Lenovo Legion Pro 34WD-10 OLED review: A gorgeous ultra-wide that's perfect for immersive gaming
With its 240Hz refresh rate and 0.03ms GTG (I'll explain this more later), it's perfectly capable of competitive FPS gaming. Plus, its gorgeous curved OLED panel and ultra-wide aspect ratio could make it one of the best gaming monitors for immersive gaming in RPGs or strategy games.
I've tested this premium monitor for a few months now, and aside from a slightly steep (albeit not outrageous) price, I'm struggling to say much against it. Whether it's gaming, work or production, the Lenovo Legion Pro 34WD-10 OLED had me well and truly covered throughout testing. I'm just sad to be giving it back.
Anyway, for the complete lowdown, keep reading to see my full Lenovo Legion Pro 34WD-10 OLED gaming monitor review.

A crisp OLED panel, vibrant color, speedy performance and enough real estate to rear cattle, all wrapped up with typical Lenovo build quality — this monitor is a consummate all-rounder.
Alrighty, let's get into the most important stuff first. Paramount (for me at least) when testing any monitor are the subjective visuals. The 34WD-10 features a 1440p ultra-wide OLED panel, and it's gorgeous to behold.
1440p (or QHD) is the sweet spot in my opinion, at least on 27-34-inch monitors, giving you the perfect blend of resolution and detail without proving too taxing on your system. My rig uses a Radeon RX6900XT graphics card, which is capable of 4K UHD, but I've been able to run even intensive games at Ultra settings thanks to the lower QHD res.
That isn't to say it looks bad at all. At 34 inches, 1440p still looks fantastic, especially when we're talking about OLED. With OLED displays each pixel can turn itself off, giving super-dark blacks and rich contrast. I played a lot of S.T.A.L.K.E.R 2, a super dark and moody game, complemented superbly by the Lenovo's heavy blacks.
Colors are also nice and vibrant, even in Standard mode. I played Total War: Rome II and Valheim, both games with super-saturated warmer palettes, and they looked brilliant on the 34WD-10. The neon lights of Cyberpunk 2077, meanwhile, looked particularly fetching in the HDR Game modes, and the Warm sRGB SDR preset.
In addition to our subjective testing, we also run objective tests for color. You can see the results in the Lab Test tables below. We run these tests using our own calibrated color spectrophotometers.

Our Delta-E score tells us how close the color relayed on screen is to the color output from the source (i.e. the computer). The Lenovo's low score of 0.08 is very good, meaning this monitor is capable of rendering colors extremely accurately on screen. It isn't quite as accurate as the Alienware AW2725Q or the fantastic Alienware AW3425DW, but still pretty darn good.
The sRGB and DCI-P3 gamuts are two common color spaces. sRGB is a general-purpose SDR space and the most commonly used. At 156.40% coverage, the 34WD-10 has that entire gamut covered and then some, so it'll provide very accurate and vibrant color rendition for anything using that space — think web browsing, gaming, general media consumption, etc. This backs up my subjective findings in regards to bold colors.
DCI-P3 is a cinematic color space with a wider overall gamut than sRGB, so this color space generally gives a more accurate rendition of lifelike color than sRGB. Many movies and games specified as HDR are rendered in the DCI-P3 color space. Again, the Lenovo covers this whole gamut, plus extra, giving accurate and vivid performance in DCI-P3 / HDR.
In both color spaces, the Lenovo is only beaten in the table above by the Samsung Odyssey G9 and Alienware AW3425DW and AW2725Q — but at well over 100% coverage of both spaces, the 34WD-10 is still doing just fine.
The 34WD-10 features two DisplayPort 1.4 slots, although one is a USB-C DP 1.4 port. There are two HDMI 2.1 ports, one of which is eARC for hooking up to sound systems.
There's also a USB-C power cable with 140W pass-through, not to mention Ethernet, USB-C and USB-A charging ports. You can use the monitor as an all-in-one charging dock, like the Dell UltraSharp 40.
DisplayPort 1.4 allows for refresh rates of up to 240Hz at the maximum QHD resolution, which is perfect for fast-paced games and competitive first-person shooters. The 34WD-10 features a 0.03ms GTG response time. That means its pixels can change color in 0.03ms — on par with other high-end gaming monitors like the MSI MPG 272URX QD-OLED and Alienware AW2725Q. This reduces ghosting and motion blur, again giving a more responsive experience.
The monitor also features AMD FreeSync Pro and VESA Adaptive Sync, to reduce tearing and artefacts while gaming.
I partook in a few rounds of Counter-Strike 2 at 240Hz and enjoyed the smooth, blur-free experience. The high refresh rate/low response time also benefits less-intense gameplay, delivering buttery smooth action during fight scenes and horse chases in Kingdom Come Deliverance.
Typically, I wasn't able to achieve more than about 60fps in S.T.A.L.K.E.R 2, so that was a pretty choppy experience, comparatively speaking, but that isn't the monitor's fault — it's just a terribly optimized game (still).
The whole point of ultra-wide monitors is the space they provide. I've absolutely loved having the 34-inch 21:9 aspect ratio. I've had space for multiple windows on a single screen, which has been awesome for productivity, and stops me needing to drag windows onto my laptop screen. A single ultra-wide monitor is a viable replacement for two smaller monitors.
The wide aspect ratio and curved display are also great for immersion, enveloping you in the game you're playing. During RPGs like Kingdom Come Deliverance, S.T.A.L.K.E.R 2 and Cyberpunk 2077, I found myself totally immersed in the rich, detailed game worlds.
As you'll see in the Downs section below, brightness and glare reduction aren't this monitor's fortés. The curve, however, goes some way to redeeming this. The nature of the physical curve means that less light (and therefore glare) from lateral sources hits the display. My gaming setup is next to my window, and I've experienced less glare with the curved monitor than the flat IPS Dell monitor I was using previously, despite the Lenovo's lower brightness.
As one can usually expect from a Lenovo product, the 34WD-10 is built to a decent standard and feels like a premium product. The plastics used for the monitor body feel high quality, and I love the RGB lighting, which emanates a soft, unicorn-puke glow from the base of the monitor onto my desk.
My monitor came with a few stuck pixels, but that's relatively normal. At one point, it also developed a white line of hot pixels after a few hours on Kingdom Come Deliverance, but I simply ran an OLED refresh via the monitor's menu, which took care of the line and the stuck pixels.
The Lenovo Legion 34WD-10 also boasts some handy features, which I very much appreciated when using. Firstly, there are the OLED burn-in features I mentioned above. The OLED refresh came in super handy for clearing stuck pixels, and the monitor will prompt you to perform a refresh at 6 hours by default — you can set this to 8 hours or disable it.
There are a range of sRGB modes, too, which is useful if, like me, you edit photos. There's a neutral mode for a flat tonal profile, to avoid you under- or oversaturating images in the edit. There's also a DCI-P3 mode to edit video in that color space.
The Lenovo Legion 34WD-10's flaws are mostly to be expected from an ultra-wide premium OLED display: it's pricey, bulky and a little dim. I would've liked to see an Adobe RGB color mode, though, and there are cheaper (and better) rivals.
In the U.S., the Lenovo Legion Pro 34WD-10 costs $1,199 at Amazon or Lenovo. In the U.K., you're looking at £899. Don't get me wrong, I know that premium OLEDs cost money, but the 34WD-10 is priced as if it's a 4K QD-OLED, like the MSI MPG 272URX QD-OLED.
The longest nail in the 34WD-10's coffin, however, is the 34-inch Alienware AW3425DW — our favorite curved monitor — which matches or beats the Lenovo in almost every respect save Delta-E, yet costs just $799. And it's a QD-OLED, a more advanced OLED technology. There's really no justification for spending more on the Lenovo over the Alienware.
You can definitely find the 34WD-10 cheaper, and I've seen it sell for under the $1,000 mark, but that's still pricier than the Alienware.
In addition to our color testing, we also lab test monitors to measure peak brightness in SDR and HDR modes (if a monitor supports HDR for the latter).
Here are the 34WD-10's lab testing brightness results against key rivals.

OLED panels just aren't very bright when compared to IPS panels like the Sony Inzone M9 II, with its mega 936 Nits HDR peak brightness.
As far as OLEDs go, the 34WD-10 didn't perform badly, per se. In fact, the 34WD's peak SDR brightness is brighter than all the other OLED panels in the table above. HDR brightness is the lowest of the bunch, though, which is disappointing, and will potentially make this a poor choice for HDR gaming in brighter conditions.
As I touched on above, this isn't really a strong con, and more of a pre-purchase consideration. At 31.09 x 4.54 x 6.97 inches and 14.1lbs without its stand, the 34WD-10 is a big, heavy monitor. It proved a little irksome in our photo studio, as staff members had trouble moving it around after the shoot.
It wasn't easy for me to get onto my VESA arm, either, and I needed the help of a second person to do it without risking damage. Once on my arm and running, I also had to shift my desk around to accommodate the huge width of the panel, not to mention the added depth from the curve. That said, as I mentioned earlier, the monitor is wide enough that I no longer needed a second display in testing, so in an odd way, it actually proved space-saving.
This won't be applicable to everyone, and again, it isn't a strong con in a gaming monitor. However, if you're a photo editor, beware that the Lenovo Legion Pro 34WD-10 has no Adobe RGB color space mode.
If you're only editing casually and/or for online use, including social media, sRGB is fine. However, if you're doing lots of editing, especially for print, you'll want a monitor with an Adobe RGB mode, as this will ensure the highest color accuracy for your final printed shots.
I've really enjoyed testing the Lenovo Legion Pro 34WD-10 OLED gaming monitor. It's a stellar performer for gaming, with some super useful features, including acting as a 140W USB hub.
It put on an excellent performance in our color testing, and an average-for-OLED show in our brightness testing. Gaming at 240Hz was super smooth, and with the vivid colors and high contrast you'd expect from a premium OLED display.
At full price, though, it's difficult to recommend the 34WD-10 over the awesome Alienware AW3425DW, which is why I can't award the Lenovo 4.5-stars and our coveted Editor's Choice award. Does that mean I want to give it back to Lenovo, though? Not at all.

How AI, Creators And Sports Are Shaping Marketing's Next Chapter
Emily Ketchen | Chief Marketing Officer & SVP, Intelligent Devices Group & International Markets at Lenovo | Global Marketing Executive. It's hard to believe that another year of the Cannes Lions International Festival of Creativity has come and gone, and I was fortunate enough to attend for a third consecutive year. Cannes is always a flurry of activity, from different sessions to panels to the judging and awards. But above all, it's a unique time when you can find some of the greatest minds in marketing in the same place. That's how I like to view it. Each year, I approach the festival with two goals: to share what Lenovo is doing to bring smarter technology to all and to gather new insights that can guide our future marketing. This year was no different, as there were so many opportunities to exchange ideas and learn from our peers. Here are some of my top takeaways from this year and what they reveal for the future of marketing. Marketers' confidence in AI lends to boosted creativity. Even as creative industries increasingly use AI to help inform their work, it's important to remember that it's people, not AI, who are creative. Creative spirit, talent and timely cultural relevance can't be replaced by AI, but creatives must be willing to explore AI as an important tool that can maximize their work through refinement and customization. This greater understanding of how to effectively use AI was evident as brands used the technology in more compelling, smarter ways across campaigns. An award-winning campaign like Dove's 'Real Beauty,' which used AI to reprogram Pinterest's algorithm to prioritize natural and inclusive beauty over AI-generated images, illustrated how AI can be used purposefully within a marketing mix to breathe new life into a long-standing, purpose-driven campaign that's relevant for the modern era. Brands' internal frameworks around AI were also discussed in relation to how they support marketers to become more confident AI users, so they can create, experiment and collaborate with the right AI knowledge, tools and guardrails in place. Rather than superficial and ad hoc experimentations of AI, we've seen how marketers' maturing AI proficiency is leading to bolder marketing that also demonstrates how it can be used for good, which goes a long way in building trust with consumers around AI and drives business forward. The creator economy is growing stronger. Creators were at the forefront of this year's discussions, being positioned as much more than just amplifiers for traditional influencer marketing. They are now viewed as strategic cultural partners who contribute creative ideas, co-develop content and even shape brand narratives from ideation to execution. As a nod to this shift, Cannes rebranded its 'Social & Influencer Lions' into 'Social & Creator Lions.' They also introduced various subcategories to address topics such as culture, social content marketing and social insights. There was an increase in both creators and campaigns alike. Vaseline Verified, for example, where more than 450 creators (registration required) shared hacks and different uses for Vaseline, went on to win the Health and Wellness Grand Prix. This increased presence shows how important the creator economy is in amplifying brand relevance and trust. By leveraging a creator's authenticity, relatability and influence, brands can foster genuine connections with consumers. Sports are playing a bigger role in marketing than ever. The role of sports in marketing is certainly nothing new. The sports sponsorship market is expected to reach $115 billion in 2025, but it has gained increased popularity at the festival, particularly as sports like Formula 1 take off as cultural phenomena in the U.S. At Stagwell's annual 'Sport Beach' at Cannes, the tech and innovation track examined how technology is changing consumer interaction with sports, such as wearables, augmented reality and data analytics and visualization. That fusion of sports and technology is reshaping not just what fans experience, but how teams think, react and compete—allowing fans to become interactive participants and turning stadiums into smarter ecosystems. Sports partnerships were also discussed in how they present unique opportunities to further build brand trust by putting your product (and subsequently your brand) right in front of customers. This helps showcase technology solutions that enhance the fan experience while meeting consumers where they are and presenting the opportunity to demonstrate confidence in a brand's technology. At Lenovo, we've experienced this firsthand through our multiyear partnership with Formula 1, one of the most technologically advanced sports in the world. A Glimpse Into Future-Ready Marketing The conversations, campaigns and collaborations at Cannes Lions proved that the convergence of AI, creators and immersive sports partnerships isn't a trend—it's a new playbook. To lead in this era, marketers can work to embed AI intentionally to enhance creativity and build trust, elevate creators as true co-developers of content and harness the cultural power of sports to drive brand relevance. Cannes Lions is a powerful yearly reminder that bold, culturally attuned, tech-enabled storytelling is no longer optional—it's the price of entry, and something I'll take into the next year. Forbes Communications Council is an invitation-only community for executives in successful public relations, media strategy, creative and advertising agencies. Do I qualify?
