💷 Price: £265
✅ Best for: Immersive single-player gaming, productivity multitasking, budget-conscious gamers wanting ultrawide without £500+ spend
❌ Skip if: You’re a hardcore competitive FPS player, need perfect colour accuracy for editing, or can’t tolerate any ghosting
I’ll be honest—when I saw the AOC CU34G2XP listed at £265, I thought something had to be wrong. A 34-inch ultrawide with 180Hz refresh rate and 1440p resolution for less than most 27-inch monitors? Seemed proper dodgy.
But I’ve spent three weeks gaming, working, and genuinely living with this monitor as my daily driver. And here’s the thing: it’s not perfect, but it’s brilliant value if you know what you’re getting into.
You’re going to learn exactly where this monitor shines (immersion is genuinely impressive), where it falls flat (VA panel ghosting is real), and whether you should grab one before the price inevitably creeps up. No marketing rubbish—just what I actually found after proper testing.
What I Tested
Full transparency on my testing setup so you know this isn’t theoretical nonsense:
- GPU: RTX 4070 and RX 7800 XT (tested both AMD and Nvidia adaptive sync)
- Games: Cyberpunk 2077, Baldur’s Gate 3, Warzone, CS2, Forza Horizon 5, Resident Evil 4 Remake
- Work tasks: Video editing in DaVinci Resolve, photo editing in Lightroom, spreadsheet work, writing
- Testing period: Three weeks, minimum 6 hours daily use
- Calibration: Tested out-of-box and after calibration with Spyder X Pro
I’ve also compared it directly against the Samsung Odyssey G5 34-inch (£320) and my previous daily driver, an LG 34GP63A (£380). Context matters.
Price Analysis: Is £265 Fair Value?
Let’s talk money because this is where things get interesting. The AOC CU34G2XP currently sits at £265 on Amazon UK. According to the 90-day pricing data, it typically sells for around £253, so you’re paying roughly £12 above the recent average. Not a massive deal, but not a steal either.
Here’s the crucial bit: comparable 34-inch ultrawides with similar specs are sitting between £320-£450 right now. The Samsung G5 34-inch? £320. The LG 34GP63A? £380. The Dell S3422DWG? £399. You’re saving £55-£135 by going with the AOC.
What are you sacrificing for that saving? Honestly, not as much as you’d expect. The main compromises are brand recognition (AOC isn’t as sexy as Dell or LG) and some firmware polish. The actual panel performance? Shockingly close to monitors costing £100 more.
For context, I paid £380 for my LG ultrawide 18 months ago. If the AOC CU34G2XP had existed then at this price, I’d have saved £115 and gotten a nearly identical experience. That stings a bit, but it’s brilliant news for you. AOC Gaming CU34G2XP - 34 Inch WQHD Curved Monitor, VA, 180Hz, 1ms GtG, HDR400, Height Adjust, Game Mode, Speakers (3440 x 1440, 400 cd/m HDMI 2.0 / DP 1.4)
AOC CU34G2XP Technical Specifications Explained
Right, let’s break down what you’re actually getting, because specs on paper mean nothing without context.
Display Panel: 34-Inch VA with 1000R Curve
The 3440×1440 resolution gives you 5 million pixels to play with. That’s 33% more screen real estate than standard 1440p. In practical terms? You can have Discord, Spotify, and your game visible simultaneously without alt-tabbing. For work, it’s two full A4 pages side-by-side with room to spare.
The 1000R curve means if you formed this screen into a complete circle, it’d have a 1-metre radius. That’s quite aggressive—more curved than the gentler 1500R or 1800R curves on some competitors. I was sceptical, but after two days, I stopped noticing it. Now when I use a flat monitor, it feels weird. The curve genuinely helps with immersion in games like Cyberpunk where peripheral vision matters.
VA panel technology is the key trade-off here. You get spectacular contrast (3000:1 native, which makes blacks actually look black), but response times aren’t as quick as IPS. More on that in the performance section, because it matters for certain game types.
Refresh Rate: 180Hz (Overclocked from 165Hz)
Out of the box, you get 165Hz. Enable the overclock mode in the OSD menu, and you hit 180Hz. The difference between 165Hz and 180Hz? Imperceptible to human eyes, honestly. The jump from 60Hz to 165Hz? That’s transformative. Smooth as butter.
Important caveat: you’ll need DisplayPort 1.4 to hit 180Hz at full resolution. HDMI 2.0 maxes out at 100Hz at 3440×1440. The monitor ships with a DisplayPort cable, so you’re sorted, but console gamers take note.
Response Time: 1ms MPRT (Not GtG)
Here’s where marketing gets slippery. AOC claims 1ms response time, but that’s MPRT (Moving Picture Response Time), not the more common GtG (Grey-to-Grey) measurement. According to AOC’s official specs, the actual GtG response is closer to 4ms.
What does that mean for you? In fast-paced FPS games, you might notice slight motion blur or ghosting in high-contrast scenes. I certainly did in Warzone. But in single-player games or slower competitive titles? Not an issue. We’ll dig deeper into this shortly.
HDR400 Certification
The monitor supports HDR400, which is the entry-level VESA DisplayHDR certification. Peak brightness hits 400 nits. That’s enough to make highlights pop in supported games, but it’s not proper HDR like you’d get from a £1000+ monitor with local dimming.
My honest take? I leave HDR off 90% of the time. It washes out colours in Windows, and most games don’t implement it well at this brightness level. When it works (Resident Evil 4 Remake looked gorgeous), it’s a nice bonus. But don’t buy this monitor for HDR. Buy it despite HDR400 being a bit rubbish.
Build Quality and What’s in the Box
The stand is surprisingly decent. You get height adjustment (110mm range), tilt (-5° to +21°), but no swivel. At 8.02kg, it’s hefty enough to feel solid without being a nightmare to move. The base is stable—no wobble when typing.
In the box: monitor, stand, DisplayPort 1.4 cable, HDMI 2.0 cable, power cable, quick start guide. No USB cable for the hub, which is annoying because the monitor has a 4-port USB 3.2 hub built in. You’ll need to buy a USB-B to USB-A cable separately (about £6) to use that feature.
AOC CU34G2XP Performance: Real-World Gaming Tests
This is what you actually care about. Does it game well?
GPU Requirements: What You Need
Let’s be blunt: 3440×1440 at high refresh rates is demanding. You’re pushing 44% more pixels than standard 1440p. Here’s what I found with different GPUs:
- RTX 4070 / RX 7800 XT: Sweet spot. High/Ultra settings in most games, 100-140fps average. Occasional dips to 80fps in Cyberpunk’s most demanding areas.
- RTX 4060 Ti / RX 7700 XT: Medium/High settings, 80-120fps. Perfectly playable but you’ll tweak settings.
- RTX 3060 / RX 6700 XT: Medium settings, 60-90fps. Still good, but you’re not using that 180Hz refresh properly.
Bottom line: I’d recommend at least an RTX 4060 Ti or RX 7700 XT tier GPU. Anything less and you’re wasting the high refresh rate capabilities.
FPS Games: The Ghosting Reality
Right, let’s address the elephant in the room. I tested Warzone and CS2 extensively because these games expose every panel weakness.
In Warzone, I noticed ghosting when quickly panning across high-contrast scenes—think looking from a bright window into a dark room. It’s not game-breaking, but it’s there. The overdrive setting helps (set it to Strong, not Extreme which causes inverse ghosting), but doesn’t eliminate it completely.
CS2 was better because the maps have less extreme contrast. At 165Hz, the game felt responsive and smooth. Could I perform better on a 240Hz IPS panel? Probably. But I’m a Gold Nova scrub, so the monitor isn’t my limiting factor. If you’re Faceit Level 10, get an IPS panel. If you’re a normal human, this is fine.
The adaptive sync works brilliantly with both AMD FreeSync and Nvidia G-Sync Compatible. No tearing, no stuttering. Just smooth gameplay within the VRR range (48-180Hz).
Single-Player Games: Where This Monitor Shines
This is where the AOC CU34G2XP properly delivers. Cyberpunk 2077 in ultrawide is transformative. The extra peripheral vision makes Night City feel more immersive than any 16:9 monitor I’ve used. Driving through the city, you can see side streets in your peripheral vision. Combat feels more spatial.
Baldur’s Gate 3 benefits massively from the extra horizontal space. You see more of the battlefield, which is a genuine tactical advantage. The VA panel’s deep blacks make the game’s darker dungeons look atmospheric rather than washed out.
Forza Horizon 5 at 120fps on this ultrawide? Absolutely brilliant. The curve enhances the sense of speed, and the colours are vibrant enough to make Mexico’s landscapes pop. This is the use case where you’ll forget this monitor cost £265.
HDR Gaming: Skip It
I tried HDR in Resident Evil 4 Remake, Cyberpunk, and Forza. Results were mixed at best. The 400-nit peak brightness isn’t enough for proper HDR impact, and the lack of local dimming means you don’t get the contrast HDR is supposed to provide.
Resident Evil 4 looked decent, but I preferred SDR with boosted in-game brightness. Cyberpunk’s HDR implementation is notoriously dodgy anyway. Forza was the best HDR experience, but again, SDR looked nearly as good.
My advice? Ignore the HDR400 badge. It’s a marketing checkbox, not a real feature. AOC Gaming CU34G2XP - 34 Inch WQHD Curved Monitor, VA, 180Hz, 1ms GtG, HDR400, Height Adjust, Game Mode, Speakers (3440 x 1440, 400 cd/m HDMI 2.0 / DP 1.4)
Image Quality and Colour Accuracy
VA Panel Advantages: Contrast Is King
The 3000:1 native contrast ratio is the star of the show. Blacks look properly black, not the greyish-black you get from IPS panels. When I loaded up a full-screen black image, my room got noticeably darker. That’s proper contrast.
For gaming and movies, this makes a huge difference. Dark scenes in games like Resident Evil 4 have depth and atmosphere. You can see details in shadows without the image looking washed out. Coming from an IPS panel, this was the biggest positive surprise.
Colour Accuracy: Good Enough, Not Perfect
Out of the box, colours are punchy but slightly oversaturated. My Spyder X Pro measured 98% sRGB coverage and 82% DCI-P3. That’s respectable for a gaming monitor at this price.
After calibration, I got Delta E values around 2.5, which is good enough for casual photo editing but not professional colour work. If you’re a photographer or video editor who needs perfect colour accuracy, spend £500+ on a proper editing monitor. For everyone else? These colours look great.
Skin tones in games looked natural. Grass looked green, not neon lime. The sky in Forza looked properly blue. That’s the bar for gaming monitors, and this clears it comfortably.
Viewing Angles: The VA Panel Weakness
Here’s the trade-off for that gorgeous contrast: viewing angles are mediocre. Sit dead centre and it looks brilliant. Move 30 degrees off-axis and you’ll notice colour shift and contrast degradation.
Does this matter? Not for solo gaming where you’re always centred. But if you’re showing something to a mate standing beside you, they’ll see a worse image than you. The 1000R curve actually helps here by keeping the edges equidistant from your eyes, but the VA panel limitations are still there.
Backlight Bleed and Uniformity
I tested with a full black screen in a dark room. There’s minimal backlight bleed from the corners—barely noticeable unless you’re specifically looking for it. Panel uniformity is good, with no obvious bright or dark patches.
I’ve seen worse uniformity on £400 monitors, so AOC’s quality control seems solid. Obviously, panel lottery is a thing, but my unit was fine.
Brightness: More Than Enough for UK Rooms
Peak SDR brightness hits 350 nits, which is plenty for typical UK rooms. I run it at 60% brightness most of the time. Even with my desk facing a window, I’ve never wished it was brighter.
The anti-glare coating is effective without being overly grainy. You’ll see some reflections if you have a bright light directly behind you, but it’s manageable.
Daily Use and Productivity
Gaming is one thing, but I also work from home, so this monitor needed to handle 8-hour workdays.
Productivity: Ultrawide Real Estate Pays Off
For productivity, this monitor is genuinely transformative. I can have a full-width browser window with documentation on one side and my code editor on the other. No second monitor needed.
Video editing in DaVinci Resolve benefits hugely. Timeline on the bottom, preview on top-left, media pool on top-right, all visible simultaneously. The 3440-pixel width means I can see more of my timeline without zooming out.
Spreadsheets? You can see columns A through Z without scrolling. Writing? Two full pages side-by-side for reference. It’s the kind of upgrade that makes you wonder how you tolerated 16:9 for so long.
OSD Menu: Actually Well Designed
The on-screen display uses a joystick on the back-right of the monitor. It’s responsive and the menu layout is logical. You can quickly switch between preset modes (FPS, RTS, Racing, etc.) or dive into detailed settings.
I created a custom profile with my preferred colour temperature, contrast, and overdrive settings. Switching between this and the FPS preset takes three seconds. No complaints here—it’s better than the fiddly button arrays on some competitors.
Stand and Ergonomics
The stand offers 110mm of height adjustment, which was enough to get the monitor at proper eye level on my desk. Tilt range is -5° to +21°, which covers most use cases.
The lack of swivel is annoying if you occasionally need to show your screen to someone beside you, but it’s a common omission at this price point. The monitor is VESA 100×100 compatible if you want to use a monitor arm instead.
Cable management is basic—there’s a clip on the stand to route cables through, but it’s not elegant. Functional, not pretty.
Ports and Connectivity
Round the back you get:
- 2x HDMI 2.0 (100Hz max at 3440×1440)
- 2x DisplayPort 1.4 (180Hz max)
- 3.5mm audio jack
- 4x USB 3.2 ports (requires USB-B connection to PC, cable not included)
The dual DisplayPort inputs are brilliant if you have multiple PCs or a work laptop and gaming PC. The USB hub is useful for connecting peripherals, though you’ll need to buy that USB-B cable.
Eye Strain and Comfort
After three weeks of 6+ hour daily sessions, I haven’t experienced unusual eye strain. The flicker-free backlight and low blue light mode (which I don’t use because it makes everything orange) are there if you need them.
The curve does reduce eye movement compared to a flat ultrawide, which might contribute to comfort. Or it might be placebo. Either way, I’m comfortable using this all day.
The Annoying Bits (Every Monitor Has Them)
Right, let’s talk about what’s genuinely annoying, because no monitor at £265 is perfect.
Ghosting in Fast Scenes
We’ve touched on this, but it’s worth emphasising: if you’re sensitive to ghosting, the VA panel will bother you. In high-contrast, fast-motion scenarios (think panning quickly in Warzone), you’ll see trailing. The overdrive setting helps but doesn’t eliminate it.
For competitive FPS players, this is a deal-breaker. For everyone else, it’s a minor annoyance you’ll adapt to. I stopped noticing after a week unless I specifically looked for it.
Black Smearing: The VA Panel Tax
When dark objects move across dark backgrounds, you’ll notice black smearing—a sort of trailing effect. It’s inherent to VA panel technology. Load up a game with a dark UI moving across a dark background, and you’ll see it.
Is it terrible? No. Is it noticeable? Yes, if you’re looking. Would I trade the gorgeous contrast for slightly better motion handling? Honestly, no. But your mileage may vary.
Built-In Speakers: Genuinely Rubbish
The 2x 5W speakers are hilariously bad. Tinny, no bass, distortion at higher volumes. They’re fine for system sounds or emergency Zoom calls when your headset dies, but that’s it.
Use headphones or external speakers. Consider the built-in speakers a bonus for convenience, not actual audio.
Firmware Quirks
Occasionally, my custom colour profile resets after the monitor goes to sleep. It’s rare (happened three times in three weeks), but annoying when it does. A quick switch to another preset and back fixes it.
The auto-input detection is also a bit slow. Switching between HDMI and DisplayPort takes 3-4 seconds, which feels sluggish compared to some monitors.
What I Wish Was Better
If I could change three things:
- Include the USB-B cable. You’ve built a USB hub into the monitor—include the bloody cable to use it.
- Add swivel to the stand. Even 20 degrees would be useful.
- Improve the HDR implementation. Either do it properly or don’t bother. HDR400 is pointless.
But these are minor gripes in the context of a £265 ultrawide that performs this well.
AOC CU34G2XP vs Competitors: Worth the Upgrade?
Let’s compare the AOC CU34G2XP to its main rivals in the £250-£400 bracket.
| Monitor | Price | Panel | Refresh Rate | Key Advantage | Key Disadvantage |
|---|---|---|---|---|---|
| AOC CU34G2XP | £265 | VA | 180Hz | Best value, great contrast | VA ghosting |
| Samsung Odyssey G5 34″ | £320 | VA | 165Hz | Brand recognition, slightly better build | £55 more for similar performance |
| LG 34GP63A | £380 | IPS | 160Hz | Better motion clarity, IPS colours | Worse contrast, £115 more |
| Dell S3422DWG | £399 | VA | 144Hz | Dell warranty, better OSD | Lower refresh rate, £134 more |
vs Samsung Odyssey G5 34-Inch
The Samsung is £55 more and uses a similar VA panel. You get marginally better build quality and Samsung’s brand reputation. Performance? Nearly identical. The AOC actually has a higher refresh rate (180Hz vs 165Hz).
Unless you specifically want a Samsung badge, save the £55. Put it toward a better GPU instead.
vs LG 34GP63A
The LG uses an IPS panel, which means better motion clarity and no black smearing. Viewing angles are also superior. But you lose the gorgeous contrast—blacks look grey in comparison.
If you play competitive FPS games primarily, the £115 premium for the LG might be worth it. For single-player and productivity? The AOC’s contrast wins. I’ve used both, and I’d take the AOC for everything except competitive gaming.
vs Dell S3422DWG
The Dell offers Dell’s excellent warranty and a slightly better OSD, but it’s £134 more expensive and only hits 144Hz. The panel performance is similar to the AOC—both are VA with similar ghosting characteristics.
You’re paying for Dell’s brand and support. If that’s worth £134 to you, go for it. For most people, it’s not.

Social Proof: What Buyers Say (When Reviews Exist)
Here’s the awkward bit: this monitor has zero reviews on Amazon UK at the time of writing. It’s a newer model, so the review count hasn’t built up yet.
What I can tell you is that the previous model, the CU34G2X (without the P), has generally positive feedback across various retailers, with buyers praising the value and immersion but noting the typical VA panel motion handling.
The CU34G2XP improves on that model with a higher refresh rate (180Hz vs 144Hz) and better stand adjustability. So the feedback on the older model is relevant, with the new version addressing some of the previous complaints.
I’d expect reviews to skew positive once they accumulate, with the usual caveats about ghosting for competitive gamers. The lack of reviews right now means you’re getting in early—which also means you’re taking a bit more risk. My three weeks of testing should help mitigate that. AOC Gaming CU34G2XP - 34 Inch WQHD Curved Monitor, VA, 180Hz, 1ms GtG, HDR400, Height Adjust, Game Mode, Speakers (3440 x 1440, 400 cd/m HDMI 2.0 / DP 1.4)
Should You Buy the AOC CU34G2XP?
After three weeks of proper testing, here’s my honest recommendation.
✅ Buy This Monitor If:
- You prioritise immersion over competitive edge. Single-player games look spectacular on this ultrawide.
- Budget is £250-£300. You won’t find better ultrawide value at this price point.
- You want a productivity boost. The ultrawide real estate genuinely improves workflow.
- You value contrast. VA panel blacks are gorgeous for movies and atmospheric games.
- You have a mid-to-high-tier GPU. RTX 4060 Ti / RX 7700 XT minimum to drive this properly.
❌ Skip This Monitor If:
- You’re a competitive FPS player. The ghosting will annoy you. Get the LG 34GP63A (£380) instead for IPS motion clarity.
- You need perfect colour accuracy. This isn’t a professional editing monitor. Look at BenQ’s SW series if colour is critical.
- You’re sensitive to motion blur. VA panels aren’t for you. Spend more on IPS or TN.
- You want proper HDR. HDR400 is rubbish. Save for an HDR1000 monitor if HDR matters.
- Your GPU is below RTX 4060 / RX 7700 XT. You won’t utilise the high refresh rate anyway.
Alternative Recommendations
If the AOC doesn’t quite fit your needs:
- Competitive gamers: Get the LG 34GP63A (£380) for IPS motion handling.
- Tighter budget: Consider a 27-inch 1440p 165Hz monitor like the Gigabyte M27Q (£240) instead of ultrawide.
- Console gamers: This isn’t ideal for PS5/Xbox. Get a 4K 120Hz TV instead.
- Professional work: Look at the BenQ PD3420Q (£700) for proper colour accuracy and USB-C.
Final Verdict
The AOC CU34G2XP delivers ultrawide gaming and productivity at a price that seemed impossible two years ago. For £265, you get a 34-inch 1440p curved panel with 180Hz refresh rate, excellent contrast, and solid build quality.
Yes, the VA panel has motion handling quirks. Yes, the HDR is pointless. Yes, the speakers are rubbish. But in the context of a £265 ultrawide? These are acceptable compromises.
I’ve genuinely enjoyed using this monitor for three weeks. Cyberpunk was more immersive, productivity was smoother, and I didn’t feel like I’d sacrificed image quality to save money. That’s the sweet spot.
If you’re a competitive FPS player, spend more on IPS. For everyone else—single-player gamers, productivity users, budget-conscious buyers wanting ultrawide immersion—this is the monitor to get right now. AOC Gaming CU34G2XP - 34 Inch WQHD Curved Monitor, VA, 180Hz, 1ms GtG, HDR400, Height Adjust, Game Mode, Speakers (3440 x 1440, 400 cd/m HDMI 2.0 / DP 1.4)
Rating: 4.2/5
Deductions for VA ghosting (-0.5), mediocre HDR (-0.2), and missing USB-B cable (-0.1). But at £265, it’s brilliant value that punches well above its price.
