use it's not distracting. The backlight doesn't exhibit any significant clouding or dirty screen effect on my test unit. I've seen budget VA panels with terrible clouding issues, so this is worth noting as a positive. The OSD brightness control is responsive and the steps are fine enough that you can dial in a comfortable level without jumping between too-bright and too-dim.

Build quality is better than I expected for the price. The plastic feels reasonably solid, the stand doesn't wobble noticeably, and the bezels are slim on three sides with a slightly thicker bottom chin. The OSD buttons are physical buttons on the back-right of the panel, which is the standard placement for this class of monitor. They're a bit fiddly to use without looking, but you don't adjust the OSD that often once it's set up. The cable management on the stand is minimal, basically just a small clip, but it does the job.

The overall footprint is reasonable for a 27-inch curved monitor. The 1500R curve means the stand needs to sit further back on your desk than a flat panel of the same size, so factor that in if you're working with a shallow desk. The monitor arrived well packaged with foam protection, and assembly took about five minutes. No tools required. The power brick is external (a small inline adapter rather than a full brick), which keeps the cable tidy. Overall, the build is what you'd expect at this price: not premium, but not flimsy either. It feels like it'll last a few years of normal use without issues.

• 2x HDMI 1.4 (144Hz maximum at 1080p)
• 1x DisplayPort 1.2 (180Hz at 1080p)
• 3.5mm headphone output
• No USB hub
• No USB-C
• No built-in speakers

The absence of a USB hub and USB-C is expected at this price point. No built-in speakers is also standard for gaming monitors in this bracket. The 3.5mm audio output passes audio from the connected source, so you can plug headphones directly into the monitor rather than routing them to your PC. Useful if your PC is under the desk. The HDMI 1.4 specification limits bandwidth to 10.2 Gbps, which is why 180Hz isn't achievable over HDMI at 1080p on this monitor. HDMI 2.0 would have solved this, but it would also have added cost. For PC users, DisplayPort is the right cable to use anyway.

Cable routing is straightforward. The ports face downward at a slight angle on the back of the panel, which makes cable management reasonably tidy. The power connector is a standard barrel jack. One minor gripe: the OSD navigation buttons are unlabelled from the front, so you need to either memorise the layout or look at the back of the monitor each time. It's a small thing, but monitors with labelled buttons or a joystick control are genuinely easier to use. Not a dealbreaker, just a minor annoyance.

The AOC 27G2SP is a well-regarded budget option with a proper IPS panel, better out-of-box colour accuracy, and wider viewing angles. It lacks the KOORUI's contrast ratio and curve, but it handles dark-to-dark pixel transitions more cleanly. The MSI G274F is a flat IPS panel with 180Hz and a slightly higher price, offering good all-round performance without the VA smearing issue. Neither competitor has the KOORUI's 1500R curve, which is either a plus or a minus depending on your preference.

The KOORUI wins on contrast and curve. The IPS competitors win on viewing angles, ergonomics (both offer height adjustment), and cleaner motion in dark scenes. If you game in a dark room and sit directly in front of the screen, the KOORUI's VA contrast is a genuine advantage. If you share your screen, work in a bright room, or are particularly sensitive to dark smearing in games, the IPS alternatives are worth the consideration. The lack of height adjustment on the KOORUI stand is a real ergonomic disadvantage compared to the AOC 27G2SP, which does offer height adjustment at a comparable price.

The complaints cluster around a few specific areas. Dark smearing in fast-paced games comes up repeatedly, which aligns with my own testing. Several buyers mention the lack of height adjustment as a frustration, particularly taller users who find the fixed stand positions the screen too low. A handful of reviews mention backlight bleed in corners, though my test unit was clean in this regard. There are also a few mentions of the OSD being fiddly to navigate, which I'd agree with.

One pattern worth noting: buyers who came from IPS panels tend to be more critical of the VA motion characteristics, while buyers upgrading from older or lower-spec monitors tend to be more positive overall. That's a useful calibration for reading the review distribution. If you're currently on a 144Hz IPS panel and considering this as a sideways move for the curve and contrast, temper your expectations on motion clarity. If you're on a 60Hz flat panel and want a significant upgrade on a tight budget, the positive reviews are probably a fair reflection of your likely experience.

For a bedroom gaming setup where you control the lighting, sit directly in front of the screen, and play a mix of fast-paced and atmospheric games, this monitor punches above its weight. The VA contrast ratio makes horror games, space games, and cinematic titles look noticeably better than they would on a budget IPS panel. The 180Hz makes competitive shooters feel smooth. At this price point, you're not going to find a panel that does everything well, and the KOORUI makes sensible compromises.

Where the value proposition weakens is for buyers who need ergonomic flexibility (get the AOC 27G2SP instead), who game primarily in dark scenes with fast motion (the VA smearing will irritate you), or who want to use the monitor for colour-sensitive creative work (the 1080p resolution is the bigger issue there). The budget bracket is always about trade-offs, and KOORUI has made reasonable ones here. The 817 buyers who've rated this highly aren't wrong. Just make sure you're one of the people for whom the trade-offs work.

The asterisk is the 1ms claim, which is MPRT marketing rather than real GtG performance, and the VA dark smearing that comes with the panel technology. Neither is a dealbreaker for most buyers in this price bracket, but both are things you should know about before purchasing. The lack of height adjustment is a genuine ergonomic limitation that I'd flag for anyone who spends long hours at their desk.

My overall score is 7.5 out of 10. It's a good monitor for the money. Not perfect, not trying to be. If you're building a budget gaming setup and want a curved 180Hz screen with proper blacks, this is a reasonable choice. If you need IPS-quality motion clarity or ergonomic flexibility, spend a bit more or look at the flat IPS alternatives. But for what it costs, it does the job well.
