What I Actually Tested

I’ve spent three weeks with the MSI MPG 491CQP on my desk, gaming for 2-3 hours daily and working 6-8 hours. My testing setup includes an RTX 4070 Ti, Ryzen 7 7800X3D, and a desk that’s 140cm wide (barely enough, more on that later).

Games tested include:

• F1 23 and Assetto Corsa Competizione (racing sims)
• Microsoft Flight Simulator 2024 (flight sim)
• Call of Duty: Warzone and Counter-Strike 2 (competitive FPS)
• Cyberpunk 2077 and Starfield (single-player immersion)
• Baldur’s Gate 3 and Civilization VI (strategy/RPG)

Work tasks included coding in Visual Studio Code, writing in Google Docs, video editing in DaVinci Resolve, and managing multiple browser windows simultaneously. I’ve also measured power consumption with a smart plug and tested the built-in OLED Care 2.0 burn-in protection features.

Is the MSI MPG 491CQP Worth It? Price Analysis

At £797.00, the MSI MPG 491CQP represents excellent value right now. It typically sells for around £922, making this a £125 saving. That’s the lowest I’ve tracked it in the past 90 days.

Here’s the price context: when this monitor launched in late 2023, it commanded £1,200+. QD-OLED panels were rare and expensive. Fast forward to 2025, and prices have dropped significantly as manufacturing scales up. You’re getting cutting-edge display technology for £200-300 less than you’d have paid 18 months ago.

Compared to alternatives:

• Samsung Odyssey G9 OLED: £1,099 – Similar specs but Samsung’s ecosystem and slightly higher refresh (240Hz vs 144Hz)
• Alienware AW3423DWF: £799 – Smaller 34-inch 21:9 ultrawide, better for competitive gaming
• LG UltraGear 45GR95QE: £1,299 – 45-inch with 240Hz, but older WOLED tech with lower brightness

The MSI sits in a sweet spot. You’re getting 49 inches of QD-OLED goodness for less than most 34-inch ultrawides cost a year ago. If you’ve been waiting for ultrawide OLED to become affordable, this is the moment. MSI MPG 491CQP QD-OLED 49 Inch DQHD Curved Gaming Monitor-5120x1440(32:9) Quantum Dot OLED Panel,144Hz/0.03ms,99.28% DCI-P3,ΔE≤2,DisplayHDR True Black 400, KVM-DP 1.4a,HDMI 2.1,USB Type C(PD:90W)

Unboxing This Absolute Unit: Physical Reality Check

Right. Let’s talk about the elephant in the room – this monitor is massive. The box arrived on a pallet. I’m not joking. DPD delivered it separately from my usual Amazon parcels because it weighs 15kg and measures over a metre wide.

Actual dimensions: 113cm wide, 36cm tall (with stand), 30cm deep. You need a desk that’s at least 120cm wide to accommodate this beast comfortably. My 140cm desk works, but there’s precious little space for speakers or other peripherals.

The 1800R curve means the edges wrap towards you. From a 70-80cm viewing distance (where I sit), the curve feels natural after about two days of adjustment. Closer than 60cm and it’s overwhelming. Further than 90cm and you lose the immersive benefit.

Build quality impressed me. The stand offers tilt (-5° to +10°), height adjustment (0-100mm), and swivel (±15°). It’s sturdy – no wobble when typing. VESA 100mm mounting is available if you prefer an arm, though you’ll need one rated for 10kg+ loads.

One annoyance: the power brick is external and chunky. It’s the size of a small laptop charger. Not a dealbreaker, but worth knowing if cable management matters to you.

Setting Up: The Cable Situation Nobody Mentions

Here’s what caught me out initially: you need DisplayPort 1.4a or HDMI 2.1 to run this at full 5120×1440 144Hz. My older DP 1.2 cable limited me to 100Hz. I had to order a proper VESA-certified DP 1.4 cable (£15 from Amazon) to unlock the full experience.

Connectivity options:

• 1x DisplayPort 1.4a (what I use for gaming PC)
• 2x HDMI 2.1 (consoles or secondary PC)
• 1x USB-C with 90W Power Delivery (brilliant for laptops)
• USB hub: 1x Type-B upstream, 2x Type-A downstream (USB 2.0 speeds)

The USB-C port is genuinely useful. I can plug in my MacBook Pro, charge it at 90W, and use the full monitor resolution – all from one cable. For hybrid work setups, this is brilliant.

MSI’s OSD (on-screen display) navigation uses a joystick at the back right. It’s intuitive – push to select, wiggle to navigate. Far better than the fiddly buttons on cheaper monitors. The Gaming Intelligence software for Windows adds extra features like Smart Crosshair overlays and KVM switching, though I rarely use it. The hardware controls are sufficient.

How Does the MSI MPG 491CQP Perform in Racing and Flight Sims?

This is where the MSI absolutely sings. Racing sims are transformed by the 32:9 aspect ratio. In F1 23, I can see apex markers in my peripheral vision without turning the camera. Braking points, other cars alongside me, pit boards – everything’s visible naturally.

The QD-OLED panel’s 0.03ms response time means zero motion blur. When you’re hitting 250mph down the Monza straight, that clarity matters. I tested against my previous IPS panel (5ms response) and the difference is night and day. The MSI renders fast-moving trackside objects sharply whilst the IPS smeared them.

Microsoft Flight Simulator 2024 is equally brilliant. The wraparound view mimics an actual cockpit. I can monitor instruments, check wing positions, and scan for landmarks without constantly panning the camera. It’s the closest I’ve felt to proper flight sim immersion outside of VR headsets.

Brightness and HDR matter here. The MSI hits 250 nits sustained brightness and peaks at 1,000 nits for HDR highlights. In MSFS, sunlight glinting off water or clouds backlit by sunset looks properly stunning. The VESA DisplayHDR True Black 400 certification isn’t just marketing – the 1,500,000:1 contrast ratio delivers true blacks that IPS and VA panels can’t match.

One technical note: you need serious GPU power. My RTX 4070 Ti manages 80-100fps in F1 23 at high settings. MSFS drops to 45-60fps depending on location. If you’re running older than an RTX 4070 or RX 7800 XT, expect to compromise on settings. The 5120×1440 resolution has 7.4 million pixels – that’s 44% more than standard 4K.

What About Competitive FPS Gaming?

Right, honesty time. For competitive FPS games, this monitor isn’t ideal. I tested extensively in Warzone and CS2, and whilst the experience is immersive, it’s not competitive-optimal.

The FOV advantage is real. In Warzone, I spotted enemies in peripheral vision that I’d have missed on my old 27-inch 16:9. But here’s the problem: the extra width means more head movement to check corners. In fast-paced engagements, that split-second delay matters.

CS2 is worse. Competitive players need to focus on crosshair placement and tiny angles. The ultrawide format spreads information across 113cm of screen. My eyes got tired tracking from minimap to crosshair to radar. After two hours of ranked matches, I genuinely missed my compact 27-inch setup.

The 144Hz refresh is adequate but not exceptional. Competitive monitors now offer 240Hz or 360Hz. Can you feel the difference? Absolutely. Is it a dealbreaker? Depends on your rank. If you’re Platinum or below, 144Hz is fine. Diamond and above? You’ll want higher refresh rates.

Verdict for FPS players: unless you’re mainly playing single-player shooters or casual multiplayer, save your money. Get a 27-inch 1440p 240Hz monitor instead. The Alienware AW2724DM (£349) or ASUS ROG Swift PG27AQDM (£699 for OLED) make more sense for competitive gaming.

Single-Player Gaming: Pure Immersion

Where the MSI redeems itself for non-sim gamers is single-player immersion. Cyberpunk 2077 looks absolutely stunning. Night City’s neon lights pop against true blacks. The ultrawide format makes first-person exploration feel cinematic.

Starfield benefits massively from the extra horizontal space. Cockpit views show more instruments. Planetary exploration feels expansive. The 99.28% DCI-P3 colour coverage (Delta E ≤2 accuracy) means alien skies and landscapes look vivid without being oversaturated.

Baldur’s Gate 3 is brilliant on this. The isometric view shows more battlefield. I can position characters and plan tactics without constantly scrolling. Turn-based strategy games generally benefit from extra screen real estate.

But not every game works. Some titles don’t support 32:9 properly. I encountered:

• Black bars: Older games like Dark Souls III run in 16:9 with black bars either side
• Stretched UI: Some games stretch interface elements to fill the screen, making menus look weird
• Cut-off elements: A few titles position critical UI elements beyond comfortable viewing angles

The PC Gaming Wiki maintains a database of ultrawide compatibility. Check before buying if you have specific favourite games.

The QD-OLED Experience: Is It Really That Good?

Yes. Genuinely yes. Coming from an IPS panel, the difference is staggering. Let me quantify it:

Contrast ratio: My old IPS managed about 1,000:1. This QD-OLED delivers 1,500,000:1. In practical terms? True blacks. When a game shows a dark scene, pixels turn completely off. There’s no IPS glow, no backlight bleed. Just pure black.

Colour accuracy: The Delta E ≤2 rating means colours are accurate enough for professional photo editing. I’m not a photographer, but I compared images against my calibrated MacBook Pro display. The MSI matched it closely. The 99.28% DCI-P3 coverage exceeds the 98% sRGB most monitors offer.

HDR performance: This is where QD-OLED excels. The 1,000 nit peak brightness (250 nits sustained) combined with per-pixel dimming creates HDR that actually looks high dynamic range. Explosions in games have genuine punch. Sunsets show subtle gradations from bright to dark.

I tested HDR using VESA’s DisplayHDR test patterns. The True Black 400 certification is conservative – this panel exceeds it comfortably. Compare that to edge-lit LCD monitors claiming “HDR” with 400 nits and 16 dimming zones. There’s no comparison.

Motion clarity: The 0.03ms GtG response time earns a VESA ClearMR 8000 rating. In English? Fast-moving objects stay sharp. I tested with UFO Test motion blur patterns. Zero trailing, zero ghosting. The 144Hz refresh combined with near-instant pixel response creates buttery smooth motion.

One quirk: text clarity for productivity. QD-OLED uses a triangular subpixel layout (not RGB stripe). Windows ClearType assumes RGB stripe, so text can look slightly fuzzy initially. I spent 10 minutes adjusting ClearType settings and text sharpness in Windows. After tweaking, text looked fine for daily work. But if you’re a graphic designer scrutinising typography, be aware of this limitation.

Burn-In: Should You Actually Worry?

Right, the elephant in the room. OLED burn-in. Everyone asks about it. Here’s my honest take after three weeks and research into long-term QD-OLED reliability.

Modern QD-OLED panels are far more resistant than older OLED TVs from 2016-2018. Samsung’s Gen 3 QD-OLED (which MSI uses) includes:

• Graphene heatsink: Fanless cooling that keeps pixels cooler, extending lifespan
• Improved materials: Blue OLED subpixels (the ones that degrade fastest) now last 2-3x longer
• Firmware protection: Pixel shift, logo dimming, screen savers

MSI adds OLED Care 2.0 software with:

• Pixel refresh cycles (runs automatically after 4 hours off)
• Taskbar hiding (dims static Windows elements)
• Screen saver activation after 5 minutes idle
• Pixel shift (moves image 1 pixel every few minutes)

My usage pattern: 2-3 hours gaming (varied content), 6-8 hours work (static browser, code editor). After three weeks, zero signs of image retention. I ran a grey uniformity test – perfectly even.

Will burn-in happen eventually? Probably, if you display static content 8+ hours daily for years. But RTINGS’ long-term OLED burn-in testing shows modern panels lasting 5,000-10,000 hours before visible degradation with worst-case static content.

Would I buy this with my own money? Yes, with caveats. If you vary content (gaming, videos, work), you’ll be fine. If you plan to leave static dashboards or trading charts on-screen 12 hours daily, maybe buy an IPS monitor instead.

MSI includes a 3-year warranty. Check if it covers burn-in (policies vary by retailer). Amazon UK’s return policy gives you 30 days to test risk-free.

How Does the MSI MPG 491CQP Handle Productivity Work?

I’ve worked 8-hour days on this monitor for three weeks. Here’s the reality of ultrawide productivity.

Window management: Brilliant. I run three windows side-by-side comfortably. Typical setup: code editor (centre), documentation (left), terminal (right). The 5120 pixel width gives each window about 1707 pixels – equivalent to three 1080p monitors.

Windows 11’s Snap Layouts work perfectly. You can snap windows to thirds, halves, or quarters. I also tested PowerToys FancyZones for custom layouts. Within a day, I’d created zones for my workflow and productivity genuinely improved.

Video editing: DaVinci Resolve shines here. Timeline across the bottom, preview in centre, effects/media bins on sides. I didn’t need my secondary monitor. Everything fit on the ultrawide with room to spare.

Text clarity: After ClearType adjustment, fine for 8-hour days. I’m not a designer, so the subpixel layout quirk doesn’t affect me. If you work with typography or detailed graphics, test it first. Some users are sensitive to the triangular subpixel arrangement.

Neck strain: Real talk – the first week, my neck ached. The 113cm width means more head turning. I adjusted my viewing distance from 70cm to 80cm and lowered the monitor slightly. That fixed it. Now it’s comfortable.

Optimal viewing distance: 75-85cm. Closer and you’re turning your head constantly. Further and you lose the immersive benefit.

Power consumption: I measured with a smart plug. Typical usage (250 nits brightness, SDR content): 65-75W. HDR gaming peaks at 110-130W. Standby: 0.5W. Over 8 hours of work, that’s about 0.5-0.6 kWh daily. At UK electricity prices (£0.24/kWh average), that’s 12-14p per day or £3.60-4.20 monthly.

Compare that to running three separate monitors (3 x 30W = 90W), and the ultrawide is actually more efficient.

What Do 312 UK Buyers Actually Say?

With 312 verified UK buyers rating this 4.3/5 stars, the MSI MPG 491CQP has solid social proof. I’ve read through dozens of reviews to identify common themes.

What buyers love:

• Picture quality is the most praised aspect – “stunning colours”, “true blacks”, “best panel I’ve owned”
• Immersion in racing sims specifically mentioned in 40+ reviews
• Build quality and stand stability consistently praised
• USB-C with 90W Power Delivery highlighted by MacBook/laptop users

Common complaints:

• Size – about 15% of reviews mention it being larger than expected or desk space issues
• Text clarity – 10% of buyers note the subpixel layout affecting text sharpness
• Gaming compatibility – some mention specific games not supporting 32:9 properly
• Price – several reviews from early adopters paid £1,100+ and wish they’d waited

The 4.3★ rating is fair. This isn’t a perfect monitor for everyone. It’s a specialist tool that excels in specific use cases (sims, productivity, immersive gaming) whilst being overkill or suboptimal for others (competitive FPS, small desks, tight budgets).

Interestingly, the negative reviews (1-2 stars) mostly cite delivery damage or DOA units, not inherent product flaws. MSI’s quality control seems solid – defects are rare.

How Does the MSI MPG 491CQP Compare to Competitors?

The 49-inch ultrawide market has three main contenders. Here’s how they stack up:

MSI MPG 491CQP vs Samsung Odyssey G9 OLED: Both use the same QD-OLED panel generation. The Samsung costs £302 more but offers 240Hz refresh (vs 144Hz) and Samsung’s ecosystem features. If you play competitive games and can afford it, the Samsung makes sense. For everyone else? Save £300 and get the MSI. The 144Hz vs 240Hz difference matters far less in racing sims and single-player games.

MSI MPG 491CQP vs LG UltraGear 45GR95QE: The LG uses older WOLED technology (not QD-OLED), costs £502 more, and offers 240Hz. The WOLED panel has lower peak brightness (800 vs 1,000 nits) and less vibrant colours. Unless you specifically want the 45-inch size (slightly less wide than 49″), the MSI offers better value and picture quality.

My recommendation: the MSI MPG 491CQP is the best value in this category. You’re getting 90% of the Samsung’s performance for 73% of the price. MSI MPG 491CQP QD-OLED 49 Inch DQHD Curved Gaming Monitor-5120x1440(32:9) Quantum Dot OLED Panel,144Hz/0.03ms,99.28% DCI-P3,ΔE≤2,DisplayHDR True Black 400, KVM-DP 1.4a,HDMI 2.1,USB Type C(PD:90W)

Should You Buy the MSI MPG 491CQP?

Buy if you:

• Play racing sims or flight simulators regularly – this is transformative
• Want immersive single-player gaming (RPGs, open-world games)
• Need productivity multitasking with multiple windows
• Have desk space (120cm+ width minimum)
• Own a powerful GPU (RTX 4070 Ti / RX 7800 XT or better)
• Value picture quality over competitive refresh rates
• Budget allows £700-900

Skip if you:

• Mainly play competitive FPS games → Get the ASUS ROG Swift PG27AQDM (27″ 1440p 240Hz OLED, £699) instead
• Have limited desk space → Consider the Alienware AW3423DWF (34″ 21:9 ultrawide, £799)
• Budget under £700 → Wait for sales or get the Gigabyte M34WQ (34″ IPS ultrawide, £399)
• Need perfect text clarity for design work → IPS panels have better subpixel layouts
• Worry about OLED burn-in → Stick with IPS or VA technology

The MSI MPG 491CQP isn’t a monitor for everyone. It’s a specialist tool that excels in specific scenarios. If those scenarios match your needs, this is brilliant value at £797. If they don’t, you’ll be paying for features you won’t use.

Final Verdict: Ultrawide Perfection?

After three weeks with the MSI MPG 491CQP, I can confidently say it’s the best value 49-inch ultrawide OLED you can buy in 2025. The QD-OLED panel delivers stunning picture quality, the 144Hz refresh and 0.03ms response create smooth motion, and the build quality justifies the £797 price tag.

It’s transformed my racing sim experience. F1 23 and Assetto Corsa feel like different games with the peripheral vision advantage. Productivity has genuinely improved – three windows side-by-side beats my old dual-monitor setup. And single-player games like Cyberpunk 2077 look absolutely stunning with true blacks and vibrant colours.

But it’s not perfect. Competitive FPS players should look elsewhere – the ultrawide format creates disadvantages in fast-paced games. The physical size demands serious desk space. And the text clarity quirk means graphic designers might prefer IPS panels.

At £797 (down from the typical £922), this represents excellent value. You’re getting cutting-edge QD-OLED technology for less than most 34-inch ultrawides cost. The Samsung Odyssey G9 OLED offers marginally better specs for £302 more, but the MSI delivers 90% of the experience for 73% of the price.

Would I recommend this? Absolutely – to the right buyer. If you’re a sim racing enthusiast, productivity multitasker, or immersive single-player gamer with desk space and a powerful GPU, this is brilliant. If you’re a competitive FPS player or have a tight budget, save your money.

The MSI MPG 491CQP isn’t ultrawide perfection for everyone. But for its target audience, it’s pretty damn close.
