KOORUI Shipped a 1152-Zone Mini-LED 4K 160Hz Monitor for $694, and Reviewers Mostly Buy It

What it is

The KOORUI S2741LM is a 27-inch dual-mode Mini-LED IPS gaming monitor. It runs at 4K UHD (3840x2160) at 160 Hz or FHD (1920x1080) at 320 Hz, with a switch in the on-screen display. The backlight has 1152 local-dimming zones, 1 ms gray-to-gray response, HDR1400 certification, 99% Adobe RGB coverage, 90W USB-C power delivery, HDMI 2.1, DisplayPort 1.4, and VESA 100 x 100 mount.

Pricing is $694 on sale from $878 MSRP on Amazon US, and £399.99 on Amazon UK. The UK price is a significant discount vs. US pricing and suggests retail volatility ahead.

What's interesting

1152 dimming zones at 27 inches is genuinely class-competitive. The Samsung Odyssey Neo G8 and LG 27GR95QE-B sit at similar zone counts but at prices that start above $1,000. KOORUI's sell is that they shipped the same fundamental technology stack at a lower price.

Dual-mode gaming is the niche the S2741LM is chasing. At 4K 160 Hz the monitor is a content-creation and single-player gaming display with sharp pixels and accurate color; switched to FHD 320 Hz, it becomes a competitive-shooter display with framerate headroom. RTINGS confirmed the mode switch is clean (roughly 2 seconds to re-handshake) and both modes hit their claimed refresh rates.

HDR1400 is the other flex. The certification requires sustained 1400 nits peak brightness in a 10% window, which on an IPS Mini-LED display means HDR content has real dynamic range. PCMonitors measured peak brightness at 1450 nits, matching the claim.

90W USB-C power delivery turns this into a one-cable MacBook or Windows laptop dock. The included Type-C cable carries display, data, and charging. For anyone who works on a laptop and games on a desktop, this is a meaningful workflow win.

What's missing or unverified

KOORUI is not a long-established display maker. The brand has been selling on Amazon since 2020 and has built up roughly 40,000 reviews across its lineup. Warranty handling and long-term firmware support remain unproven compared to Samsung, LG, or Dell UltraSharp.

Mini-LED local dimming introduces blooming around small bright objects on dark backgrounds. RTINGS measured noticeable blooming on subtitle text and bright UI elements at night. OLED monitors have no blooming; for desktop icon work in a dark room, an OLED alternative (LG 27GR95QE or Asus PG27AQDM) is a cleaner visual experience at the same price.

Color accuracy is factory-calibrated to 99% Adobe RGB but there is no sRGB emulation mode and no DCI-P3 clamp. For color-managed workflows the monitor needs a calibrator and a custom profile. Review-Rating confirmed uniformity was within 3 delta-E across the panel, which is acceptable but not professional-grade.

Who it's for

Dual-purpose home-office buyers who game one hour and work six hours on the same screen. Competitive FPS players who want 320Hz FHD when it matters and 4K sharpness otherwise. MacBook or Windows laptop users who want a single USB-C cable that drives display and charging.

Not for: color-critical creative pros (get a Dell UltraSharp U2725QE or BenQ PD2725U), competitive gamers who need OLED response times, or buyers who want a brand with 15+ years of monitor track record.

Verdict

The S2741LM is the monitor that answers "what if the Samsung Odyssey Neo G8 cost $694 instead of $1,300." The spec match is close, the panel performance is close, and the brand risk is the primary reason to hesitate. For a gamer-and-creator who wants Mini-LED HDR and dual-mode refresh rates without paying flagship prices, this is the most aggressive value pitch in the segment. For a buyer who wants the best-established brand with the best warranty story, Samsung or LG remains the pick.
