KOORUI S4941XO 49" Black 2025

The KOORUI S4941XO is a 49-inch OLED gaming monitor that pairs a 5120x1440 resolution with 240Hz and FreeSync Premium, all for around $1300. It puts up elite performance numbers and undercuts the Samsung G9 by a significant margin, though its SDR brightness is quite dim. If you're after an ultrawide OLED for immersive gaming and can live with the caveats, it's one of the best deals in the category.

If you're hunting for a massive OLED gaming monitor without spending north of $1500, the KOORUI S4941XO might stop you in your tracks. It's a 49-inch super-ultrawide with a 5120x1440 resolution, a 240Hz refresh rate, and a near-instant 0.03ms pixel response, all wrapped in a deeply curved 32:9 panel. That spec sheet reads like a dream for sim racers and anyone who wants to fully replace a dual-monitor setup with one seamless display. KOORUI isn't a household name yet, but they've packed DisplayHDR True Black 400, FreeSync Premium, and a generous USB-C port with 90W charging into a package that currently sells for about $1300. The 98th-percentile display and performance scores from our database put it among the absolute best ultrawides right now, especially if gaming and cinematic entertainment are your main gigs. But a few trade-offs, like modest SDR brightness and barebones ergonomics, keep it from being a no-brainer for everyone.

Gaming on this monitor is a treat. The 240Hz refresh combined with the OLED's blazing pixel response makes motion look impossibly clear, even in fast shooters. It's not quite the 500Hz you'd find on top-tier esports screens, but for a super-ultrawide, it smooths over nearly every type of ghosting you'd notice with a typical VA panel. FreeSync Premium works flawlessly with both AMD and modern Nvidia cards, so screen tearing is a thing of the past. We benchmarked the S4941XO's motion handling and input lag against other gaming monitors, and it sits in the 98th percentile for performance, genuinely one of the best on the market. The catch? You'll need a seriously powerful GPU to push 5K-ish pixels at high frame rates. Even an RTX 4080 will sweat in demanding titles, but you can always drop to 3840x1080 or use DLSS to keep things above 100fps if your card can't hang.

At $1300, the KOORUI undercuts the Samsung Odyssey OLED G9 by a few hundred dollars while delivering an almost identical core experience. That's a meaningful gap if you're stretching your budget for a flagship display. You do miss out on Samsung's smart TV features, a more refined OSD, and arguably brighter HDR highlights, but those differences shrink when you just want a gigantic, responsive panel for gaming. For the money, it's a standout value in the super-ultrawide category, though we'd love to see a lower MSRP become the norm as OLED yields improve. If you find it on sale for less, it's a steal.

The most direct rival is the Samsung Odyssey OLED G9 (G95SC), which uses a very similar 49-inch QD-OLED panel, 240Hz refresh, and 0.03ms response. Samsung typically costs more but adds a glossy screen coating, built-in speakers, and a smart hub for streaming. Both are neck-and-neck on gaming performance, so the KOORUI's main advantage is pure price. If you'd rather have a smaller, brighter HDR experience, the Alienware 34" QD-OLED curved monitor is a stellar choice, peaking around 1000 nits in HDR and often well under $1000 on sale, but you lose that extra horizontal real estate. On the other end, the ASUS ROG Strix XG27AQDMG and MSI MAG 272UP QD-OLED are 27" flat alternatives with even higher peak brightness and faster response, but they're not ultrawide at all. The KOORUI sits right in the middle: it's the budget 49" OLED for people who want the immersion without the Samsung tax.

Skip the KOORUI S4941XO if your desk isn't at least 30 inches deep, or if you work in a brightly lit room where 250 nits of SDR brightness will look washed out. Hardcore esports players who only need 24-27 inches and 360Hz+ should look elsewhere too. And if you demand a mature set of smart features, integrated speakers, or a full USB hub, the Samsung Odyssey G9 or an Alienware QD-OLED will feel more polished. For those who want a more versatile HDR experience with punchy brightness, consider a 34-inch ultrawide QD-OLED instead.

If you have a deep enough desk and a GPU that can drive 5120x1440 at playable framerates, the KOORUI S4941XO is a phenomenal way to dive into super-ultrawide OLED gaming. It delivers best-in-class motion clarity and those jaw-dropping inky blacks that make open-world games and space sims sing. Just know that you're trading away high SDR brightness and a polished ecosystem for that lower price tag. For pure gaming and entertainment in a dark room, it's hard to fault. Buy it if you value immersion over peak nits, and you'll be grinning every time you fire up a game that supports 32:9.
