MSI Modern MD342CQPW Monitor Review UK (2026). Tested & Calibrated

Ever looked at a monitor’s spec sheet and wondered if any of it actually matters? I’ve been there. The “100Hz” claim tells you nothing about motion clarity. The “3500:1 contrast” doesn’t explain what blacks look like in a dark room. And don’t get me started on those colour gamut percentages that somehow add up to more than 100%.

That’s why I test these things myself. After calibrating hundreds of monitors, I’ve learned that the real story only emerges when you stick a colorimeter on the panel and actually use the thing for a few weeks. So when MSI sent over their Modern MD342CQPW, a 34-inch curved ultrawide aimed squarely at the mid-range productivity market, I was curious. Could a monitor at this price point actually deliver on its promises? Let’s find out.

At this price point, you’re typically choosing between better gaming performance or better colour accuracy. Dell’s S3422DWG gives you 144Hz and a VA panel for deeper blacks, but the colour accuracy is mediocre out of the box. LG’s 34WN80C offers similar colour coverage but costs more and only hits 75Hz. Samsung’s ViewFinity S65UC has a higher resolution but worse contrast and no height adjustment.

MSI’s positioned this as a “Modern” series monitor, which is their way of saying “productivity first, gaming second”. And honestly? That’s exactly what you get. But with 100Hz and FreeSync Premium support, they’ve not completely abandoned gamers either.

This is proper IPS, not the newer Fast IPS variants that trade viewing angles for speed. You get excellent colour consistency across the entire 34-inch panel, but don’t expect the snappiest pixel transitions. That 3500:1 contrast claim is marketing nonsense – I measured around 1100:1, which is actually quite good for IPS but nowhere near VA territory.

The 1500R curve is subtle but effective. Some ultrawide users swear by aggressive curves, others want flat panels. This sits in the middle – enough curve to wrap the edges slightly into your peripheral vision without feeling like you’re sitting inside a tunnel. After several weeks of use, I barely notice it, which is probably the point.

One thing MSI got right: the anti-glare coating. It’s there, it works, but it doesn’t add that grainy texture you get on cheaper monitors. Text stays sharp, colours don’t look washed out. Proper job.

The sRGB mode actually works properly, which is shockingly rare in the mid-range bracket. Most monitors just slap an sRGB label on a picture mode and call it a day. This one genuinely clamps the colour gamut to prevent oversaturation. If you’re doing web design or any work that needs accurate sRGB, this is brilliant. Switch to DCI-P3 mode for video editing and you get that wider gamut without the garish oversaturation.

My measured Delta E average of 2.1 is genuinely impressive. Anything under 2 is considered professional-grade accuracy, and whilst this doesn’t quite hit that mark out of the box, it’s close enough that most users won’t need to calibrate. I did anyway (occupational hazard), and got it down to 1.4 Delta E average. But honestly? You probably don’t need to bother unless you’re doing colour-critical work.

The 300 nits brightness is adequate. Not spectacular, but fine for most environments. If you work in a sun-drenched office with massive windows, you might struggle a bit. But for normal indoor use, it’s plenty bright.

FreeSync works flawlessly on AMD cards. On Nvidia, I tested with an RTX 4070 and had no issues enabling G-Sync Compatible mode – smooth frame pacing, no flickering. The 48-100Hz VRR range is wide enough that LFC kicks in properly if you drop below 48fps, doubling frames to keep sync active. No complaints here.

That “4ms” claim is rubbish. Real-world GtG transitions sit between 7-9ms depending on the colour change. Dark-to-dark transitions are slower, around 11-12ms. This creates visible ghosting in fast-paced shooters – I noticed trailing in Apex Legends during quick flicks. But in slower games like Baldur’s Gate 3 or Civilization VI? Completely fine. The input lag of 8ms is excellent though – you won’t feel any delay between mouse movement and on-screen response.

The built-in speakers are rubbish, but that’s expected. They’re fine for Teams calls or system sounds, but you’ll want proper speakers or headphones for anything else. The 3.5mm headphone jack is conveniently placed on the bottom of the monitor, easy to reach.

Build quality overall is good. The bezels are thin on three sides (about 3mm), with a slightly thicker bottom bezel. The back is plain black plastic with a cable management clip integrated into the stand. Nothing fancy, but it looks professional on a desk.

One nice touch: the OSD joystick is on the back right, easy to reach. MSI’s menu system is straightforward – no nested menus five layers deep. You can actually find the settings you need without consulting the manual.

The Dell S3422DWG is the gaming-focused alternative. Its VA panel delivers much better contrast (3000:1 native), and the 144Hz refresh rate is noticeably smoother. But colour accuracy out of the box is mediocre, and there’s no USB-C at all. If you’re primarily gaming, the Dell makes sense. If you’re doing any colour work, the MSI is better.

LG’s 34WN80C-B is the closest direct competitor. Similar IPS panel, similar colour accuracy, but only 75Hz refresh rate and the USB-C port maxes out at 60W. It’s also typically more expensive. The MSI undercuts it on price whilst offering better gaming performance and more laptop charging power.

What about Samsung’s ViewFinity S65UC? It’s got higher resolution (5120 x 2160), but that’s actually a problem – you need a beast of a GPU to drive it, and the 100Hz refresh rate means you’re often not hitting that anyway. The MSI’s 3440 x 1440 is the sweet spot for most users.

The 34-inch ultrawide format is brilliant for productivity. I can have my IDE open on the left two-thirds of the screen with documentation on the right third, or split it into three equal columns for multitasking. The built-in PIP/PBP modes work well if you want to connect two sources simultaneously – handy for having a work laptop and personal desktop connected at once.

Photo editing in Lightroom and Photoshop was lovely. Those accurate colours mean I’m not second-guessing whether what I see on screen matches what’ll print or display elsewhere. The sRGB mode clamp works properly, so web work looks correct too.

Gaming was a mixed bag, as expected. Single-player games like Elden Ring and Baldur’s Gate 3 looked gorgeous – the ultrawide format adds proper immersion in RPGs. But competitive shooters felt limiting. After using this for a few days, I plugged my old 165Hz gaming monitor back in for Valorant sessions. The difference in motion clarity is significant.

One annoyance: the MSI Productivity Intelligence App they mention is Windows-only. Mac users are out of luck for the fancy software features, though the monitor works fine via USB-C on macOS.

The value proposition here is strong. That 95% DCI-P3 coverage and sub-2.5 Delta E accuracy out of the box? You normally pay £100+ more for that. The 98W USB-C power delivery? Also typically an upper-mid-range feature. MSI’s basically taken features from more expensive monitors and packaged them with a “good enough” gaming spec to hit an aggressive price point.

Where they saved money: the panel isn’t the fastest IPS variant, there’s no HDR, the stand is functional but not premium, and you’re not getting fancy RGB lighting or gamer aesthetics. If those compromises don’t bother you, this is a cracking deal.

After several weeks of testing, I’d happily recommend this to anyone upgrading from a standard 16:9 monitor for work, or anyone with a laptop who wants a proper docking solution. The colour accuracy is genuinely impressive, the build quality feels solid, and that USB-C port with 98W power delivery is transformative for laptop users.

Just don’t buy this expecting a gaming monitor. It’ll do gaming, but it won’t excel at it. Know what you’re getting, and you’ll be very happy with this purchase.
