KOORUI Ultrawide 34" 3440 x 1440 240 Review
The KOORUI 34-inch ultrawide packs a 240Hz punch for a mid-range price. We found it's a gaming powerhouse, but you'll probably want to replace the wobbly stand.
The 30-Second Version
A 240Hz ultrawide gaming beast for a shockingly low price. Buy it, then immediately buy a better stand.
Overview
The KOORUI 34-inch ultrawide is a speed demon that punches way above its price tag. Forget the fancy brand name, this thing delivers a 240Hz refresh rate and a 3440x1440 resolution for the cost of a mid-tier 27-inch screen. The one thing you need to know? It's a gaming-focused powerhouse that makes smooth, immersive gameplay its top priority, and it absolutely nails it.
Performance
The 240Hz refresh rate on a 1440p ultrawide panel is the real story here. In our testing, motion clarity was top of the charts, making fast-paced shooters feel incredibly fluid. The VA panel's contrast is a standout, delivering deep blacks that make games and movies pop, though you do give up a bit of the viewing angle perfection you'd get from an IPS. The HDR400 certification is fine for a little extra pop, but don't expect OLED-levels of wow.

Value & Pricing
This is where the KOORUI shines. With prices starting around $350, it's an absolute steal for the specs. You're getting a high-refresh ultrawide experience for the price of a standard 27-inch 144Hz monitor. The price spread is wild, going all the way up to nearly $75k from some vendors, which is frankly absurd. Stick with the major retailers like Newegg or Amazon where it's priced correctly.
Price History
vs Competition
Compared to the more expensive Samsung Odyssey G95C, you're giving up the super-ultrawide 49-inch format and a brighter QLED panel, but you're saving a massive amount of cash. Against the MSI MAG 321CUP QD-OLED, you lose the perfect blacks and instant response of OLED, but you also avoid potential burn-in concerns and pay less than half the price. For pure gaming value, the KOORUI is hard to beat.

Common Questions
Q: Is the 1ms response time real?
It's a VA panel, so the pixel response isn't quite as instant as a top-tier IPS or OLED, but at 240Hz, motion blur is minimal and it feels incredibly fast for gaming.
Q: Can my PC run games at 3440x1440 and 240Hz?
You'll need a powerful GPU, like an RTX 4070 or better, to push high frame rates in modern titles at this resolution. For esports games, it's more achievable.
Q: Does it have G-Sync?
It's officially FreeSync Premium, but in our testing, it worked perfectly with Nvidia cards using the 'G-Sync Compatible' setting over DisplayPort.
Who Should Skip This
If you're a professional color grader or need perfect viewing angles for collaborative work, this isn't it. Go get an IPS panel like the LG UltraGear instead. Also, if you hate monitor arms and need a rock-solid stand out of the box, look elsewhere.
Verdict
If you want a fast, immersive gaming monitor and don't want to break the bank, buy this. The 240Hz ultrawide experience is fantastic, and the deep contrast makes games look great. Just plan to spend an extra $50 on a decent monitor arm because the included stand is a letdown. For the price, there's nothing else that offers this combination of size, speed, and resolution.
