Great Budget Gaming Monitor with Sharp Picture and Smooth Performance
I purchased this 27-inch curved gaming monitor and have been very impressed with it, especially for the price. The QHD resolution makes everything look crisp and clear, whether I’m working, streaming, or gaming. The 144Hz refresh rate provides smooth motion with no noticeable lag, and the curved screen adds a more immersive feel without being overwhelming.Setup was quick and easy, and the monitor feels much more premium than I expected. Colors are vibrant, text is sharp, and the size is perfect for both productivity and entertainment. I’ve used monitors that cost significantly more and honestly don’t see enough difference to justify spending extra.If you’re looking for an affordable monitor with excellent picture quality, smooth performance, and a sleek design, this one is a great value. I would definitely purchase it again.

HDR goodness
I am coming from an IPS Predator panel. I didn't chose to buy this screen because of picture quality but because I wanted a higher resolution. Coming from 1080P, so this one was within my price range. Also wanted HDR whereas my last panel didn't support it. I've been using this one for a day and a half and I must say it's eye opening what I was missing out on. Also a lot of misconception regarding miniled panels. The picture quality is just as good and even BETTER than the predator it replaced. The 180hz refresh rate is less than the 240hz it replaced but I can't notice any difference, no input lag or ghosting at all. Smooth and clear. The brightness of this screen with HDR enabled is INSANE, you just don't know what you are missing until you have tried true HDR. The colors in SDR isn't as good as my IPS panel but once you turn on HDR the colors are better than my predator monitor and insanely bright. If you find it too bright you can turn it down to whatever level pleases you. The 1152 lighting zones give this miniled a HUGE bonus to darks and bright images. Meaning very deep blacks and bright brights! I have a fairly new OLED TV and I can't see any difference between the two technologies. The color options in HDR is greyed out so you can't adjust it but I can see why this is the case. It doesn't need any adjustment at all... The colors are fantastic in HDR. To keep all the goodness of HDR not just while gaming you can turn it on for windows operating system as well. I turned it on for everything. I really did not understand what a huge difference HDR makes. Ran some identifying software Aida, and says it's putting out over 1500 knits brightness in HDR. Games just look 100% better with HDR it's no contest. I'll never go back to non HDR viewing. 1440P is the sweet spot for gaming and navigating windows. Even when HDR is on you can adjust the brightness to your liking. You will have to make certain adjustments for this panel in terms of contrast but I made all the changes within the first few minutes. Also has game setting for boosting smoothness but it's refresh rate of 180 hz is more than good enough by itself. Well done KTC for getting consumers what they want. No frills monitor and great quality!

Fast, good quality
I had two 27" Dell curved gaming monitors before this. I now work from home and needed two flat, smaller monitors that are easier to view and that can change direction more easily. These worked out perfectly and have a great screen. I didnt realize how different it would be going from curved to flat screen, but it will make working so much easier. Setup was easy- i didnt even glance at the instructions. The DC cables they came with are much more easy to manage than the bulky power cables im used to from monitors. Also I wasnt expecting the DP cables to be included so that was a nice surprise. Great monitors at a great price.

Excellent monitor with some tweaking read full review
Excellent monitor, but a little too saturated on default settings out of the box. For the best experience, either use sRGB mode with low local dimming at 75% or 100% brightness, or, like I do, and use DCI-P3 color mode with low local dimming at 100% brightness, and it looks really accurate and great!As for HDR, it's a mixed bag. In order to get the best brightness and bang for your buck, you shouldn't be using this monitor with Windows HDR or macOS. If you want true 1:1 HDR, it is much better with a console that has proper HDR settings and out of the box tuning. But if you want to use it with a PC or Mac, it is still mostly fine, but I would calibrate the HDR using the built-in calibration in Windows.The refresh rate is also a mixed bag. If your computers GPU or console doesn't support the latest DP 1.4 and/or HDMI 2.1 standard, then you won't be able to do more than 120Hz at 4K without display compression, and it looks and feels horrible when compression is on and visable at 160hz.My recommendation is this setup for PC:Use the DCI-P3 color mode for the best color accuracy across HDR and SDR, but if you don't plan on using HDR and use exclusively SDR, then stick to sRGB mode for the best accuracy for SDR content and gaming.100% brightness for the best brightness and hitting the advertised HDR brightness claims. Note this may be too much for the average person, so if that's the case, stick to 75%, which still hits a respectable brightness. For HDR calibration in Windows: set to 1930 nits (small window) and 1600 nits (full screen), as those are the official rated numbers. Use exclusively 120Hz at 4K and the standard preset for overdrive, as any other preset has overshoot and ghosting and any refresh rate above 120hz is pointless if you get display compression and not that noticable or helps much in gaming.As for the 320Hz dual-mode operation, it does not support native scaling, so you just get a blown-up 1080p image with no scaling, and it looks very blurry and unclear on the 4K display. It does hit its advertised 320Hz, but it is unusable in my opinion due to the blurriness of the picture from the lack of proper image display scaling. I also think they are slightly overdriving the pixels more than usual because even on the standard preset, there is still a lot of visible ghosting and overshoot on the monitor. I had to fully turn it off to get rid of it, but that defeats the point of the 320Hz mode, as it introduces more input delay for a clearer, smoother image. If you bought this monitor purely for the 320Hz mode and don’t plan to use 4K, you would be better off with a monitor that has native 320Hz support. This is clearly more of a 4K monitor than a 320Hz 1080p one.In conclusion, if you are looking for an excellent 4K monitor with really bright colors and overall brightness for viewing content and gaming in HDR, then this is it. But if you are looking for the best response times and don’t want to tweak settings out of the box, then maybe look for something else, as this monitor is clearly aimed at MiniLED enthusiasts and people who know what they are buying and how to properly set it up for the best experience. If you want a great MiniLED thats for beginners I recommend the AOC Q27G3XMN 27" for a better entry point to gaming with a MiniLED as it's 1440p and doesn't need any tweaking out of the box for a great experience if you want to try out MiniLED without eating away $500.

Great display, unbeatable value
This miniLED monitor is phenomenal, and gives you a lot of functionality and picture quality for a relatively low price. If you use your PC for a mix of work and gaming, this is a great alternative to OLED options that can be at risk of burn in. The HDR looks great, the dual mode resolution switch works very well and saves all of your options, and the usb-c 60w port is very useful for plugging in laptops, and charging phones. Some have said that the local dimming could be better, but I think that is only a problem when looking at the screen from an angle. When facing the screen forward, the local dimming does a great job of keeping the dark colors dark.I've seen some complaints of dead pixels, and bad packaging, but mine was packaged very well, and as of now, there are no dead pixels or black spots that I can see. Everything looks and runs well right out of the box, and I don't have any complaints.Are there better options out there? Of course! But for the price, its really hard to beat what this display has to offer, especially if you are upgrading from a 1080p setup. This manages to do so much, and I think the pros heavily outweigh the cons.

A perfect monitor for 1440p gaming
The monitor on the right is the Ktc one, the left is a Lenovo 24” 144 1080p monitor, you can easily tell which one is higher quality, I haven’t really tested the visual capabilities as I had intended to just plug it in and play, one thing I did not like was the fact that the monitor stand did not contain the necessary screws to screw it on, in which I had gotten lucky and found myself some, it arrived earlier than expected and runs perfectly fine, overall an amazing monitor especially for its price

Excellent Curved Gaming Monitor, Excellent Value!
Wow this new monitor I purchased for my gaming PC is a game changer! For approximatey $170, I have a 32" curved monitor which greatly improved my setup from my older 27" flat Asus panel (now used as a secondary display).A couple key items to note:One Button - The monitor uses a rear mounted single omni-ddirectional toggle button to control everything. Tap to open the monitor menu and adjust brightness etc. Long presss to turn monitor off/on, took me a minute to figure this out as I kept looking for a separate power on/off button along the base of the screen but there isn't one. A simple LED in the lower right corner illuminates white for on, amber for standby, and off when monitor is off.I haven't used the internal speakers for audio but if you are using these on a gaming PC setup I'd recommend using separate speakers. I recently upgraded my speakers as well to white Pebble Pros (see separate Amazon review for those).In terms of compatibility the monitor box included a power cable as well as an HDMI or Display Port (DP) cable for connection to your PC. Don't forget to connect your DP cable to your video card port and not your regular motherboard port. Using the DP is generally recommended over the HDMI unless your PC doesn't have a DP option.The included monitor stand is simple, Y metal design with rotating bezel to angle the screen up or down. I wish the stand were a couple inches higher, but the included base is adequate. You may end up wanting to raise your desk heigh to compensate for the slightly shorter stand height if the angle doesn't work for you.The picture quality and brightness are excellent, I have had no dead pixels or any other issues. I do recommend if you are using a multi display setup to match the refresh rate across monitors. Initially I had this one set higher than my other display and the monitor kept blacking out. Once I synced the refresh rates with the other display I haven't had any issues with black out.

Good quality - price monitor with some defects
I bought this monitor about two weeks ago for $165, which is a great price for a 210Hz 1440p display. Out of the box, the performance is very solid — the high refresh rate makes gaming feel smooth and responsive, and the image quality overall is quite sharp for the price point.Unfortunately, after just three days of use, I noticed a dead pixel. It seems like only the green subpixel is affected, so it’s only visible against darker backgrounds. On top of that, there’s a small patch of around four pixels that appear dimmer than the rest of the screen, which is only noticeable on bright backgrounds.These issues don’t completely ruin the experience, but they are disappointing given how new the monitor is. For general use and gaming, the flaws aren’t too distracting, but if you’re very particular about display quality, this might be a dealbreaker.Pros:Great price for 210Hz 1440pSmooth and responsive gaming performanceSharp image qualityCons:Dead pixel appeared within daysSmall dim area on screenQuality control could be betterOverall:For $165, the monitor delivers great specs and performance, but quality control is a concern. If you’re on a budget and can tolerate minor defects, it’s still a solid deal. If not, you may want to invest in a higher-quality option.

False advertising, specs are not true.
Not a 400hz monitor, max is 360.

Mi primer MiniLed
Mi primer monitor Mini led me gustó mucho tiene mucho brillo a veces demasiado que hasta lastima mi anterior monitor no tenía ni hdr 400 este me sorprendió mucho y más por el precio en el que lo encontré necesita una buena configuración que podrán encontrar en YouTube y que por cierto este monitor solo lo recomiendo si vez antes todas las reseñas en español porque si tiene algunos puntos malos como que de la nada se le baja el brillo aunque eso a mi no me molesta se ve fantásticos en juegos de campaña como Metro Exodus y Call of duty Modern Warfare 2019 o juegos como Fortnite o Arc Raiders .

Buen producto
Después de más de un mes de uso puedo decir que a cumplido con todas mis expectativas, lo combine con un Ryzen 7 5700x y la RX 9060 XT y no hay falla, parece que voy volando.

Excelente monitor, control de calidad cuestionable.
Me había gustado este monitor bastante, lástima el mío llegó con varios píxeles muertos y lo tuve que devolver, pero a primeras el monitor es súper ULTRA brillante si eres una persona que le gusta tener todo brillante es excelente, aparte el HDR se veía muy bien, el SDR nada fuera de lo común pero recomiendo usarlo sin local dimming. Este monitor es una joya si lo encuentras a un buen precio y si te llega con 0 píxeles muertos.
