And for the asking price, it's major worth for the price you pay. A 34" incher with a 4K wide res, along with software simulated HDR is actually amazing for this price. The monitor is almost identical to the Samsung G5, and has almost similar specs, but in some ways I feel are better. It has punchier colours as well. Overall, incredibly worth the price. Review: Check your cables and settings. - I hesitated buying this because a few reviews said it was not really 165hz but only 100hz but I rationalized that 100 was better than 60 anyway and the price is too good. I can now say it is a phenomenal screen for pc gaming, and yes if you use an HDMI cable chances are you will be limited to 100-120hz but the screen comes with a DP cable, which will give you 4k@165hz, for tv HDMI will be fine but if you game with a console or PC, use the DP cable to get the higher refresh rate and to utilize the screens FreeSync. Also check your pc settings like nvidia control panel to set the refresh rate. Awesome screen for an awesome price. ## Features - 4K Monitor - Gaming Monitor - 21:9 Monitor - HDR 400 Monitor ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CFQ6KSPL | | Adaptive Sync | FreeSync Premium | | Additional Features | Curved | | Aspect Ratio | 21:9 | | Aspect ratio | 21:9 | | Best Sellers Rank | #6,692 in Computers ( See Top 100 in Computers ) #206 in Computer Monitors | | Brand | KOORUI | | Brightness | 273 | | Color | Black | | Compatible Devices | Computer | | Connectivity Technology | HDMI | | Country of Origin | China | | Customer Reviews | 4.3 out of 5 stars 94 Reviews | | Display Resolution Maximum | 3440 x 1440 | | Display Technology | LED | | Display Type | LED | | Hardware Connectivity | HDMI | | Has Color Screen | Yes | | Item Dimensions D x W x H | 15.3D x 80W x 54H centimeters | | Item Weight | 8 Kilograms | | Manufacturer | KOORUI | | Model Name | 34E6UC | | Model Number | 34E6UC | | Mounting Type | Wall Mount | | Native Resolution | 3440x1440 | | Number of Component Outputs | 1 | | Picture Quality Enhancement Technology | HDR 400 | | Refresh Rate | 165 Hz | | Resolution | 4K | | Response Time | 1 Milliseconds | | Response time | 1 Milliseconds | | Screen Finish | Glossy | | Screen Size | 34 Inches | | Screen size | 34 Inches | | Screen surface description | Glossy | | Shape | rectangular | | Specific Uses For Product | Gaming | | Total Number of HDMI Ports | 1 | | Warranty Description | 1 year warranty | | Warranty Type | 1 Year Manufacturer Warranty | ## Product Details - **Aspect ratio:** 21:9 - **Brand:** KOORUI - **Resolution:** 4K - **Screen size:** 34 Inches - **Screen surface description:** Glossy ## Images ![21:9 WQHD 3440 * 1440 4K （HDR 400）34 Inch 1800R Curved Gaming Monitor, 165Hz MPRT 1MS (AMD FreeSync Premium Nvidia G-SYNC) Hdmi DP 90% DCI-P3 OSD Roker Computer Gamer Monitors - Image 1](https://m.media-amazon.com/images/I/71e+o5GD7aL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Incredible product, even more incredible price! *by E***A on 7 April 2025* This monitor is actually incredible. And for the asking price, it's major worth for the price you pay. A 34" incher with a 4K wide res, along with software simulated HDR is actually amazing for this price. The monitor is almost identical to the Samsung G5, and has almost similar specs, but in some ways I feel are better. It has punchier colours as well. Overall, incredibly worth the price. ### ⭐⭐⭐⭐⭐ Check your cables and settings. *by J***E on 28 December 2024* I hesitated buying this because a few reviews said it was not really 165hz but only 100hz but I rationalized that 100 was better than 60 anyway and the price is too good. I can now say it is a phenomenal screen for pc gaming, and yes if you use an HDMI cable chances are you will be limited to 100-120hz but the screen comes with a DP cable, which will give you 4k@165hz, for tv HDMI will be fine but if you game with a console or PC, use the DP cable to get the higher refresh rate and to utilize the screens FreeSync.

It also provides good support for Ray Tracing and HDR features. However, a drawback is the overly intense red color, which requires adjustment. Unfortunately, when HDR is enabled, you lose the ability to modify the colors, which can be frustrating. Overall, it's a solid display for gaming, especially with its PS5 Pro and HDR capabilities, but be aware of the color calibration limitations. ## Frequently Bought Together - KOORUI 21:9 WQHD 3440 * 1440 4K （HDR 400）34 Inch 1800R Curved Gaming Monitor, 165Hz MPRT 1MS (AMD FreeSync Premium Nvidia G-SYNC) Hdmi DP 90% DCI-P3 OSD Roker Computer Gamer Monitors - Gaming Desk with LED RGB RC Light,Z Shaped for Pc,Blue120×60×75cm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/549962130-21-9-wqhd-3440-1440-4k-hdr-400-34-inch](https://www.desertcart.jp/products/549962130-21-9-wqhd-3440-1440-4k-hdr-400-34-inch) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-10*
