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.

[Watch the video to see the issues I'm having! Don't know if it's just me so I'm basing this review off of my experience.] The monitor was awesome! No bulky frames, decent screen quality for the price, and 144hz! It was all I wanted in a monitor for a cheap price. I decided to keep it and go past return date. Only 2 weeks later (now) it can only perform 60hz due to the fact it cuts in and out on 144hz, 120hz, etc. Static lines, full static, static cutting in and out, the monitor is practically unusable on a frame rate higher than 60hz. Sure it's still usable, still that decent screen quality and small borders, but I didn't spend almost $200 for a monitor that only functions on 60hz. Don't listen to the reviews, the monitor is wonderful and great for the price but it'll stop working before you know it. Buy from a different brand if you want a monitor that lasts.

I have been using this monitor for several weeks now. My initial impressions are positive. I chose to go with an IPS Mini LED monitor, rather than a OLED, due to concerns about longevity and burn in, and because the mixed use I typically do leans heavily on the productivity end of the spectrum. Color accuracy and range is quite good, with satisfactory factory defaults. Switching from an expensive, but aging IPS monitor with excellent color accuracy, that was my biggest concern with the Koorui S2741LM. Fortunately this monitor delivers on the manufacturer's claims. The 160Hz refresh rate is huge step up from the 60Hz on my old monitor, and even in general productivity work it's a noticeable improvement. Using HDR while playing games or watching a movie is impressive. It's also possible to manually turn on local dimming and increase brightness without HDR, which is nice for apps that don't work consistantly in HDR mode (looking at you Plex windows app). I'm sure that a side-by-side comparison with an OLED would show the mini LED's shortcomings, but I don't regret the choice at all. I find the "low" setting works best for me, and benefits from increasing brightness significantly. This is where my primary complaint comes in. Windows has an HDR mode shortcut (win-alt-b), but to manually switch to local dimming requires diving into the OSD, and tweaking brightness settings. That's quite cumbersome. I will typically switch between productivity work where local dimming needs to be off, to full screen video and gaming, where local dimming shines, multiple times a day. Rather than having a dedicated button to switch screen resolutions, I would have preferred to have a button that could switch between two user customizable modes. I was a little disappointed to discover that the monitor comes with a large power brick. It would have been nice if the manufacturer integrated the DC inverter into the monitor. On the other hand, the monitor does come with a full assortment of cables, which was nice. Screws were also included for VESA mounting, so finding screws of the right depth was not necessary to get the monitor attached to my desk mount. Overall I've found the Koorui S2741LM to be an excellent monitor. Local dimming with over a 1000 dimming zones delivers the gaming and movie experience I was looking for, and monitor's the color accuracy and range are good enough for occasional image and media work.

was a decent monitor but only lasted 1.5 years until, it started split-screening. Tried hooking up hdmi to different ports and using a different cable, but no fix. Wouldn't buy again.

I really liked this monitor. Great picture, however it failed at around 6 months of daily use. It went blank. contacting manufacturer didn't work even though it had a 3 year warranty. They never contacted me back even though I used their contact page twice. After some frustration with the Amazon chat process and then calling Amazon on the phone, which was frustrating as well due to poor english speaking phone support persons, I did get a refund. All is well in the end, but several times being told what to do then I should hear back in 24 to 48 hours and nothing until calling on the phone, which was then frustrating. Update. after almost 2 weeks I hadn't received a refund. I called amazon support again and had to go over the whole story again. They advised a refund had been issued, however they didn't make it to the card I used for this transaction. They made it to a card I hadn't used with Amazon in several years. Another call over 12 minutes of my time, however the refund did happen. Just not to the right account.

This monitor was great until it went out less than a year into owning it. There was no recourse for me so I tossed it. Stick to name brands with a repair or return policy.

Easy setup. I do not game so this is strictly for work and browsing the internet. Fast refresh rate. I do not find that the image is a clear and sharp as my older ACER XF270HU monitor which finally gave out on me last week. No way to adjust anything with the HDR setting, display wise, which is, by far, the sharpest image for this monitor. For the price, it's a decent buy.

I have purchased 4 of these monitors, both because of the low price and the decent size of the screens. I use two of them for my home office where I previously only used my 15 inch laptop. Looking back now, I don't know why I did not upgrade sooner. I just love the added screen real estate for my work. It has made a big difference in completing my work sooner where I no longer have to click alt+tab to switch between screens as I constantly did on my laptop. I don't really use these screens for gaming but the video quality looks great to me. The one complaint I have is that they are very fragile. My son has one of these screens in his room and when he got upset at me for telling him to do his homework, he tossed a pencil at the screen. I kid you not the screen stopped working. As you can see from the picture, the star shaped area is where the pencil struck the screen and ruined the whole screen. Now, the pencil did not break the screen because there is no glass to break. The pencil damaged one part of the screen which I guess affected the entire screen. I was there when my son tossed the pencil so it was not like throwing a ball, but I guess it hit the screen just right where it made the entire screen unusable. However, absent any tantrums at home, you should be happy with these screens. Just make sure to handle them with extra care.

El monitor cumple su función pues da la resolución 1440p pero lo hace a 8 bits y es bueno. El panel es VA lo cual para algunos no les gusta sin embargo vale la pena comprarlo y más por el precio pues yo lo agarre en oferta un poco abajo de $4000. Este es el primer monitor que uso para jugar ocasionalmente y ver películas. El único inconveniente que no se si solo me suceda a mi es que a veces cuando veo algo en Netflix la pantalla corta una parte del video y despues de 1 o 2 segundos vuelve la imagen, normalmente donde van los subtítulos pero solo sucede con esa plataforma; PARA JUGAR VA DE MARAVILLA.

Nice
