  • Koorui 34E6UC (34" 3440×1440, 180 Hz, 1000R curved VA panel) — But Missing Info Buyers Should Know
Size: 34"/WQHD/1000R/HDR400
Review: I purchased two of the Koorui 34‑inch curved ultrawide monitors for a dual‑monitor setup, and so far I’m very pleased with them. The picture quality is sharp, the brightness is solid, and the “Normal” color preset looks natural without any adjustments. For the price, these 34‑inch panels deliver very good performance. That said, there are a few important details the product listing and reviews don’t mention — and knowing them ahead of time would have saved me some stress during installation. 1. YES, the 34‑inch model DOES include stand‑offs (spacers) This is not mentioned anywhere in the listing, and even Amazon’s Rufus incorrectly says they are *not* included. They actually come in the small accessory packet with the manual. If you’re mounting these monitors, you will need those stand‑offs because of the recessed VESA pattern. They are already in the box — just not advertised. I rushed to order a separate spacer kit because the listing didn’t mention it, so I’m putting this here to help the next person avoid that. 2. One of my monitors flashed briefly until I disabled FreeSync On one of the two monitors, I noticed a quick bright “flash” when moving the mouse. Turning off Adaptive Sync / FreeSync in the monitor’s menu fixed it instantly. The other monitor didn’t have this issue, so it seems to vary by panel. Not a defect — just something to be aware of if you see flicker or brightness pops. 3. Color and brightness match well once set manually After setting both monitors to the same brightness, contrast, and color mode, they match very well side‑by‑side. The “Normal” color preset looks the most accurate on these VA panels. 4. Build quality and packaging are solid Both monitors arrived well‑protected, and the included cables work fine. The stand is basic, but I’m using monitor arms, so that wasn’t a factor for me. 5. Too early to comment on long‑term support or durability I’ve only had these monitors set up for a few hours, so I can’t speak yet to long‑term reliability or how responsive Koorui’s support is. I’ll update this review if anything changes over time. Bottom line: These 34‑inch Koorui ultrawides are excellent for the price, especially for gaming or a dual‑monitor setup. Just be aware that: - Stand‑offs ARE included (despite the listing not saying so) - FreeSync may need to be turned off on some units - Picture quality is great once you match settings manually - Long‑term support is still unknown If the listing had mentioned the included spacers, it would have saved me a last‑minute order — so I hope this review helps the next person. ... show more

  • Awesome monitor! (my 3 year review)
So I've owned this monitor for about 3 years now and here's what I have to say about this monitor. The picture quality is actually really good. I got the 1080p version and I mostly use it with my Xbox series x and occasionally will use it for some lighter gaming on my gaming PC both work effortlessly well. The screen size is okay I think next time if it's in the budget I'll buy there 34 inch curved monitor. But for right now I'm sticking with this monitor until it dies and so far it's running strong 3 years later. Right now this monitor cost $80 which is an absolute steal at that price. I paid $130 for it and would say it's absolutely worth getting. There's no flickering. The setup process went smoothly. It's compatible with both my console and gaming PC! I absolutely love this monitor! I don't own the 27 inch version but I'd recommend going with either that size or bigger if you can afford it. ... show more

  • It REALLY is a 4K monitor.
Size: 27"/UHD/IPS
Today I set up my dual KOORUI 27" model N07 monitors. I was somewhat worried by multiple reviewers reporting that this model isn't really a 4K screen. So while I don't usually write reviews, I'm here to assure you the N07 is in fact a 4K screen with resolution of 3840x2160 and refresh rate of 60hz. And I know why some people got this wrong. When I unplugged my old 1920x1080 monitors and tried to use the same HDMI cables, Windows identified the monitor as having a 1920x1080 native resolution. But my cables were very old. I plugged both my new monitors in using DisplayPort cables and they were instantly reporting 3840x2160. My monitors did not come with DP cables, just new HDMI cables. But my office had extra DP cables laying around. If you're still having trouble getting 4K on one of these, be wary of adapters, such as DP-to-HDMI, DVI-to-HDMI, etc. Also try shorter or newer cables. You CAN get 4K out of HDMI cables, but remember that HDMI has been around since 2002 and that standard has gone through many versions with new capabilities over the years. As for reviewing the other aspect of these monitors... they look great to me! Neither of mine had dead or stuck pixels. the colors look good and image is sharp. I'm not a professional monitor reviewer, but these seem like perfectly good office monitors for a fantastic price compared to big brand names. I took a chance on some of their smaller screens several months back and was blown away at the quality and low price. I'm glad this higher end model hasn't let me down! UPDATE: My original review was written 10/13/2023 and now it's 5/16/2025. I have never had a single issue with these monitors in the 1 year 7 months I've been using them. In fact I stumbled across my own review after looking to purchase a 3rd matching one... because a triple-monitor setup with these bad boys would be awesome! By the way, I use them on a dual-monitor desk mount. I love that they have VESA mounting holes so they can be used on wall or desk arms/mounts. ... show more

  • Smooth Performance, Great Colors for the Price
Size: 24inch/200hz/IPS
Excellent value for the price. Runs super smooth during my workflow and the colors look sharp and vibrant. The high refresh rate makes everything feel responsive, and it’s great for both work and casual gaming. Solid monitor if you want performance without overspending.

  • Good Monitor, Check Images for how to mount on overly large VESA brackets
Size: 34"/WQHD/1000R/HDR400
Only had it a few days, will update this review in a year. Very pleased with this monitor, works great, and sound through the HDMI via my very old GFX card works well. Overall just extremely pleased, this replaced two older heavier monitors. I have attached pictures on how the to use this with a VESA bracket that is overly large. The monitor comes with extension bolts / screws to allow the bracket the clearance needed. ... show more
